There are certain sections of a roof where roof flashing is critical in the safety of your roof. Those areas include where walls and roof surface meet, roof valleys and protrusions like the skylight and vents. Roof flashing is critical around the chimney and at the roof edge too. 

What are the different types of roof flashing?

There are several types of roof flashing, each have a specific purpose. A partial list of those different roof flashings is: 

Common Roof Flashing Types:

• Continuous roof flashing: A long piece of continuous roof flashing that protects where a vertical wall and sloped roof meet. 
• Drip edge roof flashing: Usually installed along the eaves under the roofing felt to keep water dripping off the roof. 
• Step roof flashing: A rectangular piece at a 90 degree bend in the center used in an overlapping manner that prevents water from getting behind the walls.
• Valley roof flashing: A metal flashing in a W-shape that is installed on top of roofing felt where two roof valleys join.
• Vent pipe roof flashing: This cone-shaped flashing installed around vent pipes over the shingles.

Additional Roof Flashing Types:

• Base roof flashing: Fits around chimneys to ensures rain is redirected out and down the roof. 
• Counter roof flashing: Installed opposite to or above base flashing as the second part of a two-part roof flashing team.
• Cap roof flashing: This L shaped roof flashing is installed to lay flat against the roof, windows, and other fittings to ensure water runs off  such as windows. The shape of the structure runs the other direction and off the roof. 
• Chimney roof flashing: Roof flashing is necessary around chimneys to prevent water from pooling in the gaps between the roof and the chimney. 
• Saddle roof flashing: This flashing covers any protruding beams or attached railing.
• Skylight roof flashing: Most skylights have built-in roof flashing to keep water from seeping around and inside the house. If a skylight doesn’t have this flashing the roofing contractor will install one.
• Kick-out roof flashing: This roof flashing bridges any  gap between the step flashing and the gutter to direct water to the gutter. 

What is counter flashing in roofing?

Counter roof flashing prevents moisture from getting behind a headwall or sidewall vertical flashing. In some cases, a roofing contractor will use the exterior wall-covering as the counter roof flashing, but most common is a separate counter roof flashing installed.

What is drip edge flashing?

Drip edge roof flashing is a flat thin metal flashing installed at the roof edges to control water flowing away from the fascia while it protect the underlying roof components. 

Does flashing go over or under shingles?

It depends actually, roof flashing is installed both ways. Picture rain coming down on your roof with the wind blowing. You need something in place to divert that rain before it gets behind or under the shingles. 

So, installing the roof flashing over the shingles may be the best scenario for one area, where installing roof flashing under the shingles may work better in a different area of the roof. Roof flashing should be installed so that is diverts water around any protrusion skylights and vents, or were the shingles are parallel to the wall, install flashing where water can’t get under the shingles. 

Which is better aluminum or galvanized flashing?

If you’re looking for long lifespan with durability, aluminum roof flashing is the best choice ad easy to install. If cost is your concern, galvanized-steel roof flashing is your best option, but isn’t as durable and may need replacing before the roofing material does. 

Is roof flashing required by code?

If you’re asking about building codes, that can vary from city to city, county to county. You’ll need to check with the local governing offices for that information. If you are asking about the roofing material manufacturer, most will require roof flashing be installed at the time the new roofing material is installed. The roof flashing used must follow their design and system with proper material application requirements followed.

1. People: This is more common commercial structure, and while it sometimes necessary and should be OK to walk on a commercial structure’s  roof, it should be a modest amount of foot traffic. The roofing membrane on commercial roofing isn’t meant to be used as a walking pads, but because of HVAC and other equipment, it is necessary. Too much foot traffic, dropped equipment and tools can lead to a leaking roof. 
2. Seams: Again, a common issue for commercial structure where roofing membrane has seams, they are the weak points of a roof. Roofing membrane comes off large rolls that are rolled out over and then attached by adhesive or mechanically fastened. Residential roofing has weak seam-like areas around chimneys, vents, and where two different roofing angles meet. 
3. Neglect: Skipping monthly roofing inspections of commercial or residential properties can leave your roof susceptible to disastrous consequences. Routine inspections and maintenance is necessary to catch issues like torn membrane on commercial property and loose or missing shingles on residential properties. Making sure drainage is clear and working, gutters are attached, and downspouts are clear. Regular monitoring of any roof is key to avoiding a leaking roof. 
4. Weather: This is something that nobody has control over but can do a lot of damage to commercial or residential roofing. Both are constantly exposed to the elements. The ice, rain, snow build up on rooftops and over gutters, downspouts, and drains. For commercial property, this leads to ponding water which will eventually lead to a leaking roof if not caught and fixed in time. For residential roofing, the same elements can clog up the gutters and downspouts, cause the rain and snow to seep up under the shingles, on to the decking, into the attic and a leaking roof is created!  Again, routine inspections of both properties is essential in catching these issues before they become a problem and leaking roof. 

Not every leaking roof can be blamed on these four factors, but they are factors that can be caught before they cause a leaking roof. Prevention is best way to avoid leaking roofs and  repair. 

How do I stop my roof leaking in heavy rain?

When your roof leaks with heavy rain, getting a professional roofer out immediately isn’t always possible. Here are a few tips to stop a leaking roof temporarily. 

• LOCATE THE SOURCE: Before you can stop the leaking roof, you need to find where the leak is located. It may not be the roof itself, but a drain, gutters, downspouts, seams, loose or missing flashing, etc. 
• CLEAN THE AREA: Once you have located the source, prepare the roof area and the area under it for your temporary repair of the leaking roof. Place plastic tarp or towels and buckets under the leaking areas to catch any more water. If there is bulge in the ceiling, use a screwdriver to poke a hole in it and let the water out. 
• APPLY A ROOFING TAR: Roofing tar is to a leaking roof that duct tape is to other things! On a residential roof, if the shingles are loose, use the roofing tar to hold it in place. If the shingle(s) are missing, then place a piece of wood over the leak and secure it with the roofing tar. Same is to be done with a commercial roof, find the leak, either place plastic or wood over the leak and seal it down with roofing tar. 
• PLASTIC COVER: If you used a sheet of plastic, nail it down in addition to the roofing tar to secure it in place and keep as much water out as possible. Remember, this is only a temporary fix to your leaking roof, you’ll still need a professional roofing contractor to fix the roof properly. 
• SEAL UP JOINTS and SEAM: Be sure to apply the roofing tar over any joints or seams where you have temporarily fixed the leaking roof. 

Who can fix roof leaks?

For a commercial or residential structure, any roof look should be inspected, repaired, or replaced by a certified, insured, licensed roofing contractor.  Once the inspection has been performed and a written estimate is received, call your insurance agent if you haven’t already. 

Can leaking ceiling collapse?

Absolutely!  Depending on the age of the structure and the stability of the roof frame, ceiling collapse isn’t always likely, but possible. Any leaking roof indicates that there is possible water pooling up between the ceiling and the roof. That pooling water is adding more weight on the entire structure, including the roofing beams, drywall, and insulation. That weight will cause the ceiling to droop and sag, and a leaking roof left unattended can lead to a collapsing ceiling. 

For the sake of your insurance liability, the stability of your commercial structure or home, it is essential to perform regular roof inspections yourself. Even the smallest, undetected roof leaks can cause mold, creating an unhealthy environment for your employees or family. Call 610-689-3737 today for emergency roof repair in Oley, PA.

Is it worth it to replace windows?

If you’re thinking about replacing your windows, are you making a good investment? Many factors will influence the value of a whole-house window replacement that include:

• The type of windows you choose: Different types of windows will cost less than others but might not provide the energy savings you’re looking for. You’ll spend less on standard double-pane vinyl-framed windows but wood-frame windows are often more energy efficient and save you more on energy expenses, depending on the climate. Vinyl windows, however, will require fewer repairs.
• Your current windows’ thickness: Thicker windows provide greater protection and are more energy-efficient. Installing newer, thicker windows may save you on energy expenses.
• The current window frames’ condition: Worn-looking windows not only diminish your home’s curb appeal but also leave your home open to more drafts and less protection from the elements overall.
• The climate in your area: Newer energy-efficient windows are especially valuable in areas in which you have four discernible seasons. Yearly energy savings will cover installation costs in just a few years.

Can I replace a window myself?

In general, when it comes to window replacement, it’s usually best to let pros handle the job, in particular when you’re replacing all your windows. A replacement job can be time-consuming, especially when putting in full-frame windows. Full-frame windows—the kind used in new construction—take about four to six hours at a time to install, even for professionals with the right tools and skills. In other words, it’s more than a weekend project to install a whole home’s windows.

On the other hand, putting in a single window might be the perfect project for a DIY enthusiast with the right skills and materials. This is especially true if you’re just planning to install window inserts, which are window sashes inside a small frame that fits into your current window jamb. Inserts are installed inside the home and take about half the time to install as a full-frame window.

Is window replacement messy?

Like most other home improvement work, putting in new windows is messy work. Much of the mess is created by dust, so the work area needs to be protected. Any furniture or other items that can’t be moved should be covered with cloth or plastic. Replacing your windows also involves a lot of scraping off paint, as well as sanding, painting, gluing, and drywalling.

What time of year is best to replace windows?

When planning a window placement project, it’s usually best to wait until warmer, drier weather is forecast, which makes spring or early summer ideal. If it’s too cold, drafts will be difficult to contend with. When it’s too hot, it will make your workspace really uncomfortable. At the same time, you’ll have an easier time finding installers in colder “off-season” months.

Which home replacement window is best?

There are several great brands and styles of windows on the market today. When shopping for the best window for your home, you’ll want to consider these options:

• Window style: Styles range from double-hung windows that fit classic architectural styles such as colonial style to specialty styles to fit custom designs.
• Window frame: While wood frames are still common, many people are choosing vinyl or aluminum frames because they require less maintenance and are often less expensive. They are also much easier to customize.
• Window glass: There are multiple glass types from dual- and triple-paned glass to panes infuses with gases like argon and krypton for improved efficiency.

What are standard replacement window sizes?

Standard replacement window heights and widths vary:

• Widths: 1-foot, 2-inch to 2-feet, 11.5-inches.
• Heights: 2-feet, 5.5-inches to 6-feet, 5.5-inches.

What is the window replacement program?

Window replacement can prove to be an expensive project. Sever government programs, such as the Weatherization Assistance Program from the Department of Energy, are available to assist people with low- to moderate-incomes, as well as seniors and other groups. This program and similar programs encourage people to make home improvements that conserve energy.

When should you replace siding?

Cracks and holes are apparent signs that siding needs to be repaired or replaced, you know that, or you wouldn’t be reading this right? The damage could be from basic wear and tear or it could be from tree limbs falling or footballs getting kicked into the house. Some damage isn’t visible from the street, but up close, you see the damage and you know that can’t be good for your home. 

If you are spotting any of the following, siding repair may be possible, or you may need to get some quotes for new siding: 

• Chips, dents, holes: These are the most obvious damages and create an open invitation for bugs, mildew, and mold to work in under the siding and start working on the structure of your house.  Siding repair with holes, dents, or chips is usually possible if the damage isn’t widespread and already spread too far underneath. 
• Cracked or loose siding: Cracks, gaps, and loose siding will allow water to seep under the siding and into the interior walls of your home. Fortunately, siding repair is possible for these types of damages.  
• Dry rot: The exterior of the siding may look okay but under the siding, if there is any rot started, it is beyond siding repair. 
• Frequent repainting: When the siding of your home needs frequent repainting, it has lost its waterproofing ability and is time to be replaced. 
• Bubbling or warped panels: Siding that bubbles or warps is the result of extreme weather damage and heat.  If siding repair isn’t done to fix the bubbles and warps, under the siding will be exposed to the elements and bigger problems will begin, resulting in new siding needed.  
• Fungus, mildew, or mold: When you notice any type of growth that is moisture-related on the underneath side of the siding panels, you have a leak somewhere that needs to be addressed. If caught soon enough, siding repair is possible. 

Can you replace one piece siding?

Thanks to the invention of the ‘zip tool’, yes, you can do siding repair for one piece now!  With this handy tool, available at big box home improvement stores or online, you can replace that one piece in under 30 minutes.  The only downside, if your siding is more than 2 or 3 years old, the color may be off a little bit. You can have custom paint made to match the existing siding if the difference is too noticeable. Here are basic steps using the zip tool and new piece of siding to repair that baseball bullseye.

• Start at one end of the piece that is damaged and push the zip tool end under the siding until it hooks to the bottom lip.
• Sliding the zip tool along, release the vinyl siding from the bottom edge, releasing it from the piece below.
• Pulling the zip tool down and out, unhook the bottom lip, sliding along the edge and pull out the siding as you go along.
• Then unzip the vinyl pieces above the damaged vinyl piece.
• Behind the vinyl siding, slip a flat bar and raise the nails out.
• Slide the replacement vinyl piece up , pushing it into place until the lower lip is locked into the lower piece.
• Drive roofing nails through the flange, spacing the 1-1/4” nails every 16 inches.
• Nail in the center of the slot, leaving 1/32”  of space between the nail and siding to allow the vinyl some movement. 
• With the new piece in place, using the zip tool to lock the piece above the replacement piece down over it.
• Starting at one end, pull the lip down as you twist the siding zip tool with slight force that leads the edge down.
• Sliding the zip tool as you push  in on the replacement vinyl just behind the tool to snap it into place.

How many years does siding last?

On the average, vinyl siding last up to sixty years. This popular choice for most homeowners requires little effort of maintenance, occasional cleaning for aesthetic purposes and removing algae and mold. With a good quality vinyl siding that is professional installed and with  scrupulous care and maintenance, your vinyl siding can last 100 years!

Impact resistant shingles have a thicker gauge base and are made with materials that are more flexible than standard shingles. They are rated for their durability during the UL 2218 impact test and given a Class 1, Class 2, Class 3, or Class 4 based on the impact degree they can withstand and crack.

A Class 3 rating is given to shingles that do not crack after being hit by a steel ball, measuring 1.75” in diameter and dropped from twenty feet. Class 4 is the highest after taking a hit from the same twenty foot height with a two-inch steel ball. To pass the UL 2218 test, the shingle cannot be cracked after that impact. 

How can you tell if shingles are impact resistant?

Impact resistant shingles are manufactured in a multilayer and thicker than the standard asphalt shingles. The impact rating of UL Standard 2218 Class 4 will be on the underside of the shingle.

How much more do impact resistant shingles cost?

Are impact resistant shingles worth it?

The real question isn’t whether impact resistant shingles are worth the cost. They aren’t even a profitable option for homes where hailstorms are rare. For a home where hailstorms are almost as normal as the sun rising each day,  impact resistant shingles are a great investment.      

What roof is best for hail?

With high winds and atmospheric conditions all just right, hailstones can do a lot of damage to a roof. That is why homeowners want a roofing material that is hailstone resistant, but affordability is important too. Here are three of the best roofing materials as determined by most roofing contractors: 

• Rubber Roofing: A rubber roof is a great solution for hailstorms. It has a tremendous impact resistance level because it absorbs and disperses the impact. due to its energy absorbing and dispersing nature. Additionally, a rubber roof can flex with the temperature swings from one extreme to the next. 
• Asphalt Shingles: Asphalt shingle roofing is the most popular because of it’s inexpensive pricing. However, it the standard asphalt shingle doesn’t fare well in hailstorms with significant sized hail. You would need to upgrade to a Class 4 impact resistant shingles, which is better again hailstorms but more expensive. 
• Metal Roofing: Metal is the most durable roofing material. It is fire-resistant and lightweight, providing a long lifespan. Today, metal roofing comes in a variety of colors and is UV resistant, a bonus for homes in area that see high temperatures. The type of metal and it’s thickness makes a difference how resistant it is to hail storms.

How do you know if your roof has hail damage?

The first place to look for signs of hail damage is the gutters. A hard-hitting, high-impact hailstorm will dent the gutters and downspouts. If they are dented, then you can almost be sure there is hail damage roof above. What damage does hail do? Any of the following are indications of a hail damage rooftop: 

Asphalt Granules Loss

Asphalt shingles feel like rough sandpaper from the top layer of granules. When hail has beat on a roof, those granules come off and fill the gutters and downspouts. After a hailstorm, check the downspouts for dents and if they are full of asphalt granules.

Cracked Shingles

High wind or hard impact hail, damage roof indication are cracked shingles. Cracked shingles expose the layers under the roof, subjecting it to the weather and the UV rays. 

Fiberglass Matt Exposed

Impact of hail damage the rooftop by shattering the shingled surface, leaving the fiberglass mat exposed, which gets fractured by the hail, cracking and tearing it, exposing the decking. 

Self-Seal Strip Weakens

High winds and hail damage rooftops include the weakened shingle seals, putting the shingles at risk of blowing off and exposing the entire roof to the elements. Missing shingles are permanently compromising the roof integrity. However, some granule loss is normal. It isn’t always an indication of hail damage rooftop. 

How do you know the difference between hail damage vs normal wear? If the granule loss you see on your roof a uniform pattern, this is considered normal wear and tear. A hail damaged roof will have actual impact indications. The asphalt shingles will show impact points like somebody took a hammer to the roof.  The insurance inspector or a professional roofing contractor can differentiate the hail damage roof and the wear and tear roof. 

Can hail damage be completely repaired?    

Coverage and terms vary between insurance companies and within each policy, including a time frame to file a claim for hail damage with roof. Proof and timing are both critical when filing claims on any insurance, and homeowners may be the most stringent of all insurance claims. 

So, should I replace my roof after hail?

Your homeowner’s insurance will be the power to decide if your hail damage roof warrants replacement or only needs repairs. However, there are clear-cut indications that a replacement is necessary; for example, the roof is gone or partially missing if there is enough widespread damage that your roof is leaking when it rains. 

Then there are some cases where what appears to be an extensive hail damage roof can be repaired and give the roof another few years of life. Again, these are decisions the insurance adjuster will make, and it is also why you need to have a professional roofing contractor inspect your roof. Ideally, the insurance adjuster and the roofing contractor are there at the same time. 

Are there different grades of asphalt shingles?

As far as different grades the improved version of asphalt shingles was developed in the 1970s in order to provide thicker and more protective materials. These shingles are referred to as the premium product option for asphalt roofing and are named as architectural shingles.

What is the difference between architectural shingles and asphalt shingles?

Asphalt shingles are typically 12 inches wide with a basic three-tab style and shape. They are able to protect against stable weather or mild inclement weather. If increased protection against wind, water, and impact are desired architectural shingles are three times as thick. What’s more, they can come in a variety of colors and shapes to fit with various aesthetic preferences. They are also referred to as dimensional or laminate shingles in the roofing market.

Can you coat a shingle roof?

You may be able to use a roof sealer with your asphalt shingles so that extra protection can be made. Two coats will be sufficient as the first will be absorbed whilst the second will provide the protective layer necessary to stop cracking, granule loss, leaking and curling.

Which is better light or dark roof shingles?

In general with roofing materials, lighter colors are better for energy efficiency purposes. Light colors will deflect the heat and keep temperatures down in hotter climates. Darker colors will adversely absorb heat yet this may be beneficial with colder areas. Darker colors will also help ice and snow melt from your roof faster.

How long do asphalt shingles last?

Asphalt shingles are known to last for 15-20 years depending on the conditions in which they are kept.

How do you make asphalt shingles last longer?

You may be able to make asphalt shingles last longer by avoiding power washing which can loosen granules and the material’s top coating. Another way to make your roof last longer is to keep up with clean gutters as water damages can spill over if water is not properly drained. Finally, make sure that the ventilation and attic insulation is in proper condition in order to avoid inconsistent heating and cooling of the roof.

How do you tell if your shingles need replacing?

There are several ways that you can see if your asphalt shingles will need replacement. First, consider the age of your roof. If it’s nearing the end of it’s natural roof life a replacement is recommended before problems benign to emerge. Such issues as shingles curling, granules missing, and buckling can be a sign that roofing materials are wearing out. Another issue can be with widespread water damages which can cause mold to grow or water infiltration to wreck underlying materials. With roofing punctures you may see leaks or waterlogged supportive beams which can compromise the roofing structure. Pay particular attention to the weak areas of your roof such as with chimney flashing or valleys as these can hold damages which will cause a need for a roof replacement.

Is it better to remove old shingles?

Although most states allow you to have a second layer of asphalt shingles over older ones consider if your roof is severely damaged or if there will be ventilation issues. Another thing to consider is that you will be adding more weight to your roof and if your roofing structure can not handle an extra layer of shingles it may be best to take off older asphalt shingles before reroofing. Speak to a roofing professional so a roof inspection can be made to gauge the specifics of your roof and what can be supported with the overall structure.

Can you patch a flat roof?

Patches are often used for flat roof repair, particularly for rubber roofs like EPDM. Patches can often prove to be permanent fixes for holes or leaks in this type of roofing. Sealants like caulk or bitumen tend to work the best for other types of flat roofs.

How do you stop a flat roof from leaking?

No matter what kind of material your flat roof has, leaks are a common problem. Even though flat roofs aren’t actually completely flat, drainage is still not very good. This poor drainage causes water to collect on the roof, and that often leads to leaks. If there are cracks or holes in the roof, the roof becomes vulnerable to leaks. With flat roof repair, you can temporarily stop leaks following these steps:

• Find the leak first inside the building, measuring from nearby walls to where you suspect the leak.
• Go up on the roof with your measurements and search for the leak. Search for damage on the roofing membrane or around flashing and vents.
• Damage may appear as blisters or cracks or the phenomenon known is alligatoring, in which the roof has cracked because it has dried. The cracks look like alligator skin. 
• Once the source of the leak is damaged, remove any debris around the leak.
• Dry the area around the leaks before you start working on it. You don’t want to trap any moisture under the repair.
• The damage area has to be cut to remove moisture.
• Once the open membrane is dried, you apply roofing cement under the membrane and seal the leak with it.
• Nail the membrane flaps down to secure them and seal the leak.

What is the best material for a flat roof?

There are multiple types of flat roofs available and the best for your building will depend on several factors. The type of industry you’re in will often affect your choice of roofing. For instance, if there is heavy chemical exposure, PVC roofing is a great choice because it holds up well against a variety of chemicals. If you are looking to cool your roof and improve your building’s energy efficiency TPO is a really good choice. In fact, many businesses are choosing TPO and similar single-ply membranes for that reason. These roofs also require less flat roof repair.

How many years does a flat roof last?

Flat roofs are made from a variety of materials. Each type of flat roof will age differently, but most flat roof membranes typically last somewhere between 20 to 25 years under ideal conditions and maintenance. Some like PVC will last much longer. At the very least, a flat roof should be expected to last 10 years. Quality of installation, climate, and maintenance will affect a roof’s longevity.

Flat roof repair or replacement

Because problems like leaks might be common on flat roofs, making the decision between flat roof repair or replacement may not be all that straightforward. As with any roof, age will play a big role in the decision. You can expect most flat roof membranes to last anywhere between 20 to 25 years before they do need to be replaced. Even then, you may want to have your roof inspected to see if it needs to be replaced. 

More often than not, repairs will keep you from having to replace your roof until it’s service time is up. One option many building managers consider is a roof restoration coating. These coatings can extend your roof’s life for years, saving you the expense of replacement. They will also improve your roof’s energy efficiency, so you’ll save money on energy expenses as well.

Flat roof repair in rain

High winds and heavy rains can be flat roofs’ worst enemies. Rain, in particular, makes these roofs vulnerable to leaks. If you need flat roof repair, it’s normally best to do the repairs in clear weather, especially if there are particularly high winds involved. Of course, with some repairs it’s not necessarily good to wait until the next clear day. You can make repairs in the rain on a flat roof. If you do hold off on repairs, make sure to have a professional roofer come out and place a tarp over the roof to protect it from further damage.

Flat roof repair in winter

Winter can be a particularly tough time for flat roofs. Because of drainage issues, flat roofs can be vulnerable to ice dams. These walls of ice that form along the edges of the roof can put a halt to proper drainage and will need to be removed. Bad seams are a problem year round, but heavy snowfalls make damaged seams even more susceptible to water seepage and leaks. Constant freezing and thawing, as well as the heavy weight of ice and snow, also puts a strain on the roof as a whole and it’s in the winter when we see cracking occurring most often.

• Structural: A roof inspection is looking for signs of sagging and uneven roof planes. The fascia, gutter system, and soffit are inspected as is the chimney for chimney caps are in excellent condition and in place, and cracks or crumbling grout in the masonry. The roof inspection will also include time in the attic to check the venting is adequate and working.
• Material: This part of a roof inspection is to look at the shingles. Are there any curled, damaged, loose, or missing? They look for algae, lichen, moss, rust, or stains and missing fasteners or flashing. The roof inspection will include checking for aggregate in the roof valleys, gutters, and on the ground, and checking for any deterioration or gaps at the rubber boots around vent pipes.
• Interior: Because a roof leak will ultimately damage the interior, a roof inspection includes checking the attic, ceilings, and walls for water damage and stains. This includes looking for any mold or rot that a roof leak could cause.
• Workmanship: A thorough roof inspection will include checking the workmanship of the roof install like flashing installed wrong around all roof penetrations like the chimney, skylights, and vent pipes. 

How do you perform a roof inspection?

A roof inspection checklist should include the following areas:

1. The roof covering – does it provide a barrier against the weather?
2. The fasteners – roofing nails should be corrosion resistant and driven straight so they are flush and snug without going too far in.
3. The decking and underlayment – is it properly installed?
4. The slope – is the layer of roof protection adequate for the degree of the slope and is there water and ice-dam protection?
5. Ice barrier – this should be at least 24 inches inside the building’s exterior wall.
6. Drip edge – should be a metal material that is installed at the eaves and rake.
7. Offset pattern – is the offset pattern in line with the manufacturer’s guidelines for shingle installation?
8. Roof valley flashing – are the shingles lapped on both sides of the valley and meet the minimum width?
9. Nail penetration in decking – are the nails long enough to penetrate the decking without going through the shingles?
10. Flashing – are all areas that required flashing in place? The penetration flashing, vertical surface flashing, skylight flashing, and steep to slope transition?

With these ten roof inspections points covered, any damages or irregularities can be spotted, and repairs or replacement scheduled. Or in the case of buying/selling a house, this is often a point of negotiation on pricing.

When should I get the roof inspected?

Your life is full of preventative maintenance. From your car to your health to dental visits for the kids, and then there is your home. Preventive maintenance there includes changing the smoke alarm batteries, HVAC filter, and the roof. Yes, a roof inspection is needed for preventive maintenance too.

In the perfect roof inspection world, a professional does a roof inspection annually, typically early fall. At the minimum, a roof inspection should take place five years after a new roof is installed, and then subsequent roof inspections should take place at a 10-year anniversary, then 13 years and 15 years. After the 17^th year, it will be time to get quotes for a new roof, because it will have maybe three more years of life expectancy.

What is considered roof damage?

If you have any of the following, you need to have a professional roof inspection soon:

1. Water Damage – Roof leaks are often apparent on the interior of your home with water stains on the ceiling and walls. In the attic, you may find moldy areas or water spots on the rafters
2. Shingles – Curled, loose, or missing shingles.
3. Fascia and Soffits – Any signs of deterioration around fascia and soffits.
4. Granule filled Gutters – Asphalt shingles will shed granules when they are damaged or worn out.
