How do you repair a flat roof?

When you have a flat roof, whether commercial or residential, your roof can be vulnerable to damage. As with other types of roofs, flat roof repair will vary depending on the type of material involved as well as the type of damage. An asphalt or modified bitumen roof can be resealed with bitumen or caulk, while EPDM or PVC roofs can often be repaired with adhesive patches. On any of these types of roofs, usually the easiest thing to identify will be cracks, tears, or punctures. You’ll want to repair the largest areas first, as they’ll be the most vulnerable to leaks, but smaller tears need to be addressed as soon as possible.

Any damaged area that opens itself up to water getting in it should be the first priority for any repairs. Among the most vulnerable areas on a flat roof for damage and leaks are the seams. You must be diligent about checking the seams for cracks and holes. When you are making repairs, you’ll want to always clean the area, clearing of the debris before getting started on the repair.

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.
