Can You Install a Metal Roof Over Shingles?

A metal roof installation is a significant event in any homeowner’s life. Particularly when planned for and priced out. But the question remains: can you install a metal roof over shingles? While it is true that local building codes may allow homeowners to install a metal roof over shingles, this is not advisable. An insured and professional roofer will always recommend tearing off the previous roofing material, including shingles, before installing a metal roof. Why is this? To begin with, roofing material, such as shingles, is heavy and weighs on a home’s structure. Adding additional roofing material to existing roofing material creates an unnecessary burden on a home’s structure and foundation. Secondly, the metal roof installation will act perfectly well if not better without asphalt shingles underneath it.

What is the Best Underlayment for Metal Roof?

Traditionally, the most common roofing material that is used for a metal roof underlayment is non-perforated, asphalt-impregnated felt underlayment. It is important to understand that there are many types of felt underlayment including organic reinforced and inorganic reinforced.

What are the Disadvantages of a Metal Roof?

While there are many advantages to a metal roof, it is also important to weigh the disadvantages. Please review the following list to find out more.

  • Is it cost-effective? While it is true that metal roofs only need to be replaced once in a lifetime, that doesn’t mean that metal roofs are inexpensive. Asphalt shingle roofs typically last around thirty years, and they are less expensive than metal roofs.
  • Is it noisy? A metal roof that is installed without the proper insulation and precautions will be understandably noisier than an asphalt shingle roof, particularly during weather events like rainstorms and hail storms.
  • Is the color preferable? When selecting a metal roof installation, it is important to consider the color choice available. Many homeowners understandably want their roof installations and the associated color palettes to blend into the neighborhood. Please make sure to consult your local insured roofing contractor to discuss your color options.

Can You Install Metal Roofing on Plywood?

In order to install metal roofing on plywood, you need to first make sure that the plywood deck is strong enough to withstand the added weight of the metal panels. In order to make sure that the integrity of the plywood is sustained, install waterproof felt over the plywood to protect against any moisture. It’s no wonder why many homeowners consider metal roofs to be a compliment for their homes. After all, metal roofs are very energy efficient and, as previously mentioned, only need to be installed once per lifetime provided that the metal roof is installed by a professional roofing company.

Do You Need a Vapor Barrier Under a Metal Roof?

As previously mentioned, it is always important to install an adequate moisture barrier underneath the roof covering. For solid sheathing, professional roofing contractors are advised to use thirty-pound felt paper. The reason why a vapor barrier is important is that if airborne moisture does happen to seep into a metal roof assembly, and condenses, it will cause some problems in the long-run. With a vapor barrier, this problem is minimized.
