Is Membrane Roofing the Right Choice for Your Home?

Membrane roofing, used successfully for decades in the commercial roofing industry, is also great for homes.


The traditional option of choice for a flat or slightly sloped roof was to build it up with layers of asphalt. But if you’re in the market for a new roof, you may want to consider membrane roofing instead.

What Is Membrane Roofing?

Have you ever patched a hole in a tire or seen someone else do it?

With the help of vulcanized cement, the patch bonds with and becomes a part of the tire. The hole is sealed, and the result is a strong tire that’s nearly seamless.

Membrane systems work in a similar way. Thin sheets of membrane are applied to the roof, and the seams are fused to create a strong, continuous surface.

Think of it as a little like shrink-wrap for your roof!

Types of Membrane Roofing Materials

Modified bitumen systems are often used for residences. This type of membrane roof uses the technology of a built-up roofing system, but adds reinforcing layers. These layers are made of a tough, resistant polymer. The seams between are sealed with a heat application process or a special adhesive.

Thermoset membrane roof systems are made of large, thick sheets of synthetic rubber. The seams are then heated, and the sections melt together into one continuous sheet. Due to the properties of the rubber compounds, the heat actually creates a chemical bond, so the entire roof is seamlessly strong.

Thermoplastic polyolefin (TPO) roofing is similar to — and nearly as strong as — the thermoset type. But TPO is typically less expensive, and thus more frequently used for home roofs. TPO roof sheets do not chemically bond when heated, however, so the seams must be fused together with solvents or by applying heat.

Advantages of Membrane Roofing

So why should you consider a membrane roof for your home?

First of all, the seamless construction means your roof will be waterproof. You won’t have to worry about leaks, an all-too-common concern for homeowners with flat roofs.

Also, because of its dark color, traditional asphalt roofing absorbs heat from the sun. As a result, the material expands and contracts, which leads to damage over time. In contrast, a membrane roof system is typically constructed out of a white or light-colored material that reflects the sun’s rays, allowing it to resist expansion and contraction.

A membrane roof is a solid, long-term investment, as it can withstand all types of weather. When installed correctly, this type of roofing can protect your home for 50 years or more with little required maintenance.
