Surprising Myths About Foam Roofing

Foam roofing is not a new option or process; blown foam has been used on roofs for several decades, and is considered a lightweight and easy-to-install alternative to traditional asphalt shingle roofs or metal roofs. A foam roof is a good insulator for a building and can be less costly, but many building owners shy away from having a foam roof installed simply because they don't understand how the material works or how it's applied.

Consider some surprising myths about foam roofing and the materials used to apply it, and you might better understand why it's a good choice for the roof of your commercial building.

Myth #1: The foam is dangerously toxic.

The polyurethane foam used for foam roofs is the same type of foam used in foam mattresses and to seal refrigerators. It is also used in foam pillows and couch cushions. This foam is actually a type of thin plastic with tiny air bubbles trapped inside and while it's not safe to ingest, it's inert when used in these types of applications and causes no more health or environmental problems than any other foam product you have at home.

Myth #2: Water breaks down a foam roof.

If water could break down a foam roof, it wouldn't last past its first rainfall. The type of foam application used for a roof is not like foam produced by a can of shaving cream or other aerosols, which are water-based and injected with air. The type of foam used for a roof is built with a foundation of plastic, and air bubbles are injected into it and then it is sealed. It is as waterproof as any other type of roofing material.

Myth #3: A foam roof is not very durable

Many foam roofs have stood the test of time. Polyurethane is durable, yet flexible, so it is often used on the soles of shoes and other such applications. A foam roof, with proper maintenance, is meant to last the lifetime of your building.

Myth #4: A foam roof will change shape, like memory foam mattresses.

While the material of foam mattresses and a foam roof are the same, their composition is very, very different. A foam roof is made of a much denser composition than a foam mattress. The less dense composition is what allows a foam mattress to change shape with pressure, whereas the density of a foam roof allows it to keep its shape and to stay solid.
