Top 5 Myths About Spray Foam Roofing

Top 5 Myths About Spray Foam Roofing

Spray foam roofing is an ideal solution for retrofitting flat or low sloped commercial roofs in the Southwestern United States. Even though it has been around for decades, several myths about this roofing technology refuse to go away. The most persistent is that spray polyurethane won’t last on roofs. Research shows, however that successful foam roofing can last up to 50 years when properly maintained with periodic re-coating. In fact as far back as 1995, a study performed by the National Roofing Foundation indicated that customers rated foam roofs highly for durability and satisfaction.

Spray Foam is Expensive

This is another huge myth. Cost is comparable to a single layer of asphalt shingles. The cost of asphalt is on the rise, while spray foam pricing has remained steady, meaning that it could eventually become less expensive than asphalt.

Installation Can Only Occur in Perfect Weather

Application of spray foam roofs can occur during the same target temperatures as for other types of roofing. Moisture on the the substrate, however, prohibits application of foam or coatings, but experienced roofers have ways to protect the installation area so that work can continue. Applicators monitor weather conditions through weather reports and handheld electronic measurement tools.

You Can’t Walk on a Spray Foam Roof

The Spray Polyurethane Foam Alliance (SPFA) and National Roofing Contractors Association (NRCA) indicate that correctly applied SPF roofs can sustain up to 40 pounds per square inch or higher. A foam roof can support the weight of a normal person.

Spray Foam is Toxic

Spray foam roofs use a form of plastic that is similar to the plastic used in bottles that hold food products such as soda, ketchup, mustard and thousands of other items.

Spray Foam Does Not Insulate Well and is Not Energy Efficient

Spray foam is an excellent insulating option as closed-closed cell foam is used in the application. Closed-cell foam has high thermal resistance and can form tight barriers by filling in nooks and crannies that other roofing materials cannot. Foam roofs are highly water resistant and fire resistant and protect buildings against various types of pests. The insulating properties of spray foam can help reduce overall energy bills.
