Interested in Spray Foam Roofs? Expert Answers to 4 FAQs

Interested in spray foam roofs for your home? We have all the answers to frequently asked questions about this efficient and eco-friendly roofing system.

Your roof keeps your property in tip-top shape and boosts your safety and comfort. Over time, you may encounter roof issues, and one way to address them is by using spray polyurethane foam (SPF) roofing. This offers air, moisture, and thermal barriers that can fix your roof problems conveniently and quickly. If you are interested in trying it and want to learn more about it, read the SPF roofing basics below. 

What Is Spray Foam Roofing?

Spray foam roofs are a watertight roofing system that contains spray polyurethane foam, silicone coating, and granules. This works by producing a foam made from combining and heating two chemicals and sprayed right onto your unique roofing system, creating a slope for liquids to be directed towards drains.

A thin layer of silicone coating is installed over the foam to prevent it from getting damaged by the harsh UV rays. The silicone coating is installed twice, with the topcoat containing granules for additional strength and friction to ensure safety when walking over your roof.

What Is the Cost of  Spray Foam Roofs?

When getting your roof fixed, it’s vital to consider your budget. A spray foam roof costs around $4–$7 per square foot on average. However, this is not a fixed price since the cost varies depending on various factors, such as your home’s location, your current roof’s condition, your existing roof system, and your height’s property. The project is more likely to be more expensive when you live further away from your spray foam roofing contractor, you have a leaking roof, your roof is made with gravel or stones, or you have an inaccessible roof.

What Are the Potential Problems You Can Encounter with Using Spray Foam Roofs?

While spray foam roofs can be beneficial for you, this can cause you potential problems along the way. For instance, if you hired an inexperienced or unprofessional contractor, you may encounter problems with the installation. The temperature needs to be at least 50 degrees to apply spray foam; otherwise, the foam will not perform well. Furthermore, the foam is light, which means it can be carried away by the wind and land on nearby cars and other areas it wasn’t supposed to. 

When you hire experienced contractors, you won’t get worried about encountering such problems. Make sure that they are certified with the Spray Polyurethane Foam Alliance (SPFA) before hiring them to avoid delays and other inconveniences in your project.

What Are the Most Compatible Roofing Systems with Spray Foam Roofs?

Not all roofing systems are ideal to be applied with spray foam. Others need some tweaking before application. Some roofing systems that are most appropriate and can be installed right over with spray foam are metal roofs, TPO roofs, fully-adhered EPDM roofs, smooth or gravel-surfaced built-up roofs, and existing modified bitumen roofs.
