Learn How to Debunk These 9 Common Spray Foam Roofing Myths


Spray foam roofing is a versatile and cost-effective way to revitalize and seal flat or low-slope commercial roofs. So why do all of these spray foam roofing myths exist? Some of these myths have been around since the 1960s—when sprayed polyurethane foam (SPF) roofing systems first saw use in commercial roofing projects. Other misconceptions started when inexperienced roofers incorrectly installed SPF roofing systems.

However, no matter where these spray foam myths came from, we at CD Beiler Commercial Roofing are here to debunk nine of the most common foam roofing myths.

1. Spray Foam Roofs Are a Short-Term Solution

One of the most common spray foam roofing myths is that SPF systems are a short-term solution, non-durable, and will not last as long as other roofing materials. However, spray foam roofing uses a closed-cell system, which offers durable and leak-proof protection for your commercial roof.

If applied correctly, these roofing materials can last up to 20 years or more and withstand almost any weather conditions. Especially resistant to wind and rain, spray foam roofing makes for a seamless and dependable roofing material that can even strengthen your roof or commercial building.

Always make sure you have a professional roofing company, like CD Beiler Commercial Roofing, install your foam applications to ensure you receive all of the benefits that SPF roofing materials offer.

2. Birds Will Attack or Tear Apart Your Roof

Birds are problematic for any commercial roofing system, but many believe the foam roofing myths that birds will attack or tear apart your spray foam roofing system. Even though birds may flock to any flat surface, that doesn’t mean they will cause damage to your roof.

While birds may try to nest or take nesting materials from your roof, a properly applied SPF roof will not allow birds to damage or remove any of the spray foam material. Once SPF hardens, the durability of its outer shell can withstand most weather conditions and will undoubtedly prevent damage from birds.

3. Spray Polyurethane Foam Contains Toxic Chemicals

Sometimes foam roofing myths start with a bit of truth—it is important to note that before curing, SPF roofing materials may be toxic. However, once fully cured, SPF roofing materials are safe and non-toxic.

For this reason, it is essential to hire a professional roofing company that has experience with spray foam roofing. A professional and experienced roofing contractor will know what safety precautions to take and when, or if, you need to vacate the building during installation.

4. Spray Foam Roofs Are Not Suited for Walking On

As mentioned above, spray foam roofing is durable. Whether you need to inspect your roof to check for damage from a storm or you find yourself needing maintenance for rooftop HVAC equipment, you should have no problem with foot traffic on your SPF roofing system.

With that in mind, be careful of the tools and equipment you or other workers bring to your roof. While SPF is incredibly durable, misplaced tools may still puncture your roofing system. If you do find that there’s been a puncture, contact us at CD Beiler Commercial Roofing to come and assess the damage with a free, on-site roofing inspection.

5. Foam Roofs Are Expensive

Another one of those pesky foam roofing myths that won’t seem to go away is that foam roofs are expensive. Any commercial roofing project is an investment in your building, as you are adding a layer of protection that should last for years—in this case, up to 20 years or more. Why not make an investment that will also help save you money in operating costs?

Spray foam roofing not only adds a layer of protection for your building from the elements, but it also helps keep your building cool in the summer and warm in the winter. An SPF roofing system adds a layer of insulation during the winter to keep heat in your building and includes a reflective coating for the summer to keep your building cooler.

6. Foam Roofing Is Difficult to Install

The biggest concern with installing foam roofing is the weather, but that is the same concern for any commercial roofing system. Hiring an experienced spray foam roofer will eliminate any possibility that your spray foam applications will be challenging to install. A professional roofer with experience in spray foam roofing will know when it is best to install your new roofing system.

7. Spray Foam Roofing Material Absorbs Water

This is one of those foam roofing myths we do not understand. Think of spray foam roofing as a raincoat for your commercial roof—one that repels water instead of absorbing it. Once cured, SPF roofing materials repel water and prevent it from soaking in—even in areas where it may appear to pond.

Just like with any roofing system, proper maintenance will keep your roof protecting your building for years to come. Even with a water-resistant roofing system like SPF, it is essential to inspect your roof at least yearly. Call us at CD Beiler Commercial Roofing to schedule a free, on-site roofing inspection if you have any concerns about your current roofing system.

8. Foam Roofing is a Terrible Insulator

After debunking several other foam roofing myths, it is clear that foam applications and roofing materials are an excellent insulator. Not only does this roofing system keep the heat in your building during the winter, but it also reflects UV rays during the summer to keep your roof up to 80 degrees cooler.

9. Spray Foam Roofs are Soft

Once cured, spray foam roofing hardens and does not feel like a “foam mattress” as many foam roofing myths try to claim. This roofing material is durable and tough enough to withstand almost any weather, and you can easily walk on it for inspections and repairs.

If you ever notice any soft spots or damaged areas, calling a professional roofer to assess the situation may save you money in the future.
