Building owners are well aware that if there is a leak, even a small one, it needs to be taken care of immediately to avoid more significant and costly issues down the road. You don't want to cut corners when it comes to your commercial roofing system.
So, what happens when you have a faulty spray foam roof installation? Maybe you noticed it has cost you more and more in repairs lately, even though this roofing type is supposed to provide you with watertight protection.
What Is Spray Foam?
Spray foam is supposed to be a watertight roofing system because it is seamless. When it is properly installed on your commercial roof, it can prevent leaks. It typically comes in 55-gallon drums and is then spray applied to the roof. Unlike other roofing materials, since it is sprayed, you cannot see the final product until it is done.
This may cause a building owner to ask a few questions like how do you know if it was installed correctly? What if there was some kind of error during the application? Is there a warranty if repairs are needed following the application?
Proper Application of a Spray Foam Roof
It helps to understand what the proper application of a spray foam roof looks like. When properly applied, spray foam looks smooth. There should be no blistering, discoloration, or areas where the coating looks too thin. The coating is often a gray color as well. If you see any yellow areas on your roof, then this could be a sign that the spray foam installation was not successful.
A Bad Application
Sometimes a spray foam roof looks good when it is first completed, but it can look blistered as the water gets trapped in the insulation. Over time, that water gets trapped, and when enough pressure builds up the blister forms.
When you see yellow, that means that not enough spray foam was used, or the coating has begun to wear away because of its age and the roof's condition.
Spray Foam Installation Process
Before spray foam is applied, there needs to be none installed over any saturated areas on the roof. You don't want any water getting trapped. These areas are easily identified with a simple walk-through inspection. Next, the existing roof needs to be cleaned and dried. This allows the spray foam to better adhere, cure, and perform as it should when applied.
Now the spray foam is applied. It is typically applied in thicknesses of around 1.5 inches to 2.5 inches, but this all depends on your commercial roof's slope and the R-value you want as a building owner.
Once installed, there is a 72-hour window in which a protective coating needs to be applied.
