As with any product, when poorly or incorrectly installed, the roofing system just doesn’t bring the same benefits. That being said, let’s take a look at the Sprayed polyurethane foam roofing problems, and what can be done to prevent them…
Limited Installation Window
Polyurethane foam can be sprayed only during specific weather conditions. There is a narrow range of outdoor temperatures and humidity that allow for installation of the foam. When you try and push the installation window, you can negatively impact the roof’s integrity.
The smallest trace amounts of surface moisture on the substrate results in failure, and foam will not adhere correctly. The optimal climate is warm and dry with no wind. This means you are in the mercy of Mother Nature to get your roof installed.
However, the problem can be easily solved by contacting your contractor early.
Contact the company before the roofing season, and schedule your installation on time. This way, you will have plenty of time to reschedule if the weather season changes.
Spray Foam Longevity: Fact Or Fiction?
One of the many myths and sprayed polyurethane foam roofing problems is that people believe it does not last for long. Well, that cannot be further from the truth.
The solution is reapplying elastomeric roof coatings at strategic intervals on the top of the sprayed polyurethane foam roofing. When you do this, your roof will last up to 50 years. Even better, if you find high-quality elastomeric roof coatings, you will need to apply them just once to strengthen the roof.
It is only natural that the wind can carry the spray from the roof to other surfaces in the vicinity. Yes, sprayed polyurethane roofing can be messy. But that is why you want minimal wind during installation. It is not a health concern, but it is a concern for the surrounding surfaces and property.
The solution is to discuss this matter with your contractor, and make sure they prevent overspray. Also, make sure to note that if overspray happens, your contractor will be the one to cover any cleanup costs, should they occur.
