If you're tired of your old roof and its need for frequent repairs and the high risk of roof leaks, then switching to a foam roof could give you peace of mind that your building is protected from rain as best as possible. Here are some things to know about a spray foam roofing system and how it's installed.
1. Important Advantages of a Spray Foam Roof
Spray foam is unique in the way it's installed and the way it works to protect your building. The foam goes on as a liquid spray that spreads and expands as it foams and hardens. Before the foam gets hard, it can fill cracks and gaps in the roof to eliminate leaky areas. The roofing also has no seams that can leak since the foam is like a coating that forms a single continuous barrier.
Another advantage of spray foam roofing is that the roofer controls the thickness of the foam. That makes it possible to control the slope of the roof so ponding is eliminated and roof drainage is improved.
Spray foam is durable, so the material isn't easily damaged by walking on it. However, if the foam is punctured, it may not leak unless the damage goes all the way through. A foam roof is easy to repair if it's ever necessary by filling in holes and cracks.
2. Things to Know About the Installation Process
Spray foam roofing can often be installed over an existing old roof. However, the old roof can't have moisture damage because it has to be completely dry before spray foam can be applied. As long as the old roof doesn't have water damage, the roofer can clean it by sweeping or blowing off debris, and then the roof is ready for spray foam.
The weather conditions are important when it comes to putting on a foam roof. The roofer may not attempt the process when it's windy or when rain is expected, so your original schedule may need to be adjusted to accommodate changes in the weather. The foam roofing system installation process looks a lot like spray painting the roof. The foam is applied to the correct thickness for the best protection and drainage. Then, a topcoat is applied that protects the hard foam from UV rays and weather exposure.
A spray foam roof goes on fairly fast, and since you don't need to tear off your old roof, the process shouldn't disturb your customers or employees. A foam roof offers excellent protection from rain, and it may even help your power bills since spray foam doubles as insulation. Learn more by contacting foam roofing system installation services.
