What Every Homeowner Should Know About Closed-Cell Spray Foam Roofing

Keeping Your Roof In Decent Shape

After listening to a few friends of mine complain about the cost of replacing their roof, I realized that I should make sure that my own roof was in decent shape. I climbed up on a ladder to see if I could see the shingles, and things weren't looking very pretty. Some patches of shingles were missing entirely, while others looked badly damaged. Fortunately, I caught the damage early enough that experts could patch up the issues. However, since roofing damage isn't always obvious, I decided to put up this website so that others can spot trouble of their own.

What Every Homeowner Should Know About Closed-Cell Spray Foam Roofing

If you are in need of a new roof on your home, you should definitely consider using spray foam roofing. Here is what you need to know using closed-cell spray foam before you decide to use it for residential roofing

Foam Is Applied As A Liquid

What makes spray foam roofing so unique is how it is applied. The foam materials come as liquids that are stored in canisters and then combined to create the spray foam material. After it is applied to the roof's surface, the foam expands and forms the solid foam material that you are familiar with. Foam is not applied in pre-manufactured sections that are sealed together, since the entire material creates one continuous piece of foam when applied. 

Foam Provides Structural Strength

Since spray foam roofing material dries as a solid piece, it also helps provide structural strength to your roof. This can help the roof become more stable after heavy snow falls and after other weather events that can put pressure on your roof. 

Foam Creates An Air Barrier

The solid construction of foam will also create a great air barrier that helps your home in several ways. When a strong wind blows over your home, the air is not going to find a way in through places where the roof isn't sealed well. In the same regard, air generated by your HVAC system is not going to find a way out through the roof. This helps your home become more energy efficient than it would be with other roofing materials. 

Foam Comes In Multiple Varieties 

You should be aware that there is an alternative form of spray foam insulation known as open-cell spray foam. The main differences with this other version is that the material is spongy and less dense than closed-cell insulation. Open-cell insulation does not create an air barrier and doesn't provide structural strength to a roof. This limits the climate regions where you can install the material, making it a choice that is not as ideal.

Are you still on the fence about whether or not you should use spray foam roofing for your home? Reach out to a spray foam roofing contractor for their assistance. They'll evaluate your home to let you know if spray foam will be a good fit, and then provide you with an estimate cost for the installation. If you decide to move forward with spray foam, you can then schedule your installation when you are ready.
