Things to Know About a Spray Foam on Roof

Spray on foam roof done by a professional

Spray foam is designed to make the building stronger and last longer. It provides insulation to properties and cuts down on energy costs. When people think of certain materials, they want to consider good qualities only. It’s just as important they consider the negative sides that can impact your health, security or finances.

Spray Foam Roofing Pros and Cons

Flammability

Like wood, spray foam is highly flammable and can catch fire under extreme heat. A tiny spark or intense smoke could ignite it. However, the chances are low for this to happen to foam on a roof. The risks increase when the foam is installed indoors.

Sensitivity to UV Light

The intensity of the sun will destroy the foam, causing its disintegration. Most products are coated to protect the roof from UV light exposure. Homeowners who live in sunny climates are encouraged to have their foam coated and re-coated every few years.

Storm Damage

Even weatherproof spray foam is not strong enough to withstand the worst storms. These include hurricanes, thunderstorms, and tornadoes that sustain 100 mph winds and heavy rains with flooding. Foam roofing is strong and durable in normal weather conditions, but under extreme weather, it disintegrates and needs re-installation. So, this material is not suitable in places where severe storms occur often.

Complex Installation

Spray foam is difficult to install except for professionals. It’s not a recommended do-it-yourself installation project, and even making a minor repair can be difficult. The foam is sprayed on as a liquid and then settles as a foam, so since liquids are used, the process is messy if it’s handled improperly. Not making the right measurements also means that the foam is the wrong size and fit.

High Costs

Spray foam insulation costs more than standard insulation with average costs that vary from $1,000 to $5,000. Fiberglass is half of that cost, so an average project costs less than $1,000. Closed-cell spray foam installation is more expensive than the open-cell installation. Although spray foam is more expensive, it provides more insulation along with greater energy efficiency and savings.

Spray foam looks simple on the outside, but it causes major problems for anyone who doesn’t know enough about the material. Some people have messy repairs to deal with after heavy storms, while others have to deal with the high-priced repair bills. There are DIY kits and spray cans available to the public, but for a large foam roofing project, you need the help of professionals.
