If you are looking for an energy-efficient roofing product, a foam roof may be a great option. A foam roof is usually comprised of sprayed polyurethane foam. The polyurethane is made from a mixture of polyol and isocyanate. As the two components are combined and sprayed onto the roof, they convert from a liquid to a foam solid. Here are some advantages of having a polyurethane foam roof:
A foam roof does not have any seams. Thus, when it rains or snows, no water can leak into roof joints to cause a leak within your home. The foam forms a single unit so that there are no connecting points through which water or moisture can enter. This is especially helpful for roofs that contain roofing accessories, such as sky lights. The foam forms such a complete, watertight seal around the structure that leaks are eliminated.
The seamless nature of a foam roof also prevents air from escaping or from entering the building through the roof. Poyurethane foam has a high R-value, which means that it is highly insulating.
In fact, a foam roof can reduce energy expenditures by 30 percent, which means that the price of the roof may be recovered in about five years from energy savings.
Light in Weight
The weight of a roofing material can be important, especially in areas in which snow or ice accumulates on a roof during the winter months. A roof that is already unusually heavy may collapse under the weight of snow.
A foam roof only weighs about 50 pounds per square. This is only a fraction of the weight of other roofing materials
Little Preparation Needed for Installation
For some roofing materials, the existing roof must be removed before the new roof can be applied. However, with a foam roof, the foam can be sprayed directly on top of the existing roof structure.
In addition, since the foam is sprayed onto the roof surface, no special preparations or adjustments are needed even if the roof has an irregular shape or unusual contours.
A foam roof does not require a high degree of maintenance. In addition, the longevity of the roof is indefinite. If a portion of the roof is damaged by a falling object, it can be re-sprayed to repair the surface.
