Roof Foam

Why it is a bad idea to use foam on your roof!

If you have researched different types of insulations for your home, you probably have heard of Spray Polyurethane Foam Roofing, or even considered using it to insulate your home. It is a type of insulation that has gained popularity in recent years thanks to reality shows. Indeed, there are a few good things about spray foam insulation: it can be easily installed by spraying the mixture onto a roof through a hose and there is no need to remove any previous roofing materials.

It can also reduce energy costs and consumption by keeping the heat (or cool air) within the house. However, if you learn more about spray polyurethane foam roofing, you would know why it is not a great choice for insulating your home.

The polyurethane foam coating insulates and protects the roof, while the layer of silicone prevents the foam from deteriorating due to weathering. The installation of SPF’s material is a particularly demanding process in which precise mixing and layering are required, as well as regulation of the exact temperatures of the chemicals. If done incorrectly, it could lead to serious problems such as cracking, off-gas.

Spray foam insulation‘s key ingredients could cause serious health problems upon contact. Exposures to the main chemicals of SPF, such as isocyanates, “in vapors, aerosols, and dust during and after installation can cause asthma, sensitization, lung damage, other respiratory and breathing problems, and skin and eye irritation,” according to the United States Environmental Protection Agency.

This makes it imperative for residents to stay out of the house during and after spraying. Furthermore, if installed improperly, spray foam insulation can even result in a strong and unpleasant smell in homes. This effect of off-gassing (the spread of chemicals through the air) can only be cleared out by removing the foam, which would involve taking down the walls and roof.

Off-gassing is not the only negative consequence that comes out of spray polyurethane foam roofing. Many additional problems can be caused by faulty SPF installations. The contractor has to consider various variables in the spraying process, including the moisture level, wind directions, and temperature. They would also need to take precautions for overspray, which is when the foam is carried away by the wind or floats over the roof’s edges, and lands in unintended places.
Protective shields must be put along the edges of the roof and covers should be placed on nearby cars as well. Neglecting any of these aspects would lead to complications that would be costly and troublesome to deal with.

Industrial standards for spray polyurethane foam roofing are lacking, which means it would be difficult to find companies who would be willing to remove it if contractors did not address the problems. In addition to the absence of protocols, the durability of spray foam insulation also makes the removal process troublesome. One would either have to remove the roof entirely or manually scrape out the foam, which could lead to overspray.
With all this being said, Spray Polyurethane Foam Roofing is not a great choice for home insulation, due to its tricky installation process and the multiple potential adverse impacts including health problems, off-gas, and difficulty in removals.
