Have you heard about foam roofing and its outstanding insulation properties before? If you haven’t yet, this is the perfect time to do so as it might be exactly what you need to add more barrier between you and extreme temperatures.
What is it?
Polyurethane foam is a liquid that is applied over existing roofs to create and expand into a foam layer. It is incredibly helpful for asphalt roofing shingles or metal panel roofs to create a layer of insulation and make your home more energy efficient. There are quite a few roof shingle types that can be installed with foam roofing. Source: Modernize
Different types
Cool roof coatings fall under the class of elastomeric coatings. These coatings protect the foam underneath and provide a painting surface. This creates an additional waterproof membrane that reduces heat infiltration on the roof. A cool roof coating may require several weeks of drying for additional layers of foam. The elastomeric coating also reduces the UV radiation from the sun that can cause foam to oxidize over time. All of these coatings can be applied at the same time as well.
Installation of a foam roof will require substrate preparation, coating and sealing. A foam roof cannot be applied directly without conditioning the substrate below. A clean, dry surface is prepared for contact, a process that includes the removal of any existing roofing material. The entire surface is primed with an adherence polymer to increase the adhesion of the foam product to the roof deck. This priming also prevents overspray from foam during the curing phase.

Advantages and disadvantages
Spray foam roofing systems have many advantages, such as being more energy-efficient than conventional asphalt or metal panel roofs and creating less of a carbon footprint. However, we should also take into account some drawbacks when installing a spray foam roof on your home or property.
