Polyurethane foam has been used as a roofing material for almost 50 years. Made from a combination of isocyanat and polyol, the foam is mixed together in a sprayer and applied to the roof surface as a liquid. The foam then begins to bubble up and expand, reaching into and sealing all the cracks and crevices in the roof. The roofing installation team will then apply a durable outer layer (Elastomeric Coating) to protect the foam from the elements.
Foam roofing benefits:
- Energy Savings
One of the biggest foam roofing benefits is the energy savings. Since the polyurethane material is a highly effective thermal insulator, it can drastically improve air conditioner efficiency in your home. A foam roof can cut your cooling costs by up to 30%. Add that up over the lifespan of your home, and you’re looking at major energy savings!
In terms of upfront costs, foam roofing can be more expensive than shingles, but may be on-par with tile roofing. However, because of the added energy-efficiency, foam roofs can pay for themselves in about 5 years or so.
When you need roofing repair for a tile or shingle roof, you may be looking at a major expense. However, repairs are relatively easy to make to a foam roof: in most cases, a roofer will just need to add more foam to re-coat the foam underlayer. This can also help reduce your long-term costs.
