In warm weather climates like Arizona’s, insulation can be a big help in keeping a home comfortable. The most likely place a homeowner will find a need for insulation is in their roof. After all, a majority of a house’s living space is above ground and enclosed by walls made from sheetrock and studs which are filled with cavity insulation — but, even this type of construction is incomplete without roofing materials that also provide structural support as well as insulation. At Express Roofing, our team of professional roofers complete first-class work for homeowners across the Phoenix area of the east valley. As your full-service roofing company, we meet homes’ insulation demands with roofing types such as Spray Polyurethane Foam (SPF). Here is a breakdown of why insulation is so important to your roof.
