Not every roof (or every part of a roof) qualifies for shingles. Asphalt shingles are not manufactured to tolerate standing water. They require a pitch that allows the water to sheet off the roof to the gutters. The standard is that your roof must have a pitch of at least 2:12 inches. That means that you have to have 2 inches of upward slope to 12 inches of horizontal roof. This allows water to drain off the roof without puddling.
Many of today’s roofs have portions that are considered low slope or flat areas such as over porches or on other architecturally designed areas of the roofing structure. When the area of roof is not seen from the curb or from windows of the home, there are a variety of roofing materials that can be used along with the shingles on the high pitch areas of the home. These include TPO and PVC membranes. These are durable and cost-effective solutions for low slope roofs. When the low slope area is part of the curb appeal of the home, these are great candidates for metal roofing materials.
