Residential low-slope roofing is a common choice for many homeowners, and it can generally be divided into two broad categories. The first category includes larger flat-roofed applications, such as those found in residential condominium complexes, row homes, and townhouses. The second category of residential low-slope roofing includes smaller applications, like transitions from the main home to porches or garages. In these situations, the roof's slope changes dramatically from steep to low slope on the same structure.
