The type of residences that typically have a flat roof are rowhouses or townhomes, but other homes with additions or porches may have partial flat roofs on those sections of the house. Traditionally, flat roofs have been constructed of tar products, and have been relatively inexpensive. Unfortunately, these roofs wear out and become damaged much more quickly than pitched roofs. Years of weather will weaken the roof surface, causing water to “puddle”. Eventually those areas of the roof will leak, so flat roofs need to be inspected regularly, and repaired or replaced.
The more recent introduction of rubber-based roofing materials, allows flat roofs to last much longer.
