Different roofing materials and accessories are needed to properly install a roof based on its shape and the complexities it may have, such as a patio that ties into the roof or a chimney. There are two main categories of roof: steep slope and low slope. Most residential roofs are steep slope, while low-slope roofs are typically used on commercial buildings, sheds and garage transitions.
Below are the basic types of roof structures:
A hip roof slopes back from all four sides. Hip roofs don't have valleys where leaves can collect and sometimes cause complications
A gable roof is something a child might draw. This type of roof has two sloping sides that join together at the top to form a ridge, thus creating end walls and a triangular extension, which is known as a gable.
Each sloping roof section of a gambrel roof is divided into two parts. The first is the portion close to the ridge that is relatively flat. The second part, which is closer to the eaves, drops down steeply. This style of roof creates maximum use of space under the roof.
Each sloping section of a mansard roof is divided in two. The section of the roof closest to the walls rises steeply to create maximum space under the roof. The roof then continues at a milder pitch towards the center.
Flat roofs, also known as low-slope roofs, are typically found on commercial buildings. However, these roofs can also be on porch and garage transitions.
A shed roof slants in just one direction. These roofs are easy to build since the rafters are all identical.
A dormer projects out from the rest of the roof and typically have windows. Dormers are added for beauty and style and also add space and light to the inside of the house.
Turret roofs, also known as a conical or radius roofs, are a small, round or polygonal tower topped with a conical or hipped roof.
A skillion roof is one single flat surface and differs from a standard flat roof due to the steeper and more noticeable pitch.
This unique roof is a gable roof with the ends of the gables clipped to resemble a hip roof. By clipping the ends, the peak of the gable roof is streamlined, which reduces the stress caused by wind as well as diminishes the potential for wind damage.
