A steeply sloped roof creates extra space in the structure. All of the space below the roof fills with air, changing how heating and cooling systems work. A low slope roof limits this extra air and makes a structure easier to keep comfortable throughout the seasons. Depending on the amount of slope, limited attic space still fits between the ceiling and the roof for storage or ductwork.
Since water and ice sit on the surface of a low slope roof much longer than on one with a high pitch, the roofing materials receive more wear, which increases the maintenance requirements and associated costs over the lifespan of the structure. If rolled roofing materials are used, they will need annual cleaning and resealing. However, low slope roofs make maintenance easier because walking around on them is easier. The risk of slipping and falling off is much lower than on a steep roof.
A low slope or flat roof requires less material to build, lowering the overall installation cost . Even if you choose a roofing material more expensive than the shingles that steep roofs use, the lower labor costs for low slope roofs offset the cost. The structure is easier to build because supports are installed from the sides of the building without workers having to lift up large trusses. Rolling out and sealing the roofing materials also takes less time than installing individual shingles.
