Broadly classifying, roofs are of two types, the flat roof, and the pitched roof. The pitched roof is a roof with steep sides as opposed to the leveled surface of a flat roof. The roof pitch is decided by the ratio of the vertical rise of the roof in inches per 12 inches of its horizontal run.
Commercial constructions usually favor flat roofs. Pitched roofs have more aesthetic appeal. Multiple pitches that accommodate multiple gables and dormers give an imperial look to the house. So, residential houses usually sport pitched roofs.
Although a pitched roof is aesthetically satisfying, it is not the only advantage of a pitched roof. It has great practical utility. A pitched roof helps in the uninhibited draining of water. It is very crucial for a roof to stay drainable, as it will avoid water pooling on the roof. The absence of water-pooling reduces the possibility of roof leaks.
When you have a pitched roof, you can have more attic space. When the roof pitch is higher, space in the attic also increases. If it is high enough, you can even convert the attic space into a room. You get a variety of sustainable roofing materials that go with a pitched roof. So, in a way, you can consider a pitched roof environment friendly.
The pitched roofs can be low or high. The low-pitched roof is usually seen on shopping malls, warehouses, and other commercial buildings. The high-pitched roofs are elegant, and so they are preferred by homeowners. Both these styles have their pros and cons.
