Pitch is the height of the roof. Generally, all roofs have pitch. Even a flat roof is provided with a minimal slope to keep water from accumulating and adding to the roof load. However, there is a certain category of roof types that has a relatively high pitch called “pitched roof.” Gable-type and heap roofs are considered under this category. A roofer must understand the importance of pitch in a roof to come up with efficient designs.
Gable-type and heap roofs have sloped surfaces meeting at a single edge called the ridge. From the ridge down to the base of the joists is the maximum pitch. Nevertheless, pitch may also pertain to the level of inclination of the faces of the roofing. Heap roof is almost similar with a gable-type roof, except that it has more inclined faces, usually twice as many. These faces have similar maximum pitch.
Pitch performs several vital functions. One of these is to keep water from accumulating on the surface of the roof and from posing threats of leaks. While the faces are inclined, rainwater is expected to slide through immediately towards the gutters and downspouts. Many roofing companies in tropical cities like Miami provide adequate pitch for roofing to avoid spills from the gutter that might damage the adjacent walls and windows.
A roofing company miami base the pitch a roof based on several factors, including snow formation management, ventilation support, and adding space in a structure. As snow falls on the roof, it accumulates and hardens easily, causing the roof to sag or, in worse cases, break. Snow load causes most roofing damage. By adding the pitch, snow can slide even at a minimum weight.
Pitch also has a part in maintaining good ventilation in the house. It creates a gap between direct sunlight hitting the roof surface and the internal structure of the house. Most structures with low-pitched roofs tend to heat up more easily than those with high-pitched roofs. A roofing company miami recommends putting up improvised ventilation as support to low-pitched roof.
Most houses with high-pitched roof have attics available for storage or as a room. With adequate height, the space between the ridge and the ceiling can be used for these purposes. Households usually hire a roofing company miami to improve the thickness of the roof layers and the ceiling to make a strong attic inside the pitch.
