Kent Roofing: Article About What Good Is A Gabled Roof?
The term, gable, refers to the triangular part of a wall sandwiched between two adjoining slopes on a roof. Compare this to a hipped roof, which has no gables. Instead, all four slopes join at a common point at the apex of the roof. Not all gables are triangular. A gambrel roof, for example, has two slopes, a lower steep slope and an upper shallower slope, resulting in a wall shaped like an irregular heptagon, i.e., with seven sides of different lengths and angles.
In general, the slope of a gabled roof is between 20 and 45 degrees, although both shallower and steeper roofs are possible.
A gabled roof therefore obviously looks different from a hipped roof but also has significant functional differences. Gabled roofs are not popular in areas that are subject to hurricanes. This is because the leeward side is exposed to upward lift; the shallower the pitch of the roof, the more lift will be created. Fortunately, Kent roofing is not subject to hurricane force winds.
The main advantage of a gabled roof is cost. It is much easier to build than a hipped roof, and the overall cost is lower in both time and materials. Also, gabled roofs are the more popular of the two fundamental roof styles. Consequently, there are more roofers, more competition and lower prices.

The purpose of a gabled roof, which has a steeper pitch than its hipped counterpart, is to facilitate runoff of rain and snow. Snow can damage a roof, sometimes even to the point of caving in. Unlike hurricanes, snow is something that may be found harassing a roof in Washington state.
Because a hipped roof has more seams than a gabled roof (four versus two), a hipped roof has more potential to develop leaks. It is also easier to incorporate a gabled roof into other structures. Gabled roofs also allow for more attic space than a hipped roof.
There is another, somewhat cheeky, advantage to a gabled roof. Some communities have very strict building codes in which buildings with extra stories are banned. With a gabled roof, the builder can sneak in an extra half-story without arousing the wrath of the local authorities.
When designing a gabled house, the designer has the option of placing the ridge of the roof parallel to the street and the gables at the side of the house. This arrangement was popular in Gothic Germany and Renaissance-era France. Gablefront houses, where the ridge of the roof runs perpendicular to the street, were popular in the 18th and early 20th century.
