Roof Plan

roof

It is the external upper covering of a house or building. It shows the size, shape and the type of materials that should be used in the roofing system.

Gable Roof

has a pitch on two sides but no pitch on the gable ends. This type of roof is used extensively in Philippines "bahay kubo" and raw houses in subdivisions. The pitch or angle of a gable roof varies from the high pitch roofs found on chalet A-frame style buildings to the low pitch roofs found on most ranch homes.

Overhang

is a roof type where the pitch is low and extends on the side of the building perpendicular to the rafters direction. It should provide additional protection from the sun and rain.

Hip Roof

is a roof where all four sides of the roof slope downwards from the peak. Hip roofs are very popular in warm climates. They are commonly used in Regency and French Provincial homes.

Flat Roof

is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof are used to create a low silhouette on modern homes. Slightly heavier rafters are needed for flat roofs. Built-up asphalt construction is often used on flat roofs.

roof plan

is a scaled drawing or diagram of a proposed roof development containing dimensions of the entire roof structure, including shape, size, design and placement of all materials, ventilation, drainage, slopes, valleys and more.

overhanging eave

is the edge of a roof, protruding outwards, beyond the side of the building generally to provide weather protection.
