Sloped Roofs are high or low pitched, single structures or assimilation of many sizes and pitches. Sloped roofs, make the skyline vibrant at any time of the day, and during evenings in illuminated city scapes. Sloped Roofs are heavy at the bottom, and so are gravity compliant. Sloped roofs seem stable even if project out of the nominal (structural) foot print of the buildings. In modern day scenario of Air Travel, sloped roofs make a fascinating urban scape.
As a building element this are not tied by creation of functional spaces, placement of openings and literally sky is the limit to fly-out. The roofs are essentially external architectural statements and so variety of surface textures through materials and form-treatments are possible.
Sloped roofs are of many different varieties. The simplest is the lean-to, or shed, which has slope in only one direction. A roof with two slopes that form an “A” or triangle is called a gable or pitched roof
A hipped roof is a like gable roof but has slopes on all four sides.
The gambrel roof is a type of gable roof with two pitches on two sides, the upper being less steep than the lower.
The mansard roof is a hipped gambrel roof, with double pitches on all sides.
A pyramidal hipped roof, also known as a pavilion roof, is hipped equally at all corners and the hips meet at a single peak, but the common form of hip roof is above a rectangular structure, and so there would be a roof ridge meeting two hips at either end.
A variant is the half-hipped or jerkin head roof, which has gable ends truncated by the eaves of a small hip end (or jerkin head) that descends a short distance from the roof ridge. On an irregularly shaped structure, there may be more than four hips, which then may alternate with valleys, to form a hip-and-valley roof.
