Definitions vary on when a roof is considered pitched. In degrees, 10° (2 in 12 or 1 in 6) is considered by at least one reference a minimum. [5] In trigonometric expression, exact roof slope in degrees is given by the arctangent. For example: arctan(3 ⁄ 12) = 14.0°. Framing carpenters cut rafters on an angle to "pitch" a

Arched roof, bow roof, [11] Gothic, Gothic arch, and ship's bottom roof. Historically also called a compass roof. [12] [13] Circular Bell roof (bell-shaped, ogee, Philibert de l'Orme roof): A bell-shaped roof. Compare with bell-cast eaves. Domed; Onion dome or rather an imperial roof; Bochka roof; Conical roof or cone roof; Hyperbolic Saddle
A roof pitch of at least 50 degrees allows precipitation to travel quickly down slope so that it runs off the roof before it can penetrate the structure. Thatch is also a natural insulator, and air pockets within straw thatch insulate a building in both warm and cold weather.
A 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°. [1] 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. Flat roofs, or "low ...

Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
