A Hip Roof is similar to a basic gable roof, except it has sloped sides (hips) creating triangular ends to the roof and trapezoids faces on the front and back. A basic hip roof has four faces which are all exposed to rain and snow from above and require roofing material.
A Full Hip Roof is defined by the span, length, pitch and overhang, where the angles of the hips are also the same as the pitch.
These calculators compute the area, ridge lengths and materials required for a basic hip roof.
