Hip roof is a roof with a sharp edge or edges from the ridge to the eaves where the two sides meet. Here is the online hip roof area calculator which helps you calculate the hip roof parameters such as roof rise, common and hip rafters length and roof area based on width, height of roof base and the roof pitch (identical for all sides). Calculating the dimensions of the hip roof rise and area would be very easy and time saving using this calculator.

Calculating the dimensions of the hip roof rise and area would be very easy and time saving using this calculator.
If the length and width of the Roof base is 100m and 70m and roof pitch is 45 degrees
Roof Rise (H) = (B x tan α) / 2
= (70 x tan 45) / 2
= 35m
Common Rafters (R) = B / (2 x cos α)
= 70 / (2 x cos 45)
= 49.4975m
Hip Rafters = √(H2 +(B2 / 2))
= √(352 + (702 / 2))
= 60.6218m
Hip Roof Area = 2 x R x Roof Base Length
= 2 x 60.6218 x 100
= 9899.494m2
