Pyramid and pavilion roof takeoff

Pyramid Roof Calculator

Estimate a square pyramid roof or pavilion roof from base size, overhang, pitch, waste, and material cost. Use it when pyramid roof calculator searches need area, hip length, and roof squares without structural sizing claims.

Pyramid roof geometry is not structural design

This estimates roof surface area and simple hip length for a square equal-pitch pyramid roof. Rafters, hips, ties, uplift, snow and wind loads, ventilation, sheathing, fasteners, and local code must be verified before building.

Pyramid roof formula

Run = base size ÷ 2 + overhang

Rise = run × pitch ÷ 12

Sloped plane height = sqrt(run² + rise²)

Roof area = 4 × 0.5 × roof edge × sloped plane height × (1 + waste %)

Sample takeoff

A 24 ft square pavilion roof at 6/12 pitch with 1 ft overhang and 10% waste is about 831 ft², or 8.3 roof squares, with 19.5 ft hip rafters.A 7.2 m square pavilion roof at 6/12 pitch with 0.3 m overhang and 10% waste is about 74.8 m², with 5.9 m hip rafters.

Pyramid Roof Calculator FAQ

How do I calculate a pyramid roof area?+

Find the run from the base center to the eave, calculate rise from pitch, find the sloped plane height, then multiply one triangular roof plane by four and add waste.Find the run from the base center to the eave, calculate rise from pitch, find the sloped plane height, then multiply one triangular roof plane by four and add waste.

Is a pyramid roof the same as a hip roof?+

A square pyramid roof is a hip roof with four equal triangular roof planes meeting at one top point. Rectangular hip roofs and irregular hips need separate layout checks.A square pyramid roof is a hip roof with four equal triangular roof planes meeting at one top point. Rectangular hip roofs and irregular hips need separate layout checks.

Can this size roof rafters or hips?+

No. It gives geometry and material takeoff numbers only. Use span tables, engineered drawings, product data, and local code for member sizing.No. It gives geometry and material takeoff numbers only. Use span tables, engineered drawings, product data, and local code for member sizing.
