Mansard Roof Calculator
Calculate your mansard roof requirements with our comprehensive calculator. Estimate roof area, materials needed, and construction costs based on your building dimensions.
Step 1: Roof Dimensions
Understanding Mansard Roofs
A mansard roof has two slopes on each of its four sides, with the lower slope steeper than the upper. This design maximizes usable space in the attic or top floor, often used in French architecture.
Step 2: Materials & Cost
About Roofing Costs
Roofing costs vary based on material quality, roof complexity, location, and labor rates. Mansard roofs typically cost more than standard roofs due to their complex design and additional materials required.

Mansard Roof Area Formula
Total Area = (Lower Slope Area × 2) + (Upper Slope Area × 2)
Lower slope area = building length × lower roof height × slope factor. Upper slope area = building length × upper roof height × slope factor. The slope factor accounts for the roof pitch and is calculated as 1 / cos(pitch angle).
