Use our free Hip Roof Area Calculator to quickly determine the total surface area of your hip roof. This essential tool helps you estimate the quantity of shingles, underlayment, and other roofing materials needed, ensuring a precise project plan and budget. Input your building's dimensions, eave overhang, and roof pitch for instant results.
Formula:
Roof Area (A) = (L + 2O) × (W + 2O) / cos(Prad)
- A = Total Hip Roof Surface Area
- L = Length of the building footprint
- W = Width of the building footprint
- O = Eave Overhang
- Prad = Roof Pitch (in radians, where Prad = Pdegrees × π / 180)
- cos = Cosine function
