Roof Area Calculators:
For each of the roof types pictured below, L = Horizontal Length, W = Horizontal Width, and H = Vertical Height, all entered in feet. Slope in inches per foot may substituted for H.

Hip roofs can present a problem for height measurement, and the slope method may be substituted in place of height measurement. Since modern architecture has allowed the incidence of mixed slopes in a single structure, the calculator allows for entry of differing slopes for intersecting roofs.

For many roofs, dimensions can be taken from the ground or from a ladder. Be sure that your measurements include any overhang at the eaves. Height can often be measured at the end wall at the center of a gable.

Complex roofs may have numerous repeats of these shapes - perform a separate calculation for each section, then add the results together (on paper) to obtain total roof area. A "salt box" roof with unequal sides may be calculated as two separate shed roof shapes. An "A-Frame" roof is simply a gable with high slope.


GABLE OR HIP ROOF: A gable roof and a hip roof of the same length and slope will have identical areas.  
Enter roof dimensions below for your roof in feet, (or slope as inches rise per foot.)
  • If you enter only L-1, W-1, & H-1, the result will be the area of a single straight gable roof.
  • If you enter all six values, the result will be the actual exposed area of both roofs. You cannot enter values for Area 2 alone.
  • The values calculated for roof 1 and roof 2 are independent. The total will not equal their added values, as the calculator subtracts the hidden area from roof 1 at the intersection, and displays only the actual exposed roof area for the total.
