Spike's Calculators

Calculate the area of a Hip Roof using metric measurements online.

The square metres of a Hip roof area are identical to the square metres of a Gable roof of the same size. The only difference in this calculation to the one for a Gable roof area is the amount of the Ridge. The top ridge will be shorter than the one of the Gable roof, but the four hips will add to the Ridge length.
