Formula For Measuring A Hip Roof

The square footage of a hip roof area is identical to the square footage of a gable roof of the same size.

Formula for measuring a hip roof.

Doing so will give you the total square footage of your roof. For many people being able to get the right kind of hip roof calculator is very important as knowing how to measure a hip roof is going to be vital to making sure that it turns out well. The top ridge will be shorter for a hip roof but the 4 hips will add to the amount of ridge capping needed and because of the angles the amount of waste will be higher than for a similar sized gable roof. The only difference in this calculation to the one for a gable roof area is the amount of the ridge.

Step 5 multiply the total square foot area of the hip roof by 5 percent or 05 for the amount of extra roofing material you ll need to allow for waste due to roofing error or damaged material. The pythagorean theorem allows you to calculate the length of the hip rafter without measuring it directly which requires you to climb onto the roof. Add the combined areas of the 2 longer faces with those of the 2 shorter faces. If you are trying to undertake this all yourself then you should really be looking for the most effective way of working out things like the hip roof square.

A hip roof s square footage is equal to that of a gable roof with the same dimensions. Calculate the amount of asphalt or fiberglass shingles needed to cover a hip roof. If you re trying to work out the total area of the roof of a square building simply multiply the area of one of the identical faces by 4. Here you can calculate hip roof parameters by hip raise and.

The difference is in the amount of ridge capping you need and the amount you will waste. Add the areas of the faces of the hip roof to find the total area of the hip roof in square feet. The top ridge will be shorter than the one of the gable roof but the four hips will add to the ridge length. This theorem states that the length of a right triangle s hypotenuse is equal to the square root of the sum of the squares of the lengths of the triangle s other two sides.
