How To Get Squares On Roof

Instead of charging per square foot roofers use this particular measuring tool as a way to streamline their costs and ensure both parties are on the same page.

How to get squares on roof. Step 3 measure between the tongue and blade as the square lays on the rafter. In general the average residential property will have a roof measured between 22 35 squares. To find the squares divide the overall roof area by 100 and then round up. For a roof with 8 12 pitch find 8 inches on the shorter arm of the square the tongue and 12 inches on the longer end the blade.

Calculate each plane separately. Install cedar shingles with two 5 penny. Multiply the length and width of each square or rectangle shaped plane. A square simply refers to a 10 x 10 square of roofing.

The only difference in this calculation to the one for a gable roof area is the amount of the ridge. Refer to figure 1 where diagonals ad and bc af and be are equal.

For square or rectangular roofs you ll only need to record the length and width. The answer is the number of roofing squares for the roof. For example if one roof plane measures 120 feet by 120 feet 120 x 120 14 400 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.
