Tips For Calculating Roof Area So You’ll Know How Many Bundles Per Square You’ll Need For Roof Area Coverage.

The most correct way to calculate what number bundles of shingles you’ll need are to get up on the roof and measure each roof plane. If all the roof planes are rectangles, you just got to multiply the length times the dimension of every plane to get the sq. footage; then you’ll add up the square footage of each plane. several times, the roof is also too steep to run on without safety equipment, therefore you will need to do the estimate from the bottom. If this can be the case, measure the length of the building at the ground level and estimate any rake-edge overhangs. Next, from a ladder, use a stiff, wide blade measurement tape to measure from the edge of the eaves to the ridge.
