While it is possible to estimate the amount of necessary materials using only the total roof area measurement as can be seen from the table depending how large the pitch of the roof the actual area of the roof can differ by up to 2 236 from the measured total area at a pitch of 24 12. As such while it can be cumbersome measuring the area and pitch of each part of the roof and multiplying by the corresponding correction factor will result in the most accurate estimate of necessary. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.

That gives you 5 590 square feet which is the actual area of the surface of the roof. Next place your ladder against your house at the gable end. Place the other end of the level at the peak of the roof and hold it level. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.

You can also zoom the map and click on the starting point of the roof you wish to select. The number you get will be an accurate estimate of how much area you have to cover for your roofing project.

This is expressed in terms of how many inches the roof rises for every foot of horizontal distance. This applies to lengths as well as areas. The answer is the number of roofing squares for the roof. As you add points the area will be updated below and converted into acres square feet meter kilometers and miles.

Convert the area to roofing squares. First multiply the length by the width. To calculate the area of your roof first you ll need to calculate the pitch of it. Mark a level 12 inches from one end.

Multiply the area by the pitch multiplier to get the roof s square footage. If this distance measures 4 inches you have a 4 in 12 pitch. Then take the product of these two dimensions and multiply it by your pitch multiplier. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof.
