How to find roofing squares.

If this distance measures 4 inches you have a 4 in 12 pitch. First use your measuring tape to measure 12 inches on your large level and make a mark at the 12 inch line. Next place your ladder against your house at the gable end. Do the same from one gable end to the other to determine parallel and also measure the roof diagonally.

The easiest way to measure this section is to divide it up into three different sections. The answer is the number of roofing squares for the roof. Climb to the top of your roof. S1 s2 and s3.

After that place your level against the gable trim and flat against the side of the house. As you can see s1 and s3 are the same size but you still need to document all measurement points to verify your material calculation accuracy. 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. Since s2 is now a rectangle simple l x w is all that is required.

To determine if a roof is square measure from the eaves to the ridge at several points along the roof to see how parallel they run. Roofs that are out of square can make the slots between shingle tabs look cockeyed. 8 inches and you have an 8 in 12 pitch. Because each 100 square feet of roof is one roofing square divide the total area from step 1 by 100.
