Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements.

How do you measure a roof of a building.

For example what we need on the picture of the roofs below are measurements of all the blue or red lines. Outline the roof at the points that are on the same level or elevation to ensure that you re getting an accurate calculation of your roofing measurements. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. 3 multiply the amount of overhang by two to include the opposite side of the building.

The length l times the height h of a triangle is twice its area a2. Calculating an area of a triangle when estimating a roof. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area.

Roughly draw out your roof on a piece of paper. 8 inches and you have an 8 in 12 pitch. 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. Pitch measurement method 1.

Remember it doesn t have to be to scale or look pretty. It does have to contain all the straight lines of your roof and an accurate measurement of those lines. Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof. Outside of the u s a degree angle is typically used.

So if you divide your answer of a product of length times height by two you will get the area of a triangle. Thus in a simple style house you ll only have to click on the corners. First measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. 1 roof square 100 square feet.
