Roof Area Calculation

How to Calculate Roof Areas?

Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.)

Finding the Size of the Roof in Squares


A square simply refers to a 10′ x 10′ square of roofing. This is simply 100 square feet of roof. To find the squares, divide the overall roof area by 100 and then round up. For instance, if the roof is 1550 square feet, then it is 16 squares.

Since there are twenty six shingles in a bundle of twenty year shingles (which is fine for starters and edges), divide the result by twenty six. For the number of ridge caps, multiply the length of the hip or ridge by twelve and divide it by five. This house is 1000 square feet. It requires 18 squares of shingles.

Can I get roof measurements from Google Maps? How do you measure a roof without measuring it?
A 200 square foot space is about the size of a one-car garage. In other words, the average car could fit into 200 square foot place with a small amount of wiggle room. Imagine a space smaller than a bedroom for 100 square feet.
