How do I measure my roof for shingles?

To estimate how many shingles you’ll need, first estimate the total square footage of your roof’s surface. To do this, measure the length and width of each plane on the roof, including dormers. Then, multiply length x width to get the square footage of each plane.

How do you calculate shingles for a roof?

This means you would need 24 squares of shingles to cover that roof.
