For example, a shed roof has one roof plane. you’ll simply measure length (A) x width (B): A x B = 120′ x 100′ = 12,000 sq. ft. for the entire square footage of the roof.
Another example may be a gable roof that has two planes. Therefore, you would multiply length (A) x width (B) to get the square footage for every plane. you’ll then add the 2 planes together to derive the entire square footage of the roof:

Be sure to measure the lengths of your rakes and eaves to work out the amount of drip edge needed. Always remember if you’ve got any questions about your supply estimate, ask a roofing contractor in your area. Many are happy to give you a free estimate.

Several studies have shown evidence of carcinogenicity in mice after applications of laboratory-generated asphalt roofing fume condensates were applied.
When neoprene is heated it can discharge dangerous acid into the air. Neoprene is typically safe. Also, the manufacturing of neoprene releases harmful toxins into the air.
