Roofing square estimate help needed

[jrfan]

Could any of the roofers here help me figure out how many squares of asphalt shingles it would take to cover the roof in the diagram.

How many sq. ft under roof and pitch?

[jrfan]

5/12 2700 sq ft floor space.

[JP Weld]

53sq which includes a 15% waste factor.

Ok. Thanks. They are wanting to charge me for 53 sq to tear off. But I figured it up at 45 sq. Is that correct?

Tear off is 46sq.

They also shouldn’t be charging you waste on felt. If they’re using Xactimate, which most do to write estimates, waste is built in.
