I dusted off some brain cells I haven't used in a while and tried to
calculate based on the geometry
I can remember......close, but my calc. was under 1,000. Even with a 2'
overhang and 10% waste,
it comes to around 12 squares. If the roofer is known and reputable,
nothing wrong with questioning
the estimate. Could be something as simple as a typo. If he tries to
explain it away, then another
roofer is in order.
