I just received a re-roofing quote from a contractor that says that the job
will require 17 squares. The property is 950sqft under roof and the pitch is
4.5/12.

Is it possible that a 950sqft house can have a 1,700sqft roof? I'd measure
it myself but it's a 500 mile trip to the house.

Given that pitch, 17 square for the roof seems VERY high for a 950 sqft
house.

Check out this calculator. The results are rough -- no accounting for
type (hip, gable, etc) of roof -- but it won't be wildly off:

bought the materials....(about 1500. bucks)

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.
