My roof is 60' x 30' with a 15 degree pitch, how much
appx. would that cost? Asphalt shingles, three tab, around
25 year. I've been asking questions at hardware stores.

What kind of terms can I expect from a roofer when I get a new
roof?

I could pay $1200.00 and make payments of $200.00 per month.
Would a contractor be likely to do that?

The wind and rain really messed things up in this area in the
last month.
