Roofer has given me a bid for residential roof replacement in Austin, TX at
$155 per square, as follows:

$ 20 - tear out old shingles, adjuster's estimate
$ 101 - replace 3-tab asphalt shingles, adjuster's estimate
$ 12 - steep slope allowance, adjuster's estimate
$ 22 - upgrade from 3-tab asphalt to Atlas Pinnacle 35-year shingles
-------
$ 155 - Total per square

46.33 squares total will be replaced.

Price includes Cobra II ridge vents, new felt, inspect and replace decking
as required (4 pieces free), replace auto caulks/ lead risers as needed,
nail new shingles, protect plants, nail pickup, haul-off.

There is some rusty flashing around upstairs room, he didn't mention that.

Does this seem like a good bid to you? Too high?

Are the Atlas Pinnacle shingles good?
