How we calculate
The math, out in the open
Roofers price by the square — 100 square feet of roof. Here’s how we get from your home size to squares and dollars.
- 01
Footprint
Home size ÷ stories. A 2,000 sq ft two-story sits on about 1,000 sq ft.
- 02
Overhangs
× 1.15 for eaves and rakes that stick out past the walls.
- 03
Pitch
× the pitch factor: 1.05 at 4/12, 1.12 at 6/12, 1.20 at 8/12, 1.41 at 12/12.
- 04
Waste
× 1.10 for cutting, starter strip and ridge caps. ÷ 100 = squares.
- 05
Price
Squares × $475–$650 for shingle or $1,050–$1,450 for metal. Steep roofs (8/12+) add 5–12% for harness work.

FAQ
About the numbers
How accurate is the calculator?
For a typical roof it lands within about 10–15% of our final price. The difference comes from things only an inspection shows: extra layers, rotten decking, skylights, a complex roof with many valleys.
Why do you show prices when other roofers don’t?
Because you’ll find out anyway, and a number you can plan around is more useful than a sales visit. The fixed price on your estimate is the one you pay.
Does the price include tear-off and disposal?
Yes — tear-off of one layer, dumpster, disposal, permit, underlayment, flashing, ridge vent and clean-up. Extra layers and decking are priced below.
What about insurance claims?
If storm damage is covered, your insurer pays the replacement cost and you pay your deductible. See how a claim works.
