How much does a roof replacement cost for a 1,000 sq ft house?
What 1,000 square feet means for the roof
If you mean a 1,000 square foot one-story house, the roof is larger than the floor: overhangs add area and the pitch adds more. A moderate 6/12 pitch on that footprint often works out to around 12 to 14 squares, a square being 100 square feet of roof surface. If you mean 1,000 square feet of actual roof surface, that is 10 squares, typical of a small cottage, a large detached garage, or a two-story home with a compact footprint.
Why the per-foot price is higher on small roofs
- Fixed costs: permit fees, the dumpster, delivery, and setup cost about the same for 10 squares as for 25.
- Details do not scale down: a small house still has a chimney, pipe boots, vents, and edges that need the same flashing work.
- Waste: short runs and cut-up shapes waste a larger share of each bundle.
Do not let the size tempt a shortcut
On small homes, overlaying a second layer of shingles can look like an easy way to save. It usually is not: the old roof hides decking problems, adds weight, shortens the new shingles' life in the Georgia heat, and can complicate warranties and insurance. Read roofing over existing shingles before agreeing to one.
