How the stone coated steel roofing cost estimate works
Roofers price by the square — 100 sq ft of roof surface. The calculator converts your home's footprint into roof area using a pitch factor (a steeper roof has more surface than the floor beneath it) plus about 10% for overhangs, then applies Texas installed pricing of roughly $10–$18 per sq ft for stone coated steel.
What moves the price
- Profile: shingle is the most economical; tile and slate profiles take more trim and labor.
- Complexity: valleys, dormers, turrets and skylights add flashing work.
- Tear-off: removing one or two layers of old roofing and hauling it away.
- Install method: foam-set systems for high-wind coastal homes cost more than batten or direct-to-deck.
- Brand: value tiers like Allmet sit at the low end; Tilcor and TEK at the high end.
