What factors affect the cost of a roof replacement?
When homeowners ask Matt Taylor what a new roof costs, the honest answer is that no two roofs price out the same. The number on a Roofing 101 estimate is built from measurable things about your specific house, not a flat rate pulled out of thin air. Understanding the pieces helps you read any bid you get and spot the ones that leave something out.
The two biggest drivers are size and material. Roofers price by the “square,” which is 100 square feet of roof surface, and a typical central Oklahoma home runs 20 to 35 squares. Material sits on top of that. Asphalt shingle installs at roughly $4.50 to $7.50 per square foot, exposed-fastener metal at $8 to $12, standing-seam metal at $11 to $16, concrete tile at $10 to $16, clay tile at $12 to $20, synthetic slate at $12 to $18, natural slate at $18 to $35, and TPO or flat systems at $7 to $13. That spread is why the material choice matters more than almost anything else on the estimate.
Pitch and complexity come next. A steep roof is slower and riskier to walk, so labor climbs. Every valley, hip, dormer, chimney, skylight, and pipe boot is a spot that has to be cut, flashed, and sealed by hand. A simple gable roof with two planes prices very differently from a cut-up roof with six facets and three chimneys, even at the same square footage. Matt measures all of it before he quotes, because guessing here is how surprise change orders happen.
Then there is what lives under the shingles. If the old roof has to come off in two layers instead of one, that is more tear-off and disposal. If Matt finds rotten decking, soft fascia, or failed flashing once the old roof is up, those boards get replaced so the new roof lands on something solid. Underlayment, ice-and-water shield in valleys, drip edge, ridge vent, and new pipe boots are all part of a roof that actually lasts, and a low bid that skips them is not really cheaper.
A few smaller factors round it out: steep access or a tight lot that limits where the dumpster and material go, permit requirements in your town, and whether the job is tied to an insurance claim after a storm. On a claim, the price is governed by the scope your carrier approves, and Matt works from that scope line by line so nothing legitimate gets left off. Roofing 101 is licensed in Oklahoma under #80000806 and quotes in plain numbers, so you see exactly where every dollar goes.
