Calculator provides a typical range based on Houston-area pricing. Actual cost depends on your specific roof — a written estimate is the only exact number.

What drives the final price?

Every job has its own variables. Here are the five things that move the number most:

✓ Material — The single biggest factor — jumping from shingle to metal changes the total significantly.
✓ Roof size and pitch — A steep or cut-up roof with multiple valleys costs more per square foot in labor than a simple two-slope.
✓ Tear-off and decking — Standard tear-off is included. Rotted or soft decking found underneath — common with Houston humidity — adds to the cost mid-project.
✓ Flat vs. pitched — Flat and low-slope roofs use different materials and detailing, especially around drains, scuppers, and parapets on commercial buildings.
✓ Permits — The City of Houston and surrounding jurisdictions require a permit for a full reroof. Reputable contractors include this in your quote.

Frequently asked questions

How accurate is this roof cost calculator?

It generates a realistic price range based on typical Houston-area contractor pricing for your material, home size, and roof type. It is not a substitute for an on-site estimate — for an exact number, a free written estimate is the right next step.

Why use home square footage instead of roof square footage?

Most homeowners know their home's square footage but not their roof's. We convert home area to estimated roof area using a typical pitch multiplier. If you know your actual roof square footage, the manual entry option gives a closer estimate.

Does this estimate include tear-off?

Yes — the estimate assumes a standard single-layer tear-off, new underlayment, flashing, and standard labor. It does not include plywood decking replacement, which is an additional cost if soft or rotted decking is found once the old roof is removed.

Are flat and commercial roof estimates different from pitched roofs?

Flat and low-slope roofs, common on Houston additions, older bungalows, and commercial buildings, use different materials and detailing. Select the flat/commercial option under roofing material — the calculator applies appropriate membrane pricing.
