Roof Cost Calculator for Dallas, TX
Curious what a new roof might cost on your house in Dallas, TX? Answer four short questions and this calculator works out a rough roof size, then prices it with 2026 Texas cost figures. It gives you a budgeting number to carry into the conversation before a local roofer measures and prices the actual job.
Instructions
Before you start. Your living space is divided by the number of stories to get the footprint. That is multiplied by a slope factor (1.12 for a walkable roof, 1.30 for a steep one), plus 10% for eaves and overhangs, and the roof area is priced per square foot.
The five cost rows below are 2026 averages for Texas as a whole; no published guide breaks out Dallas alone. Shingle results run from the 3-tab row to the premium row; metal results run from exposed-fastener panels to standing seam.
| Cost row | Figure | Source (year) |
|---|---|---|
| Texas 3-tab shingles, per sq ft | about $4.35 | RoofObservations, 2026 |
| Texas architectural shingles, per sq ft | about $4.80 | RoofObservations, 2026 |
| Texas premium shingles, per sq ft | about $5.95 | RoofObservations, 2026 |
| Texas exposed-fastener metal, per sq ft | about $6.45 | RoofObservations, 2026 |
| Texas standing-seam metal, per sq ft | about $9.95 | RoofObservations, 2026 |
The tool is meant for pitched roofs covered in shingles or metal. Tile, slate and flat roofs vary too much for a formula, so each of those needs a roofer's own quote. Extra layers, soft decking or many valleys can lift the real price.
What to Do With the Result
Keep the range handy when estimates arrive. If a written figure lands far from it, ask the roofer to walk you through the measured squares, tear-off, underlayment, ventilation and the per-sheet price for any decking swapped out.
A full re-roof in Dallas needs a City permit, which a contractor registered with the City can pull (or an owner doing the work on a homestead). Ask who will handle it before you sign.
When you want a real number, request an estimate below. Your request goes to one independent local roofer, who pays this site for the referral; using it costs you nothing.
