Before you start, it helps to know how the number is built. The calculator divides your living space by the number of stories to get the footprint, adds for roof pitch and the overhang at the eaves, then multiplies that roof area by a low and a high rate per square foot. The rates are set to cover the cost rows below.
| Cost row | Figure | Source (year) |
|---|---|---|
| Texas asphalt shingles, per sq ft | about $4.92 | This Old House, 2026 |
| Houston-area asphalt shingles, per sq ft | about $4–$6 | HomeBlue, 2024 |
| Texas metal roofing, per sq ft | about $9.55 | This Old House, 2026 |
| Houston-area metal roofing, per sq ft | about $6–$10 | HomeBlue, 2024 |
The shingle range runs from standard architectural shingles up to Class 4 impact-resistant ones. The metal range runs from exposed-fastener panels up to standing seam. Katy households average 3.15 people (Census), so plenty of homes here land in the larger size bands.
After the Result
Treat the range as a starting point for a budget conversation. Replacement boards for soft or damaged decking are a common extra that no calculator can see, and inside the City of Katy the job also needs a City permit, which your roofer pulls.
