A replacement is the one roofing job where the shortcuts are invisible — until they aren't. Done right, it's a system: tear-off to bare deck, deck inspection and repair, underlayment, flashing, ventilation, and shingles installed to their manufacturer's specification. Here's how we do it and what it costs in Houston.
Angi's Houston data puts the average replacement at $9,752, with most projects between $6,712 and $13,123. By material, per square foot installed: asphalt shingles $4–$6 (about $4.65 average across materials at $4–$11), metal ≈ $11 (Houston metal average $10,995). Removing the old roof adds roughly $1–$3 per square foot where it's priced separately. The cost guide shows what moves the number: size, pitch, complexity, layers, and deck condition.
Most single-family replacements finish in 1–2 days — tear-off and dry-in on day one for most homes, so your house is never left open to the weather overnight. It's loud, and the yard is a work zone during it; pets and patio furniture should be inside. You do not need to leave home.
Shingles at or past their rated life across all planes; widespread curling, cracking or granule loss; recurring leaks in different places; storm damage across a large share of the roof; or an insurer or buyer requiring it. When a repair would honestly do, we'll quote the repair instead — see roof repair.
InterNACHI's expectancy chart lists about 30 years for architectural shingles and 40–80 for metal, with hot, humid climates at the low end — so plan on roughly 20–30 years for a quality architectural shingle roof in Houston, depending heavily on ventilation and storm luck. Anyone promising you a guaranteed 30 is selling.
Roof replacement in Houston generally requires a permit within city limits; suburbs and unincorporated areas vary. Your quote should say who pulls it — a roofer who can't answer that question clearly is telling you something.
Yes. Expect noise during working hours and keep pets indoors, but the home stays livable and is dried-in each night.
An inspector gets on the roof, checks the attic side too, photographs everything, and tells you — in writing — whether you need a repair, a replacement, or nothing at all. Most inspections take about an hour.
