Roof Replacement in Houston, TX

A roof replacement removes the old covering down to the wooden deck, repairs any bad decking, and installs a new system: underlayment, flashing, drip edge, ventilation and the finished shingles or metal. The material you pick drives most of the cost. This Old House's guide (updated October 2026) puts asphalt shingles at about $5.16 per square foot and metal at about $19.30 per square foot nationally, with a 2,000-square-foot asphalt roof budgeted near $10,300. Those are national averages, not Houston quotes.

When replacement makes more sense than repair

Replacement is usually the right call when the problems are spread across the roof rather than in one spot. Signs include shingles that are brittle, curled or bald of granules on several slopes, leaks that keep appearing in new places, or soft decking you can see sagging between rafters. Age is part of it: This Old House lists a 30–35 year lifespan for asphalt shingles, but long Gulf Coast summers can shorten that on a poorly ventilated attic. If you are unsure, our repair-or-replace guide walks through the decision.

Choosing the covering

• Architectural shingles. A common choice on Houston-area homes. Two bonded layers give a thicker, dimensional look. Wind ratings differ between product lines, so ask for the exact product name and the rating printed on its packaging.
• 3-tab shingles. A single flat layer cut into three tabs. Cheaper per bundle, flatter in appearance, and harder to match years later.
• Impact-rated shingles. Hail is a real risk around Houston. Shingles that pass the UL 2218 Class 4 test (a 2-inch steel ball dropped from 20 feet) carry the highest impact rating, according to GAF, which notes that only packages bearing the UL 2218 classification statement are rated. The Texas Department of Insurance says your insurer may offer a discount for materials less likely to be damaged by wind, hail or fire, so ask your agent before you choose.
• Standing-seam metal. Panels joined with raised seams and concealed clips, with no exposed screws through the face. This Old House lists a 40–70 year lifespan for metal. It needs its own flashing details at walls, valleys and pipes, so expect a separate scope, not a line item swap.
• Low-slope membranes. A flat porch or back addition usually gets TPO or modified bitumen, not shingles. Make sure the quote covers that section separately.

The parts you don't see

Two quotes for "a new roof" can differ by thousands because of what sits under the shingles. A complete scope names:

• Tear-off. How many existing layers will come off. This Old House notes that codes often allow two layers of asphalt and that an overlay is cheaper, but a tear-off lets the contractor see the deck.
• Decking. The price per sheet for replacing rotted plywood or OSB, and a promise to photograph it and get your approval before adding it.
• Underlayment. Felt or synthetic, and whether ice-and-water membrane goes in valleys and around penetrations.
• Drip edge and starter strip. New metal at the eaves and rakes, and an adhesive starter course so the first row of shingles holds in wind.
• Flashing. Whether step flashing, chimney flashing and pipe boots are new or reused. Reusing rusted or bent metal saves money now and causes leaks later.
• Ridge cap and ventilation. GAF recommends balancing soffit intake with ridge exhaust, sized by its 1:300 rule, and warns against mixing exhaust vent types. A new roof is the cheapest time to fix an unbalanced attic.

Permits and HOA approval

The City of Houston requires a residential roofing permit for a re-roof or roofing overlay. The Houston Permitting Center lists plan review, a 10-business-day processing time, a re-roof worksheet (form CE-1109) or overlay form (CE-1104), and an inspection with the permit and worksheet on site. Ask the contractor to pull it and give you a copy. Addresses outside Houston city limits use their own city or county office, so check our pages for Sugar Land and The Woodlands. Many neighborhoods also require HOA approval of shingle color before work starts.

Planning the job day

Ask the contractor how long your job should take and what happens if rain moves in with the deck exposed. Before the crew arrives, move cars out of the driveway, take fragile items off walls (nailing shakes the house), and decide where the dumpster and shingle delivery can go without damaging the lawn or septic area. Ask how the crew will collect nails from the yard and protect AC units and plants.

What a good replacement quote lists

• the shingle or metal product, color and wind or impact rating;
• the number of layers removed and the decking price per sheet;
• underlayment type and where ice-and-water membrane goes;
• new versus reused flashing, drip edge, pipe boots and vents;
• the permit, who pulls it, and the final inspection;
• payment terms tied to stages of work, and any written manufacturer and workmanship warranties.

Common questions

How much does a new roof cost in Houston?

There is no verified Houston-only survey. This Old House's October 2026 national figures put asphalt shingles near $5.16 per square foot and metal near $19.30, before extras like decking repair. A local pro can quote your actual roof.

How long does a shingle roof last in the Houston climate?

This Old House lists 30–35 years for asphalt shingles nationally. Heat, attic ventilation, hail and installation quality all affect how long a given roof lasts.

Will insurance pay for a new roof because mine is old?

No. The Texas Department of Insurance says insurers won't pay for a new roof just because it is old or worn. Coverage applies to covered damage such as a storm.

Do I need a permit for a roof replacement in Houston?

Yes, within City of Houston limits a re-roof needs a residential roofing permit and an inspection. Suburbs have their own rules.
