When a Houston roof is ready to be replaced
Roof replacement in Houston is a bigger decision than a repair, and the age printed on a shingle wrapper does not settle it. Sun, heat and storm after storm wear a Gulf Coast roof unevenly, so one house on a street can need a new roof years before the house next door.
What decides it is the condition of the shingles, the deck and the flashing, and how often water is getting in. This page walks through the signs that a roof is finished, what a replacement actually involves, the permit question, the materials homeowners here usually choose, and what the day of the tear-off is like.
Houston Expert Roofers does not replace roofs. Think of it as a switchboard that costs you nothing: an automated assistant picks up day or night, asks about the roof and your part of town, and transfers you to an independent, locally owned roofing company. That company inspects the roof, writes the quote, pulls any permit and handles the tear-off and install, and your payment goes to that company.
Signs the roof is finished, not just damaged
A single leak points to a repair. The signs below point to a roof that is wearing out everywhere at once. Most can be seen from the yard or from inside the house, so there is no reason to climb up and look.
Granules piling up
The colored grit on an asphalt shingle shields the asphalt from sunlight. A little washes off a new roof. A steady layer in the gutters or at the downspouts years later means the shingles are losing their protection and aging faster.
Curled or cupped edges
When the edges of shingles lift or the middles sink, the shingle has dried out and no longer lies flat against the course below. A curled shingle catches wind and lets rain run underneath it.
Leaks in more than one room
One stain is usually one failed part. New stains over the bedroom, the hall and the garage in the same season suggest a roof that is failing in several places, which is where patching stops paying off.
A soft or sagging deck
If the roofline dips between rafters, or the roofer reports soft decking across a wide area, the wood has taken on water over time. That is replaced during a tear-off, not covered over.
Daylight in the attic
Light showing through the deck anywhere other than a vent opening means there is a gap water can use too. Note it from the attic hatch and tell the roofer when you call.
Widespread storm damage
Hail bruising or wind creasing across several slopes rarely patches cleanly, and new shingles seldom match weathered ones. See hail damage and storm damage for how that is judged.
If a roofer recommends a whole new roof because of one leak, ask which of these signs it found and ask for photos. A second opinion is reasonable on a job this size. The roof repair page explains when a targeted fix is the better answer, and the roof lifespan guide covers how long different materials tend to hold up here.
What a replacement quote must spell out
Two quotes for the same house can look far apart simply because one leaves things out. Ask every roofer you talk to for a written, itemized quote covering each line below, so you are comparing the same job.
| Line in the quote | What it should say | Why it matters |
|---|---|---|
| Tear-off | How many existing layers come off and how debris is hauled away | Removing two layers is more work than one, and the count should not change after the job starts. |
| Decking | A price per sheet for any rotten or soft deck replaced | Nobody can see the whole deck until the shingles are off, so the unit price is what keeps the final bill honest. |
| Underlayment | The product name and type (felt or synthetic) | It is the layer that keeps water out if wind gets under a shingle. |
| Valleys and edges | How valleys are lined and that drip edge is installed at eaves and rakes | Valleys carry water from two slopes, and the residential code calls for drip edge on shingle roofs. |
| Flashing and boots | New flashing at walls and chimneys and new pipe boots, or a reason for reusing any | Old flashing on a new roof is a common source of the next leak. |
| Ventilation | Intake and exhaust vents, such as soffit and ridge vents | A hot, poorly vented attic is hard on shingles in a Houston summer. |
| Shingle | Maker, product line, color and impact rating if any | So you can check the exact product and register its warranty. |
| Permit | Who pulls it and which office issues it | A permitted re-roof gets a city inspection. |
| Warranties | The manufacturer warranty and the roofer's own workmanship warranty, listed separately | They cover different things, as explained below. |
| Schedule and payment | Start date, expected length and when each payment is due | So you know when to clear the driveway and what you owe at each stage. |
For what drives the price and published cost ranges, read the Houston roof replacement cost guide. The line itself never quotes prices.
Permits for a new roof in Houston and the suburbs
Inside the City of Houston, the Houston Permitting Center issues a residential roofing permit for any re-roof or overlay on a home. Its page says the permit involves plan review and an inspection, stays valid for six months, and must be kept on site until the final inspection is approved. If the job changes the framing that holds the roof up, plans have to be submitted as well. Only roof covering work of 100 square feet or less in total is exempt. Kingwood is inside the city, so the same rule applies there.
The city adopted the 2021 International Residential Code, with local amendments, for work from January 2024, according to the International Code Council. Among other things, the code's reroofing section (R908 in recent editions) does not allow a new roof covering to be laid over a roof that already has two or more layers. After the May 2024 derecho, Houston Public Works expedited re-roof and overlay permits and reminded owners that the work must also follow their neighborhood's deed restrictions.
Suburban cities such as Katy, Sugar Land, Pearland, League City and Conroe have their own building departments and their own rules, and homes in unincorporated Harris, Fort Bend or Montgomery County are handled differently again. Near the coast, in the Texas Department of Insurance catastrophe area, a new roof also has to pass windstorm inspections.
Coastal windstorm rules. In the Texas Department of Insurance's designated catastrophe area (Brazoria, Chambers, Galveston and the other first-tier coastal counties, plus, in Harris County, Morgan's Point and the parts of La Porte, Pasadena, Seabrook and Shoreacres inside city limits and east of State Highway 146), most roof work must meet the windstorm building code and be inspected while it is under way (TDI exempts repairs to less than 100 square feet of roof covering that do not touch the decking). When it passes, TDI issues a certificate of compliance (form WPI-8), which the Texas Windstorm Insurance Association uses to decide whether it can insure the home. Ask the roofer, in writing, who schedules the inspection and when you will get the WPI-8.
A roofer that works your area should know which office covers your address and should pull the permit in its own name. If a roofer suggests skipping the permit, that also skips the city's inspection of the work.
Materials Houston homeowners usually weigh
The roofer you are connected with will recommend a material for your house and budget. These are the common choices, described as general product information, not as an endorsement of any brand.
Architectural asphalt shingles
The most common choice on Houston houses. They are thicker and more dimensional than the older flat three-tab style. Each shingle has a strip of sealant that the sun heats until it bonds to the course below, which is why manufacturers say shingles installed in cold weather may take longer to seal.
Impact-resistant (Class 4) shingles
Roof coverings tested under the UL 2218 standard are rated Class 1 to 4; for Class 4, a two-inch steel ball is dropped from 20 feet onto the same spot twice without the product cracking, tearing or opening. The Texas Department of Insurance says a Class 4 roof qualifies for the largest premium credit, but each insurer sets its own discount and paperwork, so ask your insurer before choosing. Texas Property Code 202.011 limits an HOA's power to ban impact-resistant shingles that resemble the ones it allows.
Metal
Standing seam and other metal panels shed water quickly and suit Houston's heat, and some panels carry an impact rating too. Metal needs a roofer that installs it regularly, since the trim and fasteners are where it fails. See the metal roofing page.
Tile
Clay and concrete tile appear on some Mediterranean and Spanish style homes around Houston. Tile is heavy, so changing to it from shingles can mean checking the framing, which inside the city brings in the plan submission mentioned above.
Under the shingles, ask what underlayment is going on. It comes as traditional asphalt-saturated felt or as synthetic sheets, and the industry wrote a separate ASTM standard (D8257) for synthetic products in 2021. The product name should be in the quote.
Two warranties, two different promises
The manufacturer's warranty
This comes from the company that made the shingles and covers defects in the product. It does not cover mistakes in how the roof was installed, and many have a period of full coverage followed by a prorated period. Some require registration after the job. Ask the roofer to register it and send you the confirmation.
The roofer's workmanship warranty
This is the roofing company's own promise to fix problems caused by its installation, such as a flashing detail that leaks. It is only as good as the company behind it, so get the length and what it covers in writing, and ask how long the company has worked under its current name.
A shingle warranty with a big number of years does not help if the leak was caused by the install, and a workmanship warranty does not help if the company is gone. You want both in writing.
What install day is like
- Before the crew arrives. Move cars out of the driveway and garage approach, take fragile items off walls that share the roof framing, and bring patio furniture and grills away from the house. A dumpster or trailer is often parked in the driveway.
- Tear-off. The old shingles and underlayment come off, usually a section at a time so the house is not left open. This is the loudest part of the job.
- Deck check. With the deck exposed, the roofer replaces any soft or rotten sheets at the per-sheet price in the quote and should tell you how many it replaced.
- Dry-in and install. Drip edge, underlayment, valley lining, flashing and boots go on, then the shingles and ridge caps or vents.
- Cleanup and inspection. Ask how the crew will clean up, including running a magnet over the yard and driveway for loose nails. Inside the City of Houston, the permitted job then gets its city inspection. Keep the permit, invoice, photos and warranty papers together.
How long it takes depends on the size and pitch of the roof, the material and the weather, so ask the roofer for its estimate and what happens if rain moves in midway.
Start times, weekends and noise
People often ask what time roofers start work and whether they work on weekends. It varies from one roofing company to the next. OSHA's guidance to roofing employers recommends scheduling strenuous work for cooler parts of the day, which is one reason crews here tend to start early. Inside the City of Houston, the noise ordinance (Chapter 30) sets sound limits measured at the receiving property line, lower at night than in the day, and is enforced by the Houston Police Department. Deed restrictions and HOA rules can be stricter about hours and weekend work. Ask the roofer for its start time and work days in writing, and warn your neighbors.
Timing around storm season
The Atlantic hurricane season runs from June 1 through November 30. Right after a hail or wind event, many roofers are booked solid and door-to-door crews appear. If your roof is worn but holding, scheduling the replacement away from those rushes gives you time to compare quotes and check each company.
Not sure whether your roof needs replacing or one good repair? Call and describe what you see. The local roofing company you are put through to looks at the roof in person and puts its recommendation and price in writing.
Questions to ask before you sign
- Which signs of wear did you find, and can I see your photos of the roof and the attic?
- Is this a full tear-off, and how many layers are coming off?
- What is your price per sheet of decking, and will you show me what you replaced?
- Which shingle, underlayment and vents are you using, by product name?
- Who pulls the permit, and which office issues it for my address?
- Will you register the manufacturer's warranty, and what does your own workmanship warranty cover?
- Can you send your certificate of liability insurance before work starts?
- What time does the crew start, which days do you work, and where will the dumpster go?
If insurance may be paying for the roof, read the roof insurance claims guide before you sign anything. You file the claim, and the deductible is yours.
How a replacement call works
- Call the numberAn automated assistant answers (832) 662-4107 at any hour and asks which service you need, since the line also takes heating, cooling, pressure washing and water damage calls.
- Describe the roofA leak, missing shingles, hail, a limb on the roof or an old roof you want looked at, plus your part of greater Houston and how urgent it is.
- Get put throughYour call is transferred to an independent, locally owned roofing company, which hears a short summary before it picks up.
- Deal with the roofer directlyIt inspects, quotes and does the work, and you pay it (or your insurer does, as you arrange). If it misses the call, it gets your name, number, city and need to call you back.
Texas has no state roofing license. No state agency licenses roofing contractors in Texas, and a 2025 bill to create one (HB 3344) did not reach a vote of the full House before the session ended. So check what you can: a certificate of liability insurance sent to you, a written contract with the full scope, a permit where your city requires one, local addresses you can drive past, and the shingle maker's warranty registration. Some cities also ask roofers to register. The line does not check any of this for you. How to check a roofer before you hire.
The deductible is yours to pay. The Texas Department of Insurance says it is illegal for a contractor to offer to waive, rebate or absorb your deductible, and a contract of $1,000 or more paid with insurance money must include a notice saying so. A roofer also may not act as your public adjuster on a property it works on. Treat any offer to "cover the deductible" as a reason to call someone else.
