Full Roof Replacement in Houston, TX

Full Roof Replacement in Houston, TX

A full roof replacement in Houston means tearing off the existing roof down to the decking, inspecting what’s underneath, and installing an entirely new roofing system. For most Houston homes, this runs between $12,000 and $28,000 depending on square footage, roof pitch, and material choice, with architectural asphalt shingles being the most common option. Brennan Roofing Co Houston does full replacements under Roof Replacement & Installation, and every job starts with a written price before any work begins. Call (940) 461-8481 to schedule a free estimate.

Houston roofs take a beating. Between the Gulf Coast humidity, hurricane season from June through November, and the hail that comes with spring thunderstorms, a roof here ages faster than it would in Dallas or San Antonio. When repairs stop making financial sense, a full replacement is the square move. Travis Oakley runs Brennan Roofing Co Houston to what we call The Garrison Standard, which means background-checked technicians in uniform, a live person on the phone around the clock, and a written guarantee on every single job.

If you’ve been burned before by a roofer who no-showed, changed the price at the door, or left nails in your yard, this page tells you exactly how we work differently. No vague promises. Specifics.

When You Need Full Roof Replacement

Not every roof problem calls for a full replacement. Some are repair jobs. But when these conditions show up, you’re usually past the point where patching makes sense:

• Shingle granule loss across large sections. Check your gutters after a rain. If they’re full of gritty granules and your shingles look bald in patches, the asphalt layer is failing. In neighborhoods like Meyerland and Westbury where homes were built in the 1960s and 70s, we see this constantly.
• Curling, cracking, or missing shingles after a storm. Houston gets hit with hail often enough that insurance claims are a regular part of our work. If you can see cracked shingles from the ground in Bellaire or Sugar Land, the roof is compromised and water is finding its way under the surface.
• Water stains on ceilings or walls after heavy rain. A leak is never just at the spot where you see the stain. Water travels along rafters and decking. By the time it shows up inside, the roof above has likely been leaking for weeks or months.
• Soft spots or sagging when you walk the roof. This usually means the decking underneath has rotted from trapped moisture. In Houston’s humidity, a small leak can turn into a decking failure quickly. We’ve replaced roofs in Katy and Spring where the decking was so far gone you could push a screwdriver through it.
• Your roof is 20+ years old and was struck by hail. Most asphalt shingle roofs in Houston fail between 15 and 25 years. If your roof is past 20 and sustained hail damage, your insurance adjuster will likely recommend full replacement anyway. Age plus damage equals replacement in almost every case.
• Flashing failures around chimneys, skylights, and valleys. Flashing is the metal that seals the seams where roof planes meet or where things poke through. When flashing fails, you get slow leaks that rot decking from underneath. On a roof that’s already aging, replacing only the flashing is a stopgap, not a fix.

If you’re seeing two or more of these signs, a full replacement is likely cheaper than repeated repairs over the next few years. Call (940) 461-8481 and we’ll do an honest inspection. If the roof only needs repair, we’ll tell you that. We do repairs too.

Our Full Roof Replacement Process

Here’s how a full roof replacement with Brennan Roofing Co Houston works, step by step:

1. Inspection and written estimate. Travis Oakley or one of our background-checked technicians walks the roof, checks the decking, flashing, and ventilation, and then puts a price on paper. Not a verbal ballpark. A written number. That price does not move at the door.
2. Material selection. We walk you through your options, including architectural shingles from GAF, CertainTeed, and Owens Corning. Each has different warranties, wind ratings, and price points. We explain the differences in plain English so you choose with confidence, not guesswork.
3. Tear-off and decking inspection. The crew strips the old roof down to the decking. This is where we find what’s hiding underneath: rotted plywood, termite damage, failed underlayment. Any decking that needs replacement gets discussed with you on the spot, with pricing before we proceed.
4. Underlayment and flashing installation. We install a full synthetic underlayment over the decking. This is your last line of defense against Houston’s wind-driven rain. Then we replace or repair all flashing: drip edge along the eaves, step flashing at walls, and flashing around chimneys, vents, and skylights.
5. Shingle installation and ridge vent. Shingles go on in the correct pattern for the manufacturer’s wind rating. We install or replace ridge vent along the peak to let hot air escape, which matters a lot in Houston attics that hit 130 degrees in August.
6. Cleanup and final walkthrough. We run a magnetic roller over the yard for nails, clear the gutters of debris, and walk the finished roof with you before we leave. You get the 365-Day Done Right Promise in writing: if anything is not done right within one year, we come back and make it right at no charge.

Every step of this process runs on The Garrison Code: the price is written before work starts, the technicians are uniformed and background-checked, and the phone is answered by a live person, any time of day or night. Home page has the full picture on how we operate.

Full Roof Replacement Pricing in Houston

A full roof replacement in Houston typically costs between $12,000 and $28,000. The average is around $17,500 for a 2,200 square foot single-story home with architectural shingles. Here’s what drives the number:

• Square footage and roof pitch. A 3,000 square foot two-story in Memorial costs more than a 1,400 square foot ranch in Pasadena. Steeper roofs cost more because the crew works slower and safety setup takes longer.
• Material choice. Three-tab shingles are the cheapest but aren’t rated for the wind speeds Houston sees during hurricane season. We don’t recommend them. Architectural shingles from GAF or CertainTeed run mid-range and come with better wind ratings. Boral tile or slate runs significantly more but lasts decades longer.
• Decking condition. This is the variable that surprises homeowners most. If the decking underneath is rotted, that plywood has to be replaced at $2 to $4 per square foot of affected area. On older homes in the Heights or Montrose, you should expect some decking replacement. We identify this during the inspection so there are no surprises on install day.
• Number of roof penetrations. Chimneys, skylights, vent stacks, and valley seams all add flashing work. A roof with five valleys and three skylights costs more than a simple rectangle.

Ballpark ranges for a typical 2,200 square foot Houston home:

• Three-tab asphalt shingles (installed): $9,500 to $14,000
• Architectural asphalt shingles (installed): $12,000 to $18,500
• Standing seam metal (installed): $24,000 to $40,000
• Boral tile or slate (installed): $35,000 to $70,000+

Those numbers are honest ranges, not lowball teasers. The only way to get a real number is to have us walk the roof. Estimates are free, and the price we put on paper is the price you pay. No door-knock discount games, no creep-up at the end. Just a written number before any work starts.

If you’re deciding between full replacement and repeated repairs, the math usually tips toward replacement once repair costs exceed 40% of replacement cost on a roof that’s 15 or more years old. We’ll tell you straight which side of that line you’re on.

FAQs – Full Roof Replacement

How long does a full roof replacement take in Houston?

Most full roof replacements in Houston take 1 to 3 days, depending on roof size, pitch, and weather. A straightforward 2,000 square foot single-story is usually done in a day with a full crew. Steeper roofs, two-story homes, and any decking replacement add time. Houston’s afternoon thunderstorms in summer sometimes mean we pause work and resume the next morning, which is normal and planned for. Call (940) 461-8481 and we’ll give you a realistic timeline for your specific roof.

Is it cheaper to repair or replace my roof in Houston?

It depends on roof age and the extent of damage. If the roof is under 10 years old and the damage is isolated, a repair is usually cheaper and makes sense. If the roof is 15+ years old and damage covers more than 40% of the surface, replacement is the better financial move because repairs will keep stacking up. Our inspection tells you which way to go, and we don’t push replacement when a repair will do the job.

Can you install a new roof over my existing shingles in Houston?

We don’t recommend it, and in many Houston jurisdictions it’s not allowed under current code. A roof-over hides decking problems, adds weight to the structure, and shortens the life of the new shingles because they can’t seal properly over an uneven surface. A full tear-off lets us see the decking, replace what’s rotted, and install the new system correctly so the manufacturer’s warranty is valid. The tear-off costs a bit more up front, but it’s cheaper than finding rot problems three years later.

Will my Houston homeowners insurance cover a full roof replacement?

It depends on your policy and the cause of the damage. Most Houston policies cover hail and wind damage, which are common here. We work with your insurance adjuster, document everything with photos, and walk the roof with them when needed. What we don’t do is promise a free roof or encourage you to file a claim that isn’t legitimate. Honesty about what’s actually covered is part of The Garrison Standard. Call (940) 461-8481 and we’ll help you figure out what your policy covers.

What warranty comes with a full roof replacement from Brennan Roofing Co Houston?

Two warranties apply. The manufacturer’s warranty covers the shingles themselves, typically 25 years to lifetime on architectural shingles from GAF or CertainTeed. Our 365-Day Done Right Promise covers our workmanship in writing for one full year. If anything we installed fails within that year, we come back and fix it at no charge. No fine print about weather exclusions, no runaround. It’s written, it’s specific, and it’s backed by a company that answers the phone with a live person.

Why Brennan Roofing Co Houston

Here’s the honest version. Houston has hundreds of roofing companies. Some of them are talented. Some of them disappear after the first hailstorm. The problem isn’t finding a roofer. It’s finding one you can hold accountable when something goes wrong.

Travis Oakley founded this company around a simple idea: operate under a defined standard and put it in writing. The Garrison Standard means you get a price on paper before any work starts. It means the technician who shows up at your door is background-checked, in uniform, and has a name tag. It means the phone is answered by a live person 24/7, not a voicemail queue. It means every job gets a written one-year guarantee, and if something fails, we return for free.

We install materials from GAF, CertainTeed, Owens Corning, and Boral. We explain the differences honestly, including which materials hold up to Houston’s specific climate challenges: wind-driven rain, brutal UV exposure, and hailstorms that roll through every spring. We don’t upsell you into a material that doesn’t make sense for your house.

Brennan Roofing Co Houston is independently owned and operated as part of the Garrison Partners family, founded in 2000. That means we’re a local Houston business, not a faceless chain. Travis Oakley is the name behind the company, and accountability starts with him.
