Roofing Company - Written Price, Workmanship Warranty

Trusted Roofing Company Nationwide

Finding a roofing company you can actually trust shouldn’t feel like a gamble. Brennan Roofing operates under The Garrison Standard: a written price before any work starts, background-checked uniformed technicians who show up inside the promised window, and a full-year written guarantee on every job. We’ve been part of the Garrison Partners family since 2000, and every location is independently owned and operated to the same standard. If your roof is leaking, missing shingles, or nearing the end of its service life, call (361) 320-9467 and talk to a live person, not a voicemail. We answer around the clock.

Roofing Contractor

A Roofing Contractor is the licensed professional who installs, repairs, and replaces roofing systems on homes and commercial buildings. Brennan Roofing serves as your roofing contractor from the first inspection to the final nail, with a written scope of work and price before anything begins. Typical roof repairs run $350 to $1,600 depending on the extent of damage, while full replacement projects range from $8,500 to $45,000 based on roof size, pitch, material, and tear-off requirements. We don’t ask you to commit to a number we haven’t put on paper.

When You Need a Contractor

You need a roofing contractor when you see missing shingles, water stains on a ceiling, granules collecting in gutters, or daylight coming through the attic. Waiting on any of these signs lets water, rot, and mold move deeper into the decking and structure. A certified professional gets on the roof, documents what’s actually failing, and gives you a straight answer.

What Sets Our Crews Apart

Every technician who steps onto your roof is background-checked and arrives in uniform. That’s part of The Garrison Code, the set of operating rules each Brennan location agrees to follow. There’s no subcontractor roulette and no guessing who’s showing up at your door.

Commercial Roofing

Commercial Roofing covers low-slope and flat roof systems on warehouses, retail spaces, offices, and multi-family buildings. Brennan Roofing handles commercial roof repair, replacement, and coating with the same Garrison Standard that governs our residential work. Commercial roof repairs typically run $750 to $4,500 depending on membrane type and damage, while full replacement projects range from $35,000 to $200,000 or more based on square footage and system selection. Every commercial job starts with a written assessment and a fixed price before any work begins.

Flat and Low-Slope Systems

Flat roofs fail differently than pitched roofs. Standing water, seam separation, and membrane punctures are the three most common problems we document on commercial buildings. We inspect the entire field, all flashing points, and every penetration, then give you a prioritized repair list with real dollar figures attached.

Minimizing Business Interruption

A leaking roof over a retail floor or warehouse inventory isn’t just an inconvenience; it’s a liability. We schedule commercial work in phases when needed so your operation keeps running. You get a written timeline alongside the written price, and the crew shows up when we say they will.

Metal Roof Installation

Metal Roof Installation replaces an existing roof with standing seam, exposed fastener, or metal shingle panels. It’s one of the longest-lasting roofing decisions a property owner can make, and Brennan Roofing installs metal systems on both residential and commercial buildings. Metal roof installation typically costs $12,000 to $55,000 for a home and $40,000 to $200,000 for commercial buildings, depending on panel profile, gauge, finish, and the complexity of the roof geometry. The written price includes tear-off of the old roof when needed, new underlayment, panels, trim, and flashing.

Standing Seam vs. Exposed Fastener

Standing seam panels hide fasteners under raised ribs and cost more, but they accommodate thermal movement better and carry longer warranties. Exposed fastener panels cost less upfront and work well on simple roofs and agricultural buildings. We explain the difference in plain language and show you both options before you commit.

Why Metal Pays Back

Metal sheds snow, resists wind uplift, and reflects solar heat in warmer months. We’ve walked homeowners through 40-year and 50-year manufacturer warranties from brands we actually stock and install. When we give you a number, it includes the materials that’ll outlast the mortgage.

Residential Roofing

Residential Roofing is the installation, repair, and replacement of sloped roofing systems on single-family homes, townhomes, and small multi-unit buildings. Brennan Roofing focuses on asphalt shingle and metal residential systems, with material lines from GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko. A standard asphalt shingle roof replacement on a typical single-family home runs $8,500 to $22,000 depending on roof size, pitch, tear-off, and whether decking needs to be replaced. Repairs run $350 to $1,600 in most cases.

Asphalt Shingle Systems

Architectural shingles remain the most common residential roof in the United States for good reason. They balance cost, lifespan, and wind performance. We install them over new synthetic underlayment with new drip edge and flashing, not just over whatever the old roof left behind.

When Repair Isn’t Enough

A repair makes sense when damage is isolated. When shingles are brittle, granule loss is widespread, or the decking beneath is soft, replacement is the honest answer. We’ll show you photos from the roof and give you a written price either way, so you’re never making a blind decision.

Roof Maintenance

Roof Maintenance is the scheduled inspection, cleaning, and minor repair work that extends the life of an existing roof and prevents small failures from becoming full replacements. Brennan Roofing offers roof maintenance programs tailored to the building, with written inspection reports and fixed pricing for any needed follow-up work. Routine maintenance visits typically run $250 to $800 per visit depending on roof size and condition, with repairs quoted separately in writing before any work begins. The goal is simple: catch the two-dollar problem before it becomes the two-thousand-dollar one.

What a Maintenance Visit Covers

Each visit includes clearing debris from valleys and drains, checking flashing and pipe boots, documenting granule loss, and photographing any areas that need attention. You receive a written report after the visit, not a phone call with a vague summary. That report becomes your record over time.

Seasonal Timing That Protects You

Spring and fall are the two most important maintenance windows. Spring catches winter storm damage, and fall prepares the roof for freeze-thaw cycles and ice. We’ve seen maintenance visits uncover lifted flashing that would’ve leaked within a month.

Roof Coating

Roof Coating is a fluid-applied membrane that seals and protects low-slope and metal roofs, extending their service life without a full tear-off. Brennan Roofing applies silicone, acrylic, and elastomeric roof coatings on commercial buildings and some residential flat roof sections. Roof coating projects typically cost $3,500 to $25,000 depending on roof size, surface preparation, and the coating system selected. The price includes surface cleaning, seam reinforcement where needed, and application of the specified coat thickness.

When a Coating Makes Sense

Roof coating makes sense when the roof membrane is still structurally sound but aging, leaking at seams, or absorbing too much heat. It’s not the right move on a roof with widespread saturated decking or failed seams, and we’ll tell you that clearly if a coating would just delay an inevitable replacement.

Energy and Life Expectancy

White silicone and acrylic coatings reflect sunlight and reduce roof surface temperature, which lowers cooling load on the building. A properly applied coating can add 10 to 15 years to a roof’s service life. We specify the coating thickness in writing and apply it to the manufacturer’s requirements.

Free Roof Estimate

A Free Roof Estimate is a written, itemized price for your roofing project, prepared before you make any commitment. Brennan Roofing provides free roof estimates on every job, residential and commercial alike, and the number we write down is the number you pay. There’s no adjustment at the door, no “unexpected complication” that somehow doubles the price after materials are ordered. We document what we’ll do, what it costs, and how long it’ll take.

What the Estimate Includes

Every free roof estimate from Brennan Roofing includes material specifications, scope of work, timeline, and a firm price. We walk the roof, photograph problem areas, and show you what we found. That way, you’re pricing a real project, not a guess.

Why It’s Truly Free

Our roof estimate costs you nothing and obligates you to nothing. We do it because a homeowner who sees the work in writing, with a fixed price, can make a calm decision instead of a pressured one. That’s the entire point of The Garrison Standard.

Brands We Service

Brennan Roofing installs and services roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko. We hold manufacturer certifications with several of these lines, which means our crews are trained to install to each brand’s specifications and the warranty stays intact. If your existing roof is a CertainTeed or Owens Corning system, we know how it was designed to perform and what typically fails on it after years of weather exposure.

We also work extensively with IKO and Atlas shingle lines, and we’ve completed countless installations with their architectural profiles. Whether you have one of these brands or any other make, our roof inspection and repair process is the same: document the problem, price the fix in writing, and stand behind it for a full year.

Signs You Need a Pro Right Now

• Water stains on ceilings or walls. Water travels along rafters and decking, so the stain you see is often nowhere near the actual leak. A professional traces it to the source before the decking rots and the repair bill climbs.
• Missing or lifted shingles after a storm. Even one missing shingle exposes the underlayment and decking to direct rainfall. Nail pops and curled shingles signal a roof that’s losing its ability to seal against wind-driven rain.
• Granules in gutters or at downspout bases. Granule loss means the shingles’ protective surface is wearing away. Bare spots on shingles lead to cracking, then leaking, and by then you’re usually past the repair stage.
• Daylight in the attic. If you can see light coming through roof boards from inside the attic, water can get through too. This is one of the clearest warning signs and one of the fastest to diagnose.
• Sagging roof lines or soft decking. A sagging ridge or a spongy feel underfoot on the roof means structural moisture has already set in. Delaying this repair risks more than the roof; it risks the framing that holds it up.

If any of these signs are present, call (361) 320-9467 and we’ll send a background-checked technician to look at it. Roof repairs never fix themselves, and they never get cheaper with time.

Our Process, Step by Step

1. 1
   Inspection and documentation. A technician walks the roof and photographs everything; flashing, valleys, pipe boots, ridge caps, and decking. We use moisture meters where needed to find trapped water that isn’t visible on the surface.
2. 2
   Written scope and price. We put the work in writing: exactly what we’ll do, what materials we’ll use, how long it’ll take, and what it costs. No work starts until you’ve signed off on that number.
3. 3
   Scheduling and arrival. We schedule a date and arrive inside the promised window. The technicians you meet will be the same background-checked, uniformed crew who do the work.
4. 4
   Execution and cleanup. We protect the property, install or repair per manufacturer specifications, and haul away all old materials. Magnetic sweepers run across driveways and walk areas to collect stray nails.
5. 5
   Final walkthrough and warranty. We walk the finished job with you, answer every question, and hand you the written 365-Day Done Right Promise. If anything fails within that year, we come back at no charge.
