Why Austin Homeowners Choose GAF Construction
We provide independent GAF service in Austin, with crews that inspect and repair Timberline HDZ, Timberline UHDZ, and Camelot II systems every week. The work we do is not bound to GAF-authorized processes, which means we can recommend the repair that actually makes sense for your roof rather than the one a manufacturer checklist dictates. Call (903) 623-1966 for a free estimate on any GAF roof issue in Austin, from storm damage to granule loss.
GAF is the most common residential shingle brand on Austin homes for good reason. The Timberline series handles Texas sun better than many competitors, and the Camelot II profile gives older and custom homes a heavier architectural look that suits central Austin’s bungalow stock. But these roofs do not age the same way here as they do in, say, a coastal climate. Austin’s combination of intense UV, flash-flood moisture, and spring hail creates wear patterns we see so often we can usually diagnose a roof from the street before we climb the ladder. As an independent GAF service provider, we are not authorized by GAF, and we think that is an advantage: our recommendations are driven by what the roof actually needs, not what a warranty program prefers.
Why Trust Mason Remodeling Co Austin for Your GAF Construction?

Isaac Pruett, the owner behind Mason Remodeling Co Austin, learned the construction trade at Los Angeles Trade-Technical College and spent years on residential and commercial work up and down the West Coast before bringing his crew to Austin. He has been on hundreds of GAF roofs in this city, including plenty of work in the Mueller neighborhood, and he trains every technician to treat a roof inspection the way a diagnostician treats a patient: slow, systematic, and not done until the cause is found. That matters because GAF roofs fail in predictable ways that are easy to misdiagnose if you are in a hurry.
Every Mason Remodeling technician arrives in a clean, marked uniform with a photo ID badge at the door, and you will receive the name and photo of the person coming before the visit. That is the Threshold Standard, and it applies to every GAF inspection, repair, or replacement we do in Austin. We deliver a written price before any work starts, and every completed GAF job is covered by our 365-Day Done Right Promise: if the work is not right within a year of completion, we make it right at no cost to you. That is not a warranty quote buried in fine print. It is the term we write on the estimate.

Common GAF Construction Problems We Fix in Austin
These are the issues we see most often on GAF roofs in Austin, and we know the specific causes behind each one.
- Blistering and granule loss on Timberline HDZ shingles. Prolonged Austin sun bakes the asphalt in the shingle, and over 8 to 12 years, the granules on the west and south slopes start to loosen and wash into the gutters. You will see bald spots, especially near the eaves where heat collects. This is not a manufacturing defect as often as it is heat fatigue, and it reduces the shingle’s ability to shed water.
- Wind uplift and creased shingles on ridge lines after severe thunderstorms. Austin spring storms bring straight-line winds that catch the shingle tabs along roof ridges. Older Timberline HDZ installations with inconsistent nailing patterns are especially vulnerable. A creased shingle leaves a hinge point that wind can work back and forth until a tab tears off entirely. We re-nail or replace those sections before the next storm turns a crease into a missing shingle.
- Flashing failures around chimneys and skylights on Camelot II roofs. The Camelot II is a heavier, thicker shingle profile, and that changes how step flashing must be cut and layered. If the original installer used standard offset flashing or cut corners on the counter-flashing, you will get slow leaks around the chimney or skylight that show up as attic staining months before water drips through the ceiling. Shingles look fine from the ground. The flashing is the failure point.
- Algae streaking and discoloration on north-facing slopes. Austin’s shaded neighborhoods, especially in central areas with mature oak canopies, hold moisture on north-facing roof planes. GAF shingles have algae-resistant granules, but over time, the copper coating diminishes and the streaking appears. It is largely a cosmetic issue, but it signals persistent moisture retention, and in some cases, moss can take hold and lift shingle edges.
- Hail damage with hidden structural bruising. Hail does not always leave obvious dents on GAF shingles. On Timberline HDZ, small hail can bruise the fiberglass mat under the granule layer without showing visible damage from the ground. The shingle loses impact resistance and will fail early. We find this by running a chalk test and pressing our thumbs across the shingle surface, the way an appraiser would.
One thing worth saying plainly: after a spring hailstorm in Northwest Austin, we responded to a 12-year-old GAF Timberline HDZ roof with cracked shingles along the west-facing slope and granule accumulation in the gutters. Water staining in the attic confirmed the breach. Our crew replaced the damaged field shingles, re-sealed all pipe boots and vents, and installed a new ridge vent, matching the existing Weathered Wood color exactly. The homeowner avoided a full tear-off and the roof sheds water correctly again. That is the kind of GAF in Pflugerville and throughout the area that we do: fix what is broken, verify what is not, and keep the roof functioning as long as it honestly can.
GAF Parts & Our Repair-vs-Replace Approach

We use genuine GAF replacement shingles and accessories whenever possible, because matching the exact color and profile of your existing roof is the difference between a repair you cannot see and one that stands out from the street. GAF’s color blends are specific; a close-but-not-exact aftermarket shingle looks wrong in daylight. So for field shingles, ridge caps, and hip and ridge pieces, we source genuine GAF product. For flashing, underlayment, and pipe boots, we will install high-quality aftermarket components if the GAF part is discontinued or unavailable, and we will tell you that is what we are doing before we do it.
When a roof is older than 15 years and has widespread granule loss or leaks in more than one area, we are honest about the math. Repeated section repairs on a failing roof can cost more over three years than a full Timberline HDZ replacement. We will show you the numbers both ways and let you decide. Call (903) 623-1966 to get a written estimate for either path.
Our GAF Service Process – Step by Step
- 1
Diagnosis. We start with a full inspection: shingle condition, flashing integrity, nailing patterns on ridge and edge, attic ventilation, and signs of moisture or hail. On GAF Timberline roofs, we specifically check for hidden bruising using a chalk test, not just a visual pass from the ladder.
- 2
Repair or replacement plan. We write up exactly what needs to be done, with line-item pricing for materials and labor. If a section repair will not hold, we say so. If a full replacement is the better long-term move, we show you the comparison.
- 3
Repair or installation. For repairs, we remove damaged shingles, replace flashing where needed, re-seal boots and vents, and install a matching GAF shingle in the correct pattern. For full replacements, we tear off to the deck, inspect the decking, install new underlayment, and lay the GAF system according to the manufacturer’s high-wind installation standards.
- 4
Testing. We water-test repaired areas where possible, check attic ventilation, and confirm the roof sheds water correctly before we call the job done. You also get a written guarantee stating what is covered and for how long: 365 days from completion.

AfterGAF Products We Service & Install in Austin
We service and install the full GAF architectural shingle line that Austin homeowners actually have on their roofs:
- GAF Timberline HDZ – the most common shingle we see, and the one we repair most often. We stock several HDZ colors locally for fast section repairs.
- GAF Timberline UHDZ – a heavier shingle with Class 4 impact resistance. We install these on Austin homes where hail is a recurring concern, particularly on the west and north sides of the city.
- GAF Camelot II – a premium architectural shingle with a distinctive shadowing profile. We handle repairs on these most often around chimneys and skylights, where flashing failures are common.
- GAF Grand Sequoia – a thicker, hand-split look. Less common in Austin, but we source and match it when it appears.
We Also Service These Brands
GAF is a big part of the roofing work we do in Austin, but it is not the only brand we stand behind. Our cabinetry and surface teams work with KraftMaid, Cambria, Silestone, and Kohler on kitchen and bath projects through our General Contractor services, and our crews carry the same Threshold Standard across every job. If your home needs roofing work today and a kitchen remodel next year, you will deal with the same company, the same verification process, and the same written-price promise.
FAQs – GAF Construction Service in Austin

A section repair is possible if the roof is under about 15 years old, the damage is localized, the shingles still have granule life, and the flashing is sound. We repair sections when the rest of the roof has five or more years of life left. When granule loss is widespread or you have leaks in multiple areas, a full replacement is usually the better long-term value. Call (903) 623-1966 and we will inspect and give you both options in writing.
Yes. GAF Timberline UHDZ is a Class 4 impact-rated shingle, which makes it a strong choice for Austin areas that see repeated spring hail. We install UHDZ on homes in north and west Austin and provide GAF service in Round Rock, where hail paths are common. It costs more than standard HDZ, so we will show you the price difference before you commit. Call (903) 623-1966 for a written estimate.
No, it is algae. GAF shingles have algae-resistant granules, but the copper coating diminishes over time, and shaded north slopes in Austin hold moisture long enough for streaking to develop. It is cosmetic in most cases, not a material defect. We can clean the roof safely and recommend options to slow recurrence, but a manufacturer defect claim is not the right route for algae streaking. Call (903) 623-1966 for an inspection.
The leak is usually in the step flashing or counter-flashing, not the shingles. On Camelot II and other heavier GAF profiles, flashing must be cut and layered precisely, and if the original installer took shortcuts, water gets behind the flashing and stains the attic. The shingles above and below the chimney will look perfectly intact. We find and repair these flashing failures every month in Austin. Call (903) 623-1966 for a free estimate.
In most cases, yes. We stock several GAF Timberline HDZ colors locally, including Weathered Wood, Charcoal, and Barkwood, and we order additional colors from our local supplier, usually with a day or two of lead time. For older roofs, there may be slight color difference from sun fading on the existing shingles, and we will tell you that honestly before we install. Call (903) 623-1966 if you need a color match.
A GAF Timberline shingle roof repair on a small section or single leak typically runs $400 to $1,800. A full roof replacement with Timberline HDZ on a typical 1,500 sq ft Austin home falls between $8,000 and $20,000. Emergency tarp and temporary sealing after storm damage before full repair ranges from $250 to $700. All estimates are written and line-itemed, and your price does not change once work starts. Call (903) 623-1966 for an exact quote.
