GAF Construction in Irving, TX | Penhallow Remodeling Dallas
GAF roofing service in Irving means handling two things at once: the storm damage North Texas throws at shingles, and the clay soil movement that stresses the slab under the house. We’re Penhallow Remodeling Dallas, and our Gaf specialists provide independent GAF installation and repair across Irving, from Hospital District slab homes to the low-rise apartment complexes off Belt Line. The one thing that makes our GAF work here different is that we plan for both problems before the first shingle comes off. Call (940) 204-5368 for a free estimate.
Why Irving Residents Choose Us for GAF Service

We’ve worked GAF roofs in Irving long enough to know which accessories actually hold up here and which ones quietly fail. StormGuard leak barrier earns its keep when a May microburst rips across the southern side of the metroplex. Cobra ridge vents matter in July when attic temperatures climb past 140 degrees. These aren’t upsell items in our book; they’re the difference between a roof that lasts and one that sheds granules into the gutters by year three.
Trevor Nash runs our Dallas-area crews, and he came up through years of hands-on roofing and our General Contractor in Irving work before landing here in Irving. He’s the kind of contractor who wants you to see the written price before anyone sets foot on a ladder, because that’s how he’s always operated. “Give you a number before I pick up a tool – that’s the only way I know how to start.” Our technicians are background-checked and arrive in uniform, so you know exactly who’s walking your property. And since each Penhallow location is independently owned and operated within the Kingswell family of companies, we hold ourselves to The Kingswell Way on every job: written price up front, defined arrival window, clean job site, and a written guarantee when we finish.

Common GAF Construction Problems We Solve in Irving
Here’s what we see week in and week out on Irving roofs:
- Wind-lifted or torn Timberline shingles along gable edges and eaves. Irving’s microbursts hit two-story 1970s brick veneer homes hard, especially where the original install skipped starter shingles or skimped on nails at the rake. The wind catches the shingle corner, folds it back, and suddenly the underlayment is exposed to the next storm.
- Hail fractures on Timberline UHDZ granule surfaces. A March hailstorm can bruise shingles without punching through them. The granules crack loose, and the damage sits there invisible until a later rainstorm soaks the mat and the homeowner finds water staining a ceiling. We inspect for these fractures specifically because they’re easy to miss from the ground.
- Wrinkling and tenting of EverGuard PVC on low-slope apartment roofs. Over near the Hospital District, we’ve seen mechanically fastened EverGuard membranes buckle in the heat because the fastening plates were torqued too tight. The PVC expands in August, has nowhere to go, and tents up at the seams.
- Premature granule loss from box-vent-only ventilation. Irving’s humid summers mean attic moisture and heat build up fast. If the roof only has box vents and no ridge or intake ventilation, the shingle mat cooks from underneath. Granules start washing into the gutters within a few years of a new roof.
- Granule-clogged plumbing vent flashing on older cast-iron systems. This one’s specific to Irving’s 1960s slab homes. Loose granules from an aging roof wash into the vent flashing, clog the weep holes, and force water back up under the shingles. It looks like a flashing leak, but the root cause is the old cast-iron vent itself.
GAF Service in Irving: What Local Conditions Mean for Your Equipment
Here’s a coordination fact about Irving that builders in newer cities rarely have to think about. The older slab homes in Hospital District and Del Rancho, the ones from the 1960s and early 70s, often have two problems running at the same time: expansive clay soil pushing the slab up in the center, and original cast-iron waste lines corroding from the inside. Many of these same properties also need Bathroom Remodeling in Irving to address the aging plumbing. When we replace a GAF roof on one of these properties, we can’t just drop a dumpster on the driveway and start tossing shingles. The perimeter of the slab is often already stressed, and a fully loaded dumpster parked at the wrong corner can add pressure where the homeowner doesn’t need it. So we place debris chutes and position dumpsters carefully, often in the street with the city’s permission, to avoid loading any part of a slab that’s already moving. That’s a coordination step you won’t see mentioned on a generic GAF page, but it’s routine for us here.
GAF Models & Products We Service in Irving
We install and repair the GAF lines that perform in North Texas: Timberline HDZ and UHDZ shingles for sloped residential roofs, EverGuard PVC membrane for low-slope commercial and apartment buildings, and EnergyCap rigid cover board where insulation and hail resistance are both in play. For warranty-intact repairs, we use genuine GAF replacement shingles and accessories. When a Timberline color has been discontinued, we source from GAF’s matching line, and we’ll use a quality aftermarket color-match shingle only when a full replacement isn’t in the budget and you understand the tradeoff. We keep common GAF accessories stocked locally for fast Irving turnaround: StormGuard leak barrier, Cobra ridge vents, standard hip and ridge caps, and the fasteners and flashing that hold everything down.

AfterGAF Service Pricing in Irving

What you’ll pay depends on roof size, pitch, the condition of the decking underneath, and whether we’re repairing a targeted zone or replacing the whole system. Here are the ranges we quote for Irving work:
| Service | Irving Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Metal Roof Installation | $15,000 – $40,000 |
| Tile Roof Repair | $600 – $2,500 |
The biggest driver on a replacement is roof complexity: hips, valleys, dormers, and the number of layers we have to tear off. We give you a written price before any work starts, so the number you see on the estimate is the number on the invoice. Call (940) 204-5368 to schedule a free estimate; we’ll walk the roof with you and explain exactly what we’d do and why.

FAQs – GAF Construction in Irving
It depends on which GAF warranty was registered and whether the installation met GAF’s published requirements at the time of install. Irving adopted updated wind-load standards around 2019, and homes roofed before that often don’t meet the current nailing pattern GAF now requires for maximum wind coverage. We can inspect your existing roof, pull a shingle to check the fastening pattern, and tell you honestly what your warranty likely covers. Call (940) 204-5368 and we’ll schedule the inspection.
Clay soil movement doesn’t touch the shingles directly, but it moves the fascia, the rake boards, and the chimney, all of which can open gaps in the roof system over time. On Irving slab homes, we pay extra attention to step flashing at walls and chimney saddles, because the structure shifts seasonally and a flashing detail that’s tight in June can be pulling apart by January. We also account for the debris and dumpster placement issues described above, so we don’t add weight where the slab is already stressed.
Often, yes. If the hail damage is isolated to one or two slopes and the rest of the roof is sound, a targeted zone repair can buy you five or more years. We’ll match the shingle color as closely as GAF’s current line allows and make sure the repair ties into the undamaged field cleanly. We won’t push a full replacement unless the damage or the roof’s age makes it the honest call. Call (940) 204-5368 for a free inspection and a straight answer.
We specify StormGuard leak barrier on the eaves, in valleys, and around penetrations on every Irving installation. In a city that gets both heavy thunderstorms and hail, StormGuard’s adhesive backing seals around nails and prevents water from working its way into the deck if shingles blow off or fracture. For the field areas, standard GAF synthetic underlayment is fine, but skipping StormGuard at the critical zones is a false economy here.
For low-slope EverGuard systems, we start by locating the source of any tenting or wrinkling, typically over-torqued fastening plates that trap thermal expansion. We reset the fasteners to GAF’s spec, repair or patch the affected membrane with heat-welded EverGuard, and inspect the drainage to make sure ponding water isn’t compounding the problem. These are common repairs on the older apartment stock around Hospital District and north Irving. Call (940) 204-5368 and we’ll put together a written plan for your property.
