GAF Roofing in Pomona, CA | Barnwood Roofing
We provide independent GAF roofing service across Pomona, covering Timberline shingle repairs, full re-roofs, and flashing work on the city’s mix of century-old bungalows and mid-century tract homes. We also offer Roof Repair – Pomona for homes throughout the area. What sets our GAF work apart here is that we understand how Santa Ana winds and months of direct sun hit the tiles and shingles on Pomona roofs differently than roofs ten miles away. If you need an honest assessment of your GAF roof, call (855) 382-1073 and we’ll tell you what it actually needs.
As an independent contractor and not a GAF-authorized installer, our credibility comes from years of hands-on GAF sales & service work on Pomona’s aged clay tile, wood shake, and composition shingle roofs. We know GAF’s product families well enough to tell you exactly where each one holds up and where it fails under Pomona’s UV and wind exposure. That matters more than a certificate on the wall.
Why Pomona Residents Choose Us for GAF Service
Most roofing companies in Pomona know one or two shingle brands. We work with seven: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means when we recommend a GAF product on your home, it’s because it fits your roof and your budget, not because it’s the only thing we stock. And when a repair will hold for another five years, we’ll tell you that too. Fair warning: if a full replacement is what your roof needs, we won’t soften that either.
Ruben Calloway, our owner, learned roofing through Chaffey College’s construction technology program and spent years working roofs across the Inland Empire before starting Barnwood Roofing. He grew up near the base of the Jurupa Hills in Fontana, where summer heat taught him early what a bad roof does to a family. His approach to every Pomona job is the same: “Tell me what the roof actually needs – then we’ll talk about what it costs.”
Our Pomona service area coverage means we’re already working in your ZIP code weekly, not driving in from another county for a one-off job. We know which Pomona neighborhoods carry original clay tile, which tracts have skip-sheathing under their composition shingles, and which slopes take the worst Santa Ana beating. That local knowledge shapes every GAF repair and replacement we quote.

Common GAF Roofing Problems We Solve in Pomona
- Granule loss and seal-strip lifting on Timberline HDZ. On west- and south-facing slopes of Pomona tract homes, Timberline HDZ shingles take relentless afternoon sun and repeated Santa Ana wind events. We regularly see granule loss that leaves bare asphalt showing, plus seal strips that release along the shingle edges. The fix is often a targeted replacement of the damaged courses rather than a full re-roof, though we’ll tell you honestly when the damage has spread too far for that to make sense.
- Shingle cracking over skip-sheathing. When GAF shingles go over older decks with gaps between boards, the shingle courses can telegraph those voids and crack along the sag lines. On Pomona homes built before the 1960s, skip-sheathing is common, and a re-roof without re-sheeting the deck first means the new GAF shingles start failing within a few seasons. We include deck inspection and re-sheeting in our quotes when it’s needed.
- GAF Liberty membrane seam failures on low-slope sections. Pomona homes with porch roofs, additions, or carport sections under a low slope often have GAF Liberty self-adhered membrane. When ponding meets a poorly primed lap at the seam or perimeter, winter rain gets underneath. We see this on flat sections across 91767 and 91768. Repairing the seam properly beats replacing the whole membrane most of the time.
- Dried and fractured GAF underlayment on 1990s-2000s re-roofs. Underlayment doesn’t last as long as the shingles above it, especially in Pomona heat. We’ve opened up roofs where the felt under the shingle layer has dried and cracked, letting winter rain reach the deck while the shingles still look fine from the ground. If your Pomona home was re-roofed between 1995 and 2010, this is a real possibility.
- Flashing failures at chimneys, vents, and valleys. Santa Ana winds work flashing loose over time, and Pomona’s older homes have more chimneys and more transitions than newer builds. A leak at the chimney flashing is often repairable without touching the GAF shingle field at all. We’ll always check the flashing before we talk about the shingles.
GAF Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona’s older Craftsman and Spanish Colonial Revival homes near downtown often carry original clay tile laid over skip-sheathing with failing felt, so a GAF shingle re-roof or a leak repair on those homes means pulling and salvaging brittle tile that cracks if you handle it carelessly. That salvage-and-reinstall step is far more common here than the straightforward composition re-roofs we see on the mid-century tracts. On a 1920s Spanish Colonial bungalow in the 91766 area near downtown Pomona, we traced a winter leak to failed felt under original clay tile that had been laid over skip-sheathing decades ago. Our crew carefully pulled and salvaged the brittle tile, replaced the rotted decking and underlayment, and set the tile back in place, then repaired the compromised flashing at the chimney that had started the whole problem. The homeowner kept their original tile and stopped the leak without a full tile replacement. That kind of work is part of what GAF service in Pomona actually means: you’re not always working on a clean composition shingle roof. Sometimes you’re preserving a hundred-year-old tile profile while making the system underneath it watertight again.
GAF Models & Products We Service in Pomona
We install and repair GAF Timberline HDZ and Timberline UHDZ architectural shingles, Royal Sovereign 3-tab shingles, and GAF Liberty self-adhered low-slope membrane. We stock common Timberline colors locally so most Pomona repairs don’t wait on a supplier order. For flashing and vent boots, we use quality aftermarket parts where they’re equal or better than GAF’s catalog. Genuine GAF shingles, underlayments, and accessories go on every repair and replacement so the system performs the way GAF designed it to. We won’t put a mismatched aftermarket shingle on your GAF roof, and we won’t tell you it’s the same thing when it isn’t.

AfterGAF Service Pricing in Pomona
What you’ll pay depends on what’s actually wrong. A flashing repair at a chimney or valley typically runs from a few hundred dollars. A partial shingle replacement on a Timberline HDZ roof, replacing a few damaged courses, usually falls in the $400 to $900 range depending on access and slope. A full GAF Timberline re-roof on a typical Pomona tract home, including new underlayment, runs roughly $12,000 to $22,000 depending on square footage and whether the deck needs re-sheeting. If we’re pulling and salvaging clay tile on an older home near downtown, that adds labor. Every quote we give is a written line-item estimate, and we’ll walk you through what’s essential versus what can wait. Call (855) 382-1073 and we’ll schedule a free estimate and give you exact numbers for your roof.

FAQs – GAF Roofing in Pomona
No, not when the existing deck is skip-sheathing or showing soft spots. On Pomona homes with original board decks, shingles installed without re-sheeting will telegraph the deck voids and crack along the sag lines within a few seasons. We’ll inspect the deck and tell you if re-sheeting is required before we install any GAF shingles. Call (855) 382-1073 if you want us to check your deck before you commit to a re-roof.
Yes, in most cases. We stock common GAF Timberline HDZ colors locally in Pomona, and for older or discontinued colors we can often source a close match through GAF’s distribution network. A repaired section will weather to blend in over time. If your shingles are too faded for a clean match, we’ll tell you before we start, not after. Call (855) 382-1073 and we’ll check your shingle color against what’s available.
Because the underlayment is probably failing. Shingles can look intact from the ground while the felt underneath has dried and cracked from years of Pomona summer heat. When winter rain arrives, water gets past the shingle layer, hits the fractured underlayment, and reaches the deck. We find this on 1990s and 2000s re-roofs all over Pomona. The fix is usually a targeted underlayment replacement rather than a full re-roof. Call (855) 382-1073 to schedule an inspection.
Yes, and we see it most on west- and south-facing slopes of Pomona tract homes. Repeated wind events lift shingle edges and break the seal strips, which then let the next wind get under the shingle and lift it further. Over time this causes granule loss and, in worst cases, shingles blowing off entirely. Certain Pomona neighborhoods catch more of this than others. If you’ve noticed granules in your gutters after a wind event, call (855) 382-1073 and we’ll check the slope.
Usually, yes. GAF Liberty membrane failures on low-slope porch and addition roofs are often a seam or perimeter lap problem that can be repaired without replacing the whole membrane. We’ll inspect the seams and primers before recommending anything bigger. Call (855) 382-1073 for a free estimate on your flat section.
