Why Pomona Residents Choose Us for GAF Service

Elmwood Contractors is a single-source general contractor, meaning we coordinate the full project under one roof and one point of accountability. That matters when a roof repair uncovers rotten decking or a fascia that needs sistering, because we don’t stop the job and hand you a second contractor. We handle it.

Nolan Shepherd runs our operations. He grew up in Fullerton’s Sunny Hills neighborhood, where houses built in the late ’60s taught him early which ones were going to have problems. He’s been running Elmwood for two decades now, and his framing is plumb the first time. We name the brands going into your home before the contract is signed, including which GAF shingle line and what underlayment. That’s how we’ve always worked in Pomona.

We’re an independent contractor, not manufacturer-affiliated or authorized. That means when a repair beats a tear-off, we say so. We spec genuine GAF shingles and accessories for field and ridge, but we’ll spec quality aftermarket flashing and vent boots where they outperform the OEM part. The right material in the right place. Everything else is just catching up to that decision.

Common GAF Construction Problems We Solve in Pomona

• Thermal cracking and granule loss on south- and west-facing Timberline slopes. Triple-digit Pomona summers bake the asphalt mat until shingles dry out and curl at the rake edges. We see this on nearly every 15-to-20-year-old Timberline roof in 91767 and 91769. Once the granules are gone and the mat is cracked, patching won’t hold. That’s a re-roof.
• Wind-lifted and creased shingles along ridges and hips after Santa Ana events. The winds here don’t just lift shingles; they crease them where the seal strip breaks and never re-adheres. On Pomona’s ranch tracts with low-pitch hips, this shows up as a row of shingles standing proud of the field. We replace the damage and check every seal strip on the ridge line.
• Dry-rotted decking and rotten fascia under aged Royal Sovereign 3-tab. Pomona’s few heavy winter storms push water past worn flashing into decking that’s been sun-brittle for years. The rot is often worse than the shingle wear suggests. We re-deck the bad runs rather than nail new shingles into sponge.
• Failed pipe boots, step flashing, and valley metal. On Pomona’s older bungalows, the leak shows up at the ceiling but the cause is almost always a boot or a valley, not the shingle field. We inspect these first. Seasonal water intrusion in Pomona is a flashing problem masquerading as a roof problem.
• Storm damage from wind-driven debris. Santa Ana winds throw tree branches and patio furniture into roofs across Pomona. We handle emergency board-up and tarping, then permanent GAF repairs once the wind dies down. Call (866) 253-8554 if you’re looking at a fresh puncture.

GAF Service in Pomona: What Local Conditions Mean for Your Equipment

Pomona’s average rainfall is only about 15 inches a year, so most roofs here fail from heat and wind aging rather than chronic wet. But here’s the thing: the handful of strong winter storms are when every neglected flashing detail leaks at once. A 1920s Craftsman bungalow in 91766 might sit bone-dry through eleven months of Southern California sun, then dump water through a rusted chimney flashing during one January storm. The roof didn’t suddenly fail. It failed years ago; the storm just revealed it.

That’s why we inspect boots and valleys on every Pomona estimate, not just shingle color. On a 1920s Craftsman bungalow off the 91766 side of town, we tore off a wind-creased Royal Sovereign 3-tab field and found soft decking and a rusted chimney flashing that had been leaking into the ceiling for seasons. We re-decked the bad runs, replaced the step and counter-flashing, and laid a new Timberline HDZ system with ridge vent. The homeowner finally stopped chasing the ceiling stain every winter.

Pomona’s housing stock runs heavy on pre-1940s wood-frame bungalows and 1950s-70s ranch tracts. That means pier-and-beam foundations with rot-prone subfloor framing, undersized 100A panels, and roofs that have been patched by three generations of handymen. When we quote GAF construction work here, we quote for what we’ll find under the shingles, not just the shingles themselves. Contractors who bid Pomona like it’s Claremont or La Verne lose money or cut corners. We bid for Pomona.

GAF Models & Products We Service in Pomona

We work on GAF Timberline HDZ, the architectural shingle that dominates Pomona’s re-roof market for good reason: it holds up to the sun better than 3-tab and carries GAF’s manufacturer warranty when installed to spec. We also service Timberline Natural Shadow, the classic Royal Sovereign 3-tab line (still on thousands of Pomona’s original ranch roofs), and GAF Liberty SBS self-adhered systems for low-slope sections on mid-century apartment buildings and carports.

Our parts approach is specific. We use genuine GAF shingles, underlayments, and accessory components for the field and ridge. For flashing and vent boots, we spec quality aftermarket parts where they outperform the OEM offering; a plain GAF pipe boot doesn’t beat a Perma-Boot on a 1960s Pomona ranch. We keep common Timberline HDZ colors and underlayment on hand locally, which means faster turnaround for Pomona repairs instead of waiting on a supply yard in Ontario, Riverside, or GAF repair in Montclair.
