Owens Corning Construction in Pomona, CA

Owens Corning Construction in Pomona, CA | Alder Contractors

We provide independent Owens Corning service in Claremont and across Pomona, including roof installation, repair, and storm damage work, and we’ve done it long enough to know this city isn’t a single roofing market. A 1923 Craftsman near downtown needs a different hand than a 1987 tract home in north Pomona, and we plan each accordingly. If you need Owens Corning shingles installed, matched, or repaired, call (833) 467-7020 for a free estimate.

Why Pomona Residents Choose Us for Owens Corning Service

We’ve been installing Owens Corning shingle, underlayment, and accessory systems across Pomona’s split housing stock for years, and we also handle Owens Corning repair in Montclair – 1920s pier-and-beam bungalows in the 91766 core and 1980s tract roofs in the northern subdivisions. That range matters because each roof type fails differently here. Nelson Ibarra, our owner, grew up working construction across the Inland Empire and built Alder Contractors around one idea: name the real materials, fix the actual problem, and don’t sell a roof that isn’t needed. Pomona homeowners call us because we’ll tell them when a repair makes sense and when the shingle field is done. We’re an independent Owens Corning-specializing contractor, not a manufacturer-authorized dealer. Our credibility comes from the roofs we’ve repaired and replaced here, not a certificate on the wall.

We stock genuine Owens Corning shingles, starter, ridge cap, and underlayment for faster turnaround in Pomona, and we pair them with quality flashing rather than whatever’s cheapest at the supply yard. See our broader Owens Corning sales & service approach. Do it right the first time – the callback always costs more than the extra hour up front.

Common Owens Corning Construction Problems We Solve in Pomona

Different parts of Pomona stress Owens Corning roofs in different ways. Here’s what we see most often:

• Granule loss and cracking on Supreme three-tab shingles. Older pre-war bungalows in 91766 and 91767 often still carry original Supreme three-tabs. Intense San Gabriel Valley summers bake the sun-facing south and west slopes until the shingles lose granules, crack, and eventually leak at the original sparse nailing pattern.
• Wind-blown shingles on 1980s-90s tract roofs. North Pomona tract homes built with original-construction OC shingles lose ridge cap and gable rake shingles during Santa Ana wind events, especially where edge nailing was never upgraded from the original spec.
• Racked roof planes on pier-and-beam foundations. Expansive clay under Pomona’s historic core moves foundations seasonally. When a pier settles, the roof plane racks slightly, opening seams and stressing valley and step flashing faster than the shingle field itself wears.
• Brittle underlayment failure at penetrations and valleys. Decades of dry heat bake underlayment until it crumbles. The felt goes before the shingle does, so leaks show up mid-field rather than at the obvious edge – a confusing pattern until you know what to look for.
• Second-layer tear-offs on pre-war roofs. Many 91766 bungalows have a second layer of shingles over the original. That added weight and trapped heat accelerates granule loss, and tearing it back to decking reveals dry-rotted spots around old nail holes.

Owens Corning Service in Pomona: What Local Conditions Mean for Your Equipment

Here’s something you won’t hear from a roofing company that treats Pomona like any other LA County city: the pre-1940 bungalows around the downtown core sit on raised pier-and-beam foundations over expansive clay, and before we re-roof one we check that the roof planes are still square to each other. A sagging pier shows up as a racked roof plane, and new Owens Corning shingles laid over that will telegraph every seam. On a 1920s Craftsman near downtown in the 91766 core, we found original three-tab shingles over a brittle, sun-baked felt layer, and the north slope had racked slightly as the foundation settled into the clay. We leveled and re-flashed before laying Owens Corning Duration shingles with fresh underlayment and upgraded edge nailing, so the new roof sits on a stable deck instead of chasing the foundation’s movement. That check adds a step, but skipping it is how you get a new roof that looks wavy in six months.

Owens Corning Models & Products We Service in Pomona

We work on the Owens Corning lines most commonly found across Pomona’s housing stock. Oakridge laminated shingles show up frequently on mid-century and 1980s-90s tract homes, Duration TruDefinition architectural shingles are the go-to for re-roofs on historic-core bungalows, and Supreme three-tabs appear as the original or second layer on many pre-war roofs. The Berkshire Collection comes into play when a homeowner wants designer laminated shingles that visually match a Spanish Colonial or Craftsman exterior without fighting its character. Our approach: install genuine Owens Corning shingles where profile and exposure match what’s on the house, and pair them with OC’s own accessory line – underlayment, starter, ridge cap, flashing – rather than cheap substitutes.

FAQs – Owens Corning Construction in Pomona

My 1920s bungalow in 91766 has sloping floors and a roof that looks wavy – do I fix the foundation or the roof first?

The foundation comes first. On Pomona’s pre-war pier-and-beam bungalows, the roof plane racks when a pier settles into the expansive clay. Re-shingling over a racked deck telegraphs every seam and wastes the material. We inspect the foundation, level what’s needed, then re-roof – in that order. Call (833) 467-7020 and we’ll assess both before you spend a dollar.

Will an Owens Corning shingle roof hold up to Pomona’s 100°F-plus summers and Santa Ana winds?

Yes, with the right specification and installation. Duration TruDefinition shingles handle San Gabriel Valley heat well when paired with proper underlayment and upgraded edge nailing at ridges and rakes. The failure we see on Pomona tract roofs is almost always an original nailing pattern never upgraded for wind, not a shingle defect. Call (833) 467-7020 for an inspection.

Do I need a permit to re-roof my north Pomona tract home, and does the HOA get a say?

Yes, Pomona requires a re-roof permit, and if your tract home sits under an HOA, that HOA can restrict shingle color and sometimes profile. We pull permits and handle the paperwork, but you’ll want to check your HOA’s architectural guidelines before we finalize the shingle choice. Call (833) 467-7020 for help navigating both.

Can you match the existing shingles on my historic-core home instead of replacing the whole roof?

Often yes. If the field still has life and we can match the shingle profile, we repair and re-flash rather than push a full replacement. We’re also direct when a partial repair is throwing money at a roof that’s done. Call (833) 467-7020 and we’ll tell you which way it goes.

How long does an Owens Corning re-roof take on a pier-and-beam bungalow versus a tract house?

A straightforward tract re-roof in Pomona typically runs two to four days. A pier-and-beam bungalow runs longer – often four to seven days – because we check and level the foundation first, which is a separate step most tract roofs never need. Call (833) 467-7020 for a timeline on your specific roof.
