Owens Corning Construction in Highland, CA | Timberline Contractors
We provide independent Owens Corning roof installation and repair across Highland’s valley-floor and foothill homes, from 1970s tract houses to hillside customs. What separates our Owens Corning work in Highland is that we plan every system around two local realities: wildfire defensibility under WUI code, and the way foothill lots shed stormwater downhill. Call (866) 253-5808 for a free estimate on your Owens Corning roof.
Why Highland Residents Choose Us for Owens Corning Service
Our crews have put Owens Corning shingles on Highland roofs through every season the San Bernardino foothills can throw, and that repetition teaches you things the product sheet doesn’t. We know how Duration holds its seal strip on a ridge-exposed street during a Santa Ana, and we know which attic venting makes sense on a 1980s tract home that was built with almost none. Nelson Fung, owner and general contractor at Timberline Contractors, started this company with the belief that a roof is only as good as the substrate under it and the flashing around it, no matter whose shingle is on top. We’re an independent contractor: not authorized, sponsored, or backed by Owens Corning. We simply prefer their systems where they fit, and we’ve spent years learning which profiles suit Highland’s conditions. As we see it, the roofer matters more than the brand, but pairing a roofer who actually knows Owens Corning sales & service with a shingle line suited to the Inland Empire is the smart combination.

Common Owens Corning Construction Problems We Solve in Highland
- Seal-strip failure and tab uplift at ridges and hips after Santa Ana events. Highland’s foothill-exposed roofs catch wind that valley homes never feel. Owens Corning shingles rely on a thermal seal strip, and when the adhesive is compromised by heat cycles or age, wind-driven uplift peels the tabs. We see this most on the upslope-facing ridge lines of homes climbing into the foothills.
- Premature granule loss and thermal cracking from unventilated attic heat in 1970s-90s tract homes. The valley floor of Highland has hundreds of tract homes built with minimal or no intake venting. Attic temperatures spike over 140 degrees in July, cooking shingles from below. Granule loss accelerates and the shingle matte becomes brittle, leading to cracks that open up during winter rain.
- Ember entry and non-Class-A underlayment on older Owens Corning assemblies predating current WUI expectations. Highland sits in a Foothill Zone where defensible-space and fire-resistant material rules have tightened. Homes that got a bargain tear-off fifteen years ago often have underlayment that wouldn’t pass today. During a dry Santa Ana, embers find those gaps at the eave and the assembly becomes a liability.
- Deck and flashing failure where roof planes tie into additions and ADU conversions. Highland’s housing stock is thick with room additions, garage conversions, and now ADUs. The transition between the original roof and the new structure is where we find soft sheathing and failed step flashing, usually discovered only after tear-off.
- Fascia rot and eave damage where foothill lot runoff concentrates. On hillside lots, the upslope eave catches water when the driveway or retaining wall above directs runoff toward the house. Combined with clogged gutters, this rots fascia boards and the underlying rafter tails, which compromises the overall roof system before the shingles fail.
Owens Corning Service in Highland: What Local Conditions Mean for Your Equipment
Highland sits at the base of the San Bernardino Mountains, where Owens Corning in San Bernardino foothill lots shed stormwater downslope during winter storms. That simple fact changes roof work in a way flat-lot Inland Empire cities never deal with. When we install an Owens Corning system on a hillside home, we are not just nailing shingles and walking away. We are checking how water from above the roofline moves toward the eaves, because the upslope fascia is the most rot-prone board on the whole structure. On one hillside home climbing into the foothills off the base of the San Bernardino Mountains, our crew tore off a wind-fatigued Owens Corning Oakridge roof where the ridge caps had lifted after a Santa Ana event and the fascia below the upslope eave was soft from runoff. We replaced the rotted sheathing and fascia, added proper intake and ridge venting, and reinstalled an Owens Corning Duration system with ember-resistant venting to meet the WUI expectations the address triggers. That is what an Owens Corning install in Highland has to account for, and it’s a detail you won’t get from a roofer who only works flat-lot valley subdivisions.
Owens Corning Models & Products We Service in Highland
We install and repair the full Owens Corning residential lineup, including Oakridge architectural shingles, Duration premium architectural shingles, and Supreme and WeatherGuard 3-tab shingles on older Highland and Owens Corning repair in Muscoy tract homes that still wear them. For Title 24 cool-roof compliance on remodels and ADUs, we stock and install Owens Corning Duration Cool shingles which meet California’s solar reflectance requirements. Our parts approach is system-consistent: we use Owens Corning ridge caps, starter strips, and underlayment so the entire assembly matches, rather than mixing aftermarket components from different manufacturers. We keep standard Highland-moved shingle profiles and accessory components in local inventory for faster turnarounds on repair calls, which means less waiting when a Santa Ana tears a ridge cap off in October.

AfterOwens Corning Service Pricing in Highland
Roof pricing in Highland follows the same logic as anywhere else in the Inland Empire, with two local twists: foothill lots add scaffolding and sometimes drainage or retaining-wall coordination, and WUI compliance can add cost for fire-resistant underlayment or ember-resistant venting. Below are the ranges we see most often on Owens Corning work in Highland. A free estimate from us includes a physical inspection of the deck, flashing, and attic venting so you’re not paying for surprises after tear-off.
| Service | Price Range |
|---|---|
| Roof Replacement (Owens Corning architectural) | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Metal Roof Installation | $15,000 – $40,000 |
| Tile Roof Repair | $600 – $2,500 |
What drives the spread is square footage, pitch, deck condition, and whether the home triggers WUI requirements. Steep hillside roofs cost more to work on, full stop. Call (866) 253-5808 for a written line-item quote, not a number pulled from a square-footage chart.

FAQs – Owens Corning Construction in Highland
No. Timberline Contractors is an independent general contractor with deep Owens Corning product experience, but we are not authorized, sponsored, or backed by Owens Corning. That independence is useful: we tell you what’s actually failing, not what the manufacturer’s representative wants us to sell.
On a Highland hillside lot, the roof is only as good as the drainage above it. Water shedding off the slope concentrates at the upslope eave and rots fascia, rafter tails, and eventually decking if gutters and drainage aren’t handled. We inspect the slope above the house and check for negative grading before we quote any roof work, because a new Owens Corning roof over a deck that keeps getting soaked is a waste of money.
Yes. We use Owens Corning shingles and matching Owens Corning ridge caps, starter strips, and underlayment so the repaired section performs like the original and meets the same fire ratings. If the roof is beyond a repair patch, we’ll tell you honestly. Patching over a failing deck or mis-matched venting just means you’ll be calling us again in two seasons.
Most tear-off and replacement jobs on Highland homes take three to five working days for a typical 2,000-2,500 square foot roof. Steep foothill lots with scaffolding add a day or two. Emergency repairs, like a wind-lifted ridge cap after a Santa Ana, can usually be addressed within a business day once we can access the slope. Call (866) 253-5808 with your address and we’ll give you a realistic timeline, not a salesman’s promise.
Plan on $8,000 to $20,000 for a full Owens Corning architectural shingle replacement in Highland and Owens Corning in Redlands, depending on square footage, pitch, WUI compliance requirements, and deck condition. Homes on steep foothill lots with deck replacement and ember-resistant venting run toward the top of that range. Call (866) 253-5808 to schedule a free inspection and get an exact number.
