CertainTeed Construction in Crestline, CA | Timberline Contractors
We install and repair San Bernardino CertainTeed service roofing and exterior systems across Crestline, and the one thing that separates our work here from valley work is elevation: every CertainTeed roof we touch at 4,500 to 5,000 feet has to answer to snow load, ice damming, and ember exposure before it answers to anything else. We’re an independent contractor, so our loyalty is to the roof on your cabin, not to a manufacturer’s marketing sheet. Call (866) 253-5808 for a straight read on what your CertainTeed roof needs up here.
Why Crestline Residents Choose Us for CertainTeed Service
We know CertainTeed’s product lines the way a mountain contractor should: by how they hold up under real conditions, not catalog photos. Landmark architectural shingles, Presidential Shake, NorthGate insulated siding, DiamondDeck underlayments. We’ve torn off enough failed CertainTeed installs in Crestline to know exactly where the product works and where the installer cut corners. Nelson Fung, our owner and general contractor, grew up watching his grandfather negotiate tile prices in Chinatown hardware stalls, then spent years swinging hammers across the LA basin before running Timberline. He’ll explain why one underlayment choice matters more than the shingle on top of it. We’re not manufacturer-authorized, and that matters: we install and repair CertainTeed systems because they work, not because a rep told us to push them.

Common CertainTeed Construction Problems We Solve in Crestline
- Seal-strip failure and wind-lifted tabs on Landmark shingles. Freeze-thaw cycling at this elevation works adhesive strips loose, especially on exposed gable ends facing the lake or the ridge. We see it most on 1990s and 2000s installs where the shingles never got a proper cold-weather seal. Repair means hand-sealing or replacing individual tabs before wind gets under them and starts a cascade.
- Ice damming at the eaves. Crestline snowmelt pools at the eave line on under-ventilated attics. If the original CertainTeed install didn’t include ice-and-water shield at the eaves, meltwater backs up under the shingles and leaks into the soffit and wall. This is the most common winter call we get in 92325, and the fix usually involves more than just the roof.
- Granule loss and algae streaking on north-facing slopes. Heavy snowpack sits on north-slope roofs longer, and pine needles trap moisture against the shingle surface. CertainTeed asphalt shingles shed granules faster under those conditions, and the resulting streaking isn’t just cosmetic. It accelerates shingle decay.
- Dead attic air over old cabin roof decks. We routinely find CertainTeed shingles installed over one or two layers of old three-tab, with no soffit venting and no ridge vent. The shingles cook from the underside in summer and trap snowmelt in winter. Life expectancy drops by a third or more on those roofs.
- Flashing failures where snowmelt pools. Older Crestline cabins have valleys and dormer intersections that were flashed for rain, not for the slow, persistent meltwater of a mountain winter. CertainTeed shingles perform fine, but the flashing around them fails, and we correct it at the source.
CertainTeed Service in Crestline: What Local Conditions Mean for Your Equipment
Crestline’s roughly 4,500 to 5,000-foot elevation means every CertainTeed roof here is sized for real snow load and ice damming. Details like eave ice-and-water shield and balanced intake/exhaust ventilation matter far more on a hillside off Highway 138 than they would on a valley roof at 1,000 feet. A roof that never sees ice can get away with a basic install. Yours can’t. The long-standing local knowledge among mountain contractors is that any hillside deck or addition in Crestline needs engineering for snow load and slope creep, and unpermitted cabin additions from decades past are common enough that we routinely build permit-legalization and as-built corrections into mountain remodels. That’s not a valley problem. It’s a Crestline problem, and it changes how we scope CertainTeed work from the first walkthrough.
CertainTeed Models & Products We Service in Crestline
We install and repair the CertainTeed lines that actually make sense for mountain construction: Landmark architectural shingles, including impact-rated Landmark IR for fire-hardening requirements; Presidential Shake and Presidential Solaris for luxury asphalt; NorthGate and CedarBoards insulated vinyl siding; and DiamondDeck underlayments and roof accessories. We use genuine CertainTeed accessories where they integrate with the shingle warranty system: underlayments, starter strips, ridge vent, hip-and-ridge. Where performance is equal, we use quality aftermarket flashing and ventilation. On a sound CertainTeed deck we repair rather than replace. Once shingles hit end-of-life on a snow-loaded mountain roof, patching just delays the inevitable tear-off. Our CertainTeed sales & service experience means we stock common accessories locally for fast Crestline turnaround instead of waiting on a valley distributor.

AfterCertainTeed Service Pricing in Crestline
What you pay depends on the pitch of your roof, the number of layers we’re tearing off, whether the deck needs replacement, and how much ice-and-water shield the eave detailing requires. Steep A-frame roofs cost more per square to work on than low-slope cabin roofs. Two layers of old shingles cost more to remove than one. Here are the ranges we quote across the CertainTeed in Highland and San Bernardino Mountains:
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Metal Roof Installation | $15,000 – $40,000 |
Every estimate includes a roof inspection, a written line-item scope, and a materials list that names the specific CertainTeed products going on your roof. No change orders disguised as surprises. Call (866) 253-5808 and we’ll schedule the walkthrough.

FAQs – CertainTeed Construction in Crestline
Yes, when installed to mountain spec: ice-and-water shield at the eaves, balanced attic ventilation, and proper fastening for the roof pitch. The shingle itself can handle the weight if the structure and deck beneath it are sound. Nelson Fung walks every Crestline roof deck before quoting, because a great shingle on a rotten deck is just a shingle waiting to slide. Call (866) 253-5808 for an inspection before the snow season starts.
That’s ice damming, and it’s the most common CertainTeed failure mode in Crestline. Meltwater backs up behind the frozen eave edge and seeps under the shingles. The fix is eave ice-and-water shield plus better attic ventilation. We’ve corrected this on dozens of mountain cabins in the 92325 zip, often without a full tear-off. Call (866) 253-5808 and we’ll tell you what your specific roof needs.
Usually yes, if the shingles still have service life and the deck is sound. We replace damaged tabs and flashing, hand-seal lifted edges, and correct ventilation. If the roof is past mid-life or the deck is spongy from snowmelt intrusion, repair becomes false economy. We’ll show you the evidence and let you decide. Estimates are free: (866) 253-5808.
Metal handles Crestline snow shed better than asphalt, especially on steep A-frame pitches where snow releases all at once. CertainTeed service in Muscoy and up here means metal lines that perform well, and we install them over proper snow-rated underlayment. The tradeoff is cost: metal runs $15,000 to $40,000 on most Crestline homes, against $8,000 to $20,000 for architectural asphalt. Call (866) 253-5808 and we’ll price both for your specific roof.
Yes. Crestline has decades of unpermitted cabin work, and we regularly build permit-legalization and as-built corrections into our scopes. If your CertainTeed roof or the deck under it was never properly permitted, we pull the permits, schedule the inspections, and bring the structure to current snow-load and fire-hardening code. Call (866) 253-5808 and we’ll start the process now.
