Owens Corning Roofing in Camarillo, CA | Mercer Roofing Co Thousand Oaks
We’re Mercer Roofing Co Thousand Oaks, an independent Owens Corning service provider working throughout Camarillo. The quick answer: we replace, repair, and match Owens Corning shingle roofs here, and the thing that separates our work is knowing how Santa Ana wind cycling behaves in Camarillo Heights versus the newer Mission Oaks tracts. That local read changes how we fasten, flash, and vent every Owens Corning roof we touch. Call (805) 309-3314 for a written estimate before any work starts.
Why Camarillo Residents Choose Us for Owens Corning Service
We’ve been putting Owens Corning shingles on Ventura County roofs since well before the current model lines existed. Our crews know Duration, Oakridge, Trudefinition, and Supreme the way a mechanic knows a specific engine family: what fails, where it fails first, and whether a repair makes sense or you’re just buying time. Grant Whitlock, our owner, started roofing as a teenager patching a neighbor’s garage after a wet winter in Los Angeles, then came up through the construction technology program at Los Angeles Trade-Technical College. He teaches our techs to read a roof deck before touching anything, so you never get guesswork dressed up as a fix.
Because we’re independent, not a manufacturer program, we answer to you, not a marketing department. We use genuine Owens Corning accessories where color and profile match matters, and we’ll tell you plainly when an aftermarket shingle will outlast what’s left on your roof. You get the written price up front, the tech’s name and photo before arrival, and a photo ID badge at the door. That’s the Threshold Standard we hold every visit to.

Common Owens Corning Roofing Problems We Solve in Camarillo
Here’s what our Roof Repair - Camarillo crews actually find on Owens Corning roofs, week after week:
- Santa Ana wind uplift on Duration roofs. When starter strip adhesion breaks down along the eave, a sustained north wind gets under the first course and lifts tabs. In Camarillo, this shows up most often on east-facing slopes above the older ranch tracts. We reset the starter with six nails per shingle and add edge metal where flutter keeps tearing underlayment.
- UV-cooked granule loss on older Supreme shingles. Camarillo’s sun is relentless, and Supreme was never built for this much UV. The surface sheds granules, leaving dark patches that look wet but are actually cooked asphalt. Once that happens, the shingle’s protection is gone. We’ll show you photos before recommending repair or replacement.
- Curling and cupping on Oakridge roofs with weak attic ventilation. Camarillo’s mild winters mean many older homes were built with minimal venting because rain wasn’t the worry. But trapped heat bakes the underside of Oakridge shingles, and the edges curl. The fix is often ventilation first, then shingle replacement.
- Nail pops and backing cracks on Trudefinition after thermal cycling. Hot Camarillo days followed by sharp cool nights, especially in fall, expand and contract shingle matting repeatedly. Nails back out, and the fiberglass backing cracks at stress points. We catch these before the next Santa Ana turns a popped nail into a torn shingle and a leak.
- Failed underlayment beneath intact shingles in Camarillo Heights. This one catches people off guard. The shingle surface looks fine, but the original 1960s felt underlayment beneath has torn at the eave line from decades of wind flutter. Water gets in through the tear, not the shingles. A repair here means stripping courses, replacing the felt section, and re-fastening properly.
Owens Corning Service in Camarillo: What Local Conditions Mean for Your Equipment
Here’s something you won’t read in an Owens Corning brochure. In Camarillo Heights, the original 1960s wood shake roofs were commonly decked with skip sheathing, which means gaps between the boards. When we overlay Owens Corning Duration shingles on those homes, we have to replace missing or rotted board gaps first. If we don’t, the shingles have no solid base at those gaps, and the first hard Santa Ana wind tears them loose at exactly those weak points. A newer Mission Oaks tract home almost never needs that step because the decking is solid OSB from day one. That one difference changes the cost, the time, and whether a contractor is actually fixing your roof or just covering it. We’d rather show you the gap and fix it than pretend it isn’t there. A roof should protect you quietly – if you’re thinking about it, something’s wrong.
Our crews handle full shingle replacement, roof decking replacement, and tile underlayment replacement across Camarillo. See our broader Owens Corning sales & service page for how we approach this brand county-wide.
Owens Corning Models & Products We Service in Camarillo
We service all the Owens Corning lines you’re likely to have on a Camarillo roof. Duration is the most common on newer re-roofs in Mission Oaks and Springville, so we carry matching ridge cap, starter shingles, and hip-and-ridge stock locally for fast turns. Oakridge still sits on many 1980s and 1990s ranch homes. Trudefinition shows up on mid-2000s builds. Supreme is what we find on older budget re-roofs, and those are the roofs most likely to need full replacement rather than patchwork.
Our rule on parts: if the roof is young and the color match matters, we use genuine Owens Corning accessories. If the line is discontinued or the surrounding shingles are too far gone to match anyway, we’ll recommend a better-grade aftermarket shingle and tell you why it will outlast what remains. We replace before we patch when the decking or underlayment has already failed. There’s no point saving a shingle course sitting on rotten wood.

FAQs – Owens Corning Roofing in Camarillo
Yes. Duration shingles use a fabric-reinforced nailing strip that holds fasteners better than older fiberglass mat. The weak point isn’t the shingle itself; it’s the starter strip adhesion at the eave and the fastener count along the edges. In Camarillo, we see wind damage on Duration roofs most often where the starter strip was installed with too few nails or has aged out at the glue line. Call (805) 309-3314 if you’re seeing lifted tabs, and we’ll tell you whether it’s a re-nailing or a tear-down.
That’s granule loss, usually UV-accelerated on older Supreme shingles. Camarillo’s summer sun is strong enough to degrade asphalt faster than the manufacturer’s typical wear estimate. Once the granules are gone, the asphalt underlay is exposed and dries out into bare patches that look wet but aren’t. At that point the shingle has lost its weather protection. We’ll inspect and tell you whether it’s isolated or widespread, and whether repair or replacement makes sense.
Sometimes, and only if the line is still current. For newer Duration or Oakridge roofs, we can order matching Owens Corning shingle bundles. For discontinued Supreme or Trudefinition colors, a true match is unlikely because the original batch has faded and the line is out of production. We’ll show you the closest option and let you decide before we order anything. Call (805) 309-3314 for an honest read on your roof’s color situation.
No. A properly nailed and sealed ridge cap should not lift. When it does, the usual cause is either nail fatigue from repeated thermal cycling or the cap was never sealed properly at the factory. In Camarillo, we see this on older Oakridge and Trudefinition roofs whose ridge caps have been cooked and cooled for 15 or 20 years. A lifted ridge cap is an open seam for water to enter, and it needs repair before the next heavy dew or rain. Call (805) 309-3314 and we’ll get it resealed or replaced.
Yes, but not necessarily the shingles. If the shingles are still sound, we strip them back section by section, replace the rotten decking board, relay the same shingles where possible, and only replace shingles that are damaged during removal. The decking is structural; rotted wood will fail under foot traffic during the next inspection or storm. In Camarillo Heights, we do this often with skip-sheathed 1960s decks. Call (805) 309-3314 for a written quote on the decking section, not a full re-roof.
