This page is for Santa Clarita homeowners who already own an Owens Corning roof, or are considering one, and want straight answers about replacement costs, failure patterns, and what a proper job looks like from tear-off to final inspection.

How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes good shingles. But after 15 to 20 years in Santa Clarita’s dry heat and wind, every shingle line shows its age in specific ways. Here’s what we find when we tear off Owens Corning roofs in Valencia, Canyon Country, Saugus, and Newhall:

• Duration Series granule loss and balding. The Duration line (including Duration STORM and Duration Flex) uses a heavier granule embedment than older Owens Corning lines, but after a decade of Santa Clarita sun, we regularly see granule wash-off at the shingle edges. The fiberglass mat underneath starts to show, and that’s the signal the shingle’s UV protection is gone. Replacement is the honest fix here, and we’ll document the balding with photos before we recommend anything.
• Oakridge edge curling at the eaves. Oakridge shingles curl upward at the corners when attic ventilation is poor, and that’s common in older Santa Clarita tract homes with undersized ridge vents. The shingle isn’t always the root cause. We check ventilation first. If we replace the roof without fixing the airflow, the new shingles do the same thing in five years, and that’s a waste of your money.
• Deck rot under valley metal. Owens Corning roofs with open metal valleys concentrate runoff, and in Santa Clarita’s occasional heavy winter rain, we’ve found decking rot where valley flashing was installed over a single layer of underlayment instead of two. You can’t see this from the ground. We find it during tear-off, and that’s exactly why we write decking replacement into the estimate as a line item with a per-sheet price before we start.
• Hip and ridge cap cracking on Duration STORM. The ridge cap takes the brunt of Santa Clarita’s wind, especially up in Stevenson Ranch and Castaic where gusts funnel through the hills. We replace cracked caps with matching Owens Corning hip and ridge shingles, and we hand-seal the edges rather than relying on the factory adhesive strip alone. The factory adhesive softens in high heat and re-seals but leaves gaps in winter, which is when wind gets under the cap and rips it off.
• Flashing failures around chimneys and skylights. This isn’t unique to Owens Corning, but it’s the most common replacement-before-its-time trigger we see. Flashing, the metal strips that seal joints around chimneys and vents, corrodes where Santa Clarita’s alkaline soil dust settles and holds moisture against the metal. We use 26-gauge galvanized or .019-inch painted steel, never the cheap builder-grade flashing that was likely on the original roof, and we step-flash every course, not just caulk over the gap.

Our Owens Corning Roof Replacement Process

Every Owens Corning roof we replace in Santa Clarita follows the same sequence. No surprises, no shortcuts, and the price never changes from the written estimate unless you approve a change order yourself.

1. 1
   Call and book. A live person answers at (661) 219-7793, takes your address and the basics of what you’re seeing, and schedules an estimate at a time that works for you.
2. 2
   On-site inspection and written estimate. We walk the roof, check the decking, flashing, and ventilation, and then hand you a written line-item price. Every estimate we hand you is one we’d be comfortable signing twice.
3. 3
   Material selection. We go over your Owens Corning options, from Oakridge entry-level to Duration premium lines, explain the price difference honestly, and place the order. We also work with GAF and CertainTeed if you want a comparison before committing.
4. 4
   Tear-off and deck inspection. We strip the old roof to the deck, find any rotted sheets, and photograph everything before and after. Decking replacement is priced per sheet in your initial estimate so there are no mystery charges.
5. 5
   Installation and cleanup. New underlayment, new flashing, new Owens Corning shingles, magnetic nail sweep, and full cleanup. We take photos of the finished roof and send you a digital invoice by text.
6. 6
   Guarantee. Every replacement carries our workmanship coverage, and your Owens Corning shingles carry their manufacturer’s warranty. We register the warranty paperwork for you.

What Owens Corning Roof Replacement Costs in Santa Clarita

Here’s what we’re seeing on current Santa Clarita Owens Corning replacement jobs. These are real ranges based on typical single-family homes in the 1,600 to 2,800 square foot range:

• Oakridge tear-off and replacement: $14,000 – $18,500
• Duration tear-off and replacement: $16,500 – $22,000
• Duration STORM or Duration Flex: $19,000 – $26,000
• Decking replacement (per 4×8 sheet): $120 – $160, when needed
• Full flashing replacement (chimneys, valleys, penetrations): $800 – $2,400 depending on roof complexity

What moves the price: roof pitch (steeper costs more), number of layers being torn off, decking condition, how many valleys and penetrations you have, and which shingle line you pick. Higher-end Duration lines carry a better wind rating, which matters if you’re up in the windier parts of Stevenson Ranch or Castaic. Call (661) 219-7793 for an exact quote on your roof. Estimates are free and written.
