How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes good roofing products, but like every manufacturer, certain lines have patterns we see over and over across Pasadena rooftops. Here’s what we find, why it happens, and how we address it when we replace the roof.

• Duration Series granule loss and thermal cracking. The Duration shingle is a solid architectural product, but on Pasadena roofs with full western exposure, the asphalt layer can dry out faster than expected, leading to granule loss and hairline surface cracking by year 12 or 13. When we replace these, we check attic ventilation first, because inadequate airflow is often the real reason the shingles aged prematurely. New shingles over a hot attic repeat the same failure.
• Oakridge Series curling at the eaves. We see curling on Oakridge shingles most often on the south-facing eaves where Pasadena’s afternoon sun beats hardest. The cause is usually trapped moisture in the shingle’s fiberglass mat, which expands and contracts through our hot days and cool evenings. Our fix is not just new shingles – we inspect and often replace damaged fascia and add edge ventilation before installing the replacement roof.
• Supreme 3-tab delamination on low-slope Pasadena roofs. On older homes near Bungalow Heaven, we frequently find Supreme 3-tab shingles separating at the tabs. This happens because 3-tabs are thinner, and on low-slope roofs, water can wick upward under the tabs. The correct fix is not another 3-tab – it’s an architectural line like Duration or CertainTeed Landmark, paired with proper underlayment for the slope.
• Decking rot beneath failed Owens Corning shingles. In Pasadena’s older neighborhoods, the roof deck is often original to a 1920s or 1930s home. When Owens Corning shingles fail along flashing points, water sits against that old wood. By the time we strip the roof, we often find rot at the chimney or valley transitions. We quote decking replacement by the sheet and always photograph what we find so you see exactly what we’re asking you to pay for.
• Flashing failures at Pasadena chimney transitions. Owens Corning shingles rarely fail first – the flashing does. On homes with masonry chimneys, we commonly see the step flashing rusted through or the counterflashing separated, which lets water travel behind the shingles. A proper replacement means pulling back the shingle courses, replacing flashing with new metal, and sealing with compatible mastics. Skipping this step on a brand new Owens Corning roof is how leaks happen six months after replacement.

Our Owens Corning Roof Replacement Process

1. 1
   You call, a person answers. When you call (626) 657-5397, you talk to a live human, not a voicemail tree. We schedule a walkthrough that fits your calendar, including weekends if needed.
2. 2
   Inspection walk with you. We walk the roof, check the decking, flashing, and ventilation, and listen to any concerns you have. Erik Lindgren or a senior tech takes notes the whole time. You’ll know what we see, because we show you photos during the walk.
3. 3
   Written line-item estimate. Before any roof replacement, we give you a written price for everything: tear-off, dump fees, decking repair per sheet, underlayment, shingles, flashing, vents, and cleanup. Nothing changes unless you ask for a change, and you’ll approve that in writing too.
4. 4
   Tear-off and prep. We cover floors and landscaping, use shoe covers and drop cloths through any interior path, and coordinate door schedules if you have kids or pets inside. Every tear-off includes magnetic sweeps for nails at the end of each day.
5. 5
   Installation. We install the Owens Corning line you selected, using the manufacturer’s recommended fastening and underlayment standards. If your roof deck has issues, we document them and bring in the fix before any shingles go down.
6. 6
   Cleanup, photo, and Done Right Promise. Before our crew pulls away, we photograph the completed cleanup and review the work with you. Every Owens Corning roof replacement we install is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right.

What Owens Corning Roof Replacement Costs in Pasadena

Every roof is different, but here’s where Owens Corning replacement pricing lands in Pasadena, based on the jobs we do most often:

• 1,500 sq ft single-story with Duration shingles: $11,000 to $15,500, depending on decking condition and tear-off complexity.
• 2,000 sq ft two-story with Oakridge or Duration: $14,500 to $19,000, including flashing replacement at all penetrations.
• Larger Pasadena homes with premium Owens Corning lines: $19,000 to $26,000, with decking repair quoted per sheet if rot is present.
• Full tear-off with decking replacement: Add $75 to $110 per sheet for OSB or plywood replacement, quoted in writing before any work starts.

What moves the price most is the condition of the decking beneath the old shingles and whether the roof has steep pitches, multiple valleys, or masonry chimneys. The written estimate we give you at the start is the price you pay. No surprise adjustments after the tear-off unless you approve a change and sign off on it.
