Owens Corning Platinum Preferred roofing.

Only the top 1% of Owens Corning roofers earn Platinum Preferred status — Owens Corning's top contractor rank. DeHart installs under Owens Corning Platinum Preferred through parent company Econo Roofing, which holds the registration under the same CSLB #749551. Here is what that means for your shingles, your warranty (the written promise that covers your roof), and your decades-out coverage.

What OC Platinum Preferred means

Owens Corning runs three contractor tiers (ranks). Platinum Preferred sits at the top. Only about 1% of OC contractors nationally hold it. That makes it rarer than GAF Master Elite, which about 2% hold.

To earn and keep Platinum Preferred status, a contractor must clear five gates each year:

  • State licensing. Current and valid in California.
  • Financial review. Independent verification of contractor financial stability.
  • Insurance. Verified general liability and workers' compensation coverage.
  • Customer reviews. Owens Corning audits real customer feedback — a falling reputation costs the badge.
  • Install quality. Documented track record of code-compliant installations to OC specifications.

OC reviews these qualifications annually. Contractors who fall short lose the badge. Platinum Preferred status is held by Econo Roofing, DeHart's parent company, through continuous training and a clean install record — under the same CSLB #749551. Every DeHart install is registered under it.

Owens Corning warranty tiers

Platinum Preferred status unlocks warranty coverage that standard contractors cannot offer. Owens Corning has three main tiers:

  • System Protection Limited Warranty. Standard contractors only. Materials coverage at the manufacturer's basic terms. Labor not backed by OC.
  • Preferred Protection Limited Warranty. OC Preferred contractors only (the mid-tier program). Stronger material terms and limited labor coverage backed by OC.
  • Platinum Protection Limited Warranty. Available from OC Platinum Preferred contractors only. This is Owens Corning's strongest warranty. Coverage stacks across three layers:
    • Materials. Up to 50 years of OC manufacturer coverage on the shingle system.
    • Workmanship. 25 years of labor coverage backed by Owens Corning.
    • No proration. Full coverage for the first 10 years. (Proration is the gradual write-down of payouts most warranties use; here, there is none for 10 years.)

Standard roofers cover shingles only. If the installation fails, you pay for the labor. With Platinum Protection, OC covers labor for 25 years. That coverage is backed by a Fortune 500 company, not just your contractor.

Central Valley climate benefits

The Central Valley gets summer heat over 100 degrees, strong delta breezes, and intense UV all year. The OC Duration line is engineered for it:

  • SureNail Technology. A patented strip of reinforced fabric across the nailing zone (the band where nails go in). It strengthens nail pull-through, which is the main failure point in high-wind events. This backs the 130 mph wind warranty.
  • StreakGuard algae resistance. 10 years of coverage against black algae streaking. This staining shows up most on north-facing slopes in irrigation-humid farm communities.
  • Class A fire resistance. The highest rating available — critical during California wildfire season.
  • Cool-rated products. Duration Cool and Premium Cool reflect more solar energy. That reflection is required for California Title 24 compliance (the state energy code) in Climate Zone 12. Both pass code.
  • Color hold. OC's color technology holds its tone better than most asphalt lines under 15-20 years of UV (sun) exposure. We see it on jobs we’ve come back to for repairs. The color still matches the original year-one finish.

How OC Platinum compares to GAF Master Elite

Both are top-tier manufacturer certifications. DeHart holds both. The differences matter when picking which system goes on your roof:

  • OC Platinum Preferred is rarer (~1% of OC contractors vs ~2% for GAF Master Elite).
  • GAF Golden Pledge covers tear-off cost if the roof fails. (Tear-off is stripping and hauling away the old roof.) OC Platinum does not include that line item.
  • OC Platinum Protection includes no proration for the first 10 years, so payouts are not written down over that time. GAF Golden Pledge is structured differently.
  • Color hold: OC Duration holds color slightly better long-term; GAF Timberline has the wider color range up front.
  • Algae: GAF StainGuard Plus carries 25 years of coverage. OC StreakGuard carries 10. If your roof has heavy shade, GAF has the edge here.

Frequently asked questions

What does Owens Corning Platinum Preferred mean?
Platinum Preferred is Owens Corning's top contractor tier. Only the top 1% of OC contractors in the country hold it. Qualification requires proven install quality, financial stability, strong customer reviews, and ongoing training verified by OC.
What is the Owens Corning Platinum Protection Limited Warranty?
It is Owens Corning's strongest warranty, available only through Platinum Preferred contractors. It covers materials and labor for up to 50 years. There is no proration during the first 10 years, meaning payouts are not written down over that period. The warranty is backed by Owens Corning — not by the contractor.
How is OC Platinum Preferred different from OC Preferred?
OC Preferred is the mid-tier contractor program. Platinum Preferred is the top tier with additional requirements for customer satisfaction, financial review, and install quality. Preferred unlocks the System Protection warranty; Platinum Preferred unlocks the Platinum Protection warranty with longer labor coverage and no first-10-year proration.
What Owens Corning shingles does DeHart Roofing install?
DeHart installs the full Owens Corning Duration line — TruDefinition Duration (the flagship), Duration Cool (Title 24 cool-rated), Duration Storm (impact-rated), and Duration Premium / Premium Cool. We also install Oakridge for budget-tier replacements.
Does DeHart install under Owens Corning Platinum Preferred?
Yes. DeHart installs under Owens Corning Platinum Preferred through parent company Econo Roofing, which holds the registration under the same CSLB #749551.
How do I verify DeHart Roofing is OC Platinum Preferred?
Visit owenscorning.com/roofing/contractor and search for DeHart Roofing in Turlock, CA. Our Platinum Preferred status is verified directly through Owens Corning's online contractor locator.
What is SureNail Technology?
SureNail is Owens Corning's patented reinforced nailing zone — a strip of fabric across the shingle's nailing area (where the nails go) that strengthens nail pull-through. It gives Duration shingles their 130 mph wind warranty. It also helps keep the shingle tabs sealed in hot Central Valley summers.
Does OC Platinum cost more than standard roofing?
Roofing materials cost the same regardless of contractor tier (rank). The Platinum Protection Limited Warranty has a small registration cost. In return, it gives you 25 years of labor coverage backed by Owens Corning — not just your roofer. For most homeowners replacing a roof they plan to keep for 20+ years, that coverage is worth it.
