Core Roofing Systems stands behind every installation and repair with industry-leading warranties backed by decades of proven protection.

Why Warranty Coverage Matters

Complete Protection for Your Roofing Investment

5-Year Workmanship Warranty

Every installation and repair we perform is covered by our comprehensive 5-year workmanship warranty. We stand behind our labor quality, craftsmanship, and attention to detail. This means if a problem arises from our installation or repair work within five years, we fix it at no charge.

Owens Corning Manufacturer Coverage

As an Owens Corning Platinum Preferred Contractor, we install shingles and roofing products that carry extensive manufacturer warranties on residential and commercial projects. Owens Corning warranties often extend 20–50+ years depending on the product line, protecting against material defects and weathering.

Versico Authorized Warranty Protection

For commercial and multifamily membrane roofing (TPO, EPDM, PVC), our Versico authorization gives you access to manufacturer warranties that cover material failures and defects. A non-authorized installer can void these protections — we keep yours intact.

Documented Warranty Records

We maintain complete records of every warranty on every project. When you sell your home or building, warranty documents transfer with the property, adding value and protection for future owners. We can retrieve and explain your coverage anytime.

Transparent Coverage Details

Many contractors leave homeowners confused about what’s actually covered. We explain exactly what’s included, excluded, and what steps to take if you need to file a claim. No surprises — just clear answers.

Local Expertise Backing Your Coverage

With 25+ years serving Denver, Aurora, and the surrounding metro, we’ve learned which materials hold up best in Colorado’s climate. Our warranty commitment reflects that experience — we wouldn’t offer it if we weren’t confident in the work.

Frequently Asked Questions About Roofing Warranties

Our workmanship warranty covers five years from your project completion date. Manufacturer warranties often extend 20–50+ years depending on the product. We’ll clarify both timelines when you sign the contract.

Yes. Owens Corning and Versico warranties transfer to future owners if they’re registered. We help with the transfer process and provide the necessary documentation. Our workmanship warranty stays with the original homeowner, but the product warranties follow the property.

Unauthorized work can void manufacturer warranties. Before hiring another contractor, check your warranty terms. We recommend using authorized installers for any follow-up work. If you have questions about maintenance, call us first — we may be able to help.

No. Storm damage (hail, falling trees, wind, etc.) is typically covered under homeowners insurance, not the roof warranty. We help file insurance claims and document damage, so contact us immediately if your roof is storm-damaged.

Workmanship covers the quality of our installation and labor. Product warranty covers the material itself against manufacturing defects. Both protect you, but for different things. We maintain both on every job.

Our standard 5-year workmanship warranty is comprehensive and represents our commitment to quality. For products like Owens Corning shingles, extended product warranties may be available — ask us about options during your estimate.

After five years, workmanship warranty coverage ends, but manufacturer warranties continue (often 20–50 years or longer). You’re still protected against material defects. This is why quality installation matters — it extends the life of your roof beyond the workmanship period.

We maintain records of every warranty on file. Call us with your address and project year, and we can pull your coverage details instantly. You can also check your original warranty certificate for dates and coverage terms.

Don’t worry. We keep copies of all warranties in our files. Contact us with your address and project date, and we can reissue documentation or provide proof of coverage for insurance or resale purposes.

Our warranty does not require specific maintenance plans, but we do recommend regular inspections and gutter cleaning to prevent water damage. Severe neglect (like complete gutter blockage causing water backup) could affect a claim, but normal maintenance doesn’t void coverage.

Owens Corning maintains a searchable contractor directory at their website. You can verify our status there. We also display our certification credentials on our About page.

Warranty Protection

Your Roof is Protected — Here’s Why That Matters

A roof is one of your home’s most significant investments. When something goes wrong, costs spike fast. Our dual-layer warranty approach — combined workmanship plus manufacturer coverage — means you’re protected from installation failures and material defects across the Denver Metro region.

Core Roofing’s 5-Year Workmanship Warranty

Our workmanship warranty covers all labor, installation methods, and craftsmanship performed by our team.

What’s Covered

  • Improper installation or application of materials
  • Flashing and sealing issues caused by our work
  • Gaps, leaks, or water intrusion from installation errors
  • Adhesive or fastening failures due to incorrect application

What’s Not Covered

  • Normal wear and tear over time
  • Damage from extreme weather (hail, tornados, wind) — covered under insurance claims
  • Manufacturer material defects — covered under product warranties
  • Maintenance issues unrelated to installation (clogged gutters, etc.)
  • Damage from third parties or unauthorized work

How Your Warranty Starts

Your 5-year warranty begins on project completion. We issue a written certificate clearly stating the coverage period and terms — essential for future reference and property transfers.

Owens Corning & Manufacturer Warranties

Beyond our own guarantee, the materials we install carry substantial manufacturer protection. These warranties are transferable, meaning they pass to future owners if you sell.

Owens Corning Product Warranties

  • Asphalt & Architectural Shingles: Coverage spans 20–50 years depending on product line (Duration®, Duration FLEX®, TruDefinition®). Includes weathering, impact resistance, and material defects.
  • Warranty Validity: Your Owens Corning warranty is valid only with an Owens Corning Platinum Preferred Contractor (that’s us). Non-certified installations void manufacturer coverage.

Versico Roofing Warranties

For commercial projects using TPO, EPDM, or PVC membranes, Versico authorizes us to offer:

  • Material Warranties: 10–20 years on membrane integrity and material defects
  • Labor Workmanship: Complementary to our own 5-year guarantee
  • System Coverage: When Versico-authorized contractors install Versico products in a Versico-approved system, coverage extends to the full roof assembly

Other Manufacturers

We work with slate, copper, and specialty manufacturers whose warranties extend 30+ years. We review your specific product warranty during planning and provide all documentation.
