Warranty Information
Roofing Warranties & Guarantees
Protecting your investment is central to everything we do.
Core Roofing Systems stands behind every installation and repair with industry-leading warranties backed by decades of proven protection. When you choose us as your Denver roofing contractor, you’re not just getting a roof — you’re getting peace of mind that comes with our 5-year workmanship guarantee and manufacturer warranties from partners like Owens Corning and Versico. Whether you’ve had your roof replaced, repaired, or inspected, our warranty coverage ensures you’re protected every step of the way.
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.

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.
