Not a Storm-Chaser. A Neighbor.

Denver's Locally-Owned Roofing Company Since 2001

We roof homes across every corner of the city: the historic bungalows of the Highlands and Berkeley, the tree-lined blocks of Washington Park and Cherry Creek, the brick two-stories of Park Hill and Capitol Hill, the newer builds of Central Park, and the classic homes around Sloan's Lake. Working the same streets for more than two decades means we already know how these roofs are built and how they fail.

Headquartered in Denver

Our office is at 4049 St. Paul Street in the Globeville and Elyria-Swansea area, ZIP 80216, just off I-70 and I-25. Our crews work the same neighborhoods they live in.

Dual top-tier certifications

We hold both Owens Corning Platinum Preferred and GAF Master Elite status, the top installer tier each manufacturer offers. Holding both at once is rare; our crews are trained and audited to the highest standards each brand sets.

Insurance claims from the inside

We are a Colorado Division of Insurance-approved continuing education provider, which means we teach insurance agents how roof claims work. We meet your adjuster on the roof so nothing is overlooked.

5-year workmanship warranty

Every roof we install carries a 5-year workmanship warranty on top of the manufacturer's material coverage, backed by BBB A+ accreditation and NWIR membership. Hours are Monday through Friday, 9 a.m. to 6 p.m., with same-day response for active leaks during business hours.

What We Do in Denver

Roof Repair, Replacement, Storm & Inspection Services

From a single failed vent boot to a full replacement after a hailstorm, one local team handles it, with a free inspection and a written, itemized estimate before any work begins.

Roof Repair & Leak Repair

A small leak in a Denver home rarely stays small. We trace leaks to their true source, often failed flashing, a cracked vent boot, or storm-damaged shingles, and most repairs finish in a few hours to a day. Honest repair-versus-replace advice, always.

Repair Services

Roof Replacement & Installation

Most residential asphalt replacements finish in one to two days, weather permitting. We tear off to the deck, repair damage, install proper underlayment, and match the material to your home, budget, and Denver's UV, hail, and snow.

Replacement Services

Storm, Hail & Insurance

Denver sits squarely in Colorado's Hail Alley, and much of the damage is not visible from the ground. We document everything, meet your adjuster on the roof, and file supplements when the approved scope misses line items.

Storm Services

Roof Inspections

The cheapest insurance a Denver homeowner can buy. Whether you are buying or selling, coming off a hailstorm, or your roof is getting up in years, we evaluate every slope and give you a straight recommendation: monitor, repair, or replace.

Schedule an Inspection

Considering a longer-lasting system? Our Denver metal roofing options deliver 40 to 70 years of service with Class 4 hail resistance. And if a storm already did the damage, our insurance claims assistance team handles the whole process, from documentation through the completed repair.

Frequently Asked Questions

Look for a licensed, insured, locally established contractor with verifiable credentials and reviews. Core Roofing Systems has roofed Denver from our 4049 St. Paul Street office since 2001, holds Owens Corning Platinum Preferred and GAF Master Elite status, and offers free inspections. Call 303-295-2220.

Choose licensed, insured contractors with manufacturer credentials (Owens Corning Platinum Preferred, GAF Master Elite), a local address, a written workmanship warranty, and honest insurance-claim handling. Avoid storm-chasers and deductible-waiving offers. Core checks every box: 25-plus years in Denver, a named local team, and a 5-year workmanship warranty.

Core provides residential, multifamily, and commercial roofing (repair, replacement, and inspection) plus specialty metal (standing seam, stone-coated steel, copper), slate, gutters, skylights, storm and hail restoration, and insurance-claim assistance. We serve the full Denver Metro from our St. Paul Street headquarters.

Replacement cost depends on your roof's size, pitch, complexity, and the material you choose; metal and specialty materials cost more than asphalt. Hail-claim replacements may be largely insurance-covered minus your deductible. Core provides free inspections and written, itemized estimates so there are no surprises.

Denver's intense UV, hail, and freeze-thaw favor impact-rated and durable materials. Class 4 impact-rated asphalt or metal resist hail and may earn insurance discounts. We assess your home, budget, and goals and recommend the right system, from architectural shingles to standing seam metal.

Yes, it is a core strength. We meet your adjuster on the roof, document hail and wind damage, file supplements when warranted, and manage the approved repair or replacement. Core is even a Colorado Division of Insurance-approved CE provider that teaches agents the claim process.
