A storm counts when the library lists Denver County among the areas it hit. Each hail size is the storm's largest report, which may have fallen in a neighboring county, and insured losses cover every area the storm hit.
Storm damage roof repair in Denver means stopping leaks fast, documenting hail and wind damage for your claim scope, and then repairing or replacing the roof to Denver code. Integrity Roofing and Painting does all three from our office at 13275 E Fremont Pl in Centennial, starting with a free inspection and photos of every hit.
Emergency tarping and leak repair
After a hailstorm or a heavy spring snow, water that gets past the shingles soaks insulation and decking and can lead to rot and mold. We tarp roofs and make temporary fixes to stop water from getting in, then locate every leak source so the permanent repair actually holds.
Hail damage
Denver hail can crack, bruise, and knock granules off shingles, dent vents and gutters, and break tiles. Damage is often invisible from the ground, so we inspect the roof itself and photograph every hit. Read about the May 8, 2017 Denver hailstorm and our guide to navigating roof damage after a Denver storm. For recent storm tracks and the Denver rules on partial repairs and reused tile, see hail damage roof repair in Denver.
Wind damage and Denver’s wind zones
Denver’s high-wind events peel back shingles and break their seals, which lets wind-driven rain in. Replacement shingles must meet the wind rating Denver requires where you live: shingles labeled to ASTM D7158 (or D3161) with a minimum of 115 mph east of Federal Blvd, 125 mph between Federal and Sheridan, and 140 mph between Sheridan and Kipling. See high winds and roof damage in Denver.
Snow and ice damage
Heavy snow strains older roof framing, and meltwater that refreezes at the eaves forms ice dams that push water under shingles. We repair the damage and the underlying cause.
Before you sign with any storm contractor
After a big storm, out-of-town crews knock on doors across the metro. Before you sign with anyone, including us:
- Ask who pulls the permit. A Denver repair larger than 10% of the roof or two squares (whichever is smaller) needs one, and so does every replacement. Low-slope membrane roofs must be installed by a contractor with a Denver D-Roof Covering/Waterproofing license.
- Get a written contract. Colorado law (C.R.S. 6-22-103) requires one before any residential roofing work, listing the scope, materials, approximate dates and costs, the contractor’s physical address and phone, and its insurer and surety. It must let you cancel within 72 hours of signing for a full refund of any deposit, and the contractor must hold your payment in trust until materials are delivered or most of the work is done.
- Know your out if the claim is denied. You can cancel within 72 hours after written notice that your claim was denied in whole or in part (C.R.S. 6-22-104).
- Walk away from deductible offers. A contractor paid from an insurance claim may not promise to pay, waive, or rebate your deductible (C.R.S. 6-22-105).
When the roof is replaced, we tear off to the deck, because Denver allows no more than two layers and we want to see the decking. For the claim itself, start with our Denver roof insurance claim help guide to the Colorado rules, or book a Denver roof inspection to see what the storm did, then read what to do if an adjuster denies your claim and how long you have to recover depreciation.
