Do I need a permit for roof replacement or repair in Centennial?
Yes. In Colorado, roof replacement or repair generally requires a permit, and Centennial is no exception.
Because Colorado has no statewide building code, whether a reroof needs a permit and which IRC edition applies is set by your city or county, but most jurisdictions require a building permit to re-cover or tear off a roof. In mountain and foothill areas, roofs must meet local snow-load design and, in wildland-urban-interface zones, ignition-resistant (often Class A) roof-covering rules; confirm both with your building department before choosing materials. Centennial requires a permit when total roof repairs exceed 100 square feet, and repairs over 25 percent of the total roof area require a complete tear-off and reroof. All existing layers must be removed to the deck, and skip decking is allowed only where the gaps between boards do not exceed 1/2 inch. An ice barrier underlayment is required on all roofs and drip edge on all roof edges, and Centennial's design criteria are a 30 psf non-reducible roof snow load and a 115 mph wind speed (Sec. 18-2-30). If you miss the mid-roof inspection, the options are photos with the photo submission waiver, tearing off 10 percent of the shingles for an in-person mid-roof inspection, or a stamped engineer letter. Used or harvested roofing materials are not allowed, the approved permit must stay posted until final approval, and you must provide an OSHA-compatible ladder because inspectors do not supply or set one up.
