Key numbers
18.34 million occupied U.S. homes were built in the 1970s, the most of any single decade bin in RECS 2020 (20.26 million were built before 1950) (U.S. Energy Information Administration (EIA), 2020).

Replacing an asphalt shingle roof on a Denver home typically costs $16,000 to $40,000, and the average job we see is closer to $25,000. Asphalt shingles are the most common roof in Denver, and the price depends on the size and pitch of the roof, the shingle line, how many old layers come off, decking repairs, and code items such as the wind rating your address requires. These are planning numbers, not a quote. Premium materials cost more; see the links to our Denver metal, tile, slate and synthetic cedar guides below.
The Denver cost drivers
| Driver | What to know |
|---|---|
| Size and pitch | Material and labor are priced per square (100 square feet). Steep, two-story roofs take more time and safety setup. |
| Shingle line | Architectural shingles are the standard; premium and impact-resistant lines cost more. |
| Wind zone | Denver requires higher-rated shingles west of Federal Blvd. and again west of Sheridan. |
| Old layers | Where two or more layers exist, Denver requires removal to the deck, which adds tear-off and disposal. |
| Decking | Wide gaps or damaged boards must be fixed before shingles go on. |
| Insulation | An uninsulated roof whose sheathing is exposed during the job must be insulated to the energy code. |
What Denver code requires on a replacement
From the City and County of Denver Roofing Guide and Checklist:
- Permit. Any repair over 10 percent of the roof or two squares needs a permit, so a full replacement is always permitted.
- Wind rating. Shingles must be labeled to ASTM D7158 (or D3161 if not covered), rated 115, 125 or 140 mph depending on the zone.
- Ice barrier. Self-adhering ice and water membrane at the eaves is not required by Denver code. Some contractors include it anyway, so check whether your bids do before comparing prices.
- Inspections. One- and two-family asphalt roofs get a final inspection, with a mid-roof inspection only if needed. Failed items mean a $100 re-inspection fee.
- Licensing. Shingle work requires a Denver D-Roof Shingles license; membrane sections over 10 percent of the roof require a D-Roof Covering/Waterproofing license.
How to compare Denver bids
- Make sure each bid prices the same scope: tear-off, underlayment, flashing, drip edge, ventilation and decking allowance.
- Ask who pulls the permit, and for the license and recent local project photos. A contractor who will not pull a permit is a warning sign.
- Check the contract. Colorado requires a written contract with the scope, approximate dates and costs, the contractor’s contact details and liability insurer, a 72-hour cancellation right, and a statement that your payment is held in trust until materials arrive or most of the work is done.
- Watch for rush pricing. Urgent scheduling and after-storm demand can raise prices. Get a temporary repair if needed and take time to compare.
