Key numbers
45 verified hail storms with stones of 1.75 inches or larger reached Denver County from 1984 to 2026 in the storm records we keep; the largest measured 4.5 inches (softball size) on July 13, 2011 (NOAA NCEI).

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.
Metal roofing in Denver is worth it when you plan to stay in the home for a long time, want a roof that sheds snow, and are willing to pay more up front than you would for shingles. The right product depends on your roof’s pitch: Denver does not allow metal roof shingles on slopes below 3:12, so low-pitch roofs usually need a panel system such as standing seam. Denver also requires a mid-roof inspection on every metal roof, so the underlayment and flashing get checked before they are covered.
Which metal roof fits a Denver home
| Option | Best for | What to know |
|---|---|---|
| Standing seam panels | Modern homes, low or steep pitches, long runs | Concealed fasteners and raised seams. Panels expand and contract with Denver’s big temperature swings, and the clips are designed to allow that. |
| Metal shingles | Homes where you want a shingle or shake look | Interlocking pieces under 3 square feet each. Denver allows them only at 3:12 or steeper. |
| Stone-coated steel | Homeowners who want the look of shake or tile with steel underneath | A textured granule finish tends to hide minor hail marks better than smooth paint. |
| Exposed-fastener panels | Garages, sheds and outbuildings | Lower cost, but the screws and washers need checking over the years. |
Denver’s code draws the line between “metal roof panel” and “metal roof shingle” at 3 square feet of exposed surface per piece, which is why the slope rule applies to one and not the other.
What Denver’s code asks of a metal roof
- A permit and two inspections. Every replacement needs a permit. Metal roofs get a mid-roof inspection and a final.
- Valleys built for metal. On metal shingle roofs, valley flashing must be the same material as the roof, extend at least 8 inches from the centerline, and have a raised splash diverter rib. A 36-inch strip of Type I underlayment goes under valleys on slopes over 3:12.
- Snow load. Denver designs roofs for a 35 psf ground snow load, and metal sheds that snow faster than shingles do.
- Equipment and penetrations. New skylights, solar and vent penetrations need their own permit, so tell us early if you plan to add solar.
Cost, insurance and financing
Metal costs more than asphalt up front and usually lasts longer. See what a new metal roof costs in Denver for the numbers. If hail damaged your current roof, a policy usually pays to replace like with like, so metal is often an upgrade you pay the difference on, and financing can help with that part. The claim stays yours, and our photos make sure nothing gets missed in the scope.
Not sure metal is the right call? Compare it with tile and impact-resistant asphalt, or read our Denver residential roofing guide. Homeowners in the foothills often ask about metal for wildfire reasons too; our Golden and Louisville pages cover the local fire-rating rules.
