Gutter Installation in Denver, CO

Gutters in Denver: what local homeowners should know

The Front Range is one of the most hail-prone areas in the US, and roof and gutter replacements after hailstorms are common across the Denver metro. New seamless gutters are often installed right after a hail-damaged roof is replaced.

Denver’s freeze-thaw cycles and spring snowstorms put stress on gutters, and melting snow on sunny winter days can refreeze in gutters overnight. Strong hangers, proper pitch and downspouts that drain away from walkways help prevent ice problems.

Dry climate, hard weather

Denver is semi-arid: normal annual precipitation is only about 14.5 inches (NWS Boulder, 1991–2020 normals). But the weather that does arrive is hard on gutters. The National Weather Service in Boulder notes that Denver’s seasonal snowfall averages in the mid-50-inch range at the historical observing sites, and spring storms in March and April often bring the heaviest, wettest snow of the year. That snow loads roofs and gutters, melts in strong sun and refreezes overnight.

The other big factor is hail. Colorado ranks second only to Texas in hail-loss insurance claims, according to National Insurance Crime Bureau data reported by the trade press, and the Front Range sees hail most summers. Hail that damages roofs also dents aluminum gutters and crushes downspout elbows, so many Denver gutter replacements happen together with insurance-covered roof replacements.

Freeze-thaw and frozen downspouts

Denver’s sunny winter days are the reason its gutters freeze so often. Snow on the roof melts in the afternoon sun, runs into gutters and downspouts in the shade, and freezes solid overnight. Day after day, ice builds up in the channel and plugs downspouts, especially on north-facing sides and at the bottom elbows.

What helps: gutters with a proper slope so water does not sit, larger 3x4-inch downspouts that are harder to plug, hidden hangers at close spacing to carry the weight of ice, and downspouts that discharge where meltwater will not refreeze on walks and driveways. On metal roofs, which shed snow suddenly, snow guards on the roof protect the gutters below. For ice dams, the long-term fix is in the attic: air sealing, insulation and ventilation. See ice dams and gutters.

Typical costs in Denver

These are published cost figures for orientation only, not quotes. City averages include smaller jobs such as partial runs; a full seamless system on a large or two-story home usually lands at the upper end of the range or above. The installer you are connected with measures your home and gives you the actual price.

Licensing in Denver and the suburbs

Colorado has no statewide general contractor license. Instead, cities license contractors. The City and County of Denver licenses contractors through Community Planning and Development (CPD), which also issues the supervisor certificates some licenses require. Aurora, Lakewood, Arvada, Westminster, Littleton and other suburbs have their own licensing and permit rules.

Ask the installer which license they hold for your city and verify it. After hailstorms, the Front Range sees many out-of-state crews; check reviews that go back several storm seasons, get a written, itemized estimate, and do not pay in full before the work is done.

Rain barrels are legal, with limits

Colorado water law long made collecting rainwater a gray area. Since August 2016, state law (HB16-1005) allows single-family homes and buildings with up to four units to collect rain from rooftop downspouts in up to two rain barrels with a combined capacity of 110 gallons, for outdoor use on the same property, such as watering lawns and gardens. If you want barrels, plan them when the gutters go in: the installer can place downspouts where a barrel fits, with an overflow that still drains away from the foundation. In winter, disconnect barrels so they do not freeze and crack.

Choosing gutters and guards for a Denver home

• Heavier material for hail: heavier-gauge aluminum or steel. See gutter materials compared and hail-damaged gutters.
• Larger downspouts that are harder to freeze shut: downspouts and drainage.
• Hidden hangers at close spacing for heavy spring snow: seamless gutter installation.
• Guards that shed snow under cottonwoods, elms and pines: gutter guards.

Independent installers take calls from across the Denver area, including Denver, Aurora, Englewood, Littleton, Lone Tree, Parker, Castle Rock, Arvada, Wheat Ridge, Westminster, Broomfield, Commerce City, Lafayette, Louisville, Elizabeth, Franktown, Larkspur, Monument and Palmer Lake.
