Why Denver Homeowners Choose Core Roofing for Gutters

Certified Owens Corning Partner

We’re an Owens Corning Platinum Preferred Contractor, giving you access to premium gutter systems and their full warranty coverage. Our crew understands gutters as an integrated part of your roof system, not a separate afterthought.

Handles Colorado’s Water Challenges

Denver gets 20+ inches of rain annually, plus heavy spring snowmelt. Our gutter sizing and pitch angles account for these seasonal surges. We’ve handled thousands of installations across the Denver Metro, so we know what works when the gutters are tested.

Seamless & Custom Design

We bring our gutter machine to your home and form gutters on-site. No seams means no leak points. Every gutter is built to your roof’s exact dimensions and slope, with color options matching your trim or siding.

Gutter Guard Systems Included

Heavy rain or leaf buildup? Our gutter guard solutions prevent clogs while remaining serviceable. Whether you choose a surface tension guard, mesh system, or sealed gutter, we’ll spec the best option for your home’s trees and water flow.

5-year workmanship warranty

Every installation includes our 5-year workmanship guarantee on labor. Owens Corning gutters also carry their manufacturer warranty, so you’re protected twice over.

Our Process

How We Install Your Gutter System

Core Roofing Systems gutter installation process in Denver
  1. 01

    Site Assessment & Measurement

    Our crew visits your home to evaluate roof edges, downspout locations, and existing damage. We photograph the roofline, measure gutters, and identify where water currently pools. If you’ve had previous problems with ice dams or water backing up, we’ll trace those issues to their source.

  2. 02

    Design & Material Selection

    We’ll recommend K-style or half-round gutters, choose a color, and specify gutter guard type. If you have a complex roofline (multiple peaks, valleys, or dormers), we’ll create a detailed plan showing every downspout, elbow, and bracket location.

  3. 03

    Gutter Fabrication On-Site

    We bring our seamless gutter machine to your property. Rather than piecing together sections at a shop, we form gutters on your roofline in one continuous piece per roof section. This eliminates seams and dramatically reduces leak risk.

  4. 04

    Bracket Installation & Hanging

    Your gutters are only as good as the brackets holding them. We install heavy-duty brackets every 24 inches (or closer in high-load areas), slope them toward downspouts at a 1/4-inch drop per 10 feet, and ensure every corner is secure and waterproof.

  5. 05

    Downspout & Discharge System

    We’ll install downspouts, elbows, and final discharge points. We extend downspouts at least 4–6 feet away from the foundation (or into a drainage swale if present) to prevent foundation settling and basement water intrusion.

  6. 06

    Gutter Guard Installation & Final Walkthrough

    If you’ve selected a guard system, we’ll install it and test water flow. We’ll show you how to care for your gutters, discuss seasonal maintenance, and explain how to spot future problems. Even with guards, twice-yearly gutter checks keep debris from building up around the guard edges.

Leaf Protection

Gutter Guards & Leaf Protection

Gutter guards keep leaves, pine needles, and roof grit out of your gutters so water drains freely, which protects your fascia, foundation, and landscaping and reduces risky ladder time cleaning gutters. We install micro-mesh, surface-tension, and screen systems and spec the option that fits your roof pitch, tree cover, and typical debris load. Guards do not make gutters completely maintenance-free, but they slow buildup and make seasonal checks faster and safer. If your existing gutters are sound, we can add guards to them; if they sag or leak, we will recommend replacement first so the guards have a solid channel to protect.

Formed On-Site

Seamless Gutter Replacement

When gutters pull away from the fascia, leak at the seams, or cannot keep up with Colorado’s spring runoff, replacement is usually a better long-term value than repeated patching. We form seamless gutters on-site in one continuous run per roof section, removing the seams where sectional gutters crack and leak; seamless runs last longer, look cleaner, and hold up better under snow and ice. During replacement we check downspouts, brackets, and slope, and extend discharge points away from the foundation. Because we roof and gutter in one visit, we can replace damaged gutters alongside roof repairs or a full roof replacement.

Built for Colorado

Why Colorado Homes Need the Right Gutters

Colorado gutters take a beating. Correctly sized gutters, proper slope, and adequate downspouts handle these loads and keep water moving away from your home.

Spring Snowmelt

Heavy snowmelt sends large volumes of water off the roof in a short window; undersized or poorly sloped gutters overflow and dump it against the foundation.

Winter Ice Dams

Clogged or under-drained gutters contribute to ice dams that back water up under the shingles.

Hail Evidence

After a hailstorm, dented gutters are often one of the clearest visible signs a roof took a hit, which can support a storm-damage insurance claim. See our guide to the warning signs of hail damage.

Frequently Asked Questions About Gutters & Gutter Guards

Both work, but gutter guards are an investment in your long-term convenience. Cleaning gutters twice yearly on a ladder is dangerous—falls are among the most common home injuries. Guards don’t eliminate all maintenance, but they reduce debris buildup by 80–90% in most homes. If you have large deciduous trees, a guard system makes a huge difference.

Quality guards are designed to handle Denver’s typical rainfall rates (1–2 inches per hour). Micro-mesh and solid guards work by directing water flow across their surface and into the gutter opening. In extreme events (flash floods), even a wide-open gutter can overflow. The key is proper downspout sizing, which we handle during design.

With guards, most homeowners inspect gutters twice yearly (spring and fall) but only clean them if debris accumulates around the guard edges. Without guards, clean gutters every 3 months during high-leaf seasons. In Denver, winter can bring ice dams if gutters are clogged, so fall cleaning is especially important.

Seamless gutters are formed on-site in one continuous piece per roof section. Sectional gutters are pre-made segments pieced together with joints and sealant. Seamless gutters have fewer leak points, better appearance, and last longer (25–40 years vs. 15–20 years for sectional). We install seamless as standard.

Yes. If your current gutters are in good condition but clogged with debris, we can clean them thoroughly and install guards. If gutters are sagging, corroded, or leaking, we’ll recommend replacement—adding a guard to a failing gutter doesn’t solve the underlying problem.

Gutter pricing depends on your roof’s linear feet, guard type, and any custom work (bends, skylights, multiple levels). Contact us for a free estimate. We’ll measure your home and provide an exact quote.

Ice dams form when heat escapes the attic, melting snow on the roof. That water refreezes in unheated gutters. Gutters alone don’t prevent ice dams—proper attic insulation and ventilation do. However, well-designed gutters with proper slope will drain meltwater faster, reducing backup risk.

Yes. Commercial gutters often see higher water volumes and rooftop activity. We handle commercial gutter installation with extra-heavy-duty systems designed for flat roofs and high-wind areas. Call us for a commercial consultation.

Storm damage is common in Colorado. Our storm evaluation team can assess hail damage, ice dam debris, or wind damage to gutters. Many homeowners’ insurance policies cover gutter replacement from storms. Learn how we handle insurance claims.

Most residential homes take 1–3 days depending on roof complexity and system type. Simple one-story homes with standard gutters may finish in one day. Two-story homes with multiple roof lines, valleys, and skylights often take longer. We’ll give you a timeline during the quote phase.

Gutter installation cost in Denver depends on the linear footage of your roofline, the gutter and downspout size, whether you add gutter guards, and any complex work like multiple stories, valleys, or skylights. Any figures you see published are Colorado market ranges and vary by home, so the only accurate way to know your price is a measured quote. Contact us for a free estimate and we will measure your home and give you an exact number, with financing available if you want to pair gutters with roof work.

For many Colorado homes, yes. If you have mature trees, pines, or a roof that sheds grit, guards reduce how often gutters clog and overflow, which protects your fascia and foundation and cuts down on risky ladder work. Guards are less essential on homes with little tree cover. We will look at your tree cover, roof pitch, and typical debris and tell you honestly whether guards are a good investment for your property.

Most homes use 5-inch K-style gutters, but larger roofs, steep pitches, or areas that collect heavy spring snowmelt often do better with 6-inch gutters and larger downspouts that move more water in a short time. The right size depends on your roof area, pitch, and how much water drains to each downspout. We calculate this during the site assessment so your gutters can keep up with Colorado’s runoff and summer thunderstorms.

Yes. Hail commonly dents gutters and downspouts, and that damage is often visible evidence that the roof was hit too. We inspect and replace hail-damaged gutters, and because we handle storm and insurance work, we can document the damage and coordinate with your adjuster. If your gutters are dented, it is worth having the roof evaluated at the same time.
