Littleton, Colorado's Most Trusted Roofing Contractor

Quadruple Manufacturer Certified

Most roofing contractors in Colorado carry one or two manufacturer certifications at most. Gates Enterprises holds four: GAF Master Elite, Owens Corning Preferred, Malarkey Emerald Premium, and CertainTeed ShingleMaster. Each certification requires verified installation training, minimum volume standards, and ongoing quality audits. The result for you is access to the top manufacturer warranty tiers — coverage that a non-certified installer simply cannot offer.

308 Google Reviews. 4.9 Stars.

We've earned 308 verified Google reviews from homeowners across the South Metro — Littleton, Englewood, Centennial, and beyond. A 4.9-star average isn't a marketing number, it's a reflection of how we operate on every job: clear communication, clean sites, no surprises on the invoice.

7,200+ Completed Projects Across Colorado

Since 2014, Gates Enterprises has completed more than 7,200 roofing and exterior projects statewide. That volume means our crews have seen every roof type, every permit process, and every insurance scenario the Front Range throws at them. Experience compounds — a crew that's done 7,000 roofs makes fewer mistakes than one that's done 700.

Insurance Claims Assistance

Hail damage claims are one of the more complicated things a homeowner deals with. We've assisted hundreds of Littleton homeowners through the documentation, inspection, and adjuster coordination process. We know what adjusters look for, how to document damage properly, and how to make sure your claim reflects the real scope of repair. You handle your deductible — we handle the rest of the process with you.

Arapahoe and Douglas County Building Code Experts

Littleton is one of the few cities in Colorado that straddles two counties — Arapahoe to the north and east, Douglas to the south. That split creates real complexity: permit jurisdictions differ, inspection requirements differ, and some HOA-governed areas add a third layer of approval. We've pulled permits in both counties, worked with both building departments, and navigated HOA architectural review on hundreds of Littleton jobs. This is not something you want to learn on your roof.

Local and Accessible

Our office is in Lakewood, less than 10 miles from most Littleton neighborhoods. We're not a national chain subcontracting to whoever's available — we're a Front Range company with crews that live and work in this market. When you call, you talk to someone who knows your city.

Ken Caryl Ranch and Columbine (1970s–1980s Construction)

Ken Caryl Ranch and the Columbine area represent Littleton's primary post-WWII expansion — large single-family homes built mostly between 1972 and 1988. These homes typically have 3-tab asphalt shingles originally installed 35 to 50 years ago, many of which have been replaced once or twice but are now at or approaching end of life again. Pitch profiles in this area are varied — Ken Caryl's hillside lots frequently have complex multi-plane roofs with multiple valleys and transitions, which require experienced installation crews. If you're in Ken Caryl or Columbine and haven't had a full inspection in the last two years, the combination of age and recent storm activity makes it a priority.

Historic Downtown Littleton and Bemis Park (Pre-1960s)

The oldest residential areas in Littleton — the neighborhoods around Main Street, Bemis Park, and the Santa Fe corridor — feature a mix of original slate, clay tile, and older composition shingles. These homes require a different approach than production-era subdivisions. We've worked extensively in this part of Littleton on partial re-roofs, valley replacements, and full system overhauls where original materials needed to be matched or upgraded carefully to maintain architectural character. If you own a historic Littleton property, material compatibility matters as much as price.

South Suburban / Highlands Ranch Border (1990s–2000s Builds)

The southern edge of Littleton, where Arapahoe County transitions toward Douglas County and the Highlands Ranch master-planned community, is primarily 1990s and early-2000s construction. These homes were built during a period when dimensional (architectural) shingles became standard, and many are reaching the 25–30 year mark on their original roof systems. This era also featured a lot of CertainTeed and Tamko product that has since been superseded by higher-performance lines. We frequently upgrade these roofs to current Owens Corning Duration or GAF Timberline HDZ systems with full ice-and-water shield at the eaves.

Sterne Park and Cherry Knolls (Mature Established Neighborhoods)

The Sterne Park and Cherry Knolls areas — mid-Littleton, bounded roughly by Bowles and Belleview — are a mix of 1970s and 1980s ranch-style and tri-level homes with mature tree canopy. Mature trees accelerate shingle wear through shade (moisture retention) and debris accumulation in valleys. These neighborhoods also have a higher proportion of older wood shake roofs that have been converted to composition at various points — the quality of those conversions varies significantly. We inspect the full deck condition during these jobs, not just the surface material.

City of Littleton Permits — Arapahoe and Douglas County Complexity

Roofing permits in Littleton are administered through the City of Littleton Building Division for properties within city limits — but Littleton's city limits are not co-extensive with its county lines. Depending on your address, your property may fall under Arapahoe County jurisdiction, Douglas County jurisdiction, or City of Littleton municipal jurisdiction, each of which has different permit application processes, fee schedules, and inspection timelines.

Gates Enterprises pulls the appropriate permit for every job — we've worked in all three jurisdictions and know which office to call and what documentation each requires. We do not start work without a permit in hand, and we schedule the required inspections as part of standard project management. For homeowners using insurance proceeds to fund a replacement, the permit is also often a condition of the claim being processed.

Additional complexity: Colorado's statewide adoption of the 2021 International Residential Code (IRC) includes updated requirements for ice barrier underlayment, ventilation, and valley flashing that some older installations don't meet. A permit-pulled replacement ensures your new roof is code-compliant — something that matters when you sell.

HOA Architectural Review in Littleton

Several Littleton communities have active HOA architectural control committees that must approve roofing material and color changes before work begins. Communities where HOA approval is commonly required include Ken Caryl Ranch, Columbine Valley, and the newer planned communities near the Highlands Ranch border. The approval process typically requires submitting a color sample, manufacturer spec sheet, and sometimes a photo of a comparable completed installation.

We handle HOA submittal paperwork as part of our process — we've worked with the Ken Caryl Ranch Master Association and other Littleton HOAs enough times to know what they require and how to get it through without delaying your project. HOA approval typically runs 7–14 days, so we factor this into the project schedule upfront.
