See what commitment to quality, integrity, and customer care
can do for your roof.
Your roof in Fort Collins works harder than most. Spring hail, sudden chinooks, and heavy, wet snow rolling off the foothills put constant stress on homes from Old Town to Rigden Farm and Bucking Horse. AC INC. Roofing brings Front Range expertise and meticulous installation to every project, from historic bungalows near College Avenue to newer builds south of Harmony Road. We handle required permits and inspections with the City of Fort Collins or Larimer County, follow current IRC-based codes, and install ice and water barrier at eaves where required, proper ventilation, and drip edge details to reduce ice dams and wind uplift.
Protecting What’s Under Your Roof Is What Matters Most to Us
Your roof does more than protect your home or business from the elements, it safeguards everything beneath it. From your family and belongings to your livelihood and operations, you deserve a roofing system that stands strong through every season.
Residential Roofing
Whether you need a shingle repair after a summer hailstorm or a full replacement, our HAAG Master–trained inspectors provide precise assessments and clear photos. We install premium asphalt, Class 4 impact-resistant systems, metal, and tile, tailored to snow load and freeze–thaw near the Poudre and west side neighborhoods by Horsetooth Reservoir.
Commercial Roofing
From Midtown retail to light industrial east of I-25, we repair and replace flat and low-slope roofs including TPO, EPDM, modified bitumen, and fluid-applied coatings. Proper drainage, edge securement, and wind-rated details are prioritized for Larimer County conditions.
Hail and Storm Response
Hail can bruise shingles, dent metals, and compromise membranes. Our team documents conditions, explains options, and provides scopes aligned with code requirements and manufacturer specifications. We assist owners through the process to the full legal extent permitted for roofing contractors.
Upgrades for Durability
Ask about Atlas Pro+ Platinum and GAF Certified system options with enhanced warranties, IBHS FORTIFIED upgrades for stronger edges and sealed roof decks, and snow retention strategies on metal to manage roof avalanching along the foothills.
Gutters, Siding, and Maintenance
We integrate new gutters and siding with roof projects and offer maintenance plans to keep penetrations sealed and ventilation balanced, extending service life in Fort Collins’ high-altitude climate.
Why Choose AC INC. Roofing
We are a licensed and insured Colorado contractor backed by national and state associations including RSRA, CRA, NRCA, and the American Policyholders Association. Our company achieved HAAG’s Master level training for precise storm evaluation, is Atlas Pro+ Platinum and GAF Certified for eligible system warranties, Directorii-certified with an added consumer guarantee, and offers IBHS FORTIFIED upgrades for resilience. You receive a local team that pulls the right permits, follows Fort Collins code details, and provides transparent proposals, photos, and communication from inspection to final clean-up. We support property owners with thorough documentation and coordination during insurance claims within the legal scope for roofers. Free roof inspections are available.
Do I need a roofing permit in Fort Collins?
Most reroofs within city limits require a building permit and final inspection. Our team handles permit applications and scheduling with the City of Fort Collins or Larimer County when the property is outside city limits.
What roofing materials perform best against hail here?
Class 4 impact-resistant shingles, thicker-gauge metal with proper underlayment, and well-secured flat membranes perform best. We offer Atlas and GAF shingle systems and metal options selected for local hail and wind.
How do you address snow and ice dams near the foothills?
We design for balanced attic ventilation, add ice and water barrier at eaves where required by code, and recommend snow retention on metal roofs where roof avalanching is a concern. Proper insulation and air sealing also help reduce ice damming.
Can you work with my HOA in neighborhoods south of Harmony Road or in Old Town?
Yes. We provide submittal-ready specs, color samples, and manufacturer data to help owners obtain HOA approvals while meeting Fort Collins code and wildfire-resistant, Class A fire-rated roofing standards.
What happens after a hailstorm?
Schedule a timely inspection so we can document conditions before additional weathering. Our HAAG Master–trained team provides photos, measurements, and a clear scope. We coordinate with your insurer within the legal limits of a roofing contractor without acting as a public adjuster.
Serving Old Town, Midtown, Harmony Corridor, and west-side neighborhoods near Horsetooth Reservoir with code-compliant roofing that stands up to hail, snow, and wind.
