Colorado’s Front Range winters bring temperature swings, snow loads, chinook winds, and the occasional hailstorm—conditions that can shorten a roof’s service life if you’re not prepared. Whether you manage a commercial facility or own a home in the Denver metro area, the right maintenance steps before, during, and after winter can prevent leaks, protect warranties, and extend the life of your roof.
AC INC. Roofing (Advanced Consulting, Inc.) is a licensed, insured, and 5.0-star rated roofing contractor serving the Denver metro area, the Front Range, and Cheyenne, Wyoming. Our HAAG-certified inspectors provide free roof inspections, and our team specializes in residential and commercial roof repairs, replacements, storm restoration, roof rejuvenation, siding and gutter installation, and more.
Why Colorado winters are hard on roofs
- Freeze–thaw cycles: Daytime melting and overnight refreezing can force water under shingles and into seams, leading to leaks and ice dams.
- Snow loads and drifts: Heavy, wet snow and wind-driven drifts add concentrated weight to eaves, valleys, and parapet corners.
- High winds: Chinook winds can lift shingles and stress flashing on both steep- and low-slope roofs.
- Elevated UV at altitude: Winter sun still ages membranes and shingles, especially after granule loss from hail.
Pre-winter checklist (October–November)
- Schedule a professional inspection: Our HAAG-certified inspectors document conditions with photos and a written report—ideal for establishing a baseline before winter and for insurance purposes. Inspections are free.
- Clean debris: Clear leaves, needles, and branches from roofs, valleys, gutters, downspouts, scuppers, and drains to prevent backups and ice dams.
- Check flashing and penetrations: Inspect areas around chimneys, skylight curbs, wall intersections, HVAC curbs, and pipe boots. Repair loose metal, deteriorated sealants, and nail pops.
- Evaluate attic/roof ventilation: Balanced intake and exhaust reduces condensation and ice-dam risk. We can assess roof-side ventilation components and detailing.
- Trim overhanging branches: Reduce abrasion on shingles and puncture risks on membranes.
- Document everything: Keep dated photos and notes; they’re invaluable if a storm claim becomes necessary.
Residential roofing: winter maintenance tips
- Shingle and flashing repairs: Replace lifted, cracked, or missing shingles; address nail pops and exposed fasteners; secure chimney and wall flashing; and verify drip edge and gutter apron coverage.
- Gutter and downspout performance: Ensure gutters are clean and properly pitched. Extend downspouts to direct meltwater at least 4–6 feet away from the foundation. AC INC. Roofing installs and replaces gutters.
- Ice dam prevention: Keep eaves and valleys clear of debris and verify ventilation is functioning. Reduce warm-air leakage from the living space where possible. Our team can inspect roof vents, baffles, and roof details that influence ice-dam formation.
- Attic condensation watch-outs: In extreme cold, look for frost on roof sheathing. Make sure bath, kitchen, and dryer vents terminate outdoors and that roof penetrations are sealed against backflow.
- Snow management safety: Avoid climbing onto icy roofs or chipping at ice dams, which can damage shingles. If removal is necessary, use a roof rake from the ground or hire a qualified professional. Focus on relieving heavy, uneven drifts and keeping eaves clear for drainage.
- Consider roof rejuvenation: If your asphalt shingles are aging but still structurally sound, AC INC. Roofing offers roof rejuvenation to help restore flexibility and extend service life through freeze–thaw cycles.
Commercial and multifamily: low-slope/flat roof priorities
- Membrane integrity (TPO, EPDM, Modified Bitumen): Inspect seams, laps, terminations, and edge metal. Repair loose seams, punctures, and deteriorated sealant at penetrations and pitch pans.
- Drains, scuppers, and gutters: Confirm strainers are installed and clear. Test drain flow before freeze events. Keep scuppers and conductor heads free of ice and debris.
- Equipment curbs and penetrations: Check rooftop unit (RTU) curbs, pipe boots, and pitch pockets for splits or dry sealants. Verify counterflashing and copings are secure.
- Walkways and traffic: Add or verify walkway pads to protect membranes along service routes. Limit unnecessary foot traffic in freezing conditions.
- Ponding water after melt: Address ponding areas promptly. In the right conditions, fluid-applied coatings can be planned for warmer months to extend membrane life and improve reflectivity.
- Snow load and drifting: Watch for drifts against parapets and around RTUs. When snow depth or drift concentration looks excessive, contact a qualified professional—don’t allow shovels or sharp tools on membranes.
After a storm: hail or high-wind response
- Visible signs of damage: Look for bruised shingles, circular impact marks, granule loss in gutters, dented vents, creased tabs, displaced tiles, or membrane punctures and loose seams.
- Immediate actions: Protect interior areas, document with photos, and avoid climbing onto the roof.
- Professional help: AC INC. Roofing’s Master HAAG–certified team specializes in storm-damage evaluation, thorough documentation, and insurance claims support. We are members of RSRA, CRA, NRCA, and the American Policyholders Association and uphold best practices for consumer protection.
Repair, rejuvenate, or replace?
- Repair: Ideal for localized issues—flashing failures, a few missing shingles, or isolated membrane punctures.
- Rejuvenation: Great for aging asphalt shingles that are drying and losing flexibility. A rejuvenated surface can better withstand winter expansion/contraction and extend service life.
- Replacement: Recommended when systemic damage or end-of-life conditions exist. We install premium systems including impact-resistant asphalt shingles, metal and tile roofing, and commercial TPO, EPDM, and Modified Bitumen. For additional resilience, our Fortified Roofing Solutions certification means we can build to standards designed to withstand up to 130 mph winds, EF-2 tornadoes, and 2″ hail.
