Integrating Skylights Safely on Colorado Commercial Roofs
Colorado’s Front Range delivers big daylight—and big weather. If you’re considering skylights on a commercial facility in the Denver metro area or up to Cheyenne, WY, the design, product selection, and installation details must stand up to hail, snow loads, wind, and daily temperature swings. This guide outlines safe skylight integration practices for building owners and property managers, and how AC INC. Roofing (Advanced Consulting, Inc.) helps you execute them with confidence.

Why skylights on commercial roofs?
- Reduce electric lighting loads with natural daylight
- Improve occupant comfort in warehouses, retail, schools, and offices
- Potential productivity and safety gains from better visibility
Front Range design priorities
- Hail resistance: Select skylights with impact-rated glazing (e.g., polycarbonate domes or laminated glass) and ratings appropriate for Colorado’s frequent hail. Consider FM approvals or equivalent severe-hail testing where applicable.
- Snow and wind: Size curbs and attachment to handle local snow loads and high winds. Plan for drifting near parapets and rooftop equipment.
- Thermal performance and condensation control: Choose insulated curbs, thermally broken frames, and low U-factor glazing appropriate for our climate. Manage interior humidity and include vapor control to prevent condensation.
- UV and temperature swings: Favor materials with UV stability and sealants compatible with your roof membrane.
Product and curb selection
- Curb-mounted units are preferred for low-slope commercial roofs. Use factory-insulated curbs with welded corners. Typical best practice is a minimum 8″ flashing height above the finished roof surface; in drift-prone zones, taller curbs (often 12″) are prudent—coordinate with your structural engineer.
- Glazing options:
- Polycarbonate domes: excellent impact resistance for hail zones
- Laminated glass: clear visibility and good post-breakage integrity
- Multi-wall systems: improved insulation values
- Accessory options:
- Integrated shades or diffusers to control glare
- Operable units for ventilation (coordinate with controls and weather sensors)
- Skylight screens or guards for fall protection
Roof-system-specific detailing
TPO and EPDM roofs
- Use manufacturer-approved curb kits and membrane-backed flange details.
- Heat-weld (TPO) or adhere (EPDM) flashing to the curb with preformed corners; terminate above with appropriate counterflashing.
- Maintain minimum flashing heights and add walkway pads to create a protected service path.
Modified Bitumen roofs
- Use a multi-ply base/ply flashing with cap sheet and compatible metal counterflashing.
- Where heat is used, protect skylight lenses and frames; cold-applied or self-adhered flashing near the curb reduces heat risks.
- Add crickets/saddles upslope of the curb to divert water.
Metal roofs
- Install structural curbs designed for the specific metal panel profile (e.g., standing seam adapters) to maintain watertight seams.
- Use butyl tape/sealant compatible with the metal system and add snow retention upstream to prevent sliding snow/ice impacts.
Fluid-applied coatings
- Reinforce transitions at skylight curbs with embedded fabric per coating manufacturer details and preserve termination bars and counterflashings.
Water management essentials
- Positive slope: Tapered insulation and crickets upslope of skylight curbs stop ponding and ice buildup.
- Redundancy: Primary membrane flashing plus metal counterflashing/reglet where feasible.
- Compatible sealants: Match to membrane and skylight materials; avoid chemical incompatibilities.
- Drainage: Keep weep holes and gutters clear; add protection screens if debris is common.
Fall protection and roof access safety
- During construction and maintenance, treat skylights as fall hazards. Install OSHA-compliant skylight screens, guardrails, or ensure active fall arrest is used. Permanent guards/screens rated for expected loads provide ongoing protection for service crews.
- Add high-visibility walkway pads and warning lines around skylight zones.
Energy and code considerations (general guidance)
- Daylighting strategy: Coordinate skylight size, spacing, and diffusers with interior layout and controls to minimize glare and maximize energy savings.
- Thermal/air control: Insulated curbs, air sealing, and vapor management reduce condensation and heat loss.
- Fire/smoke: In certain occupancies, consider dedicated smoke vents (different from daylighting skylights) and coordinate penetrations with life-safety plans.
- Always verify local code requirements with your design team and authority having jurisdiction.
Snow, ice, and hail mitigation
- Curb height and crickets reduce drifting and ice dams.
- Snow retention above skylights on metal roofs protects lenses and frames.
- For hail-prone properties, specify impact-rated glazing and consider protective screens where appropriate.
Maintenance and inspection plan
- Semiannual inspections plus after major hail or wind events.
- Check lenses for crazing, fractures, seal failure, or UV degradation.
- Inspect curb seams, flashing terminations, and sealants; renew as needed.
- Keep drains, gutters, and weep openings clear; clean glazing with manufacturer-approved methods.
- Document conditions with photos. AC INC.’s HAAG-certified inspectors provide free roof inspections and thorough documentation—especially valuable for insurance claims after storms.
