Skylight Installation in Chicago, IL

What Does Skylight Installation Involve?

Skylight installation is the process of cutting a precise opening in your roof, framing it to support the skylight unit, and sealing it against moisture and air leaks. At Chicago Roofing Team, we handle everything from structural reinforcement to interior trim. We use only code-compliant flashing systems and high-performance glazing to ensure your skylight performs for decades.

Materials and Methods for Chicago Homes

We install three primary types of skylights: fixed skylights (non-venting, for maximum light), ventilating skylights (operable, for fresh air), and tubular skylights (compact, for small spaces). For Chicago’s freeze-thaw cycles, we recommend double- or triple-pane low-E glass with argon gas fill. Our flashing methods include step flashing under siding, continuous flashing over the curb, and ice-and-water shield in all valleys. We use Velux and Fakro units for their proven durability.

How Much Does Skylight Installation Cost in Chicago?

Typical costs for skylight installation in Chicago range from $1,200 to $3,500 per skylight, including labor and materials. Fixed skylights start around $1,200, while ventilating models run $2,000–$3,500. Tubular skylights cost $600–$1,200. Factors affecting price include roof pitch, roofing material (asphalt shingle vs. tile), and whether you need drywall repair or electrical work for a solar-powered model.

Signs You Need a New Skylight

• Water stains or dripping around the skylight frame
• Fogging or condensation between glass panes
• Cracked or broken glass
• Drafts or temperature swings near the skylight
• Visible gaps or deteriorated caulking
• Difficulty opening or closing a ventilating skylight
• Increased energy bills due to heat loss
• Ice dams forming around the skylight in winter

Step-by-Step Skylight Installation Process

1. Inspection and Planning: We assess your attic structure, roof slope, and interior layout. We check for obstructions like rafters and confirm the best location for maximum daylight.
2. Roof Opening and Framing: We mark and cut the roof deck, then install a reinforced curb or frame to support the skylight. This step takes 1–2 hours per skylight.
3. Flashing and Waterproofing: We apply ice-and-water shield around the opening, then install step flashing, counterflashing, and a continuous flashing pan. All joints are sealed with urethane caulk.
4. Skylight Installation and Sealing: We set the skylight unit into the curb, secure it with corrosion-resistant screws, and seal the perimeter. For ventilating models, we connect the opening mechanism.
5. Interior Trim and Finish: We install drywall backer, insulation, and a light shaft. Our carpenters trim the opening with wood or PVC to match your ceiling.
6. Cleanup and Inspection: We remove all debris, test the skylight operation, and walk through the attic to confirm no leaks. Total timeline: 4–8 hours for a single skylight.

Insurance, Warranty, and Local Climate Considerations

Skylight installation may be covered by homeowners insurance if caused by storm damage — we can help document the claim. We offer a 5-year workmanship warranty and pass through manufacturer warranties (10–20 years on glass, 5–10 years on seals). For Chicago’s climate, we recommend low-E glass to reduce heat loss in winter and solar heat gain in summer. We also install snow guards above skylights to prevent ice dam damage.
