Skylight Installation Chicago | VELUX Certified

☆ Operation Overview

Skylight Installation in Chicago

A well-installed skylight transforms interior spaces — flooding rooms with natural light, reducing daytime energy costs, and creating a dramatic architectural feature. A poorly installed skylight becomes a perpetual leak source and maintenance headache. The difference is entirely in the installation technique, flashing system, and waterproofing details. At Chicago Roofing Team, our skylight installations carry a leak-free guarantee because we refuse to cut corners on the details that prevent water intrusion.

We install VELUX and Fakro skylights — the two most trusted brands in the industry. Both offer energy-efficient Low-E glass, built-in blinds options, solar-powered venting, and engineered flashing systems designed for specific roof types and pitches. We size and position each skylight based on the room it serves, the roof orientation, and the aesthetic goals for both interior and exterior appearance.

Skylight services we provide: New skylight installation (fixed, manual venting, solar-powered venting, and electric venting models), skylight replacement (upgrading old skylights to modern energy-efficient units), skylight flashing repair (the most common source of skylight leaks), sun tunnel installation (tubular skylights for spaces where a traditional skylight isn't feasible), and skylight blind and shade installation. Every installation includes a manufacturer-engineered flashing kit and our workmanship warranty.

⚙ Mission Briefing

Installation Protocol

Precision cuts and watertight flashing — zero margin for error.

Site Planning

Determine optimal size, position, and type. Verify rafter spacing, check for obstructions (wiring, plumbing, HVAC), and plan the interior light shaft if needed.

Roof Opening

Precision cut through roofing material and decking between rafters. Headers installed if opening spans more than one rafter bay. Clean, square opening critical.

Unit & Flashing

Skylight unit set and secured. Manufacturer-engineered step flashing, counter flashing, and saddle flashing installed in the correct sequence for watertight performance.

Interior Finish

Light shaft framed, insulated, and drywalled. Interior trim installed. Every detail completed to a finished standard — not left rough.

❓ Skylight FAQ

Common Questions

A quality skylight installation (including the unit, flashing, interior light shaft, and finishing) typically costs $1,800-$4,500 depending on size, type (fixed vs. venting), and interior finish requirements. Replacement of an existing skylight is less expensive since the opening and light shaft already exist — typically $1,200-$2,500.

Not if installed correctly. Skylight leaks are almost always an installation issue, not a product defect. Our installations use manufacturer-engineered flashing systems and follow a specific installation sequence that creates multiple overlapping waterproof barriers. We guarantee leak-free performance.

For rooms that benefit from ventilation (bathrooms, kitchens), a solar-powered venting skylight is ideal — it opens to release hot air and moisture. For other rooms, a fixed skylight provides the same natural light at lower cost. We recommend Low-E glass for energy efficiency in Chicago's climate.

Skylights can be installed on most roof types and pitches. Minimum recommended pitch is 3:12. We verify structural feasibility — rafter spacing, attic obstructions, and roof geometry — during the planning phase. Some situations may require a sun tunnel (tubular skylight) instead of a traditional unit.
