A skylight is more than a design feature. When properly installed, it enhances natural light, improves interior comfort, and increases property value without sacrificing the performance of your roofing system. When installed incorrectly, however, a skylight becomes one of the most vulnerable points on a roof. The difference comes down to installation precision, flashing integration, and proper waterproofing.

Skylight installation and replacement must be approached as a structural modification to the roofing system, not an accessory add-on. Every opening in a roof requires controlled reinforcement, correct underlayment layering, and careful flashing sequencing to maintain long-term watertight integrity. At Aucoin Roofing, our team includes multiple Velux Certified Installers, ensuring every skylight is installed according to strict Velux installation standards. This allows us to deliver a system that performs as intended, protecting both the roofing assembly and the interior space below. The result is increased natural light, improved energy efficiency, and long-term reliability without unnecessary risk.

Not every space in a home is ideal for a full skylight. That’s where VELUX Sun Tunnel® Skylights come in. A Sun Tunnel® is a type of tubular skylight designed to bring natural daylight into areas where a traditional skylight may not fit.

These systems capture sunlight through a small dome installed on the roof and direct that light down a highly reflective tube into the room below. The result is bright, natural daylight in spaces that would otherwise rely on artificial lighting.

Sun Tunnel® Skylights are a popular solution for areas such as hallways, bathrooms, closets, and interior rooms where windows or larger skylights aren’t practical. They can often be installed quickly and provide an efficient way to brighten darker areas of the home.

The team at Aucoin Roofing installs high-quality skylight systems designed for long-term performance. With Velux Certified Installers on staff, each system is installed according to manufacturer standards, helping homeowners bring more natural light into their homes without major structural changes.

A skylight creates an opening in the roofing system, making proper flashing and underlayment essential. Step flashing must be integrated precisely to direct water away from the opening. Poor installation can lead to hidden moisture damage in insulation and decking. We ensure every skylight is integrated into the roofing system not treated as a weak point.

Ventilation planning is equally critical. Without balanced airflow, skylights can contribute to condensation buildup. We assess intake and exhaust systems to maintain proper airflow. Aucoin Roofing carries full WSIB and liability coverage, and our in-house team ensures consistent workmanship and long-term performance.

Skylight performance depends on selecting the right product and installing it as part of the roofing system not separate from it:

• Fixed & Venting Skylights: Fixed skylights provide consistent daylight with minimal mechanical components, making them ideal for living spaces and hallways. Venting skylights offer controlled airflow, improving indoor comfort and ventilation efficiency when properly integrated into attic airflow planning.
• Energy-Efficient Glass Systems: We install double- and triple-glazed skylight units designed to reduce heat transfer and UV penetration. Low-E coatings and insulated glass assemblies enhance interior comfort while maintaining energy efficiency.
• Flashing Kit Integration & Roof Compatibility: Every skylight is paired with manufacturer-specific flashing systems compatible with the existing roofing material. Whether asphalt shingle, metal, or low-slope membrane, flashing integration is treated as a structural waterproofing assembly.
• Replacement & Upgrade Services: Aging skylights often fail at the seal or flashing junction rather than the glass itself. We remove outdated units, repair surrounding roofing components, and install modern replacements that meet current performance standards.

Every skylight project follows a structured process designed to eliminate guesswork and ensure durability.

1. Structural Assessment & Placement Planning: We evaluate roof pitch, framing layout, and attic configuration to determine optimal skylight placement. Proper positioning ensures structural integrity while maximizing natural light distribution.
2. Controlled Roof Opening & Framing Reinforcement: The roof opening is precisely measured and cut. We reinforce framing where required to maintain load distribution and prevent structural stress around the new penetration.
3. Waterproofing Layer Integration: High-performance underlayment and ice-and-water protection membranes are installed around the opening before the skylight is set. This layered approach ensures water is directed away from vulnerable seams.
4. Precision Flashing & Skylight Installation: We install manufacturer-approved flashing kits that integrate seamlessly with surrounding shingles or roofing materials. Proper sequencing of step flashing and counter flashing prevents future leak points.
5. Final Seal, Inspection & Interior Review: We complete a full system inspection to confirm watertight performance and proper alignment. Interior finishes are reviewed to ensure clean integration and structural stability.

A properly installed unit enhances interior spaces without compromising roof durability or energy efficiency. A poorly installed unit becomes a recurring maintenance issue. At Aucoin Roofing, skylight installation and replacement are treated as engineered modifications to the roofing envelope. We prioritize watertight integrity, structural reinforcement, and manufacturer-certified installation standards so your investment delivers natural light without structural risk.
