Skylights & Sun Tunnel Installation in St. George, Ontario
Natural light can completely change the feel of a home. A well-placed skylight can brighten darker areas, make rooms feel more open, and improve the overall comfort of the living space. But because a skylight creates an opening in the roof, it also needs to be installed with a high level of care. If the surrounding roof details are not handled properly, a skylight can become a source of leaks, condensation issues, and avoidable roofing problems.
At Aucoin Roofing, we provide skylight installation and skylight replacement in St. George with a strong focus on roof integrity, waterproofing, and long-term performance. We do not treat a skylight as a simple finishing feature. It has to be integrated correctly into the roofing system so it performs as intended without compromising the roof around it. Our team includes VELUX Certified Installers, and every skylight is installed to manufacturer standards designed to protect both the roof above and the living space below.
What Makes a Metal Roof Perform Well Over Time
A long-lasting steel roof depends on more than the shingles themselves. The roof deck, underlayment, flashing, fastening pattern, and attic ventilation all play a role in how well the system performs over time. If one of those details is overlooked, the roof may not deliver the full lifespan or protection homeowners expect from a premium metal roofing system.
That is why Aucoin Roofing installs metal roofing as a complete assembly rather than a simple material swap. Before installation begins, we review the roof structure, decking condition, ventilation layout, and critical roof details so the new system starts on a solid foundation. We also pay close attention to areas like valleys, chimneys, skylights, ridges, and wall transitions, since these are key points in long-term water management. All work is completed by our in-house crews, and Aucoin Roofing is fully licensed, insured, and WSIB compliant.
Skylight Installation Specializations
Every steel roofing project should fit the home, the roofline, and the goals of the homeowner. At Aucoin Roofing, we install metal roofing systems designed for lasting protection and a clean finished appearance.
Fixed & Venting Skylights:
Fixed skylights are a strong option where added daylight is the main goal. Venting skylights can also improve airflow and comfort when integrated properly into the roofing and ventilation system.
VELUX Sun Tunnel® Skylights:
Not every room is suited for a full skylight. Sun Tunnel® skylights are an ideal solution for hallways, closets, bathrooms, and other interior spaces where a larger unit may not fit. These systems capture daylight at the roof level and direct it through a reflective tunnel into the room below, bringing natural light into darker spaces without major structural disruption.
Energy-Efficient Skylight Systems:
We install modern skylight units designed with insulated glass, Low-E coatings, and performance-focused glazing options that help reduce heat transfer while improving comfort and efficiency inside the home.
Skylight Replacement & Upgrades:
Older skylights often fail at the seal, flashing junction, or surrounding roof connection rather than at the glass alone. We remove aging skylights, inspect and repair the surrounding roof area, and install updated replacement systems that meet current installation and performance standards.

Built to Handle St. George Weather
Roofs in St. George need to perform through snow, rain, humidity, wind, and repeated seasonal temperature changes. Those conditions put pressure on the roofing material itself, but also on the supporting details that make the full system work. A metal roof needs to do more than simply resist wear. It needs to be installed in a way that allows it to keep protecting the home year after year under local conditions.
Many homes in St. George are detached houses where roof design, lot exposure, and architectural details can vary more than they would in a denser urban setting. Some properties may have more detailed rooflines, skylights, chimneys, or transitions that require added care during installation. Others may need ventilation improvements or updated flashing as part of the overall roofing system. At Aucoin Roofing, each metal roofing project is tailored to the home, the roof layout, and the conditions the property faces so the finished system delivers dependable long-term performance.
The Aucoin Signature 5-Step Process
Every skylight project follows a structured system to ensure long-term performance, not short-term patchwork.
1.Structural Assessment & Placement Planning: We review the roof pitch, framing layout, and attic configuration to determine the best location for the skylight while maintaining structural stability and maximizing natural light.
2.Controlled Roof Opening & Framing Reinforcement: Once the placement is confirmed, the roof opening is measured and cut with precision. Where needed, framing is reinforced to maintain load support and prevent unnecessary stress around the new skylight opening.
3.Waterproofing Layer Integration: High-performance underlayments and protective membrane layers are installed around the skylight opening before the unit is set in place. This step helps ensure water is directed away from seams and vulnerable transitions, which is especially important for long-term Norfolk County skylight replacement and installation performance.
4.Precision Flashing & Skylight Installation: We install manufacturer-approved flashing kits that integrate properly with the surrounding roofing material. Whether the roof system is asphalt shingle, metal, or another compatible material, flashing is installed in the correct sequence to protect against future leaks.
5.Final Seal, Inspection & Interior Review: Once the skylight has been installed, we complete a full final inspection to confirm watertight performance, proper alignment, and clean integration into the roof structure. Interior finishes and transitions are reviewed so the finished skylight system looks right and performs the way it should.

Frequently Asked Questions
Because the quality of the installation matters just as much as the skylight itself. A skylight creates an opening in the roof, so proper flashing, waterproofing, and integration with the surrounding roofing system are critical. Aucoin Roofing has VELUX Certified Installers on staff, which means the work is completed according to manufacturer standards designed to support long-term performance and reduce the risk of future leaks.
Yes. Skylights can often be installed on both newer and older homes, but the roof structure, roof pitch, and surrounding roofing condition all need to be assessed first. Older homes may have framing, ventilation, or roofing details that need more careful review before the work begins. At Aucoin Roofing, we assess the existing roof system before recommending the best skylight solution for the home.
Skylights work especially well in kitchens, bathrooms, hallways, laundry rooms, and upper-level living spaces that do not get enough natural light from wall windows alone. In some homes, a full skylight is the best fit, while in others a VELUX Sun Tunnel® may make more sense for a smaller or more enclosed area. At Aucoin Roofing, we help homeowners choose the right daylighting option based on the room, the roof layout, and the amount of light they want to bring in.
In many cases, yes. Skylights can be a great way to bring more natural light into darker areas of the home, improve the feel of a space, and make rooms feel more open. The key is making sure the skylight is installed properly and matched to the roof structure. At Aucoin Roofing, we treat skylights as part of the roofing system, so the goal is not just added light, but long-term performance as well.
