A skylight can dramatically change the feel of a room by adding natural light and making interior spaces feel more open. But for a skylight to be a benefit, it must be installed properly as part of the roofing system. If corners are cut, a skylight can become a common source of leaks, moisture issues, and avoidable roof problems. The difference comes down to correct placement, strong waterproofing, proper flashing, and installation methods that protect the roof over the long term.

At Aucoin Roofing, we provide skylight installation and skylight replacement in Cambridge with a focus on both daylighting and structural protection. A skylight is not just an accessory added to the roof. It is an opening in the roofing assembly, which means every surrounding detail needs to be planned and installed carefully. Our team includes VELUX Certified Installers, and we install skylights according to manufacturer standards that support watertight performance, energy efficiency, and long-term reliability.

For a skylight to perform properly, the roofing system around it must be built correctly. Flashing details, underlayment layers, framing support, roof compatibility, and airflow considerations all affect whether the skylight will remain watertight and stable over time. If those parts are not handled with care, water can enter around the unit and begin affecting insulation, decking, and interior finishes.

That is why Aucoin Roofing treats skylight installation as a technical roofing project, not just a finishing upgrade. We evaluate roof pitch, attic conditions, framing layout, and ventilation needs before the work begins so the skylight is positioned and installed correctly. Flashing and waterproofing components are then integrated in the right sequence to help protect the surrounding roof from future problems. Every skylight project is completed by our in-house team, and Aucoin Roofing is fully licensed, insured, and WSIB compliant.

Each skylight project should be chosen and installed based on the layout of the home, the roof structure, and the function of the interior space. At Aucoin Roofing, we provide skylight solutions designed for strong performance, clean appearance, and dependable long-term results.

Fixed & Venting Skylights:

Fixed skylights are a strong option for bringing steady natural light into living rooms, kitchens, hallways, and open interior spaces. Venting skylights can also improve airflow and indoor comfort when installed as part of a properly planned 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:

When an older skylight begins to fail, the issue is often with the seal, flashing, or roof integration rather than the glass alone. We replace aging skylights and repair surrounding roof components so the new unit performs properly.

Skylights in Cambridge have to hold up through weather conditions that can put pressure on roof systems year after year. Rainfall, snow, humidity, winter freeze-thaw movement, and summer heat all affect how the roof and skylight work together. That is why skylight installation in Cambridge needs to be approached with long-term water control and roofing performance in mind, not just interior appearance.

Some Cambridge homes may have more complex rooflines, older framing conditions, attic ventilation issues, or existing skylights that need a more careful replacement approach. Others may be better suited to smaller daylighting systems such as Sun Tunnel® skylights depending on the space below. At Aucoin Roofing, each Cambridge skylight project is planned around the home, the roof structure, and the local conditions the property faces so the finished result brings in light without creating future roofing issues.

Every skylight project follows a structured system to ensure long-term performance, not short-term patchwork.

1.Structural Assessment & Placement Planning: We assess the roof pitch, attic layout, and framing structure to identify the right placement for the skylight while protecting structural integrity and maximizing daylight.
2.Controlled Roof Opening & Framing Reinforcement: The roof opening is measured and cut carefully, and reinforcement is completed where needed to maintain proper support around the unit.
3.Waterproofing Layer Integration: Protective underlayments and waterproofing membranes are installed around the opening before the skylight is positioned to help defend against moisture intrusion.
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.
