Skylight Installation & Replacement in Saint John, NB | Leak-Free Natural Lighting
Saint John Roofing has over 20 years of experience providing residential skylight installation and replacement services throughout Saint John, NB. We install deck-mounted and curb-mounted skylights using manufacturer-approved flashing systems, insulated Low-E glazing, argon-filled glass and precision roof opening preparation to deliver reliable natural lighting while maintaining a watertight roofing system.
A properly installed skylight depends on far more than cutting an opening in the roof. We carefully prepare rough openings, construct insulated light shafts where required and integrate step flashing, head flashing, sill flashing and manufacturer flashing kits into the surrounding roofing materials. We install fixed and venting skylights from trusted manufacturers such as VELUX and Fakro, ensuring every component works together to resist water intrusion and provide long-term performance.
We install and replace residential skylights throughout Rothesay, Quispamsis, Grand Bay-Westfield, Hampton, Sussex, St. Martins, Norton, Kingston Peninsula, Cambridge-Narrows, Gondola Point, Nauwigewauk, Browns Flat and surrounding southern New Brunswick communities.

Bringing More Natural Light Into Your Home
Choosing Between Fixed And Venting Skylights
Fixed skylights are designed solely to introduce natural daylight, making them ideal for living rooms, hallways and stairwells where additional ventilation is unnecessary. Venting skylights can be opened manually or electrically to provide both daylight and fresh air, making them well suited for kitchens, bathrooms and vaulted spaces where excess heat or humidity may accumulate.
Selecting The Right Skylight Configuration
Residential skylights are available in both deck-mounted and curb-mounted designs, with the appropriate option depending on the roof structure, roof pitch and roofing material. Determining the correct mounting method during the planning stage helps ensure the skylight integrates properly with the surrounding roof while supporting long-term weather resistance.
Maximizing Daylight With Proper Placement
The amount of natural light entering a home depends on more than the size of the skylight. Roof orientation, ceiling height, room dimensions, shaft depth and the reflectivity of interior finishes all influence how daylight is distributed throughout the space. Careful placement helps deliver balanced natural lighting while minimizing excessive glare during different times of the day.
Improving Energy Performance With Modern Glazing
Today's residential skylights incorporate advanced glazing technologies that improve comfort throughout the year. Low-E coated glass helps reduce unwanted solar heat gain while allowing visible light to pass through, argon-filled insulated glazing improves thermal performance between glass panes, and laminated glass enhances safety by remaining intact if damaged. Together, these features increase energy efficiency while providing bright, comfortable natural daylight.
Protecting Skylights From Wind-Driven Rain
Integrating Manufacturer Flashing Systems
A skylight is only as reliable as the flashing that surrounds it. Manufacturer-designed flashing kits use step flashing, head flashing and sill flashing that are engineered to work with specific skylight models and roofing materials. Proper integration with the surrounding shingles creates overlapping drainage paths that direct water safely away from the skylight opening.
Building A Watertight Roof Opening
Creating a roof opening requires more than cutting through the roof deck. The rough opening must be accurately framed, waterproofed and protected with underlayment before the skylight is installed. Careful preparation helps prevent water infiltration around the skylight while maintaining the structural integrity of the surrounding roof assembly.
Managing Heavy Rainfall On Sloped Roofs
Saint John's coastal climate frequently brings prolonged rainfall and wind-driven storms that place additional demands on skylight installations. Proper roof pitch, flashing placement and water-shedding details allow rainwater to flow around the skylight instead of collecting against its perimeter. These design considerations help reduce the risk of leaks during severe weather.
Protecting Roofing Materials Around The Skylight
The roofing materials surrounding a skylight experience concentrated water flow throughout the year. Correctly installing shingles, underlayment and flashing around the skylight prevents exposed joints and weak transition points from developing over time. Maintaining these critical connections helps preserve both the skylight installation and the performance of the surrounding roofing system.
Replacing Aging, Inefficient Or Leaking Skylights
- Recognizing When A Skylight Has Reached The End Of Its Service Life
Like any exterior building component, skylights eventually deteriorate after years of exposure to sunlight, temperature fluctuations and severe weather. Clouded glazing, worn weather seals, deteriorated frames, recurring condensation between glass panes and persistent water intrusion are common signs that replacement may be more practical than continued repairs.
- Upgrading To Modern Energy-Efficient Skylights
Older skylights often use glazing technology that provides significantly lower thermal performance than modern units. Replacing them with Low-E, argon-filled insulated glass helps reduce unwanted heat transfer while allowing abundant natural daylight into the home. These upgrades improve year-round comfort without sacrificing the brightness homeowners expect from a skylight.
- Installing A New Skylight Without Compromising The Roof
Replacing an existing skylight provides the opportunity to renew critical waterproofing components around the roof opening. New manufacturer flashing kits, underlayment integration and properly prepared rough openings help ensure the replacement skylight becomes part of the roofing system rather than a potential point of water intrusion. Careful installation protects both the new skylight and the surrounding roof.
- Selecting A Replacement That Fits Your Existing Roof
Not every replacement skylight is identical to the original unit. Roof pitch, opening dimensions, shaft configuration, glazing options and mounting style all influence which replacement model is appropriate. Choosing a skylight designed for the home's existing roof structure helps simplify installation while maximizing long-term weather performance and natural lighting.
Skylight Installation & Replacement FAQs
What is the difference between a deck-mounted and curb-mounted skylight?
A deck-mounted skylight is fastened directly to the roof deck, creating a lower-profile appearance that is commonly used on sloped residential roofs. A curb-mounted skylight is installed over a raised, site-built curb that projects above the roof surface. The appropriate option depends on the roof design, roof pitch, roofing material and the manufacturer's installation requirements.
Why are manufacturer flashing kits important when installing a skylight?
Manufacturer flashing kits are engineered specifically for each skylight model and roof pitch. They combine step flashing, head flashing and sill flashing with waterproof underlayment to create an integrated drainage system around the skylight opening. Using the correct flashing kit helps reduce the risk of water infiltration and ensures the skylight performs as intended under normal weather conditions.
Can modern skylights improve energy efficiency?
Yes. Modern skylights commonly feature insulated double glazing with Low-E coatings and argon-filled glass that reduce heat transfer while allowing natural daylight into the home. These technologies help improve thermal performance compared to older skylights and contribute to more consistent indoor comfort throughout the year.
Can an existing skylight be replaced without changing the entire roof?
In many cases, yes. If the surrounding roofing materials remain in good condition, an aging skylight can often be replaced independently of a full roof replacement. During the replacement, the existing roof opening, flashing details and adjacent roofing materials are evaluated to ensure the new skylight can be integrated without compromising the roof's weather resistance.
