Bringing More Natural Light Into Your Home

Choosing The Right Skylight For Each Room

Different rooms benefit from different skylight configurations. Fixed skylights are well suited for living rooms, stairwells, and vaulted ceilings where additional daylight is the priority, while venting skylights provide natural ventilation for kitchens, bathrooms, and upper-floor spaces where excess heat and humidity commonly accumulate.

Modern Glazing Improves Comfort & Energy Efficiency

Today's skylights feature insulated double- or triple-pane glazing with Low-E coatings and argon gas-filled cavities to reduce heat transfer throughout the year. These glazing technologies help maximize natural light while limiting winter heat loss, reducing summer solar gain, and improving overall indoor comfort in Thunder Bay's changing climate.

Proper Placement Maximizes Natural Daylight

The amount of daylight entering a home depends on more than skylight size alone. Roof orientation, roof pitch, room dimensions, ceiling height, shaft depth, and interior surface reflectivity all influence how natural light is distributed. Careful placement helps create bright, comfortable living spaces without introducing excessive glare.

Integrating Skylights Into Existing Roofing Systems

Every skylight installation must work seamlessly with the surrounding roof assembly. We integrate the skylight with the existing shingles or metal roofing, underlayment, flashing system, and roof framing to maintain continuous weather protection while preserving the performance and appearance of the overall roofing system.

Proper Flashing Protects Against Snow & Ice

Factory Flashing Kits Create A Reliable Waterproof Seal

Modern skylights are designed to work with manufacturer-specific flashing kits that integrate with the surrounding roofing materials. Head flashing, sill flashing, step flashing, and side flashings direct water safely around the skylight opening, reducing the risk of leaks during heavy rainfall and spring snowmelt.

Ice & Water Shield Adds Critical Winter Protection

Because skylights interrupt the roof surface, they require enhanced waterproofing beneath the finished roofing material. Self-adhering ice and water shield is installed around the skylight curb or deck-mounted frame to help prevent water infiltration if melting snow or ice temporarily backs up beneath the shingles during Thunder Bay's winter months.

Roof Pitch Determines Proper Skylight Performance

Every skylight is designed to be installed within a specified roof pitch range. Installing the correct skylight for the roof slope allows water and melting snow to drain efficiently, while ensuring the flashing system functions as intended. Selecting the proper unit helps reduce standing water and improves long-term weather resistance.

Professional Installation Prevents Common Leak Problems

Many skylight leaks result from improper installation rather than the skylight itself. Incorrect flashing integration, missing underlayment, inadequate fastening, poorly sealed roof penetrations, or improper shingle sequencing can all allow moisture to enter the roofing system. Following manufacturer-approved installation procedures helps provide durable, leak-free performance for years to come.

Replacing Aging Or Leaking Skylights

Recognizing When A Skylight Has Reached The End Of Its Service Life

Older skylights can develop failed glazing seals, cracked acrylic domes, deteriorated gaskets, warped frames, or worn flashing that compromise their performance. Signs such as persistent condensation between glass panes, recurring leaks, drafts, or visible frame deterioration often indicate that replacement is a more reliable long-term solution than repeated repairs.

Upgrading To Modern Energy-Efficient Skylights

Replacing an older skylight provides the opportunity to install newer models with insulated Low-E glass, argon-filled glazing, thermally broken frames, UV protection, and improved weather seals. These advancements help reduce heat loss during winter, improve indoor comfort, and enhance the skylight's overall energy performance compared to older designs.

Coordinating Skylight Replacement With Roof Replacement

Replacing skylights during a complete roof replacement is often the most efficient approach. With the existing roofing materials already removed, new underlayment, ice and water shield, flashing systems, and roofing materials can be integrated seamlessly around the skylight, reducing labour while helping ensure long-term weatherproofing and warranty compliance.

Ensuring The New Skylight Fits Your Existing Roof Structure

Every replacement project begins by confirming roof framing, rough opening dimensions, roof pitch, and shaft configuration. Selecting a skylight that properly fits the existing structure minimizes structural modifications, simplifies installation, and helps ensure the new unit integrates correctly with the surrounding roofing system for dependable long-term performance.

Skylight FAQs

Deck-mounted skylights with insulated Low-E, argon-filled glass and manufacturer-designed flashing systems are well suited to Northwestern Ontario's climate. When installed with ice and water shield and proper underlayment, they provide excellent resistance to snow, ice, and seasonal temperature fluctuations while maintaining energy efficiency.

Not always. Leaks caused by damaged flashing or worn roofing materials around the skylight can often be repaired. However, if the skylight has a failed insulated glass seal, cracked frame, deteriorated gaskets, or has reached the end of its service life, replacement is generally the more reliable long-term solution.

Modern skylights are significantly more energy efficient than older models. Double- and triple-pane insulated glazing, Low-E coatings, argon gas, and thermally broken frames help minimize heat transfer. When professionally installed and properly air sealed, a quality skylight has only a limited impact on overall home heat loss.

Leading residential skylight manufacturers include VELUX, Fakro, and Wasco, all of which offer products with integrated underlayment systems, prefabricated flashing kits, insulated glazing options, and models designed for various roof pitches. Choosing a reputable manufacturer helps ensure long-term performance, replacement part availability, and strong warranty support.
