Professional Skylight Services in Connecticut
A skylight is one of the most impactful upgrades available to a Connecticut homeowner — natural light transforms the feel of a space in a way that no artificial lighting can replicate. But a skylight is also a penetration through the most critical waterproofing layer of the building: the roof. In Connecticut's climate, where freeze-thaw cycles, heavy snowfall, and sustained rain events test every roofing detail, the quality of the skylight installation determines whether the project is a lasting improvement or an ongoing source of water infiltration and heat loss. Sergios Roofing installs and replaces skylights on Connecticut properties with the waterproofing detail and flashing precision that Connecticut's climate demands.
Skylight Installation for Connecticut Homes and Businesses
New skylight installation in Connecticut requires selecting the correct product, sizing the structural opening in the roof framing, installing the curb or deck-mount frame with proper flashing, and integrating the installation with the existing roofing system. Each step must account for Connecticut's snow loads, ice dam potential, and the freeze-thaw cycling that stresses every roofing penetration through the winter months.
Sergios Roofing installs fixed skylights, venting skylights, tubular daylighting devices, and commercial roof glazing systems on Connecticut properties. We work with major skylight manufacturers and follow manufacturer installation protocols to preserve the product warranty. The flashing kit included with or specified for a skylight must be installed exactly as designed — field-improvised flashing is the most common cause of skylight leaks on Connecticut properties.
The structural opening for a skylight must be properly framed and supported before the skylight unit is installed. We assess the existing rafter spacing, install headers and trimmer rafters as required by the opening size and Connecticut building code, and confirm that the opening is square and properly supported before the curb or deck-mount frame goes in. Interior finish work — drywall, trim, and light shaft framing — is coordinated with the exterior installation to complete the project.
Skylight Replacement and Leak Repair in Connecticut
Skylight replacement is one of the most common roofing projects we perform on Connecticut homes. Older skylights — particularly those installed more than 15 to 20 years ago — were built to lower performance standards than current products and frequently develop seal failures, condensation between panes, and flashing deterioration that leads to leaks. In many cases, the skylight itself is still structurally sound but the original flashing installation has failed after years of Connecticut freeze-thaw cycling.
When a Connecticut homeowner reports a skylight leak, Sergios Roofing begins with a thorough inspection to diagnose the source. Skylight leaks can originate at the glass-to-frame seal, at the step flashing along the sides of the curb, at the head flashing where the skylight meets the upper roof surface, or at the sill flashing at the lower edge. Each failure point requires a different repair approach, and misdiagnosing the source leads to repairs that do not solve the problem.
We replace complete skylight units when the original product has failed beyond repair, installing new units with manufacturer-specified flashing kits and ice and water shield at all transition points. For Connecticut properties where the existing skylight is performing but the surrounding roofing material is being replaced, we assess whether the existing flashing can be reused or must be replaced to match the new roofing system being installed.
Why Skylight Waterproofing Quality Matters in Connecticut
Connecticut's climate creates specific challenges for skylight installations that do not exist in more moderate climates. Ice dams that form at the eave can back up under roofing materials and reach skylight openings, forcing water into the building through flashing joints that would otherwise be watertight. Snow loads that accumulate against a skylight curb create hydrostatic pressure at the perimeter flashing that reveals any weakness in the original installation.
A properly installed Connecticut skylight includes ice and water shield applied beneath the step flashing on both sides of the opening, ice and water shield at the sill beneath the apron flashing, and a continuous ice and water shield strip at the head extending at least 24 inches up the roof from the top of the skylight frame. This detail is required by Connecticut building code for all roof penetrations and is the single most important factor in long-term leak prevention.
Sergios Roofing installs every Connecticut skylight with full ice and water shield perimeter protection, manufacturer-specified flashing kits, and proper integration with the adjacent roofing system. We have repaired and replaced enough poorly installed skylights on Connecticut properties to understand exactly what the installation must include to perform reliably through the full range of Connecticut seasonal conditions. Our 20 years of experience on Connecticut roofs informs every decision we make on a skylight installation.
