Preventing Future Leaks and Water Damage
Properly installed flashing around skylights creates a criticalwater-tight barrier between the roof surface and window frame. Weatherbarrier materials must be integrated with the roof's waterproofingsystem to direct water away from vulnerable seam points. Older skylightseal materials degrade over time, increasing the risk of leaks even when the surrounding roof remains in good condition.
Proper Flashing Installation
Achieving a watertight seal around skylights depends primarily onproper flashing installation. The process requires specific componentsworking together: apron flashing at the lower edge overlapping shingles, head flashing above the skylight tucked under the next shingle course,and side flashing completing the seal.
Installation begins with removing old materials, then preciselyplacing bottom flashing against the curb. After positioning the skylight unit, installers must apply roofing cement at critical junctions foradditional protection. The top flashing must extend under shingles withproper spacing above the curb.
Common errors include incorrect flashing placement, insufficientsealant application, and poor-quality materials. Regular maintenanceinvolves inspecting for rust or deterioration, clearing debris, andreapplying sealants as needed. For complex installations, professionalassistance is recommended to guarantee long-term waterproofing success.
Weather Barrier Protection
Why do some skylights leak after a roof replacement while othersremain watertight for decades? The difference often lies in properweather barrier implementation. High-quality ice and water barriers like Owens Corning's WeatherLock Flex provide vital protection against water infiltration beneath the skylight flashing.
Effective vapor barriers prevent moisture issues that lead towarping, rotting, and mold growth. Self-sealing properties in premiumbarriers guarantee fastener penetrations remain watertight. Proper roofdeck protection creates multiple defense layers, preventing water fromreaching the skylight opening.
Regular inspections identify potential moisture problems beforesignificant damage occurs. The condition of weatherproof seals must beverified during roof replacement, as disrupted seals are a primary cause of post-replacement leaks. Early detection of moisture issues iscritical, as damage can develop within one year of improper skylightintegration.
Seal Degradation Risk
Skylight seal degradation represents one of the most common failurepoints leading to leaks and water damage after roof replacements. Sealsdeteriorate through normal aging, temperature fluctuations, and exposure to environmental elements like rain, snow, and debris. Evenhigh-quality skylights typically require replacement every decade due to inevitable seal degradation.
Improper installation greatly accelerates seal failure, creatingimmediate vulnerabilities in the roof system. When water infiltratesthrough compromised seals, it can cause extensive structural damage,promote mold growth, and rot wooden components. These issues oftenremain undetected until considerable damage has occurred. Professionalinstallation, regular inspections, and using premium materials canmitigate these risks. Including skylight replacement in roof replacement projects guarantees properly integrated flashing and seals, preventingcostly repairs later.
