Flashing Repairs and Skylight Resealing for Long-Term Waterproofing
In 90% of cases, skylight leaks are caused by compromised flashing or inadequate waterproof detailing. At Sydney Roofers, we repair or replace defective skylight flashings using custom Colorbond®, Zincalume®, or lead-free alternatives. We remove deteriorated apron flashings, rusted step flashings, or cracked storm collars and replace them with precision-cut profiles designed to fit your roof’s pitch, cladding material, and skylight model.
All new flashings are integrated into the existing roof structure to meet or exceed AS/NZS 3500 and NCC codes for moisture management. We reseal exposed joints with UV-stable polymers and ensure all drainage paths remain clear and correctly sloped to prevent ponding or water backup under the roof membrane. Our repair techniques ensure compliance with manufacturer warranties and extend the lifespan of your existing skylight system.
Repairing Skylight Leaks Around Tiled and Metal Roof Penetrations
Leaks around skylights on tiled and metal roofs often go unnoticed until visible stains appear on internal ceilings. Our specialists inspect tile bedding, underlayment condition, and flashing interfaces to isolate the source of ingress. On tiled roofs, we lift and relay tiles around the skylight and rebed ridge caps or side flashings as needed. On metal roofs, we replace failing flashings and reseal fixings using high-grade weatherproof gaskets and adhesives to restore full watertight performance.
Replacing Cracked Skylight Domes and Damaged Glazing Panels
Cracks, warping, or UV degradation in older acrylic or polycarbonate skylights can lead to slow water ingress and loss of insulation. We replace broken or yellowed skylight domes and glazing units with modern double-glazed or high-impact acrylic models that improve thermal control, reduce noise, and comply with modern safety codes. All replacements are installed with perimeter flashing integration and sealed against thermal expansion to prevent future fractures or leaks.
Fixing Skylight Condensation and Internal Mould Issues
Condensation inside skylight cavities can lead to moisture pooling, frame decay, and visible mould along ceilings or plasterboard. We assess internal vapour barriers, ventilation conditions, and frame insulation to resolve these issues. Where necessary, we upgrade internal linings and install thermal break flashing or insulated curb extensions to mitigate condensation buildup. These measures restore healthy airflow and reduce long-term humidity damage inside the roof space.
Resealing and Reflashing Velux, Fakro and Custom Skylight Units
Premium roof window systems like Velux and Fakro also suffer from leaks when original flashing kits deteriorate or were not installed per manufacturer guidelines. Our team provides full resealing and reflashing of operable skylights, using brand-specific kits or custom flashings fabricated to match pitch and frame dimensions. We realign fixings, re-anchor the curb or reveal, and integrate counterflashing to protect against wind-driven rain and thermal movement that typically causes joint separation.
At Sydney Roofers, we take skylight repair seriously — because we know that even a small leak can lead to costly internal damage and disrupted living conditions. Our skylight repair services combine precision leak detection, advanced waterproofing, and long-term flashing solutions that exceed Australian compliance standards. Whether your skylight is cracked, leaking around the flashing, or allowing condensation to form inside, we’ll restore its integrity with minimal disruption and maximum durability. Contact us today for fast, professional skylight repairs across Greater Sydney and surrounding suburbs.
Emergency Skylight Leak Repairs and On-Roof Diagnosis
Sudden leaks during storms or high rainfall are common around skylight penetrations — particularly when flashings have failed or were installed incorrectly. Our team provides same-day leak investigation, emergency skylight sealing, and temporary protection for urgent water ingress scenarios. Using thermal imaging and moisture detection where needed, we identify the exact point of water entry and distinguish between surface leaks, flashing failures, and internal condensation buildup.
Once identified, we remove defective sealants or corroded flashings, clean and dry the surrounding roof substrate, and reinstall or reseal using polyurethane-based waterproofing compounds. For metal roofing or membrane-sealed surfaces, we integrate custom bent metal flashings and storm-resistant overlays. For tiled roofs, we reset surrounding tiles, repoint ridge cappings, and embed step flashing where needed to direct water flow correctly and protect vulnerable joints.
