Skylight Leaking When Raining in Hattiesburg – Stop Water Damage Before It Spreads Through Your Ceiling

Homeowners insurance covers roof leaks from sudden, accidental storm damage like hail impact or falling tree limbs. It does not cover leaks from wear and tear, deferred maintenance, or aging materials. If a storm damages your skylight flashing or cracks the glazing, your policy will cover repairs minus your deductible. If the leak results from a 15-year-old seal that finally gave out, you pay out of pocket. Document the damage with photos immediately after the storm. File your claim within your policy's timeframe. An adjuster will inspect and determine if the damage qualifies as a covered peril.

No, not all skylights leak, but poorly installed or unmaintained ones will. Quality skylights with properly installed step flashing, counterflashing, and ice and water shield can last 20 years without leaking. The problem is installation errors. Many roofers cut corners on flashing details or use incorrect sealants. Skylight curbs that are not built to manufacturer specs allow water infiltration. Regular maintenance matters. Inspect flashing annually, clear debris from the uphill side, and reseal when you notice cracks. Flat roof skylights are more prone to leaks because water pools instead of shedding. Choose curb-mounted units over deck-mounted for better drainage and flashing redundancy.

No, you cannot apply most roof sealants in the rain. Sealants require a dry substrate to bond. Water prevents adhesion and the sealant will peel off within days. Even moisture from humidity can compromise the cure. If you must make an emergency stop during a storm, use a tarp or waterproof patch tape designed for wet conditions. Once the rain stops, wait for the surface to dry completely before applying polyurethane or silicone sealant. Some emergency wet-surface products exist, but they are temporary. For permanent skylight flashing repairs, dry weather is non-negotiable. Rushing the job in wet conditions wastes money and extends damage.

A roof leak causes damage within 24 to 72 hours. Water spreads through insulation, soaks drywall, and penetrates wood framing. Mold spores colonize damp materials in 48 hours. The longer water sits, the worse the damage. A small skylight drip can rot roof decking, compromise structural integrity, and ruin ceilings and belongings below. You may not see the full extent immediately because water travels along rafters before appearing as a stain. Act the moment you notice a leak. Place a bucket to catch drips, document the damage, and call a roofer. Delaying even a few days turns a $500 flashing repair into a $5,000 decking replacement.

Flex Seal can stop a minor skylight leak temporarily, but it is not a professional repair. Flex Seal works on small cracks in flashing or around the curb if the surface is clean and dry. It will not fix separated step flashing, missing shingles, or structural curb failure. The product degrades under UV exposure and temperature cycling, so expect it to fail within months. Use it only as an emergency stopgap until a roofer can make proper repairs. Applying Flex Seal over dirty or wet surfaces guarantees failure. For long-term skylight waterproofing, replace failed flashing and use roofing cement or polyurethane sealant rated for metal and shingle interfaces.

A quality skylight lasts 20 to 30 years, depending on material and installation. Glass glazing outlasts acrylic, which yellows and cracks after 15 years. Metal flashing and curbs last longer than plastic components. The sealant and gaskets fail first, usually around year 10 to 15, requiring maintenance or resealing. UV exposure, thermal cycling, and storm damage accelerate wear. Flat roof skylights have shorter lifespans due to standing water stress. Inspect your skylight annually for cracks, gaps, and condensation. If your skylight is over 20 years old and leaking, replacement is often more cost-effective than repeated repairs because the entire assembly is nearing end of life.
