How Does Storm Damage Affect Skylights and Roof Penetrations?
Last updated October 23, 2026
The short answer
High Winds Dislodge Flashing and Seals
Strong gusts from storms can physically lift and bend the metal flashing around skylights, vents, and chimneys. This breaks the critical watertight seal between the penetration and the roof deck. Once lifted, the flashing creates a direct channel for water to flow underneath your shingles.
The constant flexing and pulling during a wind event also stresses the caulking and sealants. These materials become brittle over time and can fail completely under strain. A compromised seal allows wind-driven rain to seep in around the edges, often going unnoticed until stains appear on your ceiling.
Hail and Debris Cause Direct Impact Damage
Hailstones can crack or shatter the acrylic dome or glass of a skylight upon impact. Even smaller hail can create pitting and micro-fractures that weaken the material, making future failure more likely. This damage is often immediately visible from inside your home.
Flying debris like tree branches or unsecured patio furniture acts like a projectile. A direct hit can puncture a skylight or dent and tear the flashing around a roof vent. This type of damage creates a large, obvious entry point for large volumes of water during subsequent rain.
- Cracked or shattered skylight glazing
- Dented and torn metal flashing around vents
- Punctures in rubber boots around plumbing pipes
- Dislodged chimney caps or cricket flashings
- Damaged sealant beads around all penetrations
- Granule loss from shingles near the damaged area
Immediate Steps to Take After a Storm
Your first priority is safety. If you see active dripping, place buckets to catch water and move furniture or valuables out of the way. Avoid going onto a storm-damaged roof yourself, as the surface may be slippery and structurally unsound.
If it is safe to do so from the ground, document the damage with clear photos for your insurance company. Then, contact a qualified roofer to make temporary repairs, like tarping the affected area, to prevent further water entry until permanent restoration can begin.
The Professional Restoration Process
Local water damage pros start by locating the exact entry point and assessing the full extent of the moisture spread. They use moisture meters and thermal imaging cameras to find water you cannot see inside walls and ceilings. This detailed inspection informs the drying plan.
The pros then set up industrial air movers and dehumidifiers to dry the affected structural materials completely. Once the area is dry, they can advise on necessary repairs, which may involve a roofer replacing flashing or a specialist resealing the skylight. Policies vary, and your insurer decides what is covered.
- Comprehensive moisture mapping of the affected area
- Strategic placement of drying equipment
- Monitoring of drying progress daily
- Removal of unsalvageable, soaked materials
- Sanitization of affected surfaces to inhibit mold
- Coordination with roofing contractors for permanent repair

Can a small leak around a skylight cause major damage?
Yes, even a small, persistent leak can cause significant damage over time. Water slowly rots wooden roof decking and framing, compromises insulation, and creates a perfect environment for mold growth inside your walls and attic, leading to costly repairs.
Who should I call first, a roofer or a water damage pro?
For active leaking, a roofer can make a temporary exterior repair, like installing a tarp, to stop more water from entering. Then, contact local water damage pros to handle the interior water extraction, drying, and mitigation of mold risk from the moisture already inside.
Will my homeowner's insurance cover this type of damage?
Most standard policies cover sudden, accidental damage from wind or hail. However, they may not cover damage from lack of maintenance or wear and tear. Policies vary, and your insurer decides what is covered. Document the damage thoroughly and file a claim promptly.
