The short answer

How Heat Affects Your Home

Extreme heat from a summer storm can stress your roof and siding. Prolonged sun exposure can dry out sealants and caulk, causing them to crack and let water in later. Heat can also warp wooden trim or vinyl siding, creating gaps where moisture sneaks through.

You can check for cracked or brittle seals around windows, doors, and roof penetrations like vents or chimneys. If you spot damage, note it and keep the area dry until a pro can assess it. Acting quickly after a storm helps prevent small heat-related gaps from becoming bigger water problems.

Hail Damage and Water Entry

Hail can dent metal roofs, crack asphalt shingles, and break skylights or windows. Even small dents can weaken the surface, and cracks let rainwater in during the next downpour. You may not see the damage from the ground, but water can find its way through tiny openings.

After a hailstorm, look for fallen leaves or debris in gutters and downspouts, which can block drainage and cause overflow. Check attic spaces for wet spots or stains, and take photos of any visible damage. Local water damage pros can help you understand what needs attention, but a roofer or window professional may be needed for repairs.

  • Dents on metal roofs or gutters
  • Cracked or missing shingles
  • Broken or cracked skylights and windows
  • Wet attic insulation or ceiling stains
  • Clogged gutters from hail and debris

Wind Damage and Leaks

Strong winds can lift shingles, tear flashing, and push rain sideways under siding. A loose or missing shingle exposes the underlayment, and wind-driven rain can soak walls and ceilings. Trees or branches can also fall on roofs, causing immediate structural damage and water entry.

After the storm passes, walk around your yard and look for fallen branches or debris near your roofline. Check for lifted or missing shingles and any visible holes. If you see water stains on ceilings or walls, act quickly to move belongings and contain the spread. The pros can dry the area and locate the source, but you may also need a roofer or tree service for the initial cause.

  • Lifted or missing roof shingles
  • Torn or displaced flashing around chimneys and vents
  • Branches or trees leaning on the roof
  • Wind-driven rain stains on exterior walls
  • Water spots on ceilings or walls inside

What to Do Right After the Storm

Your first priority is safety. Stay away from downed power lines and do not walk on a wet or damaged roof. If you smell gas or see sparks, leave the house and call for help. For water that has entered your home, you can move furniture to a dry area and place buckets under active drips.

Document the damage with photos and notes for your insurance records. If you live in Sammamish, keep your shutoff valve location written down so you can stop water quickly if a pipe breaks. Then call local water damage pros to assess the situation and begin drying. They can help determine what is salvageable and what needs replacing, but the repair work may involve other trades.

  • Turn off power in affected rooms if safe
  • Move rugs and furniture off wet carpet
  • Use towels or a wet vacuum to remove standing water
  • Open windows for ventilation if humidity is high
  • Take photos of all damage before cleanup

When to Call the Pros

You can handle small spills and surface drying, but significant water damage from heat, hail, or wind often needs professional help. Water can soak into drywall, wood, and insulation, and it may hide behind walls or under floors. The pros use drying equipment and moisture meters to find hidden wet spots and prevent mold growth.

If you notice a musty smell, warped floors, or bubbling paint, call the pros soon. They can also coordinate with other professionals like electricians or roofers if needed. Policies vary, and your insurer decides what is covered. If you have questions about your policy, check it directly with your insurance company.

Frequently asked questions

Can I dry out my attic myself after a hail storm?

You can set up fans and dehumidifiers to help dry visible wet spots. But if water soaked into insulation or drywall, you may need professional drying equipment to reach hidden areas. See a doctor if you feel unwell from mold exposure, and call the pros if the smell persists.

How do I know if wind damage caused a leak?

Look for water stains on ceilings or walls, especially near rooflines or windows. Check attic spaces after a rain for fresh drips. If you see lifted shingles or torn flashing, wind likely caused the leak. A pro can confirm by testing with water and inspecting from the roof.

What should I document for my insurance claim?

Take clear photos of all damage, including the exterior and any interior water stains. Note the date and time of the storm, and keep receipts for any emergency supplies like buckets or fans. Check your policy for specific requirements, and contact your insurance company directly for guidance.
