Post-Storm Roof Inspection Checklist for Washington Homes (Step-by-Step + Photos)

Washington storms can strike with little warning — heavy rain, high winds, hail, and falling debris can all cause roof damage that isn't immediately visible from the ground. Catching storm damage early is critical to preventing water infiltration, mold growth, and structural deterioration.

This step-by-step checklist guides you through a thorough post-storm roof inspection that any Washington homeowner can follow.

Safety First

Never climb onto a wet or damaged roof. Post-storm inspections should begin from the ground and interior. If you suspect structural damage, contact a licensed Washington roofing contractor for a professional inspection immediately.

Step 1: Interior Inspection (15 Minutes)

Start inside your home, working from the top floor down:

• Check ceilings for water stains, discoloration, or bubbling paint — these indicate active leaks
• Inspect attic spaces with a flashlight for daylight showing through roof boards, wet insulation, or water trails on rafters
• Look for mold or musty smells that weren't present before the storm
• Check around skylights, chimneys, and vents — these are the most common leak points
• Open and close windows and doors near the roofline — if they suddenly stick, the roof structure may have shifted

Step 2: Ground-Level Exterior Inspection (20 Minutes)

Walk the perimeter of your home and document everything with photos:

• Look for shingles or roofing material on the ground — any displaced material indicates roof damage
• Check gutters and downspouts for granule buildup (indicates shingle damage), blockages, or detachment
• Inspect siding near the roofline for impact marks from hail or debris
• Look for downed branches or debris on or near the roof
• Check the chimney for visible damage, cracked mortar, or leaning
• Examine fascia and soffit boards for water damage, sagging, or separation

Step 3: Binocular Roof Survey (10 Minutes)

Using binoculars from the ground:

• Scan for missing, cracked, or curled shingles — compare to pre-storm photos if available
• Look for lifted flashing around chimneys, vents, skylights, and valleys
• Check ridge caps (the shingles along the peak) — these are especially vulnerable to wind damage
• Look for sagging sections that could indicate structural damage or water pooling
• Note any exposed underlayment or bare wood — this requires immediate professional attention

Step 4: Document Everything

For insurance claims, thorough documentation is essential:

• Take dated photos and videos of all damage from multiple angles
• Note the date and type of storm (wind speed, hail size, duration)
• Keep a written log of when you discovered each issue
• Save any fallen shingles or debris as physical evidence
• Contact your insurance company within 24–48 hours of discovering damage

Step 5: When to Call a Professional

Contact a licensed Washington roofing contractor if you observe:

• Any missing shingles or exposed underlayment
• Active leaks or water stains inside your home
• Sagging or structural deformation of the roof deck
• Significant granule loss in gutters (indicates shingle deterioration)
• Hail impact marks on shingles, vents, or flashing
• Any damage you cannot safely assess from the ground

Common Storm Damage Types in Washington

Western WA (Seattle, Tacoma, Olympia):

• Wind-lifted shingles and ridge caps from Puget Sound storms
• Branch and debris impact from wind-toppled trees
• Persistent moisture infiltration at flashing points
• Gutter overflows leading to fascia and soffit damage

Eastern WA (Spokane, Yakima, Wenatchee):

• Hail impact damage to shingles and metal panels
• Snow load stress causing sagging or collapse
• Ice dam formation at eaves
• Thermal shock cracking after rapid temperature changes

Post-Storm Maintenance Tips

After addressing immediate damage:

1. Clear all debris from the roof surface, valleys, and gutters
2. Trim overhanging branches that could cause future damage
3. Schedule a professional inspection within 2 weeks — some damage is only visible up close
4. Review your insurance policy to understand deductibles and coverage limits before filing
5. Keep records of all repairs and inspections for future reference

Regular post-storm inspections are one of the most cost-effective ways to extend your roof's lifespan in Washington's demanding climate. A small crack or lifted shingle caught early can save thousands in water damage repairs down the road.
