When a roof leak strikes during a Washington rainstorm, fast action prevents thousands in water damage. Learn when to tarp it yourself and when to call a pro.
A roof leak during a Washington rainstorm is a homeowner's worst nightmare. Water flowing into your attic, walls, and living spaces can cause thousands of dollars in damage within hours. Knowing how to respond quickly — and safely — can save your home and your wallet.
When to DIY vs. Call a Professional
You can safely tarp if:
- The roof has a moderate pitch (less than 6/12)
- The weather has calmed enough for safe access
- The damage is localized and accessible
- You have a helper and proper equipment
Call a professional immediately if:
- The roof is steeply pitched or has multiple levels
- There is structural damage or sagging
- Lightning, high winds, or heavy rain are ongoing
- You cannot safely reach the damaged area
- There are downed power lines near the roof
Materials Needed
- Heavy-duty polyethylene tarp (at least 6 mil thickness, blue tarps work)
- 2x4 lumber boards (at least 8 feet long)
- Roofing nails or screws
- Hammer or screw gun
- Safety harness and roof anchors
- Non-slip footwear
- Ladder rated for your weight plus materials
- A helper on the ground
Step-by-Step Tarping Guide
Step 1: Control Interior Damage
Before going on the roof:
- Place buckets under active leaks
- Move furniture and valuables away from water
- Photograph all damage for insurance documentation
Step 2: Assess from the Ground
Walk around the house and look for obvious damage points — missing shingles, fallen branches, or visible holes. Plan your approach before climbing.
Step 3: Set Up Safely
- Position ladder on firm, level ground
- Have your helper hold the ladder base
- If using a safety harness, anchor it to a structural member before stepping onto the roof
- Never work on a wet roof without proper footwear
Step 4: Position the Tarp
- Unroll the tarp so it extends at least 4 feet past the damaged area on all sides
- Extend the tarp over the ridge (peak) if possible — this prevents wind from lifting it
- Ensure the tarp lies flat without bunching
Step 5: Secure the Tarp
- Lay 2x4 boards along the tarp edges
- Nail or screw through the boards and tarp into the roof sheathing
- Space fasteners every 12–18 inches along each board
- Wrap excess tarp around a final 2x4 and nail it down to create a weighted edge
Step 6: Verify the Seal
- Check that water will flow off the tarp, not pool on it
- Ensure all edges are secured — wind can lift unsecured sections easily
- Verify from inside the attic that the tarp covers the leak source
Common Tarping Mistakes
- Tarp too small — Always use a tarp significantly larger than the damaged area
- Not extending over the ridge — Wind easily lifts tarps that don't cross the ridge
- Using staples — Staples pull out in wind; use nails through 2x4s
- Tarping in active storms — Wait for a break in severe weather
- Not addressing interior damage — Tarp the roof AND manage water inside
After Tarping: Next Steps
- Call your insurance company within 24 hours and report the damage
- Contact a licensed WA roofing contractor for a permanent repair estimate
- Document the tarping with photos and receipts — insurance may cover reasonable emergency measures
- Monitor the tarp after every rainfall event until permanent repairs are made
- Don't remove the tarp yourself — let your contractor remove it as part of the repair
