How Do I Tarp a Leaking Roof During a Storm?

Last updated October 28, 2026

The short answer

Safety First

Before you think about climbing onto your roof, check the weather. High winds, heavy rain, or lightning make roof work dangerous. If the storm is severe, wait until it passes. Your safety matters more than a little extra water inside.

If you do go up, wear shoes with good grip and use a sturdy ladder. Have someone hold the ladder or spot you. Never work alone on a wet roof. If the roof is steep or you feel unsteady, stop and call the pros.

  • Wait for winds under 20 mph
  • Use a harness if you have one
  • Avoid power lines and tree branches
  • Keep a phone with you for emergencies
  • Have a spotter on the ground

Find the Leak

First, locate the leak inside your home. Check the ceiling or attic for water stains, drips, or damp spots. This tells you the general area of the roof problem. Then, from the outside, look for missing shingles, cracks, or holes around that spot.

If you cannot see the damage from the ground, use binoculars. Mark the area with chalk or a small flag so you can find it when you get on the roof. Do not walk on the roof to search if it is wet or slippery.

Get the Right Tarp

Use a heavy-duty polyethylene tarp, at least 6 mil thick. Make sure it is large enough to cover the damaged area plus extra on all sides. A 10x12 foot tarp usually works for a small leak. For larger damage, use a bigger tarp or overlap two.

You also need nails or screws with washers, a hammer or drill, and a utility knife. Some people use rope or bungee cords to tie the tarp down. Keep all supplies ready before you climb up.

Secure the Tarp

Lay the tarp over the damaged area, starting from the lower edge and working up. This way, water runs over the tarp, not under it. Smooth out wrinkles so water does not pool. Leave at least 2 feet of tarp on each side of the leak.

Fasten the tarp with roofing nails or screws with washers, placed every 12 to 18 inches along the edges. Do not nail through the middle; that can create new holes. For extra hold, run a rope over the tarp and tie it to a chimney or heavy object.

  • Nail along the edges, not the middle
  • Overlap tarps from lower to upper
  • Use washers to prevent tearing
  • Tie rope to a sturdy anchor
  • Check the tarp after the storm

When to Call the Pros

A tarp is only a temporary fix. Even if you stop the active leak, water may have already soaked into wood, insulation, or drywall. That can lead to mold and rot. The pros can inspect the roof and the interior damage properly.

They have the right equipment and training to handle steep roofs, large holes, or ongoing storms. They also know how to dry out your home and prevent further damage. If the leak is big or you cannot tarp safely, call for help right away.

Frequently asked questions

Can I tarp my roof during heavy rain?

Tarping in heavy rain is risky because the roof is slippery and you cannot see well. Wait for a break in the storm if possible. If water is pouring in, focus on containing it inside with buckets and towels. Call the pros if the leak is severe.

How long can a tarp stay on my roof?

A tarp is temporary, meant to last a few days or weeks, not months. Sun and wind will weaken it. Check it after each storm and replace it if it tears or comes loose. Schedule a proper roof repair as soon as you can.

What if my roof is too steep to tarp safely?

Do not attempt it. Steep roofs are dangerous even in good weather. Instead, try to slow the leak from inside by placing buckets and moving furniture. Then call a professional roofer or water damage service to handle the tarping and repairs.
