The short answer

Safety First

Before you climb up, check the ground for downed power lines and wait until the storm has fully passed. If the roof is wet, steep, or has loose shingles, do not attempt any work. A fall from a roof can cause serious injury, and the pros have the right gear and training for such conditions.

Also, clear the area below where you will be working. Move patio furniture, potted plants, and other items that could be damaged by falling debris or water. Wear rubber-soled shoes with good grip, and have someone inside the home to hand you tools or call for help if needed.

Gather Materials

For a temporary patch, you will need a heavy-duty tarp (at least 6 mil thick), roofing nails, a hammer or nail gun, a utility knife, and some wood furring strips or 2x4s. The tarp should be large enough to overlap the damaged area by at least two feet on every side.

You also need a ladder that is tall enough to reach the roof safely, and a dry day or at least a break in the rain. If you have any doubts about your ability, or if the roof is high or steep, stop and wait for the pros.

  • Heavy-duty tarp, 6 mil or thicker
  • Roofing nails with large heads
  • Hammer or nail gun
  • Furring strips or 2x4s for extra hold
  • Utility knife to cut the tarp
  • Ladder with secure footing

Secure the Tarp

Lay the tarp flat over the damaged area, making sure it covers the hole completely and extends beyond it on all sides. The smooth side goes down to avoid catching wind. Hold the tarp in place with a few roofing nails, starting in one corner and working across to the opposite side.

Then, place a furring strip or 2x4 along the top edge of the tarp and nail through it into the roof. This prevents the tarp from being pulled up by the wind. Do the same along the bottom and sides, keeping the nails close enough together so the tarp cannot flap.

  • Overlap the damage by at least 2 feet
  • Smooth side down to reduce wind lift
  • Nail through a wood strip to spread the hold
  • Space nails about every 6 inches
  • Check for any gaps or loose edges
  • Trim excess tarp with a utility knife

When to Call the Pros

This temporary patch is only a stopgap. A tarp can fail in high winds or heavy rain, and it does not address structural damage. The pros can assess the roof, remove the damaged shingles, and install a durable repair that lasts.

If you notice water stains inside your home, sagging ceilings, or attic mold, you need professional help. Water damage can spread quickly, so act fast to call local water damage pros. Even if the tarp holds, have the roof inspected as soon as possible. Policies vary, and your insurer decides what is covered.

After the Patch

Once the tarp is in place, check it regularly, especially after another storm. Look for loose nails, lifted edges, or pooling water. If the tarp tears or comes loose, re-secure it or add another layer. Keep it in place until a professional can make permanent repairs.

Inside your home, watch for new leaks or water marks on your ceiling. Move belongings away from the area and place buckets or containers under any drips. For help with interior damage, consider the roof leak water damage cleanup service. Document all damage for your insurance record, and review your policy.

  • Inspect the tarp after heavy rain or wind
  • Re-nail any loose edges
  • Watch for new leaks inside your home
  • Move furniture away from the affected ceiling
  • Photograph the damage for your records

Frequently asked questions

How long can a tarp stay on a roof?

A tarp can last for a few weeks, but it is not a permanent solution. It may shift or tear in severe weather. The pros can install a more secure temporary cover, or you can plan to have the roof repaired soon. The longer it stays, the higher the risk of water intrusion.

What if the tarp leaks anyway?

If the tarp leaks, water may be getting in through a different spot, or the tarp may not be overlapping the damage enough. Re-position the tarp to cover a larger area, and add extra nails. If leaks inside your home continue, you may need professional water cleanup to prevent mold.

Can I use silicone or roof cement for a temporary patch?

Roof cement or a patch kit can work for small holes, but they may not hold on a wet or dirty surface. A tarp is a more reliable temporary fix. For cracks or small punctures, apply roof cement generously and press a piece of shingle or felt into the wet compound. Let it dry.
