The short answer

What Temporary Roof Tarping Involves

Temporary roof tarping is a short-term fix after a storm, fallen branch, or other event damages your roof. A large, reinforced tarp is secured over the damaged area to block rain and debris. The tarp is usually anchored to the roof edges or fastened with straps and weighted objects, depending on the roof's shape and the damage's size.

The goal is to keep water out until a permanent roof repair or replacement can happen. Tarps are not a long-term solution, but they can buy you time. The pros who install them will assess the damage and choose a tarp size and anchoring method that fits your roof. If you live in Sammamish, you may need tarping after a heavy storm, but the process is the same anywhere.

How Long a Tarp Lasts

A well-installed temporary tarp can last from a few weeks to a few months. The lifespan depends on the tarp material, how securely it is attached, and the weather it faces. Heavy wind, snow, or intense sun can shorten that time. A tarp that flaps or collects water can rip or come loose faster.

You should plan to replace the tarp if it shows signs of wear, such as tears, loose straps, or water pooling. If the permanent repair is delayed, you may need a second tarp or a more durable temporary cover. The pros can advise on what to expect based on your roof's condition and the local weather patterns, though no one can predict exact timing.

  • Tarp material quality affects durability
  • Installation method determines how well it stays put
  • Wind and rain can loosen or tear the tarp
  • Sun exposure can degrade the tarp over time
  • Roof slope and shape influence how long it lasts
  • If you see water inside, the tarp may need adjustment

When to Call for Tarping

Call for temporary tarping as soon as you notice a roof leak or damage, especially if rain is forecast. Waiting can lead to more water inside, which can damage ceilings, walls, and belongings. Acting quickly helps limit the spread of water damage, but you should still take safety precautions first, like avoiding downed power lines.

If you cannot get a tarp installed right away, use a bucket or tarp inside to catch drips. But do not climb onto a damaged roof yourself; that can be dangerous. The pros have the equipment and training to install a tarp safely. They will also check for other issues, like loose shingles or structural damage, that might affect the tarp's fit.

What Happens After Tarping

After the tarp is in place, you should address the underlying roof damage. The tarp is only a stopgap. You will need a permanent repair or replacement, which may involve a roofer or a general contractor. The tarp can stay on until that work is scheduled, but you should not leave it on indefinitely.

While the tarp is on, check it after storms for any new damage. If you notice water stains on your ceiling or walls, that could mean the tarp has shifted. You may also need to dry out the affected areas inside your home to prevent mold growth. Structural drying and dehumidification can help, but that is a separate service.

Cost and Insurance Considerations

The cost of temporary tarping can vary widely. It often depends on the size of the tarp, the roof's height and slope, and how much damage needs to be covered. Expect to pay more for a steep roof or if the tarp must be custom-cut. The final price also depends on the tarp material and the labor involved.

Your insurance policy may cover temporary tarping as part of a covered claim, but that outcome is not certain. Policies vary, and your insurer decides what is covered. Check your policy and talk to your insurance company about whether tarping is included. You should also document the damage with photos for your claim, but do not assume coverage without reading the details.

Frequently asked questions

Can I put a tarp on my roof myself?

You could try, but it is risky. Climbing on a wet or damaged roof can be dangerous, and a poorly installed tarp may blow off or let water in. The pros have the right equipment and know how to anchor tarps securely. For safety and effectiveness, it is often better to have it done professionally.

How do I know if the tarp needs replacing?

Look for visible tears, loose straps, or areas where the tarp is flapping. If water pools on top of the tarp or you see new water stains inside, the tarp may have failed. Check after heavy rain or wind. If the tarp looks worn or the roof repair is delayed, ask the pros about a replacement.

Will tarping stop all water from coming in?

A properly installed tarp should keep most water out, but it is not a perfect seal. Wind-driven rain can sometimes find a way around edges or through gaps. The tarp is designed to minimize water entry, not ensure it stops every drop. If you still see leaks, the tarp may need adjustment or the damage may be more extensive.
