How Do Contractors Tarp a Roof After Storm Damage?
Last updated October 31, 2026
The short answer
Initial Roof Assessment
Before any tarp goes on, the pros inspect the roof to understand the extent of the damage. They look for missing shingles, punctures, or lifted flashing. This helps them decide how large a tarp is needed and where to anchor it securely. If the roof structure is unstable, they may take extra precautions to stay safe.
The inspection also checks for standing water or trapped moisture. The pros clear away leaves, branches, and other debris that could tear the tarp or trap water. A clean surface allows the tarp to lie flat and seal better. This step is quick but important for a good result.
Choosing the Right Tarp
The pros select a tarp based on the size of the damaged area and the roof's slope. Heavy-duty polyethylene tarps are common because they resist tearing and water. The tarp must be large enough to overlap the damage by at least a few feet on all sides. This extra overlap helps keep water from seeping around the edges.
For steep roofs, the pros may use a tarp with reinforced grommets to handle wind stress. They also consider the local climate. In cold regions, the tarp needs to shed snow and not sag under its weight. A proper fit now means fewer problems later.
- Measure the damaged area and add overlap
- Pick a tarp with reinforced edges
- Check for grommets or tie-down points
- Ensure the tarp is UV-resistant
- Match tarp thickness to storm severity
Securing the Tarp
Once the tarp is laid over the damaged section, the pros fasten it to the roof. They use roofing nails or screws driven into solid wood, such as rafters or decking. The fasteners are placed along the edges and in a grid pattern across the tarp to prevent flapping. This keeps the tarp tight and less likely to tear in high winds.
For extra hold, the pros may add wooden battens over the tarp's edges. These are strips of wood that distribute the fastening pressure and reduce stress on the tarp material. In areas with strong storms, this technique helps the tarp stay put. The goal is a temporary seal that lasts until permanent roof repairs begin.
Sealing Edges and Seams
Water can sneak in through gaps at the tarp's edges or where two tarps overlap. The pros tuck the tarp under existing shingles or flashing where possible. They also use roofing cement or adhesive to seal seams and edges. This creates a watertight barrier that directs rain away from the damaged area.
If the roof has valleys or chimneys, the pros pay extra attention to those spots. They may cut the tarp to fit around protrusions and then seal the cuts with tape or mastic. A careful seal now prevents leaks from turning into bigger water damage inside your home. The pros also check that the tarp does not block gutters or downspouts.
Final Checks and Maintenance
After the tarp is installed, the pros do a final walk-around to make sure everything is tight and smooth. They check for any loose fasteners or wrinkles that could catch wind. They also verify that the tarp slopes slightly so water runs off rather than pooling. This simple step extends the tarp's life and keeps your home dry.
A tarp is a temporary fix, not a permanent one. You should plan to have the roof repaired as soon as possible. In the meantime, check the tarp after heavy storms or strong winds. If you live in a cold climate, keep an eye on the tarp during winter snowmelt. If you notice damage, contact the pros for a re-secure or replacement. Your insurance policy may cover the cost, but that depends on your coverage. Policies vary, and your insurer decides what is covered.

How long does a roof tarp last?
A well-secured tarp can last a few weeks to a few months, depending on weather and tarp quality. Heavy wind, snow, or sun can shorten its life. Check it regularly and after storms. If it tears or loosens, have the pros fix it promptly to avoid water damage.
Can I tarp my own roof?
You can try, but roof work is risky, especially after storm damage. Climbing on a wet or damaged roof can be dangerous. The pros have the right ladders, safety gear, and fastening methods. If you do it yourself, use a sturdy ladder and have someone spot you. But for safety, hiring a pro is often better.
Will my insurance pay for tarping?
Insurance coverage for tarping depends on your policy and the cause of damage. Many policies cover emergency measures to prevent further damage. Check your policy and talk to your insurance company. Policies vary, and your insurer decides what is covered. Keep receipts and photos for your claim.
