How Do Pros Tarp a Damaged Roof After a Storm?
Last updated October 25, 2026
The short answer
Initial Safety and Damage Assessment
Before any work begins, the pros evaluate the roof's structural integrity. They look for hazards like damaged trusses, loose shingles, or hidden punctures. This step determines the safest approach and the size of tarp needed. They also check the attic for signs of active leaks to understand the full scope of the water entry points.
Homeowners should stay clear of the damaged area and never attempt to climb onto a storm-damaged roof themselves. The assessment helps plan the tarp placement to protect the most vulnerable sections of the home. It ensures the temporary covering effectively channels water away from the interior living spaces below.
Choosing and Positioning the Right Tarp
The pros use a thick, reinforced polyethylene or canvas tarp designed for roofing. It must be large enough to cover the damaged section and extend over the roof's ridge by several feet. This over-the-ridge method is crucial as it prevents wind from getting underneath and water from pooling behind the tarp.
Proper positioning stops water from seeping under the covering and into the attic. The tarp is laid out flat and smoothed to avoid wrinkles that could trap water. If the damage is near the edge, the tarp will also extend down the roof slope to direct runoff safely into the gutters or away from the foundation.
Securing the Tarp with Battens and Nails
To secure the tarp, long wooden boards called battens are placed over its edges. These are typically one-by-fours or two-by-fours. The pros then drive roofing nails through the battens and tarp material into the roof decking or sheathing. This method distributes stress and prevents the tarp from tearing at the nail holes.
Nails are placed closely together along the battens to create a tight seal. Additional battens may be run vertically over the tarp's field to weigh it down and combat wind uplift. The fasteners are not driven into shingles alone, as they can pull loose; they seek solid wood beneath for a firm hold.
Sealing Edges and Managing Water Runoff
Special attention is given to sealing the tarp's top edge over the roof ridge. Pros often use a separate batten or cap to ensure no gaps exist. They also tuck or seal the lower edges to direct water flow. The setup is designed to handle heavy rain, mimicking the water-shedding function of the original roof.
Managing runoff prevents new water damage to siding or the home's foundation. The pros may create temporary channels if gutters are damaged. The goal is to keep all water on the outside of the tarp and away from the interior. A properly installed tarp should not leak or billow in the wind.
- Tarps are anchored over the roof ridge, not just on a slope.
- Wooden battens are nailed into solid roof decking, not just shingles.
- Seams or overlaps in the tarp are sealed with waterproof tape.
- Extra battens are placed across the tarp's center to resist wind.
- Lower edges are secured but allow for proper drainage.
- The work area is cleared of debris to ensure a flat seal.
Next Steps After Temporary Protection
Once the roof is tarped, it is a temporary fix. The pros will advise you on the next steps for permanent repair. This often involves consulting with a roofing contractor. Meanwhile, monitor the covered area and the attic for any signs of new moisture, as severe weather can compromise even a well-installed tarp.
You should also contact your insurance company to report the storm damage. Document the damage with photos before and after the tarp is installed. Policies vary, and your insurer decides what is covered. The tarp helps mitigate further loss, which is often a requirement for insurance claims. Schedule a permanent roof repair as soon as possible.

Can I tarp my own roof to save money?
Climbing on a storm-damaged roof is extremely dangerous due to unstable surfaces and hidden structural damage. Professionals have the correct safety equipment, materials, and technique to create an effective, temporary seal that prevents further interior water damage.
How long will a roof tarp last?
A professionally installed tarp is a short-term solution, typically intended to last for several weeks to a few months. It can withstand rain and wind, but it is not a permanent repair. You should arrange for a complete roof repair at the earliest opportunity.
What if water is still getting inside after tarping?
If water intrusion continues, the tarp may have been dislodged, or the leak's source might be elsewhere, like in siding or windows. Contact the pros to re-inspect the installation. Also, check your attic for other potential entry points that the tarp does not cover.
