The short answer

How Water Enters After a Storm

Storm winds can lift shingles, break tiles, or tear off entire sections of roofing. Hail can puncture roofing materials or crack vents and skylights. Once the roof's outer layer is compromised, heavy rain can pour directly into your attic and living spaces. This initial water intrusion causes immediate damage to insulation, drywall, and personal belongings.

Even a small opening can allow a surprising amount of water to enter your home. It is crucial to stop this water flow as soon as it is safe to do so. Emergency tarping is the standard first step to protect the structure.

The Goal of a Temporary Tarp

The primary goal is to create a watertight seal over the hole or damaged section. This is not a cosmetic repair, but a critical barrier against further rain. A properly installed tarp directs water off the roof and into the gutters, just like the original roofing should. It protects the interior from additional soaking while you arrange for a permanent fix.

This temporary measure buys you time. It helps prevent secondary damage like mold growth, which can begin within 24 to 48 hours of water exposure. By keeping the area dry, you also make the eventual roof repair simpler and often less costly. The tarp is a shield, allowing the interior drying process to proceed if water already got in.

  • Waterproof, heavy-duty polyethylene or canvas tarps are used.
  • The tarp must extend several feet beyond the damaged area in all directions.
  • Wooden strips called battens are placed over the tarp's edges.
  • Long roofing nails or screws with plastic washers fasten the battens to the roof deck.
  • All seams and edges are sealed with a special waterproof tape or mastic.
  • The tarp is pulled taut to prevent wind from getting underneath it.

Safety Comes Before Any Action

Never attempt to tarp a roof during active rain, lightning, or high winds. Wait for the storm to pass completely. The roof surface will be wet and extremely slippery, and hidden structural damage can make it unsafe to walk on. If you have any doubt about your ability to do this safely, do not go onto the roof yourself.

Your safety is more important than the building. If you must assess damage from the ground, use binoculars. Only use a sturdy, properly secured ladder if you need to look more closely, and have someone hold the base. Many homeowners wisely choose to leave this dangerous work to the pros who have specialized fall-protection gear and experience.

When to Call for Professional Help

Consider calling local water damage pros for tarping if the damage is extensive, the roof is steep, or you are uncomfortable with heights. They have the equipment and training to secure a tarp effectively in difficult conditions. A poorly secured tarp can fail, causing more damage, or can itself become a dangerous projectile in the next gust of wind.

The pros can also assess the full scope of the water damage inside your home. They can check for hidden moisture in walls and ceilings that needs to be dried. This integrated approach, securing the roof and addressing the interior water, is the most effective way to minimize long-term problems. They can also coordinate the next step with a qualified roofing contractor.

What Happens After the Tarp Is Up

The tarp is a temporary solution, typically lasting for several weeks at most. Your next immediate call should be to a qualified roofing contractor to schedule a permanent repair. Do not delay this, as sun and wind will degrade the tarp material over time.

Document everything for a potential insurance claim. Take clear photos of the storm damage before the tarp is installed, and again after it is secured. Keep all receipts for materials or services related to the tarping and any initial water mitigation. Policies vary, and your insurer decides what is covered. A detailed record supports your claim.

Frequently asked questions

Can I use a regular plastic sheet from the hardware store?

Heavy-duty, woven tarps designed for roofing are far more effective. Lightweight plastic sheeting tears easily on roof nails and cannot withstand wind. It often requires more fasteners, which can create new holes in your undamaged roof. Using the right material provides a more reliable temporary seal.

Will my homeowners insurance cover tarping?

Many policies cover the cost of emergency measures taken to prevent further damage after a covered peril, like a storm. This often includes tarping. You must document the damage first. Policies vary, and your insurer decides what is covered. Always check your policy and contact your agent to report the damage.

How long can a roof stay tarped?

A professionally installed tarp can protect a roof for several weeks, but it is not a permanent fix. UV radiation from the sun and temperature changes will weaken the material. Wind can loosen fasteners. Schedule a permanent roof repair as soon as possible to avoid a failure of the temporary cover.
