The short answer

How Roof Tarping Works

The process involves covering the damaged area with a specialized, reinforced polyethylene tarp. The pros secure it using wooden boards, called nailers or battens, which are fastened to the roof's solid decking around the perimeter of the hole. This creates a tight seal, preventing wind from getting underneath and water from seeping in. It is a critical stopgap to protect the interior of your home from the elements.

While it looks straightforward, proper roof tarping requires skill and safety equipment. The pros assess the roof's stability and choose secure attachment points that won't cause further damage. An improperly installed tarp can fail during high winds or allow water to pool, leading to more problems. This temporary fix is not a substitute for a professional roof repair by a qualified roofer.

Signs You Need Emergency Tarping

After a storm, inspect your home from the ground for obvious damage. Look for missing shingles, visible holes, or large sections where the roof decking is exposed. Inside your home, check the attic and ceilings for active dripping, water stains, or sagging drywall. Any of these signs indicate your roof barrier is compromised and immediate action is required to prevent interior water damage.

If you see daylight through your roof boards from inside the attic, that is a clear emergency. Fallen tree limbs or debris that have punctured the roof also demand urgent tarping. Even smaller, less obvious damage can let in significant water over time. The goal is to act before the next rainfall, which can follow soon after a storm.

  • Missing, cracked, or lifted shingles.
  • A visible hole or puncture in the roof surface.
  • Exposed wooden roof decking or underlayment.
  • Broken or damaged roof vents, flashing, or skylights.
  • Sagging or bowed sections of the roof line.
  • Water actively dripping into your attic or living space.

The Role of Water Damage Restoration

Roof tarping stops new water from entering, but it does not address water that has already soaked into your home. Water from a roof leak can travel far from the entry point, damaging insulation, drywall, flooring, and personal belongings. This hidden moisture creates an ideal environment for mold growth, which can begin in as little as 24 to 48 hours under the right conditions.

This is where water damage restoration comes in. After the roof is temporarily secured, local water damage pros can inspect the full extent of the water intrusion. They use moisture meters and thermal imaging to find hidden dampness. The drying process involves industrial air movers and dehumidifiers to remove moisture from the structure and air, preventing secondary damage and mold.

Insurance and Temporary Repairs

If you have homeowners insurance, taking reasonable steps to prevent further damage is often a policy requirement. Document the initial storm damage with photos and videos before any temporary repairs are made. Keep all receipts for materials or services related to the emergency tarping, as these mitigation costs may be part of your overall claim. Policies vary, and your insurer decides what is covered.

It is important to communicate with your insurance adjuster. They will need to inspect the damage, so avoid making permanent repairs until that happens. The emergency tarp is considered a temporary protective measure, not a repair. Your insurer will typically outline the claim process and what documentation they require for reimbursement of reasonable mitigation expenses.

Next Steps After Tarping

With the roof temporarily sealed, your next step is to contact a qualified roofing contractor for a permanent repair estimate. A roofer can assess the full damage and provide a plan for a proper, long-term fix. Simultaneously, if water entered your home, contact local water damage pros for a thorough inspection and drying process. These two trades often work in sequence to fully restore your home.

Do not delay permanent repairs. A tarp is designed for short-term weather resistance, not long-term durability. Sun, wind, and temperature changes can degrade the material and its seals over weeks or months. Addressing both the roof repair and any interior water damage promptly is the best way to restore your home's safety, integrity, and value after a storm.

Water damage does not wait

Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Frequently asked questions

Can I tarp my own roof after a storm?

It is not recommended for most homeowners. Working on a storm-damaged roof is extremely hazardous due to unstable surfaces, height, and weather. Improper installation can cause more damage or injury. For safety and effectiveness, this emergency task is best left to trained professionals with the proper equipment and experience.

How long can a roof tarp stay on?

A professionally installed tarp is a temporary solution, typically intended to last for several weeks. It is not a permanent repair. You should arrange for a permanent roof fix as soon as possible, as prolonged exposure to sun and weather will eventually compromise the tarp's waterproof seal.

What if water damage is already inside my home?

If water has entered, you need a water damage inspection immediately. The pros can assess the moisture in walls, ceilings, and insulation. They use industrial drying equipment to prevent mold and structural decay. This restoration work is separate from the roof repair but is equally critical for your home's health.
