The short answer
Assess the Damage First
Before you climb anywhere, look at the roof from the ground. Check for loose shingles, sagging areas, or holes. If you see exposed rafters or the decking looks weak, do not step on it. Wind damage can make the structure unstable.
Also check inside your home. Look for water stains on ceilings or walls, and place buckets under active leaks. This tells you where the tarp needs to cover. If the damage is widespread, a professional should handle it.
Gather the Right Materials
You need a tarp large enough to cover the damaged area plus extra on all sides. Polyethylene tarps with reinforced edges work well. You also need lumber, such as 2x4s, to sandwich the tarp edges, and roofing nails or screws to secure it.
Have a hammer, utility knife, and work gloves ready. A ladder with a spotter is essential. If the roof is more than one story, consider hiring the pros. They have the equipment to work safely at height.
- Heavy-duty tarp, at least 6 mil thick
- 2x4 lumber cut to fit the tarp edges
- Roofing nails or exterior screws
- Hammer and utility knife
- Work gloves and safety glasses
- Ladder with a second person to hold it
Secure the Tarp Properly
Lay the tarp flat over the damaged area, with the damaged part centered. Fold the edges over the lumber and nail the lumber to the roof decking. Space nails every 6 to 8 inches. Do not nail into gaps or holes.
Use extra lumber on the high side of the tarp to prevent wind from lifting it. Overlap the tarp at least 2 feet past the damage. If the roof has a ridge, drape the tarp over it and secure both sides.
Work in Safe Conditions
Only tarp the roof when it is dry and the wind is calm. Wet or icy surfaces are slippery, and strong wind can catch the tarp and pull you off balance. Do not work during a storm, lightning, or if the roof is still being hit by wind.
If you feel unsteady or the roof is too steep, stop. Your safety matters more than a temporary fix. A fall can cause serious injury. See a doctor if you feel unwell after any fall.
When to Call the Pros
Large holes, sagging roof decks, or damage that affects the structure need professional attention. The pros can tarp large areas safely. They also know how to manage water that has already entered your home.
The cost to tarp a roof depends on the size of the damage, the roof's pitch, and the materials needed. Typically, it ranges from a few hundred to over a thousand dollars, but the final price depends on the specific situation. Your insurance company may help with costs, but policies vary, and your insurer decides what is covered.
- Damage larger than a few square feet
- Roof decking is soft or sagging
- You cannot reach the area safely
- Water is actively leaking inside
- You need help moving furniture or protecting belongings

Can I tarp my roof by myself?
Yes, if the damage is small and the roof is safe to walk on. Use a sturdy ladder, have someone hold it, and only work in dry, calm conditions. For anything large or steep, call local water damage pros.
How long can a tarp stay on a roof?
A tarp is a temporary fix, usually lasting a few weeks to a few months. Sun and wind wear it down. Check it after storms and re-secure any loose edges. Plan for permanent repairs as soon as possible.
What if water has already damaged my ceiling?
Remove wet drywall and insulation to prevent mold. Place buckets under leaks and move furniture away. The pros can handle drying and cleanup. If you live in Mesa, keep your shutoff valve location written down for future emergencies.
