Emergency roof tarping: how to do it, who to call, what it costs

Why does a roof tarp matter for your insurance claim?

A tarp does two jobs. It keeps rain out of the house, and it shows your insurer that you did your part. The standard HO-3 homeowners form lists your duties after a loss. One of them is to protect the property from further damage, make reasonable and necessary repairs to protect it, and keep an accurate record of repair expenses. The same form has a “Reasonable Repairs” coverage that pays the reasonable cost of necessary measures taken solely to protect covered property from further damage. It does not raise your policy limit, and it does not excuse you from the other duties. Your policy may be worded differently, so read yours.

Triple-I says not to wait for the adjuster before making temporary repairs, because most policies require these steps and most insurers reimburse reasonable and necessary repairs up to a set dollar amount. The NAIC says the same: cover roof holes and board up windows after you document the damage, and keep every receipt. The Florida Department of Financial Services gives a plain example: plywood, a tarp and duct tape to stop rain coming through a hole left by a tree limb.

The rule is called the duty to mitigate. Our guide to the duty to mitigate after a loss explains how insurers apply it. The short version: photograph first, cover second, save receipts always.

When is it safe to tarp a roof yourself?

Roofs hurt people after storms. Before you climb, check three things.

The weather. GAF, a roofing manufacturer, says never to tarp a roof while it is raining or when the sky is not clear. Wet shingles are slick, and a tarp in the wind is a sail. Wait for dry weather and daylight.

The roof. CDC says not to go inside a home with obvious damage, like downed trees or cracks in the walls or foundation, until a professional inspects it. Treat the roof the same way. If decking is broken, the roof sags, or a tree is still on it, stay off. A low, dry, single-story shingle roof with a small hole is the only reasonable DIY case, and GAF says tarping is a job for at least two people.

The power lines. ESFI says to assume every downed line is live, because the ground around it can be energized up to 35 feet away. OSHA says to avoid using a metal ladder near power lines or exposed electrical equipment.

The ladder rules from OSHA are short. Inspect it first. Set the base one quarter of the ladder’s working length from the wall. Extend it at least 3 feet above the roof edge. Keep three points of contact as you climb, and do not use the top rung. If any of this is not possible, hire a pro. The first 48 hours after a storm are covered on our storm emergency page.

How do you install a roof tarp?

The steps below combine GAF’s guidance with This Old House’s method. Both agree on the main point: boards hold the tarp down, not nails through the plastic.

1. Measure the damage. GAF says the tarp should extend at least 4 to 5 feet past the damaged area on every side. Buy a heavy-duty tarp that big.
2. Cover any hole in the decking first. This Old House recommends 5/8-inch exterior plywood screwed over the opening with 2-inch deck screws, so the tarp has something solid under it.
3. Run the tarp over the ridge. Unroll it so one edge goes over the peak and a few feet down the other side. This Old House says this keeps water from running under the tarp.
4. Anchor the edges with boards. Wrap the lower edge of the tarp twice around a 1x3 strip, then screw the strip into the sheathing with screws no more than 10 inches apart (This Old House). GAF says to run the boards perpendicular to the ridge so water does not pile up against them.
5. Pull it tight. Lay the tarp flat against the roof, then board the remaining edges the same way.
6. Do not nail the open tarp. GAF says nailing it directly to the shingles without boards leads to ripping and often will not hold.

Tile is different. This Old House says screws cannot go into tile, so the tarp is fastened at the rakes and eaves instead. That is a roofer’s job.

DIY, a contractor, or Operation Blue Roof?

The right answer depends on how much time you have. A cover installed today by you or a roofer stops water now. Blue Roof crews come only after sign-up and a damage assessment, and the program is not activated for every storm. FEMA has said residents who use a self-help tarp in the meantime may still be eligible for Blue Roof.

What is Operation Blue Roof and how do you sign up?

Operation Blue Roof is run by the U.S. Army Corps of Engineers for FEMA. Crews install fiber-reinforced plastic sheeting over damaged roofs so people can stay in their homes until permanent repairs are arranged. The Corps says it is a free service with no costs to the homeowner. It starts only after FEMA assigns the mission to the Corps at the request of the affected state, so it is not available after every storm. As of October 2026 the Corps lists no active Blue Roof mission.

To qualify, the Corps says the home must be your primary residence, no more than 50 percent of the roof framing can be damaged, and the framing must be able to support the sheeting. The roof must be standard shingles or a similar material that crews can nail into. Metal roofs and mobile homes are decided case by case. Slate, asbestos and clay tile roofs are not covered. Renters qualify if they have legal permission to keep living in the home, but the owner must sign the Right of Entry form.

Sign-up runs through blueroof.gov when a mission is active. The Right of Entry form lets Corps staff assess the damage and lets contracted crews work on the roof. The Corps asks you to remove debris from the roof and secure pets before crews arrive. If anyone asks you to pay for a Blue Roof, the Corps says to call the FEMA Disaster Fraud Hotline at 1-866-720-5721.

What does roof tarping cost?

HomeAdvisor’s June 2026 figures put professional roof tarping between $150 and $3,300, with a national average of $450. Materials run about $0.10 to $0.30 per square foot and labor about $0.60 to $2.50 per square foot. Emergency or after-hours service often costs 1.5 to 2 times the standard rate. A tarp, HomeAdvisor says, lasts about 90 days before it degrades.

Price depends on roof height and pitch, the size of the opening, the roofing material, and how many other roofs in town need the same work that week. Our roof tarping and board-up cost guide compares published figures from several sources and lists what should be on the invoice. If a contractor quotes far above these ranges, ask for the breakdown before you sign.

What should you keep for the claim?

Keep the same three things for every temporary repair: photos before, photos after, and the receipt. The Florida DFS guide says to keep all receipts and take photographs of the damage before and after repairs, including emergency repairs, and submit them with your claim. The HO-3 form requires an accurate record of repair expenses.

• Photos of the roof damage from the ground and the attic or ceiling below it, before the tarp goes on.
• Photos of the finished tarp.
• Receipts for the tarp, boards, screws and plywood, or the contractor’s itemized invoice.
• The claim number, the date you reported the loss, and the name of each person you spoke to.
• Any wet ceiling, insulation or drywall below the hole, photographed before you remove it.

Water that came through the roof needs its own attention. If the ceiling is stained, soft or dripping, see our guide to ceiling water damage. Wet materials that stay wet for more than a day or two can grow mold.

Florida rules for roof tarps and roofing contracts

Florida law adds protections that matter the day a roofer knocks. Under Florida Statutes 489.147, a contractor may not offer you a rebate, gift, gift card, cash, coupon or a waiver of your insurance deductible in exchange for inspecting your roof or filing a roof claim. A contractor may not interpret your policy, advise you on coverage, or adjust your claim unless also licensed as a public adjuster. Any repair agreement must come with a good-faith, itemized estimate.

Timing matters too. If you sign a contract to repair or replace a roof within 180 days of a Governor’s emergency declaration covering your area, you may cancel it without penalty within 10 days after signing or by the official start date, whichever comes first. The statute defines the official start date to include a temporary repair to the roof covering made in compliance with the Florida Building Code. In plain terms, a “free tarp” installed under a signed roofing contract can end your cancellation window the same day. Cancel by certified mail or another method with proof.

The Florida Department of Financial Services runs an Insurance Consumer Helpline at 1-877-693-5236 and tells storm victims not to sign anything before calling. For door-to-door tactics, read our guide to storm chaser scams.

What comes after the tarp?

A tarp buys weeks, not months. HomeAdvisor and GAF both put its useful life at about three months, and FEMA designs Blue Roof covers for 30 days. Use that time to get the roof inspected, collect written estimates from licensed roofers, and move the claim along. Check the tarp after every storm and after high wind, and have loose boards or screws replaced rather than waiting for a leak to show up on the ceiling.

Our storm damage claim guide walks through the adjuster visit, and the hurricane damage guide explains which policy responds to wind, rain and surge. If a tree caused the hole, start with what to do when a tree falls on your house. If the power is out while you wait for repairs, read our generator safety rules before you start one.
