Tarping is temporary only — a properly installed tarp buys 30-90 days until professional repair; it is not a permanent solution Use 6-mil minimum blue polyethylene — thinner tarps tear in Florida winds; thicker (8-10 mil) is better for anything beyond a few days Extend the tarp 3+ feet beyond the damage — water runs downhill; covering only the visible hole misses the water entry path Secure with 1x2 or 2x2 lumber, NOT just sandbags — wind will lift sandbag-weighted tarps; lumber-screwed tarps hold through sustained winds Never go on the roof during a storm — wait for safe, dry, calm conditions; interior containment is the priority during active weather

When a Tarp Is the Right Call

An emergency roof tarp is a temporary, stop-gap measure. Its purpose is simple: keep water out of your home long enough for a professional roofer to perform a permanent repair.

You should tarp your roof when:

A storm has caused visible roof damage — missing shingles, a punctured section, displaced tiles, or torn membrane A leak is active and the source is identifiable from the ground — you can see the damaged area without climbing up Professional repair cannot happen immediately — the roofer is scheduled but can't arrive for hours or days A named storm is approaching — pre-storm tarping of known vulnerable areas can prevent damage

You should NOT tarp your roof when:

The roof is wet, windy, or lightning is present — climb hazards are extreme The damage is not visible or accessible — guessing where to place a tarp wastes time and materials The roof pitch is steep — slopes over 6:12 (26 degrees) are unsafe for untrained homeowners You don't have proper safety equipment — sturdy shoes, a harness for steep roofs, and a spotter on the ground

Materials You'll Need

Material: Blue polyethylene (poly) tarp — the standard woven plastic tarp available at any hardware store.

Thickness: Minimum 6-mil. In Florida's wind environment, 6-mil is the absolute floor. If you can find 8-mil or 10-mil, buy it. The price difference is marginal; the performance difference is enormous.

Size: The tarp should extend a minimum of 3 feet beyond the damaged area on all sides — upslope, downslope, and laterally. Water doesn't enter only at the hole; it enters at any point uphill of the breach and runs down into it.

For a single missing shingle area: a 6x8 foot tarp is sufficient For a larger damaged section (several feet across): a 10x12 or 12x20 foot tarp When in doubt, go bigger. Excess tarp material can be folded and trimmed. Too-small tarps are useless.

Fastening Materials

Wooden battens: 1x2 or 2x2 lumber strips, cut to lengths that span the tarp width. You'll need: One batten for the top edge (upslope) One batten for the bottom edge (downslope) One batten for each side edge Additional battens across the middle for large tarps (every 3-4 feet)

Roofing screws: 1-5/8 inch or 2-inch exterior-grade screws with neoprene washers (often called "Tek screws"). These penetrate the tarp, the batten, the shingle/deck, and the neoprene washer seals the screw hole. You'll need approximately one screw per linear foot of batten.

Alternative if lumber isn't available: In a pinch, heavy-duty bungee cords or rope can hold a tarp temporarily. These are significantly less secure than lumber-and-screw and should only be used for very short-term coverage (hours, not days).

Safety Equipment

Sturdy, rubber-soled shoes — no sandals, no smooth soles Work gloves — tarp edges and roof surfaces are abrasive Safety glasses — debris and screw fragments can fly A spotter on the ground — someone who can call 911 if something goes wrong A phone in your pocket — fully charged, with emergency contacts saved

Optional but Helpful

Roofing cement or mastic — seals the edges of the tarp to the roof surface for additional water resistance Duct tape — temporary edge sealing before screws go in A hammer or cordless drill/driver — for installing screws A utility knife — trimming excess tarp

Step-by-Step Emergency Tarp Installation

Step 1: Assess from the Ground First

Before climbing up, use binoculars or your phone's zoom camera to identify: The exact location and extent of the damage The safest access path to the damaged area Overhead hazards (power lines, tree limbs, loose chimney components) The roof pitch — if it looks too steep to walk on comfortably from the ground, it is

Step 2: Choose Safe Weather Conditions

Do NOT tarp during: Active rainfall Winds above 15-20 mph Lightning in the area Darkness (unless you have professional-grade lighting)

Wait for: Dry conditions Calm winds (under 10 mph) Daylight Clear weather forecast for at least the next few hours

If conditions are unsafe, perform interior containment only (buckets, towel dams, controlled ceiling release) and wait for professional tarping.

Step 3: Access the Roof Safely

Use a sturdy, properly positioned ladder that extends 3 feet above the roof edge Have your spotter hold the ladder base Step onto the roof carefully, testing each foothold Stay aware of your position relative to the roof edge at all times

Step 4: Position the Tarp

Critical: The top edge of the tarp must be placed UPSLOPE (higher) than the damage.

Water flows downhill. If the top edge of the tarp is at or below the damage point, water will flow over the tarp edge, under the tarp, and into the damage — exactly what you're trying to prevent.

Unfold the tarp on the ground to confirm it's large enough Carry the folded tarp to the roof and unfold it over the damaged area Position it so the tarp extends a minimum of 3 feet above the damage, 3 feet below, and 3 feet on each side Smooth out wrinkles and ensure the tarp lies flat against the roof surface

Step 5: Secure the Top Edge First

The top edge is the most critical. If wind gets under the top edge, the entire tarp will peel off.

Fold the top edge of the tarp over a 1x2 or 2x2 batten — the batten should be on TOP of the tarp, not underneath Position the batten so it's entirely upslope of the damaged area Drive roofing screws through the tarp and batten into the roof deck every 12 inches along the batten Screws should be snug but not overtightened — you want the neoprene washer to compress and seal, not tear through the tarp

Step 6: Secure the Side Edges

Fold each side edge over a batten Secure with screws every 12 inches Ensure the side battens extend to or beyond the roof ridge if the damage is near the peak

Step 7: Secure the Bottom Edge

Fold the bottom edge over a batten Secure with screws every 12 inches The bottom edge should extend well past the damage — water running down the roof should hit the tarp surface, not the exposed roof

Step 8: Add Cross-Battens for Large TarPs

If the tarp is wider than 6 feet, add horizontal battens across the middle (perpendicular to the slope) every 3-4 feet. These prevent wind from billowing the tarp and peeling it off.

Step 9: Seal the Edges (Optional)

For extended temporary coverage (multiple weeks), apply roofing cement or mastic along the top and side edges of the tarp where it meets the roof surface. This creates a water-resistant seal that prevents wind-driven rain from creeping under the edges.

Step 10: Inspect from the Ground

Once you're back on the ground, look up at the tarp from multiple angles: Is it flat and tight against the roof surface? Do all edges appear secured? Does the tarp fully cover the damage zone with adequate overlap? Are there any loose flaps that could catch wind?

Adjust as needed before considering the job done.

Common Tarping Mistakes That Make Things Worse

Mistake 1: Using a Tarp That's Too Small

A tarp that barely covers the visible damage will let water in from every direction. Water enters uphill of the damage and flows down into it. The tarp must cover the damage AND the area above it.

Mistake 2: Placing the Tarp Edge at the Damage

The top edge of the tarp must be ABOVE (upslope of) the damage. An edge at the damage line is an open door for water.

Mistake 3: Using Sandbags or Bricks Instead of Screws

Weight-only fastening is inadequate for anything beyond a few hours. Wind lifts the tarp edge, sandbags slide, and the tarp becomes a sail. Screws through battens are the only reliable method.

Mistake 4: Using Thin, Cheap Tarps

The $10 3-mil tarp from the dollar store will shred in the first sustained wind event. Minimum 6-mil poly, preferably 8-mil or heavier.

Mistake 5: Nailing Through the Tarp Without Battens

Individual nails or screws without battens tear through the tarp material under wind load. Battens distribute the holding force across the tarp edge.

Mistake 6: Leaving the Tarp Permanently

A tarp is a temporary fix. UV degradation breaks down polyethylene within 60-90 days in Florida sun. A degraded tarp shreds, leaves debris on your roof, and no longer protects anything. Schedule permanent repair promptly.

How Long Can a Tarp Stay On

Recommended maximum: 30-90 days.

Blue poly tarps are not UV-stabilized for long-term exposure. In Florida's intense sun:

Weeks 1-4: Tarp performs well if properly installed Weeks 4-8: UV degradation begins; the tarp becomes brittle and may crack Weeks 8+: Significant degradation; the tarp may shred and leave plastic fragments embedded in your roof surface

Schedule permanent repair within the first 30 days of tarping. The tarp is a bandage — not a cure.

Frequently Asked Questions

What size tarp do I need for a roof leak?

The tarp should extend a minimum of 3 feet beyond the damaged area on all sides — above, below, and laterally. For a typical single-shingle damage area, a 6x8 foot tarp works. For larger damage, use 10x12 or 12x20 feet. When uncertain, choose a larger tarp.

Can I tarp a roof by myself?

It's possible for small, accessible damage areas on low-slope roofs. However, having a second person on the ground as a spotter is strongly recommended for safety. For steep roofs, large damage areas, or any situation where you feel unsafe, call a professional.

Does homeowner's insurance cover emergency roof tarping?

In most cases, yes. Emergency measures to prevent further damage after a covered peril (windstorm, hail, fallen tree) are typically covered under your homeowner's policy. Keep receipts for all materials and document the damage with photos before and after tarping.

What's the difference between a blue poly tarp and a heavy-duty contractor tarp?

Blue poly tarps are woven polyethylene with reinforced edges — lightweight and adequate for short-term emergency use. Contractor tarps are typically 10-12 mil thick, heavier, more puncture-resistant, and last longer under UV exposure. For anything beyond a few days of coverage, invest in a heavier tarp.

Can I tarp a flat roof the same way?

Flat roof tarping is different. Instead of screwing through battens, the tarp edges are weighted with sandbags or lumber along all four sides. The tarp must still extend well beyond the damaged area. Flat roof membranes are more easily punctured by screws, so fastening methods differ. If you have a flat roof leak, call a professional for proper temporary coverage.
