Sandown NH Emergency Roofing: Install a Temporary Roof Tarp

Estimated Read Time: 12 minutes

If wind or a fallen limb opened a leak, you need a safe, quick way to stop water now. This guide shows you how to install a temporary roof tarp the right way so you can protect your home until permanent repairs. We cover tools, safety, step-by-step setup, and mistakes to avoid. If you prefer help, we provide emergency tarping and leak containment with free inspections across southern NH and northern MA.

Before You Start: Safety First

Stopping a leak matters, but your safety matters more. Roof surfaces are slippery after rain, and Nor’easter gusts in places like Nashua and Manchester can change fast. If conditions are windy, icy, or lightning is present, wait or call a pro.

Follow these safety rules:

1. Use a harness, roof anchors, and a stable extension ladder that extends 3 feet past the eave.
2. Wear non-slip boots, cut-resistant gloves, and eye protection.
3. Work with a partner for ladder footing and tool handoffs.
4. Never step on loose shingles, skylight lenses, or wet metal.
5. Keep children and pets clear of the drop zone.

Hard facts to guide your decision:

• Industry certifications indicate verified best practices. Our crews are CertainTeed Select ShingleMaster and Owens Corning Platinum Preferred certified.
• Preventive care reduces emergencies. We recommend scheduling roof inspections every six months to catch issues before storms.

What You Need to Tarp a Roof

A proper temporary tarp requires the right materials. Gather these before climbing:

• 6 mil or heavier polyethylene tarp large enough to cover damage and extend 3–4 feet in all directions
• 2x4 furring strips for edge battens
• Exterior-grade screws or nails with plastic caps for better hold and reduced tearing
• Roofing nails for shingle areas when needed
• Utility knife and heavy-duty shears
• Hammer or drill-driver with impact bits
• Measuring tape, chalk line, and marker
• Roofing cement for minor shingle sealing if dry
• Duct tape or gaffer tape to wrap sharp edges of the tarp near gutters

Pro tip: Dark tarps can expand in direct sun. Pull snug, but not overstretched, so temperature changes do not tear grommets.

Step 1: Identify and Mark the Damaged Area

Leaks often show up indoors far from the roof entry point. Start inside the attic:

1. Trace the wet path upward to the roof deck. Look for stained sheathing, wet insulation, or active drips.
2. On the roof, locate missing or torn shingles, punctures from branches, or lifted flashing.
3. Mark the area and measure so your tarp will cover the damage and extend past the ridge or at least 3–4 feet downslope and side-to-side.

Document the damage with photos and video. If you plan to open an insurance claim, this evidence and a contractor’s inspection report can speed approval. We can work with your carrier and provide inspection documentation.

Step 2: Clear Debris and Stabilize

Before placing the tarp, remove hazards and loose materials:

1. Carefully clear branches, leaves, and shingle pieces. Do not pry embedded nails that could widen holes.
2. If decking is punctured, do not stand over the hole. Bridge it with a 2x6 if you must cross.
3. If water is actively flowing, place a bucket inside under the drip and poke a small hole in bulging ceiling paint to relieve pressure.

If gutters are overflowing from debris, clear the downspouts so trapped water does not back up under the tarp later. Consider a clog-resistant system to reduce future emergency overflows. Some systems are guaranteed to never clog, sag, or pull away.

Step 3: Choose the Tarp Layout for Your Roof

How you position the tarp matters more than the fasteners:

• Best practice: If possible, run the tarp over the ridge. Water sheds downhill, and a ridge-overlap reduces backflow.
• If ridge coverage is not possible: Start several feet above the damage so water flows onto the tarp, not under it.
• Avoid placing grommets at high-tension points. Instead, secure tarp edges using 2x4 battens.

On low-slope or flat sections, pitch the tarp to a gutter. Prevent standing water with a slight downhill grade.

Step 4: Secure the Up-Slope Edge First

The up-slope edge carries the highest risk of wind-lift and water entry.

1. Roll the tarp out so it extends at least 3 feet above the damage.
2. Lay a 2x4 along the up-slope edge of the tarp. Roll the tarp around the 2x4 once to create a reinforced hem.
3. Fasten the 2x4 through the roof deck into rafters where possible using exterior screws spaced 8–12 inches apart. If you cannot hit rafters, increase fastener count to distribute load.
4. Keep fasteners outside of the damaged, rotten, or soft areas so they hold firm.

This batten method resists tearing better than using only grommets.

Step 5: Secure the Sides and Down-Slope Edge

With the up-slope edge anchored, finish the perimeter:

1. Pull the tarp tight across the damage and align it toward the gutter.
2. Install 2x4 battens on each side. Maintain even tension without overstretching.
3. On the eave, use another 2x4 batten. Wrap the tarp around the wood once, then fasten.
4. If wind exposure is high, add a second row of fasteners 3–6 inches inboard of the edge to reduce flutter.

Seal small shingle tabs with roofing cement if the surface is dry. Do not rely on caulk alone for structural holes or flashing failures.

Step 6: Protect Penetrations, Valleys, and Flashing

Vents, chimneys, and valleys need extra attention:

• Vents: Cut an X in the tarp where it meets the vent. Slide the vent through, then lap a small square of tarp over the vent flange and tape the seams. Do not block vent openings.
• Chimneys and skylights: Extend the tarp at least 12 inches up the sides. Use battens on the tarp edges, not on flashing.
• Valleys: Run the tarp across the valley in the direction of water flow and continue it several feet beyond to avoid a dam.

If you see cracked rubber boots at plumbing vents or failed step flashing, note them for permanent repair. These are common leak sources in New England homes.

Step 7: Check for Leaks and Secure Loose Areas

Once secured, test your work:

1. Hose-test gently from the top down for five to ten minutes while a partner checks the attic.
2. If drip points remain, tighten the tarp, add fasteners, or adjust overlaps.
3. Trim excess tarp and tape any cut edges to reduce wind fray.

Plan a permanent repair or replacement quickly. A tarp is temporary. Pro teams can often restore shingles, flashing, and underlayment the same week, weather permitting.

When to Call a Professional Immediately

DIY tarping is not safe or practical in some cases:

• Structural damage, sagging rafters, or a hole you cannot span safely
• Leaks near electrical service masts or damaged power lines
• Wet, icy, or steep roofs where footing is poor
• Widespread wind or hail damage across multiple slopes

We provide emergency tarping and immediate leak containment. Our crews respond quickly to assess damage and begin repairs. Free inspection and detailed estimates are part of the visit, and we can help streamline the insurance claim with photos and reports.

Tarping on Different Roof Types

Matching your approach to the roof type improves results.

• Asphalt shingle: Use batten boards and screws. Avoid lifting large sections of shingles in cold weather to prevent cracking.
• Metal: Do not drill at standing seams. Use battens at edges and attach to decking where possible. Add foam blocks to relieve sharp edges.
• Low-slope membranes: Avoid adhesives that may conflict with the membrane. Use weighted battens at edges and ensure positive drainage.
• Rubber roofs: Fasten to substrate at edges only. Do not puncture active membrane areas more than necessary.

If your home includes a porch with rolled roofing or a flat addition, focus on water flow to gutters to prevent ponding under the tarp.

Preventing the Next Emergency

Most emergency calls we see in Lowell, Methuen, and Derry follow heavy wind or ice. Reduce risk with a simple plan:

1. Schedule semi-annual inspections, ideally spring and fall.
2. Keep gutters and downspouts clear before storm season. Consider a heavy-duty, clog-free system to prevent backups.
3. Trim overhanging branches within safe clearance of the roof.
4. Address small issues early, like lifted shingles or cracked vent boots.
5. Consider shingle rejuvenation to extend life if granule loss is visible.

Hard fact: We back many replacements with a workmanship warranty, and our credentials unlock top manufacturer warranties from prime brands. That means better coverage when you need it most.

Insurance Tips for Storm Damage

A clean paper trail improves claim outcomes:

1. Take timestamped photos before placing the tarp and after it is secured.
2. Save all receipts for materials and emergency work.
3. Get a written inspection report and a line-item estimate. We provide both at no cost.
4. Do not remove damaged materials before the adjuster visit unless safety requires it.

We can meet your adjuster on site in Manchester, Nashua, Lowell, and nearby cities to review the findings and help align scope with actual damage.

Common Tarping Mistakes to Avoid

Learn from the top issues we repair after storms:

• Using only grommets. They rip out in wind. Batten boards spread the load.
• Stopping the tarp at or below the leak. Always extend upslope.
• Trapping water. Always pitch toward a gutter and keep downspouts clear.
• Puncturing good membrane areas excessively on low-slope roofs.
• Working alone. A second set of hands prevents ladder falls and tarp sail-ups.

If you spot interior bulging drywall, relieve it with a tiny drain hole into a bucket to prevent a ceiling collapse. Then address the roof.

When a Tarp Is Not Enough

Sometimes the safest and fastest fix is a targeted repair or partial replacement:

• Missing shingles across large fields after wind or tree damage
• Hail bruising with widespread granule loss
• Aged roofs near end of service life

In these cases, we mobilize crews quickly to remedy damaged or missing shingles, fix leaks, and restore your system. Final cleanup and a post-service inspection ensure the site is tidied and the repair is sound.

What Homeowners Are Saying

"It was a dark and stormy night when a lone shingle of mine decided to make an escape attempt… it didn’t get very far because I found it in my yard the next day. I decided to call in the experts though since I wasn’t sure if any of my other shingles were going to get the bright idea to try and fly off whenever the wind blew just right. The team came out within just a few days after my initial call. Tyler was incredibly thorough with his assessment and let me know (with exceptional detail and documentation of the state of the roof ...) The courtesy, professionalism, and cost effectiveness from Adam Vaillancourt Roofing was leagues above the other consultation I had done. ... Tim and the project/install team did exceptional work ... Needing a new roof or roof repair is not a particularly fun nor enjoyable task associated with homeownership, but my experience with Adam Vaillancourt Roofing made this decision almost entirely stress-free and easy. Throughout the entire process I felt confident that I would receive honest and high-quality work for my home and Adam Vaillancourt Roofing delivered nothing but the best."
–C. D., Roof Repair

"Just had our roof done, although they found problems that couldnt be avoided Kieth the project manager got right on top of it and walked us through to the right solution, they fixed the trouble spots and fixed it to prevent future problems. Hectors roof team knew how to handle all aspects roofing including the rubber roof we had to have done and the siding that needed to be replaced because of that roof. Adam valincourt roofing was the only people we called that took the time to go up on the roof and explained the problems and how to fix them letting us decide the final plan and materials to use"
–Dave D., Roof Repair

"We just had our roof replaced by Juan, the project manager, and his crew. I must say, I am beyond pleased - not just with the final product but with the overall process. ... Brad did the inspection and was very detailed - I did not feel rushed during the initial appointment and every follow-up question was answered expeditiously. The projected timeframe to get scheduled was on the dot ... Upon arrival, his crew got straight to work - I was very impressed by how fast and methodically they moved. Once completed, Juan showed me the pictures I had requested (for peace of mind of the areas I couldn't see for myself), did a walkthrough and explained what they did in various areas to ensure a quality result, and did a final sweep before he left the site ... Thank you guys for a great experience!!"

Frequently Asked Questions

How long can a temporary roof tarp stay in place?

A tarp is a stopgap, not a repair. Aim for days to a few weeks. Schedule permanent repairs as soon as weather clears and materials are available.

What size tarp should I use for storm damage?

Choose a tarp that extends at least 3–4 feet beyond the damaged area on all sides. If possible, run it over the ridge for better water shedding.

Is it better to nail or screw a roof tarp?

Use exterior-grade screws with 2x4 battens along edges for stronger hold and less tearing. Grommet-only installs fail faster in wind.

Will insurance reimburse emergency tarping?

Often yes, when related to covered storm damage. Keep receipts and photos. A contractor inspection report can help your claim.

Can I tarp a roof in the rain?

It is risky. Wet surfaces are slippery, and fasteners seal poorly. Wait for a safer window or call an emergency crew with safety gear.
