Emergency board-up and tarping is the single most important step between storm damage and full restoration. According to the EPA, mold can begin growing on wet building materials within 24 to 48 hours of moisture exposure. Every hour that a damaged roof or broken window allows rain, wind, and debris into your home increases restoration costs by creating secondary damage that compounds on top of the original storm impact. Professional emergency mitigation costs $500 to $3,000 on average, but it prevents $10,000 to $50,000 in additional water, mold, and structural damage.
What Emergency Board-Up and Tarping Actually Involves
Emergency mitigation has two primary components, and both serve the same purpose: stopping additional damage until permanent repairs can begin.
Board-up means securing openings in your home’s exterior with plywood or OSB (oriented strand board). This covers broken windows, damaged doors, holes in walls, and any other breach that allows weather, animals, or unauthorized access into your home. Professional crews use 5/8-inch or 3/4-inch plywood, securing panels with tapcon screws into masonry or lag bolts into framing. Board-up differs from nailing a sheet over a hole. Proper installation creates a weather-resistant seal that handles ongoing wind and rain exposure.
Tarping covers damaged roofing areas with heavy-duty polyethylene tarps, typically 6-mil thickness or greater, anchored with 2×4 lumber, sandbags, or mechanical fasteners. According to the National Roofing Contractors Association, a properly installed emergency tarp should withstand winds up to 50 mph and remain functional for 30 to 90 days while permanent repairs are scheduled.
The Restoration Industry Association reports that emergency mitigation within the first six hours reduces total claim costs by an average of 40% compared to properties where mitigation was delayed 24 hours or more. That’s the financial case for speed.
“Emergency tarping isn’t a repair. It’s triage,” says Jeff Cross, former editor of Cleanfax Magazine and restoration industry consultant. “The goal is to stabilize the building so that permanent repairs can happen under controlled conditions rather than racing against weather.”
When You Need Emergency Board-Up and Tarping
Not every storm event requires professional emergency mitigation. Here’s how to assess whether your situation warrants an immediate call:
Call immediately if:
- Your roof has visible holes, missing sections, or exposed decking
- Windows or doors are broken or missing
- Walls have been breached by fallen trees or flying debris
- Water is actively entering your home through storm-created openings
- Your home’s structural integrity appears compromised
Can wait until morning if:
- Damage is limited to shingles that are cracked but still attached
- Minor siding damage with no wall penetration
- Gutter damage without roof compromise
- Cosmetic damage to exterior trim or shutters
According to FEMA guidelines, your insurance policy requires you to take “reasonable steps” to prevent additional damage after a covered loss. Failing to mitigate puts your claim at risk. If an insurer determines that secondary damage occurred because you didn’t protect the opening, they can reduce or deny that portion of your claim.
The Emergency Tarping Process
Professional roof tarping follows a specific sequence that balances speed with safety and effectiveness.
Assessment (15-30 minutes). Crews evaluate roof access points, identify all damaged areas, measure tarp requirements, and check for structural hazards like weakened trusses or unstable decking. They also assess wind conditions and determine whether tarping can proceed safely or needs to wait for conditions to improve.
Material staging (15-20 minutes). Standard emergency tarp kits include 6-mil or heavier poly tarps, 2×4 anchor boards cut to length, fasteners appropriate for the roof material, and safety equipment. Commercial restoration crews carry pre-cut materials for common roof dimensions to reduce setup time.
Installation (1-3 hours per damaged area). The tarp must extend at least 4 feet past the damaged area on all sides, drape over the ridge if near the peak, and be anchored securely enough to resist wind uplift. Anchor boards are screwed through the tarp into the roof deck at 24-inch intervals along each edge.
Documentation (10-15 minutes). Before and after photos from multiple angles with timestamps create the record your insurance company needs. This documentation proves the mitigation happened and supports the reimbursement claim for emergency services.
Average costs for professional emergency tarping:
| Service | Typical Cost | Notes |
|---|---|---|
| Small tarp (up to 100 sq ft) | $300 – $700 | One or two damaged areas |
| Medium tarp (100-300 sq ft) | $700 – $1,500 | Multiple areas or steep pitch |
| Large tarp (300+ sq ft) | $1,500 – $3,000+ | Significant roof damage |
| Board-up per opening | $100 – $400 | Depends on size and access |
| After-hours emergency fee | $150 – $500 | Evenings, weekends, holidays |
The Board-Up Process
Securing non-roof openings requires different techniques depending on the opening type and surrounding construction materials.
Windows and glass doors. Measure the opening, cut plywood 4 inches wider and taller than the frame on each side, and secure with tapcon screws into masonry or lag screws into wood framing. For sliding glass doors, install vertical bracing in addition to the plywood panel. According to industry best practices, boards should be weather-sealed at edges with caulk to prevent moisture infiltration around the plywood.
Wall breaches. Holes from falling trees or large debris require framing support before plywood installation. Crews assess whether wall studs are intact, add temporary framing where needed, and install plywood panels that bridge from undamaged structure on each side of the opening.
Door entries. Damaged doors are either secured in their frame with additional hardware or replaced with plywood panels. If the door frame itself is damaged, temporary posts support the header while plywood covers the entry.
Professional board-up includes checking for and shutting off any utilities exposed by the damage, which is critical for both safety and preventing additional water damage from broken pipes.
DIY vs. Professional Emergency Mitigation
After a storm, your instinct may be to grab a tarp and start covering the damage yourself. Here’s an honest assessment of when that makes sense and when it doesn’t.
DIY can work for:
- Ground-level window board-ups on single-story homes
- Small areas of siding damage accessible without ladders
- Temporary interior water containment with buckets and towels
Professional service is necessary for:
- Any roof work (fall injuries send 500,000+ Americans to emergency rooms annually, according to the Bureau of Labor Statistics)
- Multi-story openings requiring ladder or lift access
- Structural damage where stability is uncertain
- Situations where documentation is needed for insurance claims
“The number one cause of injury during storm recovery isn’t the storm itself. It’s homeowners climbing on damaged roofs to install tarps,” says Tom Coulter, Director of Training at the IICRC. “Wet, debris-covered roofing with potential structural compromise is the worst possible surface to work on without training and safety equipment.”
If you do handle ground-level board-up yourself, use plywood rated for exterior use, secure panels into structural framing rather than siding or trim, and photograph your work for insurance documentation. Save all material receipts for reimbursement through your insurance claim.
How Insurance Covers Emergency Mitigation
Emergency board-up and tarping falls under your policy’s “duty to mitigate” clause. This means your insurer not only expects you to take protective measures but will pay for them as part of your claim.
Key points about mitigation coverage:
Your emergency mitigation costs are separate from your damage claim and typically don’t count against your deductible. According to the Insurance Information Institute, most standard policies cover reasonable mitigation expenses without a separate deductible application.
Keep detailed records of everything: receipts for materials, invoices from service providers, photographs of the work, and a timeline of when services were performed. Your restoration company’s documentation becomes part of the insurance record.
Don’t wait for insurance approval before mitigating. Your policy requires prompt action. File the claim and proceed with mitigation simultaneously. The adjuster will review mitigation costs during the claim process.
Finding Emergency Storm Damage Services
When storms hit, response time matters. Build your emergency contact list before you need it:
Look for restoration companies with 24/7 emergency response capabilities and a guaranteed response time (industry standard is 1 to 4 hours). Verify they carry proper licensing and insurance for your state. Check for IICRC certification in applied structural drying and water damage restoration. Confirm they have insurance claim experience and can document their work in a format adjusters accept.
According to BrightLocal’s 2024 consumer survey, 76% of people who search for emergency services on their phone contact a business within 24 hours. Having a trusted local provider identified before storm season eliminates the pressure of choosing under duress.
Frequently Asked Questions
How long can an emergency tarp stay on my roof?
Professional-grade tarps installed correctly can protect your roof for 30 to 90 days. UV exposure and wind stress degrade the material over time, so permanent repairs should be scheduled as quickly as contractor availability allows. In areas with extended contractor wait times after widespread storms, tarps may need replacement before permanent repairs begin.
Will my insurance pay for emergency tarping even if I haven’t filed a claim yet?
Yes. Mitigation is expected before formal claim processing begins. Document the work, save receipts, and submit them when you file your claim. Insurers reimburse reasonable emergency mitigation costs as a standard part of storm damage claims.
Can I get my own tarp from a hardware store and install it?
For ground-level or low-slope applications, a heavy-duty tarp from a hardware store can provide temporary protection. For roof applications, professional installation is strongly recommended due to safety risks and the need for proper anchoring. Improperly installed tarps can blow off in subsequent winds, causing the exact secondary damage you’re trying to prevent.
What happens if another storm hits while my tarp is up?
A properly installed emergency tarp should withstand winds up to 50 mph. If a more severe storm is forecast, contact your restoration company about reinforcing or replacing the tarp beforehand. Any additional damage from subsequent storms is typically covered as a separate claim event.
How quickly should I expect a response for emergency board-up?
Industry standard for emergency restoration response is 1 to 4 hours. After widespread storm events affecting many properties, response times may extend to 6 to 12 hours due to demand. Companies with larger crews and pre-staged materials in storm-prone areas typically respond faster.
Does boarding up my house affect my insurance claim?
Board-up supports your claim, it doesn’t hurt it. Insurance policies require you to take reasonable steps to prevent additional damage. Documented board-up demonstrates compliance with your policy’s mitigation requirements and can actually strengthen your claim.
