Emergency Board-Up and Tarping After Storm Damage
Emergency board-up and tarping are the first protective interventions applied to a storm-damaged structure before permanent repairs begin. This page covers what these measures are, how contractors execute them, the storm scenarios that trigger their use, and the criteria that determine which approach — or combination — is appropriate. Understanding the scope and limits of these temporary measures is foundational to managing storm damage restoration from the first hours after an event through the insurance and repair process.
Definition and scope
Emergency board-up refers to the installation of rigid panel material — most commonly 5/8-inch OSB (oriented strand board) or plywood — over openings created or enlarged by storm damage: broken windows, compromised entry doors, breached garage panels, and holes in exterior walls. Tarping refers to the application of polyethylene or polyvinyl sheeting over damaged roof sections to prevent water infiltration until permanent roof damage restoration can be completed.
Both measures fall under the category of "temporary repairs" as defined in standard property insurance policy language and are distinct from permanent restoration in both material and code standing. The International Building Code (IBC), maintained by the International Code Council (ICC), does not govern temporary protective measures in the same way as permanent construction, but local jurisdictions may impose minimum standards for how board-up materials are secured and how long temporary tarps may remain before a permit-required repair is mandated.
These interventions directly affect storm damage moisture and mold risk: a structure left open for 24 to 48 hours in humid conditions can begin developing mold colonies, which FEMA's technical guidance identifies as a secondary loss multiplier in post-storm scenarios (FEMA P-909).
How it works
The execution sequence for emergency board-up and tarping follows a structured workflow:
- Damage assessment and hazard identification — A field technician surveys the structure for immediate life-safety hazards: downed power lines, structural instability, gas odors, or compromised load-bearing elements. OSHA's General Industry Standard 29 CFR 1910 and Construction Standard 29 CFR 1926 govern worker safety on storm-damaged sites (OSHA).
- Documentation — All visible damage is photographed and measured before any protective material is installed. This step feeds directly into storm damage documentation best practices and supports the insurance claim record.
- Opening sizing and material cutting — Panels are cut to cover each opening with a minimum overlap of 6 inches on all sides onto undamaged framing or masonry, ensuring the barrier is anchored to structural substrate rather than damaged material.
- Fastening — Panels are secured with exterior-rated screws or ring-shank nails at intervals not exceeding 8 inches along the perimeter. Adhesive foam is used to seal panel edges against wind-driven rain.
- Roof tarping — Tarps are laid from the ridge downward with a minimum 18-inch overhang past the eave line. Battens — dimensional lumber strips — are screwed through the tarp into undamaged decking at 24-inch intervals to prevent wind uplift. Heavy-duty tarps rated at 6 mil or greater thickness are the industry baseline for roof applications.
- Site documentation closeout — Installed measures are photographed in place, material quantities are recorded, and a written scope is provided to the property owner for submission to the insurer.
The distinction between professional temporary repair and an ad hoc homeowner patch matters under policy terms: storm damage insurance claims typically reimburse reasonable and necessary temporary repair costs, but improperly installed measures that accelerate damage may be denied or reduce the covered loss.
Common scenarios
Emergency board-up and tarping are triggered by identifiable storm event types, each presenting characteristic opening patterns:
- Wind and tornado events — Racked or missing doors, shattered windows, and wall sections displaced by positive and negative pressure cycles. Wind damage restoration and tornado damage restoration both commonly require full first-floor board-up when structural openings are widespread.
- Hurricane landfall — High-volume window and door failures across entire building facades, combined with partial roof decking loss. Hurricane damage restoration projects may require tarping of 30% to 60% of total roof area in severe cases, depending on wind zone exposure per ASCE 7 minimum design loads (ASCE).
- Hail impact — Punctured roof membrane sections on low-slope commercial roofs; residential asphalt shingle fields with compromised water-shedding capacity. See hail damage restoration for the broader repair context.
- Ice storms and winter weather — Ice dam formation causes water to back up under shingles and through fascia, creating interior ceiling penetrations that require tarping from the exterior and sometimes interior plastic sheeting as a secondary barrier. Ice storm damage restoration cases often combine tarping with emergency drying equipment deployment.
Decision boundaries
The choice between board-up alone, tarping alone, or both depends on three variables: the location of the breach (vertical vs. horizontal surface), the material integrity of the surrounding substrate, and the expected duration before permanent repair begins.
| Scenario | Primary measure | Supplemental measure |
|---|---|---|
| Broken windows, intact roof | Board-up | None required |
| Roof deck loss, no wall openings | Tarping | None required |
| Combined roof and wall damage | Tarping | Board-up |
| Structural wall compromise | Board-up with shoring | Engineering assessment required |
When substrate damage extends beyond what fasteners can grip — as in cases where a wall top plate has separated or decking is delaminated — temporary measures alone are insufficient and a structural damage assessment must precede any protective installation.
The boundary between temporary repair and permanent restoration is addressed directly in the temporary repairs vs. permanent restoration framework: temporary measures do not satisfy building permit requirements, do not restore code-compliant occupancy, and do not substitute for licensed contractor repairs under state contractor licensing rules. Verification of a contractor's qualifications before engaging for emergency services is covered under storm restoration contractor qualifications.
