Storm Damage Restoration Glossary & Terminology Guide

A hail impact assessment is a professional inspection conducted after a hailstorm to evaluate the extent of damage inflicted on your roof, siding, gutters, and other exterior surfaces. Inspectors look for dents, bruising, cracked shingles, and granule loss. This assessment is a critical first step in any storm damage restoration process and is typically required to support an insurance claim.

Structural compromise refers to any weakening or damage to the load-bearing components of your home caused by storm forces such as high winds, falling debris, or heavy snow accumulation. In roofing, this may include cracked rafters, damaged decking, or displaced trusses. Identifying structural compromise early is vital, as unresolved damage can escalate into significant safety hazards and costlier repairs.

Roof decking — also called sheathing — is the flat board material that forms the base layer of your roof system, installed directly on top of the structural rafters. During storm events, water intrusion through damaged shingles can saturate and rot the decking, requiring full or partial replacement. Damaged decking must be addressed during restoration before new roofing materials are installed.

An insurance adjuster is a licensed professional sent by your insurance company to inspect storm-related damage and determine the scope and monetary value of your claim. Their report directly influences how much you receive in compensation. Homeowners are advised to have a trusted roofing contractor present during the adjuster’s visit to ensure all damage — including less visible or secondary damage — is properly documented.

A supplemental claim is an additional insurance claim filed after the initial settlement when new or previously undiscovered storm damage is identified during the restoration process. This commonly occurs when hidden damage — such as compromised underlayment or deteriorated flashing — is uncovered once roofing materials are removed. Filing a supplement ensures that all legitimate damage is fully covered under your policy.

Wind uplift is the upward force exerted by high winds that can detach or peel back roofing materials, including shingles, flashing, and membrane systems. During severe storms, negative pressure created by wind can lift entire sections of a roof. Understanding wind uplift explains why some storm damage appears on surfaces not directly exposed to wind, and why proper installation and fastening techniques are critical to roof longevity.

Flashing refers to the thin strips of metal — typically galvanized steel or aluminum — installed at roof joints, valleys, chimneys, and skylights to create a watertight seal. Flashing failure occurs when storms cause these strips to lift, crack, or pull away from their sealed positions, creating entry points for water. Left unaddressed, failed flashing is one of the most common causes of interior water damage following a storm event.

Temporary mitigation encompasses the emergency protective measures taken immediately after storm damage to prevent further deterioration of your property before permanent repairs can be completed. Common examples include tarping exposed roof sections, boarding up broken windows, and applying sealant to vulnerable areas. Insurance policies often require prompt temporary mitigation to limit additional damage, making it a standard first step in the restoration process.
