New Castle County — Wilmington, Newark, and Middletown in northern Delaware — takes hurricane remnants, tornadoes, and Delaware River and creek flooding from the storms that reach the I-95 corridor.
Storm damage on New Castle County roofs
New Castle County roofs face real storm exposure — and the most expensive damage is often invisible from the ground.
The remnants of Hurricane Ida (2021) spawned tornadoes and brought severe flooding to New Castle County, and Hurricanes Isabel (2003) and Floyd (1999) flooded creeks and the Delaware River corridor. Nor'easters and the 2012 derecho added wind and tree damage. The county's dense population means heavy post-storm roofing demand.
🌀 New Castle County storm history
Ida's 2021 remnants brought tornadoes and flooding; Isabel (2003), Floyd (1999), and nor'easters caused earlier wind and flood damage.
📋 New Castle County building & wind code
Delaware administers building codes and permits at the county and municipal level — New Castle County, Kent County, and Sussex County each run their own permitting — with coastal Sussex enforcing high-wind requirements for the beach communities. Every reroof needs a permit from the local authority. As the lowest-lying state, Delaware pairs wind exposure with serious flood risk, so building to current wind standards and proper flashing detail matters.
Storm-ready roof types in New Castle County
The right roof here balances wind rating, impact resistance, and coastal durability.
Architectural shingle
Most common. Class 4 impact-rated shingles resist wind and hail and may earn an insurance credit.
Metal roofing
Excellent wind and salt-air resistance — a strong fit for storm-prone coastal Delaware.
Tile & specialty
Durable but heavier; needs a structural review and proper wind detailing after any impact.

Storm roof claims in New Castle County
In low-lying Delaware, the key claim question is often which policy applies — wind or flood.
Wind and wind-driven-rain roof damage is covered by your homeowner policy, and coastal policies may carry a separate hurricane or wind deductible. Flood damage — a serious risk in the nation's lowest-lying state, from Sandy to recurring nor'easters — is NOT covered by a homeowner policy and needs separate flood insurance (NFIP). Document everything with dated photos and get a licensed contractor's written report.
💧 Wind vs. flood in Delaware
Delaware is the lowest-lying state, and much of its worst storm damage — from Hurricane Sandy to powerful nor'easters — comes from coastal and tidal flooding, which a homeowner or wind policy does not cover; rising water needs separate flood insurance (NFIP). Wind and wind-driven-rain roof damage is covered. After a storm, document both, and have a licensed roofer separate wind damage from flood damage in writing.

How to verify a roofer in New Castle County
Delaware has no statewide roofing license — but it gives you a clear way to vet anyone who knocks after a storm.
Every contractor must register as a Construction Contractor and hold a Delaware business license from the Division of Revenue, and out-of-state contractors must also register as non-residents and post a surety bond — 6% of the contract price on jobs of $20,000 or more — a rule aimed squarely at storm-chasers. You can look up any contractor in the Delaware Division of Revenue's business license search; verify it before signing, confirm liability and workers' compensation insurance, and get the scope and price in writing.
