Water Damage Insurance Claim on Long Island: What's Covered & How to File

By Greene Group Construction Corp · Nassau & Suffolk County Roofing Experts

Water damage is the second most common homeowners insurance claim in New York — but coverage is not automatic. Whether your claim gets approved, and for how much, depends entirely on the source of the water, how quickly you act, and how well you document your loss. This guide gives Long Island homeowners a clear picture before they pick up the phone. For immediate action steps, see our guide on what to do after water damage on Long Island.

What Homeowners Insurance Covers

How to File a Water Damage Claim: Step by Step

1. Stop the water source and make emergency protective repairs to prevent further damage.
2. Document everything with photos and video before any cleanup — source, all affected areas, damaged belongings.
3. Call your insurer to open a claim and get a claim number. Note the adjuster's name.
4. Call a restoration contractor before the adjuster arrives. Having a professional's written scope protects you if the adjuster understimates the damage. Greene Group provides detailed written assessments at no charge.
5. Don't discard damaged materials until the adjuster has inspected them — keep wet drywall, flooring samples, and damaged belongings for documentation.
6. Track all out-of-pocket expenses — hotel stays if uninhabitable, emergency repairs, temporary storage.

Roof Leak Causing the Water Damage?

If a storm damaged your roof and caused interior water damage, you may have both a roof claim and a water damage claim. See our guide on filing a storm damage roof insurance claim on Long Island and our water damage response guide. Greene Group handles both simultaneously so you're not coordinating two separate contractors.

Basement Flooding — Separate Coverage Issue

Basement flooding from heavy rain entering through window wells or foundation cracks is typically NOT covered by standard homeowners insurance. See our basement flooding guide to understand your options — and consider a water backup endorsement rider on your policy going forward.
