Choosing a roofing contractor in NYC

Roofing is a trust purchase. You cannot inspect the work from the ground, and the worst outcomes surface years later. The vetting below is boring on purpose. Boring is what protection looks like.

The license check comes first

In New York City, home improvement contractors working on residences must hold a Home Improvement Contractor license from the Department of Consumer and Worker Protection. The license number should appear on the contract, the vehicle, and any advertising. Verify it on the city's license lookup before the first meeting ends. If a job involves structural work or most full replacements, expect Department of Buildings filings as well, handled by the contractor.

Homeowners near the Outerbridge and Goethals crossings often collect bids from New Jersey companies too. New Jersey has its own home improvement contractor registration through the state Division of Consumer Affairs. A New Jersey registration is not an NYC license. A contractor working a Staten Island address needs the NYC credential, wherever the office sits.

Insurance, in writing, from the insurer

Ask for certificates of general liability and workers' compensation naming you as certificate holder, sent directly from the insurance agent. A photocopied certificate handed over in person proves what was true once. Roofing is exactly the trade where an uninsured injury on your property becomes your problem.

What a real contract contains

• The license number, business address, and a named point of contact.
• An itemized scope: tear-off layers included, underlayment products, flashing to be replaced, ventilation work, decking unit price.
• Start window, duration, and how weather delays are handled.
• Payment schedule tied to milestones. New York's home improvement rules restrict deposits and require contract terms in writing. A demand for most of the money up front is a legal problem, not a negotiating quirk.
• Debris, dumpster, and property protection terms, including where the container sits.
• Workmanship warranty in years, separate from manufacturer shingle terms, and what voids it.
• Change order procedure with prices agreed in writing before extra work proceeds.

Red flags that end the conversation

• No license number, or a number that fails the lookup.
• A price that requires signing today.
• Cash-only, or a deposit far beyond what state rules allow.
• An offer to cover or waive your insurance deductible.
• No physical business address, or a truck with out-of-state plates the week after a storm.
• Vague scope lines like "repair as needed" with no unit prices.

Comparing three bids well

Get three itemized bids and normalize them before comparing totals. Confirm each includes the same tear-off count, the same underlayment class, the same flashing replacement, and the same ventilation plan. The cheapest number usually differs in what it omits. When one bid is far below the others, the missing money is somewhere in the scope, and it will find you at change-order time.
