How We Selected These Companies
Every company on this list was evaluated on the following criteria:
- Google rating and review volume (both the score and the number of reviews matter)
- Years in business (longevity reflects reliability and proven skill)
- Range of services (versatility is a real advantage for homeowners)

- Local presence (companies rooted in the Long Island community)
What to Ask Before Hiring a Roofer on Long Island
Before you sign anything, here are a few questions worth asking any roofing company you are considering.
Are you licensed and insured in New York State? This is not optional. Any contractor working on your home in NY needs to carry liability insurance and workers’ compensation coverage. If something goes wrong without proper coverage, you could end up holding the bill.
Do you use your own employees or subcontractors? Several companies on this list specifically use in-house crews only. That typically means more consistent quality and real accountability on every job.
What warranties do you offer on labor and materials? Material warranties come from the manufacturer, but labor warranties come from the contractor. A company that backs their own workmanship is telling you something about the confidence they have in what they do.
Can you help with my insurance claim? If your roof was storm-damaged, your homeowner’s insurance may cover a significant portion of the repair or replacement. Some companies on this list specialize in handling this process for you at no extra cost.
How long have you been doing this locally? Long Island’s coastal climate, salt air, and Northeast weather patterns are specific. Roofers with decades of local experience have seen and dealt with problems that newer contractors simply have not encountered yet.
Frequently Asked Questions
How much does a roof replacement cost on Long Island? Costs vary based on roof size, pitch, material choice, and whether any structural repairs are needed. Most homeowners on Long Island can expect to pay somewhere between $8,000 and $20,000 for a full asphalt shingle replacement on a typical single-family home. Getting two or three quotes before committing is always the smart move.
How often should I have my roof inspected? Most roofing professionals recommend at least once a year, ideally in spring after winter weather, and again in the fall before storm season arrives. If your roof is over 15 years old or you have been through a major weather event, do not wait for the annual schedule.
What is the most popular roofing material on Long Island? Asphalt shingles are by far the most common choice for Long Island homes. They offer a solid balance of durability, affordability, and style variety. Architectural or dimensional shingles have largely replaced traditional 3-tab shingles as the go-to option because they last longer and look significantly better.
Can I stay in my home during a roof replacement? Yes, in most cases. A professional crew can typically complete a standard residential roof replacement in one to two days. It will be noisy, so plan for that, but you do not need to move out.
How do I know if I need a repair or a full replacement? If your roof is under 15 years old and the damage is limited to a specific area, a repair usually makes sense. If it is older, or if more than roughly a third of the surface is compromised, a full replacement is almost always the more cost-effective long-term call. Any company on this list will give you a free and honest assessment.
Final Thoughts
Long Island has no shortage of roofing contractors, but the five companies on this list have built their reputations through years of consistent, high-quality work and genuinely satisfied homeowners. Whether you are dealing with an urgent leak, planning a full roof replacement, or just getting a preventive inspection done before storm season, any of these contractors is a solid place to start.
Get at least two or three quotes, ask the right questions, and do not let price alone drive your decision. A roof is a long-term investment in your home, and the few hundred dollars you might save going with the cheapest option rarely outweighs the cost of poor workmanship down the road.
This list reflects publicly available information and customer reviews as of 2026. Always verify current licensing and insurance directly with any contractor before hiring.
