Welcome to


You’ll notice something different about A1 Roofing the moment we walk in the door: our boots. You won’t see them because they’re covered by surgical booties.  Why? Because we go to extraordinary lengths to protect your property. We break the traditional mold (roofing and siding is typically messy in both presentation and process) to deliver a superior level of cleanliness and professionalism driven by intense attention to detail. It’s the foundation of our family owned business and the result is pristine quality – above…and beyond.

What our clients say


“A-1 did a great job. They cleaned up nicely and the roof was done just like they said it would be. I could not be any happier and I will be using them again.”

D. PeabodyE. Patchogue,

“John from A-1 Roofing arrived for an estimate exactly on time. He was very friendly, professional, and totally honest – and gave us a very reasonable and compatible estimate. He arrived at 7:15 a.m. (as planned) with a full crew and equipment and was totally cleaned up and done by 11:30 a.m. It was like they were never even here. I would highly recommend A-1. John and his crew deserve an A+ across the board.”

M. DabrowskiNesconset, NY

“I can’t say enough good things about A1 Roofing. The crew replaced my old roof – and installed sheathing, rafters, gutters, and leaders all by 4pm. (These guys are super!) The grounds were spotless after the job. The crew could not have been nicer. And the price was more than fair. They arrived at 7am, set up quickly and went to work like a roofing machine. I’ll be sure to call them again when I have my siding done.”

R. ReynoldsPort Jefferson St., NY

“I needed my gutters cleaned and gutter screens installed. A-1 Roofing was great. The crew called me back in a timely manner and did the job quickly, neatly, and efficiently. I always worry about finding good professional work with small jobs, so I was pleasantly surprised. The price was very reasonable, too. What we thought would cost about $600 only costed us $400. A great company!”

E. EverettSound Beach, NY

“It went great. A-1 Roofing was the most responsive and knowledgeable company, and the crew came out quickly to do an estimate (even in the middle of tons of snow!) The crew scheduled the job around us, and we were very happy with this company. We definitely plan on using them again in the future.”

J. Ripton-SnyderStony Brook, NY

“I had a severe leak in a flat roof and in the siding surrounding it. The crew came and replaced the flat roof and some of the cedar siding. They were fast, efficient, and cleaned everything up. The entire job took 3 hours. Excellent – from estimate to completion was less than one week.”

V. SchwartzWesthampton, NY

“A-1 Roofing was great. The crew arrived when they said they would, gave me a compatible estimate, and told me what to expect from the job. A-1 started when they said, even earlier, knowing the importance of completing the work before another rain storm. The crew was prompt, clean, and professional, and did a better job than what was discussed for the estimate. I couldn’t be happier with the job and company. Would use them again!”

E. St. MarieManorville, NY


We’re glad to answer our top frequently asked questions.

How much will the job cost?

Every job varies in cost depending on many factors such as the square footage, number of roof and siding layers, and pitch of the roof.

How long will the job take?

Most residential roofing jobs are completed in 1 day, siding jobs 5-10 days depending on the size and scope of the project. Commercial roofing projects also vary based on size and scope.

Do you use dumpsters?

No, we have our own dump trucks that cart all debris away.

What do we need to do to prepare for the job?

Be sure that the driveway is clear of any cars. If you have any valuables on the walls you may want to take them down.

If I experience a leak within a few years of the installation of the roof do you come back?

Yes, we offer a twelve year labor warranty on all new work completed. We offer extended warranties at an additional cost.

Are you licensed and insured?

Yes, we are licensed in Nassau and Suffolk County for roofing and siding work. A copy of our insurance certificate is provided in our folder that every customer receives at the time of the estimate.
