Review: June 10, 2016 Completion: March 1, 2016

I am very disgusted with what happen in terms of what the salesperson told me I was going to get. My neighbor has the same roof and said that he had a good job Interlock was over sold and under delivered in terms of what they promised. I think they could have improved on customer service, follow up, letting the customer know when the start dates change, and the installers should be more prideful in their work. I called back several times about when they were going to start the work. I was told by the contractor that my problems would be forward to the office but no one in the office knew about my problems. I know foresee that I will have issues down the road because it was not put on properly. I think they should do it right the first time and do exactly what they say they will do. Some of my concerns and issues are based on what I have gone through. I don't want anyone else to go through this. I feel that there might be some customers who don't speak up and will just let things slide by and that isn't right. The owner doesn't know what the people are costing his company by the lack of workmanship and quality of work and customer service. When people get this kind of service they will never use that company again. I told Jennifer that they gave me a Mercedes roof but had installers for Ikea install it. My neighbor feels bad for recommending them to me.I work at home and I am most of the time. The last day they completed the job no one told me that it was going to be the last day. I was two hours away when I got the call that it was the last day and they were done and I needed to sign paperwork. He wanted me to walk around the property to look at the work but by the time I got home the sun had already set and I couldn't see anything. I refused to sign off on the work.

Review: December 13, 2014

I would love to do it, but I can't justify spending that much money. I love the product, but I'd have to win some money to afford it. I like the sales pitch, and the salesman, but it cost too much. They have a unique product, and the design is good.

Review: December 26, 2009

We are writing to thank your company for the wonderful new roof installation that we have. It is refreshing in today's business world to be able to have a company say and do exactly what is expected of them. Your sales representative, Robert Allen, was very knowledgeable and informative about the product and the installation of it. He was not an aggressive salesman, which we appreciated. The installers were the BEST! Dmitry, Leonid and Danny were the hardest working men we have ever had work on anything that we have ever had done at our house. They worked every moment that they were here, and the most severe conditions. The job was finished in a timely manor. We definitely will recommend your company to our friends.

Review: April 20, 2009

I’m not sure who to best direct this letter of appreciation to but I’m assuming it will be shared with Interlock officials. As briefly mentioned in an email to you we are thrilled with everything. From our initial deliberations in choosing Interlock to the completion of the project we have been impressed. We have completed many remodeling projects in our home. Replacing a roof certainly would be considered major. To know that we will not need to worry about replacing it is very comforting, not to mention the impressive appearance and worth it has added to our home and neighborhood. We would be remiss if we didn’t mention the extraordinary work and work habits of Nazar. Committed, exacting, attention to detail, particular are words that immediately come to mind. His knowledge and work ethic are off the scale – long work days, mindful of what needs doing next (particularly with vagaries of spring weather) are noteworthy. He’s a gem you can absolutely depend on. We await our first major nasty weather event to put this all to test – one that we were very confident about. Thank you once again. It is reassuring to know we will benefit so nicely from the superior workmanship and quality of the roofing products.

Review: September 28, 2008

My wife and I wanted you to know that we are very pleased with the new Interlock shingle roof recently installed on our twenty year old home. The color matches the rest of our home and the shingles look tremendous. While we knew we needed a new roof and we we looked at a number of different options and contractors, we believed that selecting your company was without a doubt a winner in every respect. We became aware of your product through the website of the ">Metal Roofing Alliance that led us to your company's own web page. Subsequently, we met with Mr. Robert Allen, Regional Marketing Coordinator of New York's Best Roof, Inc., who fully addressed all of our questions and was readily available throughout the process. Installation was also handled in a very professional manner, and we could not ask for better assistance from either Mr. Allen or the installation crew of New York's Best Roof, Inc. We look forward to many happy years under the security of our new aluminum shingle roof, and would gladly recommend your product and the team from New York's Best Roof, Inc. to anyone. We are also very pleased with the energy savings, maintenance free characteristics and environmentally friendly aspects of our new ">aluminum roof.

Review: July 21, 2008

To: Interlock / New York's Best Roof My husband and I wanted to write to you to let you know how pleased we are with our entire experience working with Interlock. We now have a beautiful new roof and the process was totally professional and first rate. We first learned about Interlock from information received in the mail. However Mr. Robert Allen, our sales coordinator, gave a very thorough, knowledgeable presentation of the roofing product, answering our questions, showing samples and leaving us with written materials we could look over at our leisure. Mr. Allen was always a phone call away to answer our questions, returning our calls if not the same day certainly with a 24-hour period. Once we decided to purchase an Interlock roof, the time frame spelled out in the contract was adhered to. Financing was available and Mr. Patrick Doyle worked very diligently to get us the best rate of interest available to us. Whatever concerns we had were addressed and the paperwork was simple and straightforward. The installment crew was professional, courteous and hardworking. Our roof was done in 2 1/2 days and clean-up was always done at the end of each day. The crew always spoke with my husband in a polite, unobtrusive manner and did whatever it took to make the installation as easy as possible. Now not only do we have a great looking roof with a 50-year " title="warranty" data-wpil-keyword-link="linked">warranty, we also bought a great product. The roofing itself creates minimal waste and is recyclable. It reflects the sun in the summer so our air conditioning works more efficiently. In the winter we no longer have to snow rake the roof, the snow melts off automatically. Our house now seems quieter, even our 14 year old son remarked he didn't know it was raining until the rain hit the windows. Our new roof gives our house a more finished look and according to our tax expert, ">metal roofs are tax-deductible! My husband and I can not only say enough positive things about interlock. We would highly recommend their product and company to anyone considering a new roof. Drive by and see the finished product!

Metal Roofing FAQs for Homeowners in Mount Sinai

The following metal roofing FAQs are designed specifically for homeowners in Mount Sinai, New York. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Mount Sinai.

Will a metal roof hold up through Mount Sinai's freeze-thaw cycles?

Yes — aluminum's oxide layer actually strengthens with temperature swings rather than degrading. Mount Sinai experiences roughly 54 freeze-thaw days per year, a condition that cracks asphalt and causes wood to split and curl. Interlock's roofing-grade 3105-H24 aluminum alloy (ASTM B209) expands and contracts uniformly without brittleness or fatigue. The four-way interlocking panels also accommodate movement without stress concentration, so the roof adapts to seasonal strain that destroys conventional materials over time.

How does metal roofing handle the snow loads in Suffolk County?

Mount Sinai receives about 58 centimeters of snow annually, but aluminum's extreme light weight means the structural load is negligible. A Slate profile panel weighs only 0.41 lb/sq ft—about 96% lighter than traditional clay or concrete tile—so heavy snow sits on your roof without risk of sagging or requiring expensive reinforcement. The smooth, low-friction surface actually sheds ice and snow more readily than asphalt, reducing ice dam formation when paired with proper ventilation and snow guards where local code requires them.

Does Interlock's metal roof leak in Mount Sinai's heavy rain?

No. Mount Sinai receives about 1,222 millimeters of rain yearly, yet the four-way interlocking aluminum panels are engineered to channel water downward with zero overlap gaps where moisture can penetrate. Each panel locks on four edges, creating a continuous weather barrier. When installed over solid decking and 30-lb felt underlayment to spec, the system sheds rain as effectively as asphalt while eliminating the granule loss and membrane breakdown that shortens shingle life in wet climates. Proper flashing at penetrations is the only installation detail that matters.

Will my metal roof withstand Mount Sinai's coastal wind gusts?

Yes — the warranty covers wind speeds up to 120 mph (193 km/h), well above Suffolk County's typical gust speeds of 142 km/h. The four-way interlocking system locks each panel on all four edges, distributing wind load across the entire roof plane rather than concentrating stress on fasteners or seams. This engineering is why Interlock panels have been installed at Antarctic research stations and coastal salt-air homes worldwide. Local gusts may exceed 100 km/h seasonally, but the interlocking design has proven itself in more severe marine environments.

Why won't an aluminum roof rust like steel roofing can?

Aluminum cannot rust because it contains no iron — the element that oxidizes and corrodes. Instead, aluminum develops a microscopic oxide layer that forms automatically when exposed to air and actually self-heals when scratched. Interlock adds Alunar® 70% PVDF fluorocarbon coating on both sides of every panel (not just the top), providing extra protection in Mount Sinai's salt-influenced coastal air. This dual-side coating carries a 30-year warranty against chalking and fading. Steel roofs corrode from the inside out; aluminum roofs simply age in place without structural decay.

What hail protection does Interlock offer, and can it lower my insurance?

Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Suffolk County's hail risk is moderate, but the Class 4 rating means your roof absorbs impacts that would puncture or dent asphalt or conventional metal. This third-party certification (UL 2218 is the insurance industry standard) often qualifies homeowners for impact-resistant discounts from insurers. Contact your agent with the UL rating to explore potential savings; many carriers recognize the durability advantage.

Will an energy-efficiency metal roof reduce cooling costs in summer?

Interlock's energy-efficient colors reflect up to 55% of solar energy (tested by Cool Roof Rating Council) with thermal emissivity of 0.84, compared to asphalt's near-zero reflectance. Mount Sinai receives about 3,127 sunshine hours annually, meaning a reflective metal roof continuously redirects summer heat instead of absorbing it like dark shingles. This reduces air conditioning load, particularly over unvented attics. The energy benefit compounds year after year; over a 50-year roof life, the cooling savings often offset a significant portion of the material cost while lowering your household's peak-demand carbon footprint.

Is Interlock metal roofing worth the upfront cost versus asphalt?

Over a roof's full lifespan, metal is the lower-cost choice. An asphalt roof lasts 15–20 years and requires tear-off, landfill fees, and replacement labor twice in the time one Interlock roof performs. The Guardian warranty is non-prorated for the original owner and one-time transferable to the next owner for 50 years from completion—meaning if you sell, the buyer gets 50 years of material coverage. Factoring in re-roofing labor, disposal, and energy savings from energy-efficiency reflectance, aluminum's higher upfront cost becomes the last roof you'll buy, making it the most economical long-term investment.

How much maintenance does a metal roof need compared to asphalt or tile?

Virtually none. Unlike asphalt shingles (which require annual inspection, moss treatment, and eventual replacement of deteriorated sections), Interlock aluminum is CALGreen-verified for reduced maintenance. It doesn't split, curl, crack, or lose granules—the primary failure modes of asphalt in Mount Sinai's 1,222 mm annual rainfall and 54 freeze-thaw cycles. Tile requires recaulking and underlayment replacement; aluminum panels don't. Periodic gutter cleaning and debris removal are all that's needed. The coating carries a 30-year warranty against chalking, so color retention is guaranteed, not assumed.

Does Interlock have a local installer serving Mount Sinai?

Yes. Interlock Roofing of America has served Suffolk County since 2014 and maintains direct familiarity with Mount Sinai's climate, building codes, and installation best practices for freeze-thaw durability and salt-air environments. The local team understands that proper underlayment, flashing, and ventilation are critical in a region that sees 58 centimeters of snow and frequent wind gusts near 100 km/h. Working with an experienced local installer who knows the ICC-ES ESR-1790 code compliance pathway (reissued 2025) ensures your roof is engineered correctly for Suffolk County conditions from day one.
