Interlock® Aluminum Roofing — all-climates performance specs for Smithtown, New York
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
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.
I wasted 4 months of my time thinking i will have a beautiful metal roof just to learn that interlock will not be able to do it after all
Interlock Roofing could have improved their communication.
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.
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.
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.
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.
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 Smithtown
The following metal roofing FAQs are designed specifically for homeowners in Smithtown, 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 Smithtown.
Will a metal roof hold up to Smithtown's freeze-thaw cycles?
Yes. Interlock's roofing-grade 3105-H24 aluminum expands and contracts uniformly without cracking or splitting—the material itself is non-porous, so water doesn't penetrate and freeze inside it. Smithtown experiences about 54 freeze-thaw days per year with mean temperatures around 12.4°C; aluminum's homogeneous structure means it won't degrade the way asphalt becomes brittle or wood shakes split under repeated thawing. The four-way interlocking panels lock tighter as they move, not looser. The Guardian warranty explicitly covers splitting and cracking—aluminum simply doesn't do either.
Can aluminum roofing rust in a coastal climate like Suffolk County?
Aluminum cannot rust because it contains no iron—it's physically impossible. Instead, aluminum develops an invisible oxide layer that actually self-heals when scratched, continuously protecting the bare metal beneath. Interlock panels receive Alunar 70% PVDF fluorocarbon coating on both sides, which adds 30-year protection against salt-air corrosion. This dual-side coating is essential near the Atlantic; it's why Interlock roofs perform at Antarctic research stations and on coastal homes nationwide. Even if the coating were removed, the oxide layer keeps working. Steel roofing cannot make this claim—it requires constant vigilance in salt air.
How does a metal roof handle Smithtown's typical 58 cm of snow per year?
Metal roofs shed snow and ice cleanly because their smooth, interlocked surface offers no foothold for accumulation. Smithtown averages about 58 cm of snow annually with gusts reaching 142 km/h; the sloped geometry of profiles like Cedar Shingle or Slate naturally channels melt away, preventing ice dams that form on flat asphalt. The four-way interlocking design eliminates gaps where water can refreeze. Snow guards can be added if desired. Because Interlock panels weigh only 0.41 lb/sq ft for Shingle profile—about 96% lighter than concrete or clay tile—heavy snow loads don't stress your home's structure. No reinforcement needed, even after decades.
Will Interlock metal roofing stay secure in Smithtown's storms?
The four-way interlocking system is engineered to resist wind speeds up to 120 mph (193 km/h) when installed to specification—well beyond Smithtown's typical 21 km/h winds and recorded gusts of 142 km/h. Each panel locks to four neighbors, creating a unified field that moves as one rather than individual shingles peeling away. The warranty covers this explicitly. In a region where coastal systems can spawn powerful gusts, the redundant interlock is far more effective than overlapping or nailed fasteners alone. Insurance companies recognize this durability; contact your agent about potential discounts on a Class 4 impact-rated, 120 mph wind-rated system.
Does an aluminum metal roof protect against hail damage?
Interlock roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Aluminum's malleability absorbs impact energy without cracking; a dent may occur, but the panel remains intact and watertight. Many insurers offer premium discounts for Class 4-rated roofs because the claims history is exceptional. Smithtown experiences occasional severe weather; a roof rated to withstand Class 4 hail offers long-term cost protection beyond what asphalt or composite shingles can match. Speak with your insurance agent before installation—some carriers reduce premiums immediately upon completion.
Can an energy-efficiency metal roof really reduce my cooling costs?
Yes. Interlock offers energy-efficient colors with solar reflectance up to 0.55 (Aged Copper Penny profile) and thermal emissivity of 0.84, meaning the roof reflects rather than absorbs the solar heat that asphalt absorbs. Smithtown averages about 3127 sunshine hours per year; that's significant free cooling potential. Cool Roof Rating Council certification backs these values—no marketing claims. The reflective coating reduces attic temperature and HVAC runtime, lowering summer cooling costs over years of operation. Combined with the 30-year coating warranty against fading, the energy performance remains consistent decade to decade. Savings compound.
What does Interlock's lifetime warranty actually cover?
The Guardian Warranty is a lifetime limited, non-prorated material warranty to the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—defects that plague traditional materials in climates like Smithtown with 1222 mm of annual rainfall and 54 freeze-thaw days. It's transferable once to the next owner, who receives coverage for 50 years from completion. No dollar cap, no degrading coverage schedule. Because aluminum cannot rust and the Alunar coating is warranted 30 years, the material itself lasts the home. This is the last roof you buy. Few warranties in the roofing industry offer such clarity and permanence.
How much maintenance does an aluminum metal roof need?
Minimal. Unlike asphalt shingles that degrade yearly, wood shakes that split in freeze-thaw cycles, or tile that cracks and requires replacement, aluminum panels resist the environmental stressors common to Smithtown—about 1222 mm rain per year, 54 freeze-thaw days, and periodic harsh weather. Alunar PVDF coating (30-year warranty against chalking and fading per ASTM D4214) doesn't require resealing, repainting, or chemical treatment. Occasional debris clearing keeps gutters flowing; that's typical for any roof. Many homeowners report their only maintenance is annual visual inspection. The CALGreen verification confirms reduced maintenance burden compared to traditional materials, saving time and money over decades.
Can you install a metal roof over my existing asphalt shingles?
Yes. Interlock panels are extraordinarily light—Shingle profile at 0.41 lb/sq ft, Shake at 0.58, Tile at 0.59—so most homes don't require structural reinforcement. The weight comparison is striking: the Tile profile is about 96% lighter than concrete or clay tile. This allows installation over existing asphalt without a costly tear-off and landfill disposal. Your local installer, Interlock Roofing of America (serving Smithtown and the region since 2014), can assess your specific roof structure in a site visit. Removing old material is sometimes preferred for inspection or if there's extensive damage; the choice is yours. Either way, the ICC-ES ESR-1790 evaluation report (reissued 2025) confirms code compliance for direct application.
Is aluminum roofing really more recyclable than asphalt shingles?
Yes, fundamentally. Interlock panels are approximately 95% recyclable at end of life; aluminum is endlessly remelted and reused without degradation. Asphalt shingles end up in landfills by the millions of tons annually—old shingles are mixed with tar and granules, making recovery nearly impossible and creating environmental burden for decades. Aluminum breaks that cycle. With a 50-year transferable warranty and lifespans often exceeding 60 years, an Interlock roof reduces your participation in the tear-off-to-landfill pipeline from the start. Over Smithtown's typical annual rainfall of 1222 mm and weather variability, one durable aluminum roof replaces 2–3 asphalt replacements. The environmental math is clear.
