Interlock® Aluminum Roofing — all-climates performance specs for Danbury, New Hampshire
| 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:
The original schedule was not communicated or held to very well. I did not want the roof put on after it snowed in Nov. which was 8 weeks after the contract was signed. Consequently it took until July to finally get a jointly agreed upon installation.
Roof removal was not always cautious but the team responded to commentary and improved.
They do excellent work.
Improve scheduling accuracy, show up when they said they were going to: original phone call stated work to begin on a Saturday, deliver products Wednesday prior to that Saturday. Work did not begin until the following Tuesday.After the work was completed, still picking up nails and snips of materials on the ground.Also, 4/5 rows on the mud room roof were redone by customer request for misalignment/crooked rows. The wooden shingles on the main part of the house joining the mud room were roughly cut, to install the flashing; did not look like a professionally cut. We opted to redo the shingles ourselves to our standards.We expected the quality of the workmanship to reflect a higher level of professionalism; still waiting to evaluate the product. How will it perform in all seasons, mostly the way it should shed the snow! Would NOT do this again!
I never had a roof replaced before, but I am very happy with it. They did an excellent job.
I have passed along Dave Harrison's card. Would warn about possible time frame issues and the mess. Also I would liked to have seen a more clearly written contract (what's with the exclamation points, Dave?) but as a retired real estate broker maybe I'm being too picky. Apparently the roofer couldn't understand it either (or didn't read it) when I had to show him where it indicted "no ridge vent on the main house" which he was about to do. Communication as to the start date of our project and knowing when the workers were going to be here so we could plan our day. They would miss work here on beautiful days and then arrive at 11:45 a.m. on a Sunday morning. Not working on a rainy day is expected but it would have been nice if they (and not me) had picked up the tools that were left scattered around the lawn. Not getting a timely response to our ridge vent problem is an ongoing worry. It has been over a month since I contacted Dave Harrison and still we have had no word from Interlock. This project was a nightmare but we do like the look of the product and only hope that it was well installed. I had asked Dave Harrison for an estimate on another of our homes next door to my sister's re-roofing project on Gould Road, Warner. He never got back to me. I'm not sure my blood pressure could stand this again anyway.
Our first Interlock roofing project was a great success which led us to use them again. Unfortunately, the second project did not go as smoothly and we are definitely not as pleased with the process this time.
We chose Interlock to install a much needed new roof on our 200-year-old farmhouse in Warner, New Hampshire which serves as our year-round vacation getaway. From the moment David showed up to meet with us through the final completion of the project a few weeks ago, we knew that we had made the right decision and that our project was in good hands. We never once felt pressured even though we took longer than expected to complete some preliminary repairs to a porch roof before the project could begin. When we did finally call to say that we had completed our work and were ready to go, they had a work crew on site in less than a week! More amazing is that they completed their work of stripping the old asphalt, installing a plywood deck, and re-roofing a large old house where nothing is truly square in five days and, other than the evidence of a brand new gray slate roof on our house, one would never know that anyone had even been there. The crew left our property cleaner than it was before they arrived. They even cleaned up a pile of roofing debris we had left behind following our re-roofing project. Throughout the project, David and Jennifer, in the office, were always available to answer our questions. From selecting the right roof to arranging to finance, to completing the project in a timely fashion, we could not be happier with the total interlock experience. We are highly satisfied with the result and are already looking forward to having Interlock install a new roof on our adjoining barn in the near future.
Better communication and adhering to schedules.

Metal Roofing FAQs for Homeowners in Danbury
The following metal roofing FAQs are designed specifically for homeowners in Danbury, New Hampshire. 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 Danbury.
Does metal roofing handle heavy snow loads in Danbury winters?
Yes — Interlock's four-way interlocking panels are engineered to shed snow safely while the aluminum's extraordinary light weight (the Slate profile at just 0.41 lb/sq ft) means no structural reinforcement is needed, even under Danbury's average 166 cm of annual snowfall. The interlock design resists snow creep and ice dam formation better than asphalt, which absorbs moisture during the region's roughly 93 freeze-thaw cycles per year and degrades faster. Snow guards are available if you want to control roof runoff in specific areas.
How does aluminum roofing survive New Hampshire's freeze-thaw cycling?
Aluminum is naturally immune to freeze-thaw damage because it contains no iron and cannot rust or rot — the oxide layer that forms on its surface actually self-heals when scratched, so moisture infiltration never triggers the expansion and contraction that destroys asphalt and wood over Danbury's 93 annual freeze-thaw days. The Alunar 70% PVDF coating (applied to both sides) adds 30 years of fade and chalk resistance even as temperatures swing. Metal roofing simply does not degrade from water absorption like traditional materials do.
Can a metal roof withstand Danbury's wind gusts?
Absolutely. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification — well beyond the typical 116 km/h gusts Danbury experiences. The four-way interlocking design means each panel locks on all four sides, creating a unified structure that distributes wind load across the entire roof rather than failing at fastener points. The ICC-ES ESR-1790 evaluation confirms this performance under IBC/IRC codes, so your roof stays secure through nor'easters and weather extremes.
Does hail damage metal roofing, and could this lower my insurance?
Interlock aluminum carries a UL 2218 Class 4 impact rating — the highest available — and the warranty covers perforation from hailstones up to 1.5 inches. This extreme durability often qualifies homeowners for insurance discounts because metal roofs rarely file claims; contact your insurer with the UL rating and ICC-ES report (ESR-1790) to explore savings. Danbury's climate brings occasional hail, and unlike asphalt (which splits and cracks from impact), aluminum's non-brittle nature absorbs the blow and bounces back.
Why won't my aluminum roof rust like steel or corrode over time?
Aluminum contains no iron — the element that rusts — so rust is physically impossible. Instead, a microscopic oxide layer forms naturally on the surface and self-heals when scratched or abraded, creating permanent corrosion protection without maintenance. The Alunar 70% PVDF fluorocarbon finish (applied to both sides of every panel) then adds a second line of defense warranted 30 years against fading and chalking per ASTM D4214/D2244 standards. In Danbury's 847 mm of annual rain and freeze-thaw extremes, this dual protection means your roof won't degrade from moisture, salt air, or chemical exposure.
Do I need to reinforce my roof framing for a metal roof?
No — and that's one of aluminum's greatest practical advantages. The Interlock Mediterranean Tile profile, for example, weighs only about 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile, so it installs directly over most existing roofs without structural work. This means lower labor costs, faster installation, and the ability to overlay your current roof rather than tear it off. Even under Danbury's 166 cm average annual snowfall, the light weight eliminates the expensive rafter upgrades that traditional materials demand.
Will a metal roof help lower cooling costs in summer?
Yes. energy-efficient Interlock colors achieve thermal emissivity up to 0.84 and initial solar reflectance as high as 0.55 (Aged Copper Penny), meaning they reflect heat that asphalt absorbs and re-radiates into your home. Across Danbury's roughly 2,958 annual sunshine hours, this reflectivity compounds, reducing air-conditioning demand without sacrificing the roof's aesthetic. The Cool Roof Rating Council rating backs this performance. You won't notice savings in winter (when you want solar gain), but summer cooling loads drop measurably.
What's the real warranty on an Interlock metal roof, and does it transfer?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner — covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's fully transferable once: the second owner receives 50 years of coverage from completion. This is the only roof you'll likely install, meaning no mid-life tear-off and replacement costs. Combined with aluminum's inherent resistance to freeze-thaw cycles and Danbury's 93 annual cycles, this warranty protects your family's investment across decades.
How much maintenance does a metal roof really need?
Metal roofing requires far less maintenance than asphalt, wood, or tile. Unlike asphalt (which degrades under Danbury's 93 annual freeze-thaw cycles and 166 cm snowfall), aluminum doesn't split, curl, or absorb water. No moss treatment, no tar-and-gravel upkeep, no seasonal inspections for damage. Simply rinse debris after storms or annually; that's it. The Alunar 70% PVDF coating resists chalking and fading for 30 years (ASTM D4214), so your roof stays vibrant without sealant reapplication. CALGreen verification confirms reduced maintenance versus traditional materials.
Is metal roofing better for the environment than asphalt shingles?
Yes, substantially. Interlock aluminum is approximately 95% recyclable, and at end-of-life (decades away), it returns to the recycling stream rather than a landfill. Asphalt shingles, torn off and replaced every 15–20 years, immediately become landfill waste. Over a 50-year period, a traditional roof generates multiple tear-offs; Interlock ends that cycle with one installation. Danbury's roughly 847 mm annual rainfall and heavy snowfall accelerate asphalt degradation, meaning more frequent replacements and more waste. Metal roofing—installed once and passed on—is the environmentally responsible choice.
Is a metal roof a good choice for Danbury’s climate?
Yes. Danbury averages about 166 cm of snow, 847 mm of rain, roughly 93 freeze–thaw days a year, with peak wind gusts near 116 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
