Review: June 26, 2014Completion: April 29, 2014

There should always be a person on site that speaks fluent English and communicates with the homeowner before and after the work day.

Review: May 10, 2021Completion: April 27, 2021

The sales process could have been better. We are really happy with the roof. It's outstanding.

★★★★★
Review: March 8, 2021Completion: February 26, 2021

The salesperson did not help the project along. I felt it would have been smoother if I was quoted the right amount, and I was told $13 sq ft, and I was charged $16 sq ft, and they did not put my complete tear off in my contract. It was frustrating as a customer, especially when things were having to be backtracked. I thought employees of interlock were going to do my project, and it was a subcontractor that came to do my installation. I was concerned. It has been 2 weeks and I have asked Jennifer twice now for photos. I have asked how I need to proceed having a contractor do the tuck pointing of my chimney.

The installers could have done a Better job of communicating. The workmanship was not done to my satisfaction, they completed the job leaving my siding in disrepair and had to be called back to fix it. The crew did not clean up all the nails in the yard & driveway. I had to do it. My car got 2 nails in the tires. One employee was sleeping

They could have improved upon the installation crew's language barriers and provided more clarification regarding snow stops. I think that their roofing system is excessively over-priced.

I have already recommended them. They could have had someone to translate/communicate with the crew a little bit better.

Metal Roofing FAQs for Homeowners in New Milford

The following metal roofing FAQs are designed specifically for homeowners in New Milford, Connecticut. 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 New Milford.

Will a metal roof handle Connecticut's freeze-thaw cycles?

Yes—aluminum's oxide layer actually strengthens with temperature swings rather than degrading. New Milford experiences roughly 90 freeze-thaw days per year plus about 87 cm of snow, conditions that crack asphalt and split wood shingles. Aluminum expands and contracts uniformly without fracturing. The four-way interlocking panels accommodate thermal movement while the Alunar® 70% PVDF coating (warranted 30 years against chalking and fading per ASTM D4214) resists salt spray and moisture absorption that would trap ice inside traditional materials.

How does a metal roof perform under New Milford's snow load?

Metal roofing sheds snow more reliably than asphalt because its smooth, slippery surface prevents ice dams from forming in the way organic materials do. With roughly 87 cm of annual snowfall and gusts reaching 119 km/h, the Interlock panels' interlocking seams and lightweight design (the Shake profile weighs only 0.58 lb/sq ft) mean no structural reinforcement is required—the roof carries the load without overloading your framing. Snow guards can be added to manage release on steep pitches if preferred.

Can metal roofing withstand Connecticut wind gusts?

Interlock metal roofing is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—well above New Milford's typical gust extremes of 119 km/h. The four-way interlocking aluminum panels create a unified structural system that distributes uplift forces across the entire roof plane rather than relying on individual fasteners. This design, combined with proper installation per ESR-1790 (the ICC-ES evaluation report reissued 2025), means your roof will remain secure even during the occasional nor'easter.

Will heavy rain cause leaks in a metal roof?

Aluminum cannot rust—it's not ferrous metal. Unlike steel roofing, which corrodes from the inside out when scratched, aluminum develops a self-healing oxide layer. New Milford receives about 1,158 mm of rain annually, but the four-way interlocking seams and factory-applied Alunar® PVDF finish on both sides of every panel (extra protection against moisture) mean water is shed by geometry, not sealant. Properly installed Interlock panels over a solid deck virtually eliminate the leak paths that plague asphalt shingles.

Why don't aluminum roofs rust like steel ones do?

Aluminum contains no iron—rust requires iron oxide to form. The material is instead protected by its own naturally forming oxide layer, which self-heals when scratched, meaning micro-damage doesn't become a corrosion pathway. This matters in New Milford's wet climate (about 1,158 mm annual rainfall, 87 cm snow) where moisture is constant. The Alunar® coating, applied to both panel sides and warranted 30 years against chalking and fading, adds a fluorocarbon barrier that resists salt spray and acidic rain. Steel roofing, by contrast, requires continuous maintenance to prevent rust perforation.

Is a metal tile roof heavy enough to require roof reinforcement?

No—the Interlock Tile profile is about 96% lighter than concrete or clay tile, weighing only 0.59 lb/sq ft, so no structural reinforcement is necessary. Many existing roof frames that cannot support traditional tile can accept Interlock without modification, and the system installs directly over your current roof. This lightweight advantage also means lower labor costs (no tearoff required) and faster installation. Your home's structure isn't penalized for choosing the aesthetic of tile; instead, your framing is relieved of the burden traditional materials impose.

Does a metal roof hold up to hail, and can it lower insurance costs?

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. In New Milford's climate with occasional severe storms, this durability can qualify you for homeowner insurance discounts; contact your agent with the UL 2218 rating to explore savings. Unlike asphalt shingles that dent and lose granules, or clay tiles that crack, aluminum's strength means hail causes cosmetic marking at worst, not structural compromise.

Is metal roofing worth the upfront cost compared to asphalt shingles?

Metal roofing is the last roof you'll buy, while asphalt typically requires replacement every 15–20 years. The Guardian Warranty is a lifetime limited material warranty for the original owner (non-prorated) and transferable for 50 years to the next owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—defects that force premature asphalt replacement. Over a 50-year horizon, you avoid multiple tearoff and landfill cycles. Current promotion: no payments and no interest until Spring 2027, or 10% off installation. That initial investment becomes economical when you never replace it again.

How much maintenance does a metal roof really need?

Minimal—aluminum requires no patching, sealing, or recoating like asphalt or wood shingles. New Milford's roughly 3,074 annual sunshine hours mean your roof is exposed to significant UV, yet the Alunar® 70% PVDF coating (30-year warranty against fading per ASTM D2244) resists degradation. Occasional debris removal and gutter cleaning are your only tasks. Compare this to asphalt shingles, which require roof-mounted sealant reapplication every 5 years, or wood shakes, which split and curl in the freeze-thaw cycle (about 90 days per year locally). Metal outlasts maintenance-intensive alternatives by decades.

Can a metal roof actually reduce cooling costs?

Yes—Interlock's energy-efficient colors feature thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny profile), meaning the roof reflects rather than absorbs the heat that asphalt absorbs and radiates into your attic. With New Milford averaging about 3,074 sunshine hours per year, this reflectance reduces cooling demand in summer. The Cool Roof Rating Council rating confirms the energy benefit. While Connecticut winters are cold, the insulation value is in your attic, not your roof; the reflective benefit applies year-round to reduce thermal load. Combined with the current 10% installation discount, energy savings compound over the roof's 50+ year life.

Is a metal roof a good choice for New Milford’s climate?

Yes. New Milford averages about 87 cm of snow, 1158 mm of rain, roughly 90 freeze–thaw days a year, with peak wind gusts near 119 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.
