Metal Roofing in Chichester, New Hampshire — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes—aluminum panels shed snow and ice far more effectively than asphalt. Chichester receives about 120 cm of snow annually, and metal's smooth, hard surface prevents snow from bonding and forming dams the way granulated shingles do. The four-way interlocking system keeps panels locked tight even under freeze-thaw stress; you experience roughly 98 freeze-thaw cycles per year here, which cracks and curls asphalt but leaves aluminum unaffected. Optional snow guards let you control shedding for safety if you prefer.

Aluminum expands and contracts uniformly with temperature swings—no cracking, splitting, or curling like asphalt shingles endure. Chichester averages 98 freeze-thaw days annually with winter temperatures dipping well below freezing. Aluminum's oxide layer naturally self-heals when scratched, so surface damage doesn't degrade over time the way wood shake does. The Alunar fluorocarbon finish, warranted 30 years against chalking and fading under ASTM D4214 testing, maintains flexibility and adhesion through thousands of thermal cycles.

Absolutely. The four-way interlocking system is warranted to resist winds up to 120 mph when installed to specification. Chichester's typical gusts reach about 107 km/h (66 mph), well within the roof's rating. Interlocking means each panel locks on all four sides to its neighbors—a single fastener failure won't cause leaks or panel loss. The rigid aluminum construction won't flex or rattle in gusts the way asphalt shingles or cedar shake do, and the system's low weight (roughly 0.41 lb/sq ft for the Shingle profile) minimizes stress on fasteners and framing.

No reinforcement needed. Interlock panels are extraordinarily light—the Mediterranean Tile installs at about 0.59 lb/sq ft, which is roughly 96% lighter than concrete or clay tile. Because of this, Interlock can install over most existing roofs without structural modification. Your home's framing already supports asphalt shingles; metal roofing weighs even less, so the load is actually reduced. This also cuts labor costs and installation time compared to the tear-off required for heavier tile systems. ICC-ES evaluation ESR-1790 confirms the installation method for your region.

Metal roofing is inherently leak-proof when installed correctly. Chichester receives about 1007 mm of rain annually; the four-way interlocking panels overlap and lock tight, shedding water faster than asphalt shingles can. The Standing Seam profile uses vertical seams that channel water downward without pooling. Combined with a solid deck and underlayment, metal roofing provides the same watertight performance as asphalt—without the granule degradation that weakens shingles over time. Proper flashing at valleys, penetrations, and edges (installed by our local team since 1999) completes the system.

Interlock carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers hail perforation up to 1.5 inches. Class 4 means the roof survived repeated impacts from 2-inch steel balls dropped from 20 feet. That durability often qualifies you for insurance discounts; contact your agent with the UL 2218 rating and hail coverage details. Chichester's wind gusts of 107 km/h can carry hail, and asphalt shingles typically rate Class 1 or 2. A Class 4 metal roof reduces your claim risk and may pay for itself in lower premiums over time.

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 transferable once, giving the next owner 50 years from completion. That means your home's roof is covered for your entire ownership, and the next buyer gets half a century more. No asphalt roof comes close. The Alunar coating itself is separately warranted 30 years against chalking and fading. This is the only roof you'll likely buy.

Virtually none. Unlike asphalt shingles, which degrade from UV and thermal cycling, or wood shake, which splits and rots, aluminum doesn't require sealing, staining, or repairs. Chichester's 98 annual freeze-thaw cycles crack and curl asphalt; aluminum stays flat. The Alunar fluorocarbon finish—applied to both sides per a 30-year warranty—sheds dirt and algae in your 1007 mm annual rainfall. Occasional gutter cleaning is all that's needed. No moss treatment, no granule replacement, no emergency repairs. That's sustainability built in: fewer service calls, fewer materials to the landfill, lower lifetime cost of ownership.

Yes—roughly 95% of Interlock panels are recyclable aluminum. At end of life, the aluminum returns to the supply chain for new products, closing the loop. Asphalt shingles, by contrast, end up in landfills by the millions of tons each year; Chichester alone replaces thousands of shingle roofs over two decades. Aluminum never degrades into waste the way organic materials do. Interlock has been manufactured in Delta, BC since 1998 and installed from coastal salt-air homes to an Antarctic research station—proven durability means less frequent replacement, fewer materials harvested and processed, and lower embodied carbon over the roof's lifetime. The waste cycle ends here.

Interlock Metal Roofing (New England) Inc. has served this region since 1999—over 25 years of experience with Chichester's climate, from heavy snow loads of about 120 cm annually to wind gusts reaching 107 km/h. Our local team understands freeze-thaw durability, proper fastening in variable soil conditions, and flashing details that handle New England weather. They're familiar with Chichester building codes and local permitting, and can discuss the current promotion: no payments and no interest until Spring 2027, or 10% off metal roof installation. A local installer means faster response, easier warranty service, and genuine accountability.

Yes. Chichester averages about 117 cm of snow, 1007 mm of rain, roughly 98 freeze–thaw days a year, with peak wind gusts near 107 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.
