  • Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
  • Interlocking aluminum panels tested to 120+ mph (193+ km/h) resist severe gusts and wind-driven snow that impact Hill and other parts of Merrimack County.
  • Designed for Hill’s inland, cold-climate profile — robust panel geometry and secure fastenings manage high snow loads and repeated freeze–thaw cycles.
  • Snow-shedding metal panels reduce buildup on steep roofs, lowering structural stress and helping prevent ice-dam formation during thaw cycles in central New Hampshire.
  • Coated with the Alunar® Coating System (no visible aluminum surface) for durable color retention and superior barrier protection against moisture and de-icing chemicals.
  • Corrosion-resistant aluminum resists deterioration from road salt and de-icing runoff commonly used throughout Hill and Merrimack County.
  • Effective freeze–thaw tolerance prevents cracking, warping, or coating delamination that can affect lower-grade roofing materials in New England winters.
  • Class A fire-rated available to meet higher fire-resistance expectations for properties near open land or during dry, ember-prone periods.
  • UL 2218 Class 4 impact resistance reduces risk from hail, falling limbs, and abrasive ice during seasonal storms.
  • Advanced waterproof installation practices and integrated underlayments provide redundant leak protection for heavy rainfall and rapid spring melts in Hill.
  • Cool-roof properties lower attic heat gain during summer heat waves, improving year-round energy performance for Hill homeowners.
  • Solar-compatible roof platform engineered for bracket-mounted photovoltaic arrays without compromising standing-seam integrity.
  • Low-maintenance, fully recyclable aluminum roofing reduces lifecycle replacement needs compared with asphalt shingles in Hill’s variable climate.
  • Built to shed biological growth: Alunar® surfaces inhibit moss and lichen adhesion common on shaded, moisture-retentive roofs in New Hampshire.
  • Designed to manage extreme precipitation patterns — including atmospheric-river-driven heavy rains that occasionally affect central New Hampshire — by rapidly channeling runoff and preventing intrusion.

Interlock® Aluminum Roofing — all-climates performance specs for Hill, New Hampshire

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

Review: September 30, 2013Completion: August 25, 2013

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.

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.

Better communication and adhering to schedules.

Review: August 18, 2015Completion: July 7, 2015

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.
