  • Corrosion-proof aluminum construction resists salt-laden air transported inland from nearby York County shorelines during onshore storms
  • Tested to withstand severe wind conditions up to 120+ mph (193+ km/h) to protect Cornish roofs from gusts and storm surges associated with coastal storms
  • Snow-shedding panel geometry and low-friction finish reduce heavy-snow accumulation and lower the risk of structural overload on Cornish homes

  • Atmospheric rivers and intense downpours: reinforced seams and elevated flashings protect against rapid runoff and prolonged wet periods in the Cornish area
  • Coastal salt air: protective coatings and non-ferrous fasteners prevent corrosion when marine aerosols reach inland Cornish neighborhoods during strong onshore winds
  • Moss control: finish chemistry and panel slope minimize moss and organic buildup on shaded, moisture-prone roofs common in Cornwall’s wooded lots
  • Fully recyclable aluminum construction and long service life support sustainable choices for homeowners throughout York County, backed by a transferable lifetime-limited warranty

Interlock® Aluminum Roofing — all-climates performance specs for Cornish, Maine

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: August 23, 2021Completion: July 28, 2021

We had a little problem with our lawn. The people that Interlock Roofing hired or subcontracted, removed the asbestos and ground it up pretty bad. It's all over the yard. They have not gotten back to me and I'm pretty ticked off about that. Interlock Roofing could have improved by responding to me about the problems with the lawn. They said it would look like they were never here once they left. The asbestos guys used a lift and I have stuff all over the lawn. It's in my neighbor's lawn too. If Interlock Roofing says they are going to leave the yard as it was before they got here, they should do that. They should do what they say. I'm really disappointed in that. The roof is wonderful. We love the roof.
