- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- Coated with the Alunar® Coating System (no visible aluminum surface) to preserve finish performance and resist chalking in Smithfield’s variable seasons.
- Tested to withstand severe wind loads (193+ km/h / 120+ mph) for exposure to inland windstorms that can impact Smithfield roofs.
- Engineered snow-shedding panels reduce roof snow loads and help prevent ice-dam formation during Somerset County freeze–thaw cycles.
- Class A fire-rated available for added protection during dry, ember-risk periods.
- UL 2218 Class 4 impact resistance for protection against hail, falling branches, and storm debris common to New England weather.
- Low thermal emittance and cool-roof performance lower attic heat gain during occasional Maine summer heat waves, improving year‑round comfort in Smithfield homes.
- Solar-compatible roof plane and attachment details support modern bracket-mounted photovoltaic systems without compromising weatherproofing.
- Fully recyclable aluminum substrate supports long-term sustainability goals for Maine homeowners and municipal waste reduction.
- Architectural profiles replicate slate, cedar shake, and tile to match traditional Smithfield rooflines while using proven metal performance.
- Low-maintenance finish minimizes routine care needs in Smithfield’s moisture-prone seasons, extending service life versus conventional shingles.
- Lifetime-limited transferable warranty documents performance expectations and helps protect property value for Smithfield homeowners.
- Designed to manage intense, prolonged rain events and nor’easter-driven precipitation — including atmospheric-river episodes that can deliver concentrated rainfall to central Maine.
- Although inland Smithfield experiences minimal marine salt exposure, the Alunar®-coated aluminum and corrosion-resistant fasteners provide robust resistance where road salts or occasional coastal spray affect nearby properties.
- Factory-coated surfaces combined with rapid snow-shedding reduce persistent dampness on shaded roofs, limiting conditions that promote moss and organic growth.

Interlock® Aluminum Roofing — all-climates performance specs for Smithfield, Maine
| 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:
Bought this roofing 20 years ago. It was installed well. Needed improvements to my roof structure were suggested and made to ensure the longevity and worthiness of my roof. All these years later I am still happy I made the investment in my 160 year old home.
Communication to one person. More workers speaking English would be helpful Should really offer gutters as part of roof installation
I do not think they fell short. They all worked very well.
