- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- Aluminum is coated with the Alunar® Coating System (no visible aluminum surface), providing corrosion resistance against de‑icing salts and seasonal lake spray in Saint Lawrence and Washington County.
- Designed to shed heavy Wisconsin snow loads and tolerate repeated freeze–thaw cycles typical of Saint Lawrence winters.
- Snow-shedding panel geometry reduces rooftop accumulation and helps prevent ice-dam formation on Saint Lawrence homes.
- Interlocking panels tested to 193+ km/h (120+ mph) for severe windstorms, enhancing wind resilience for properties across Saint Lawrence and nearby Washington County.
- Mechanical standing-seam fastening reduces uplift and perimeter failure during regional gust events and blizzard-driven winds.
- Class A fire-rated available to provide ember resistance and meet local code requirements during dry seasonal periods.
- UL 2218 Class 4 impact resistance protects against hail, falling branches, and winter storm debris common in Washington County.
- Rigid aluminum panels limit fatigue from wide temperature swings, reducing seam stress from freeze–thaw cycling in Saint Lawrence.
- Cool-roof characteristics lower attic temperatures during occasional summer heat waves, improving HVAC efficiency for Saint Lawrence residences.
- Solar-compatible for modern bracket-mounted photovoltaic systems, simplifying PV installation on houses in Saint Lawrence.
- Low-maintenance, fully recyclable aluminum reduces long‑term replacement and disposal costs for Washington County homeowners.
- Moss: the smooth Alunar finish inhibits moss, lichen, and organic growth on shaded, moisture-prone roofs in Saint Lawrence.
- Atmospheric rivers: while primarily a coastal term, the system’s continuous seams and drainage capacity are engineered to handle intense rainbursts and rapid snowmelt runoff events that affect Saint Lawrence.
- Coastal salt air: not a local exposure for inland Saint Lawrence, yet the Alunar-coated surface still defends against corrosion from road salts and occasional lake spray.

Interlock® Aluminum Roofing — all-climates performance specs for Saint Lawrence, Wisconsin
| 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. |
