- Authorized Interlock® installer serving South Harbor homeowners in Mille Lacs County
- Designed for South Harbor’s inland climate, handling heavy snow loads, freeze–thaw cycles, and wide seasonal temperature swings
- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
- High snow-shedding panels reduce roof accumulation and lower ice-dam risk on lake-area and rural roofs around South Harbor
- Durable aluminum substrate coated with the Alunar® Coating System (no visible aluminum surface) for extended finish life and corrosion resistance
- Tested to withstand severe wind events applicable to central Minnesota storm gusts and localized windstorms
- UL 2218 Class 4 impact resistance for protection from hail, fallen limbs, and storm debris common in the region
- Class A fire-rated available to address ember and wildfire-risk considerations during dry periods in Mille Lacs County
- Cool-roof reflective performance reduces summer heat gain and improves attic comfort for South Harbor residences
- Solar-compatible roof profiles accept modern bracket-mounted photovoltaic systems without compromising weatherproofing
- Fully recyclable aluminum construction and low-maintenance finish reduce lifecycle waste compared with shingle replacement
- Architectural profiles replicate slate, cedar shake, and tile; standing seam option provides mechanically fastened retention and clean sightlines
- Backed by a Lifetime-Limited transferable warranty to protect investment and resale value for South Harbor properties
- While true Pacific-style atmospheric rivers are rare in inland Minnesota, the system’s precision seams and robust flashings still provide reliable protection during occasional intense rain events
- South Harbor sits inland on Mille Lacs Lake—marine salt-air corrosion is not a primary concern, though the Alunar® coating adds extra corrosion resistance for lakeside exposures
- High-moisture lakeshore microclimates near South Harbor can encourage moss and lichen; smooth Alunar® finishes and steep-shedding panels minimize biological buildup and simplify maintenance

Interlock® Aluminum Roofing — all-climates performance specs for South Harbor, Minnesota
| 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. |
