Metal Roofing Built for Thatcher's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection

Performance you can measure (all climates):
⢠Aluminum is Coated with the Alunar® Coating System (no visible aluminum surface) to resist coastal corrosion and preserve finish on Thatcher roofs
⢠Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
⢠Corrosion-resistant alloy and coating formulated for prolonged salt air and marine exposure around Thatcher and nearby San Juan County shorelines
⢠Tested to 193+ km/h (120+ mph) to withstand severe storm winds and gusts common in the San Juan Islands
⢠Advanced waterproof installation details minimize through-fastener and rake-edge leak paths during atmospheric river-driven downpours
⢠Panels designed to shed snow and limit buildup, helping prevent ice-dam formation during occasional freezeāthaw cycles on island properties
⢠Class A fire-rated available to provide ember resistance and enhanced fire performance during regional dry spells or brush-fire risk periods
⢠UL 2218 Class 4 impact resistance for protection from hail, falling branches tied to island storm debris, and rooftop impacts
⢠Engineered profiles support mechanical fastening and standing-seam attachment for robust wind uplift resistance on exposed Thatcher ridgelines
⢠Energy-efficient cool-roof characteristics reduce summer heat gain in unshaded attic spaces and improve indoor comfort during warm spells
⢠Solar-compatible decking and attachment zones engineered to accept modern bracket-mounted photovoltaic systems typical on San Juan County homes
⢠Low-maintenance, fully recyclable aluminum reduces long-term replacement cycles compared with organic roof coverings in damp coastal climates
⢠Specifically formulated to resist accelerated finish degradation from salt-fog corrosion found on properties facing marine channels
⢠Designed to inhibit moss, lichen, and algae accumulation on persistently damp, shaded roofs common across Thatcher properties
⢠Backed by a transferable lifetime-limited warranty and documented installation standards for resale and long-term asset protection

InterlockĀ® Aluminum Roofing ā all-climates performance specs for Thatcher, Washington
| 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 (wonāt 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. (Add exact alloy + thickness for maximum spec proof.) |
| 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. |
