Metal Roofing Built for Westchester's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection
Interlock Metal Roofing is a trusted metal roofing contractor and exclusive authorized installer of Interlock® lifetime aluminum roofing systems serving homeowners in Westchester, Cook County, Illinois. Founded May 17, 2001, we provide roof replacement and re-roofing across Westchester with heavy-gauge, fire-resistant, energy-efficient cool roof solutions engineered for performance, beauty, and durability.

- Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events.
- The aluminum is coated with the Alunar® Coating System (no visible aluminum surface) for durable, low-reflectivity finish and enhanced corrosion resistance.
- Designed for Midwest snow loads — snow-shedding metal panels reduce buildup and help prevent ice dams during Westchester’s frequent freeze–thaw cycles and lake-effect snow.
- Proven impact performance: UL 2218 Class 4 resistance against hail, falling branches, and storm debris.
- Class A fire-rated available for improved flame and ember resistance during seasonal dry periods.
- Tested to 120+ mph (193+ km/h) wind performance to resist severe windstorms and gusts that affect Cook County structures.
- Low thermal mass and cool-roof properties reduce attic heat gain during Illinois summer heat waves and improve year-round comfort.
- Installation details limit freeze–thaw movement and thermal cycling stress common to Westchester roofing assemblies.
- Standing-seam mechanical fastening uses concealed clips to allow thermal expansion while preserving weather-tight integrity.
- Solar-compatible roof surface engineered to accept modern bracket-mounted photovoltaic systems on Westchester homes.
- Fully recyclable aluminum and long service life lower lifecycle environmental impact for Cook County homeowners.
- Smooth, Alunar®-coated surfaces minimize biological accumulation and simplify maintenance on shaded Westchester roofs.
- Coastal salt air — not a primary concern for inland Westchester, but Alunar® coating still provides resistance to urban pollutants and lakefront moisture exposure.
- Atmospheric rivers — rare in inland Illinois; the system’s precision seams and mechanical fastening nonetheless protect Westchester homes during heavy rain and storm events.

Interlock® Aluminum Roofing — all-climates performance specs for Westchester, Illinois
| 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:
Our house was built in 1926and we were replacing the original slate roof. The style of the house deserved the look and durability of an interlock roof to preserve the architectural style and provide matching longevity. We had multiple contractors involved in a total exterior renovation, in addition our water main, sewers and streets were under construction. The Interlock team worked through property access and coordinated how other exterior renovations would work with the new roof.
