UL 2218 Class 4 — top hail rating

  • Authorized Interlock® Lifetime Aluminum Roofing Systems installer serving Grayslake and Lake County homeowners
  • 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 panels coated with the Alunar® Coating System (no visible aluminum surface) for durable, fade- and corrosion-resistant finish
  • Built to withstand Lake County winters—panels shed heavy snow loads and tolerate repeated freeze–thaw cycles common in Grayslake
  • Reduces ice-dam formation through continuous, smooth panel coverage and rapid snow-shed characteristics important during Grayslake freeze–thaw transitions
  • Interlocking panel system tested to 193+ km/h (120+ mph) to resist severe wind events and gusts that can impact northeastern Illinois properties
  • Provides UL 2218 Class 4 impact resistance for hail, falling branches, and storm debris typical of Midwestern thunderstorm seasons
  • Class A fire-rated available for added protection and code compliance where required in Lake County
  • Energy-efficient cool-roof performance lowers attic temperatures during Midwest heat waves and improves indoor comfort in Grayslake homes
  • Solar-compatible roof platform designed to accept modern bracket-mounted photovoltaic systems used across Lake County
  • Fully recyclable aluminum construction supports sustainable building practices for environmentally conscious Grayslake homeowners
  • Lower maintenance than asphalt shingles in Grayslake’s seasonal wetting and drying—no rot, no granule loss, minimal routine care
  • While atmospheric rivers are not a Midwest phenomenon, the system is engineered for episodic heavy rainfall and wind-driven storms that affect Grayslake
  • Not exposed to coastal salt air; Alunar® coating still protects roof panels from corrosion caused by winter road-salt splash and de-icing residues in Lake County
  • Smooth, coated panel surfaces deter moss and algae growth on shaded Grayslake roofs, reducing cleaning frequency and preserving drainage performance

Interlock® Aluminum Roofing — all-climates performance specs for Grayslake, Illinois

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

Review: September 22, 2017Completion: August 31, 2017

This is probably not the fault of Interlock Roofing but the materials were delivered six weeks before the work began,were left on our lawn and killed the grass where they were placed. We were also concerned about theft when we were not at home. I hesitate to mention this but it was a concern at the time. We love our roof and are for once looking forward to the first snow without worrying about leaks.

Review: January 12, 2016Completion: November 15, 2015

Interlock Roofing could have improved because they had one roofer that not show up one day and when this happened, it took another day to complete the project. This the second time I've had a roof put on in three years. This time was from tornado damage in my area. I am happy with them because I would not have asked them a second time.
