UL Certification 2218 Class 4 - A Milestone for Metal Roofing.

Interlock Roofing Ltd. announces the successful completion of benchmark tests meeting the standard of Underwriters Laboratory Standard 2218 Class 4, Impact Standard for Impact Resistance of Prepared Roof Covering Materials.

According to Gordon Warren, Product Manager, surpassing this quality standard is milestone for endurance that all manufacturers of quality metal roofing components hope to achieve. We have invested tremendous efforts to ensure our products can deal with all kinds of impact resistance scenarios, including hail. This ruling applies to three of our key product profiles… shingle, shake and tile. Our team is most pleased to present our products to the public with the assurances that UL 2218 confirms. Some homeowners with metal roofing systems meeting UL 2218 can actually qualify for deductions on their homeowners insurance.
