As an awarded KCDA Vendor (Contract #25-412), Impervious provides members with a turn-key, compliant, and cost-effective solution for roof restoration, waterproofing, and energy-efficient building envelope protection.

Comprehensive Roofing Solutions
Impervious offers a full suite of roof restoration and coating systems engineered for long-term performance across commercial, industrial, educational, and municipal facilities, including:
•    Silicone Roof Coatings (ProSil Alkoxy Silicone) – Designed for maximum UV resistance and ponding-water protection, this seamless membrane delivers exceptional waterproofing, flexibility, and long-term reflectivity—ideal for high-exposure or flat-roof applications.
•    Urethane Systems (UreFlex Series) – A two-component urethane system providing superior adhesion, chemical resistance, and elongation for demanding industrial environments where long-term durability and flexibility are essential.
•    FiberSeal Base Roof Coating System – A proprietary fiber-reinforced, spray-applied leak-proofing system developed by Impervious to replace outdated polyester fabric and seam-tape methods that can damage metal roofs. FiberSeal Base forms a seamless, breathable, and flexible waterproof barrier across seams, fasteners, and penetrations—saving labor, reducing material waste, and extending the service life of metal, mod-bit, and single-ply roofs.
•    Metal Roof Restoration Systems – Complete restoration of metal roofing assemblies including rust-inhibiting primers, fastener encapsulation, seam reinforcement, and full-surface waterproof coatings for a watertight, reflective, and corrosion-resistant finish.
•    Seam and Penetration Reinforcement – Advanced mastics and fabric-reinforced applications that permanently seal critical transitions, flashings, and penetrations to ensure full system integrity and leak protection.

•    Comprehensive Roof Inspections & Condition Reports
