Antorch
Antorch (Residential)
Protect your flat or low-slope residential roof with the ultimate waterproofing solution. Our residential torch down services provide a high-performance, multi-layered bitumen membrane that is heat-welded to create a seamless, impenetrable barrier. Perfect for modern home designs, balconies, or garage additions, this system ensures your living space remains dry and protected even during the heaviest Southern California rains.
Seamless Waterproofing: Heat-fused application creates a single, continuous layer that eliminates common leak points.
Superior UV Resistance: Specialized mineral granules reflect solar heat, protecting the membrane from sun damage and aging.
Enhanced Puncture Resistance: High-density modified bitumen that withstands foot traffic and falling debris.
Long-Term Flexibility: Engineered to expand and contract with temperature changes without cracking or brittle failure.
Antorch (Commercial)
Maximize the lifespan and reliability of your commercial facility with our heavy-duty torch down roofing installations. Designed specifically for flat-roofed warehouses, retail centers, and industrial buildings, our commercial-grade bitumen systems provide a rugged, fire-resistant shield against the elements. We focus on precision application to ensure your business assets, inventory, and operations are secured by a roof that is as tough as your business.
Industrial-Strength Durability: Multi-ply systems engineered for maximum structural integrity in high-traffic commercial environments.
Coastal-Grade Protection: Highly resistant to the corrosive effects of salt air, moisture, and high coastal winds.
Maximum Fire Safety Ratings: Utilization of fire-retardant membranes to meet the most stringent commercial safety codes.
Operational Efficiency: Fast, professional installation designed to minimize disruption to your business schedule and tenants.
