Commercial Roofing Built for San Diego’s Toughest Conditions
Commercial Buildings Need Better, Longer-Lasting Roofing
Commercial roofs face extreme conditions — heat, rooftop equipment, foot traffic, and chemical exposure. Old-school systems like BUR or modified bitumen break down faster, cost more to maintain, and react poorly to today’s climate demands.
Weather-Tech installs modern thermoplastic systems designed for cleaner welds, lower energy costs, and decades of performance.
Common symptoms:
• Rising energy bills
• Leaks around vents, curbs, or equipment
• Brittleness or cracking in older membranes
• Ponding water or poor drainage
• Failed seams or improper past repairs
• High maintenance costs due to old roofing systems
