Commercial & Industrial Roofing Built for San Diego’s Toughest Conditions
Commercial Buildings Need Better, Longer-Lasting Roofing
Commercial roofs face extreme conditions such as heat, rooftop equipment, foot traffic, and chemical exposure. Old systems like BUR or modified bitumen break down faster, cost more to maintain, and struggle in today’s climate.
Weather-Tech installs modern single-ply thermoplastic systems designed for cleaner welds, lower energy costs, and decades of performance.
We are certified specialists in commercial and industrial roofing systems across San Diego County, with over a decade of proven experience installing TPO and PVC flat roofing systems for warehouses, retail buildings, office spaces, and industrial facilities.
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
Advanced Roofing Systems Built for Commercial & Industrial Buildings
Single-ply membrane roofing has become the standard for commercial and industrial properties. These systems deliver strong durability, energy efficiency, and long-term performance in San Diego’s demanding climate.
Weather-Tech Roofing installs TPO, PVC, and advanced membrane systems as a certified installer for leading manufacturers. That means every system is installed correctly, performs as designed, and qualifies for full manufacturer-backed warranties.

TPO Roofing
Thermoplastic Polyolefin
TPO is one of the most popular and cost-effective single-ply roofing systems available today. It is a system we have been installing and refining for over a decade. TPO membranes reflect UV rays, help reduce cooling costs, and perform well in San Diego’s high-heat environment.
Heat-welded seams create a watertight bond that is stronger than the membrane itself. The system also works well with rooftop equipment, walkways, and HVAC installations commonly found on commercial buildings.
Key Benefits:
• Energy Star rated and helps reduce cooling costs
• Resistant to UV exposure, ozone, and chemical damage
• Flexible and resistant to cracking in all temperature ranges
• Available in multiple thickness options for different applications
PVC Roofing
Polyvinyl Chloride
PVC has been a trusted commercial roofing system for over 50 years, and Weather-Tech has been installing it with precision for more than a decade. It is known for its strong resistance to chemicals, grease, and fire, making it a great choice for restaurants, manufacturing facilities, and industrial buildings.
PVC membranes are also recyclable and offer long-term performance in demanding environments.
Key Benefits:
• Strong resistance to chemicals and grease
• Class A fire rating for added protection
• Remains flexible even in cooler temperatures
• Excellent long-term durability and dimensional stability
KEE Roofing
Ketone Ethylene Ester
KEE membranes are a more advanced single-ply roofing option designed for long-term performance. They are engineered to maintain flexibility and strength over time without becoming brittle.
Where standard PVC systems can stiffen with age, KEE membranes remain consistent and reliable. This makes them a strong choice for commercial and industrial buildings that require long-lasting performance.
Key Benefits:
• Maintains flexibility over time without becoming brittle
• Performs well in extreme temperatures and standing water
• Resistant to chemicals and harsh rooftop environments
• Strong weldability for long-term watertight performance
