TPO vs. PVC Roofing in Los Angeles: Which Is Best for Your Building?

Commercial roofing in Los Angeles comes with unique challenges. From high UV exposure and seasonal rain to Title 24 energy code requirements, choosing the right roofing material is critical. Two of the most popular options for flat and low-slope roofs are TPO (Thermoplastic Olefin) and PVC (Polyvinyl Chloride). But which is better for your building?

This detailed comparison will help Los Angeles property owners understand the differences between these single-ply membranes to make a well-informed decision.

TPO Roofing: Affordable & Energy Efficient

TPO roofing is known for being a cost-effective and energy-efficient option. Its white reflective surface meets California’s Title 24 requirements and helps reduce cooling loads during LA’s hot summers. TPO is also resistant to UV rays, dirt buildup, and microbial growth.

Lower upfront cost compared to PVC
Heat-welded seams for durability
Highly flexible and lightweight

PVC Roofing: Chemically Resistant & Long-Lasting

PVC roofing is ideal for buildings exposed to oils, chemicals, or grease—such as restaurants, warehouses, or factories. It offers excellent fire resistance and is extremely durable under stress. Though more expensive upfront than TPO, PVC often lasts longer with fewer repairs.

High resistance to chemicals and punctures
UV stable and low maintenance
Longer lifespan with proper installation

Which Roofing System Should You Choose?

When deciding between TPO and PVC roofing in Los Angeles, consider your building’s use and budget. If cost and energy efficiency are your top concerns, TPO may be the better fit. For environments that face chemical exposure, PVC is typically the smarter long-term choice.
