TPO Roofing System Concerns
What is the Purpose of Installing a TPO Roofing System?
Before investing in a TPO roofing system, it is important to clearly understand your objective. Are you aiming to cut down on cooling costs? Is your existing roof failing due to UV exposure or ponding water? TPO (Thermoplastic Polyolefin) roofing is widely chosen for its ability to reflect sunlight, resist UV damage, and handle chemical exposure—ideal for flat or low-slope roofs common in commercial structures.
If energy efficiency is a top priority, TPO is a smart contender. Its white reflective surface significantly reduces heat absorption, which in turn lowers indoor cooling demands. For business owners in Hemet, CA—where the summer sun can be relentless—this can translate into meaningful long-term savings on utilities.
However, if your building faces other specific challenges, such as heavy foot traffic on the rooftop or persistent drainage issues, you may want to evaluate additional reinforcements or alternative roofing types before finalizing your decision.

Is My Existing Roof Compatible with TPO Installation?
Not all commercial roofing systems are created equal, and the condition of your existing roof can heavily influence the success and cost of a new TPO installation. Ask yourself: Is your current roof in good enough shape for repair or roof restoration, or will it require a full tear-off? The answer will impact both budget and construction timelines.
TPO roofing systems can be installed over certain existing roof types—such as built-up roofing or EPDM—if the underlying structure is sound. However, problems like water-damaged decking, mold growth, or insulation degradation may require more extensive preparation. An inspection from a qualified commercial roofer is crucial before making this decision.
For building owners in Hemet, CA, where roofs can take a beating from sun exposure and occasional storms, understanding the current condition of the structure is an essential first step.
How Long Do I Plan to Stay in This Building?
A TPO roofing system offers excellent longevity, typically lasting between 20 and 30 years when properly installed and maintained. But ask yourself: How long do you plan to own or lease this building? If the property is a long-term asset, the upfront investment in a durable and energy-efficient roofing system makes strong financial sense.
On the other hand, if you are planning to sell the property within a few years, consider whether the roof upgrade will significantly increase resale value or make the building more marketable. TPO’s reputation for low maintenance and high performance can be attractive to buyers, making it a solid selling point.
For commercial property owners in Hemet, CA, making this decision in light of future business plans ensures that the roofing investment aligns with both short- and long-term goals.

FAQ
What is a TPO roofing system made of?
TPO stands for Thermoplastic Polyolefin, a single-ply roofing membrane composed of synthetic materials and a reinforcing scrim. It is known for flexibility, heat resistance, and ease of installation.
How does TPO compare to other roofing materials?
TPO is typically more cost-effective than PVC and more UV-resistant than EPDM. It also offers better energy efficiency due to its white reflective surface, making it ideal for hot climates like Hemet, CA.
Can TPO be repaired easily if damaged?
Yes, TPO membranes can be heat-welded for effective repairs, especially if the damage is detected early during routine maintenance checks.
Is TPO resistant to chemicals and grease?
TPO holds up well against general environmental exposure, but in areas where grease or harsh chemicals are common (like restaurants or factories), reinforced options or protective mats may be necessary.
How often should a TPO roof be inspected?
It is recommended to inspect your TPO roof at least twice a year—typically in the spring and fall—to catch any issues early and extend the life of the system.
