TPO/PVC Roofs

TPO (Thermoplastic Olefin) and PVC (Polyvinyl Chloride) are both single-ply roofing membranes commonly used on flat or low-slope roofs, but they differ in composition and performance. TPO is a newer, more cost-effective option made from a blend of rubber and plastic, offering excellent UV resistance and energy efficiency. PVC, on the other hand, has been used for decades and contains plasticizers that give it greater flexibility and chemical resistance, making it ideal for restaurants or buildings with grease or oil exhausts. Both are durable and heat-welded at the seams, but the best choice depends on your building’s specific needs and environment.

A properly installed and maintained TPO or PVC roof typically lasts between 20 to 30 years. Factors like climate, roof slope, and exposure to harsh elements can affect longevity, but both materials are known for their durability and resistance to UV rays, punctures, and chemical exposure. Regular inspections and maintenance can help extend the lifespan of your roof even further.

Yes, TPO or PVC roofing can often be installed over an existing flat roof, provided the underlying structure is in good condition. Before proceeding, a professional roofer will inspect the existing roof to ensure there are no moisture issues, damage, or structural concerns. Installing over an existing roof can reduce labor costs and minimize disruption, making it a cost-effective solution for many property owners.

TPO and PVC roofs are highly resistant to UV rays and chemical exposure, making them ideal for commercial and industrial buildings in Texas. Both materials are designed to reflect sunlight, reducing heat absorption and improving energy efficiency. Additionally, they resist damage from grease, oils, acids, and other common industrial chemicals, which helps extend their lifespan and maintain performance in harsh environments.

TPO and PVC roofs require minimal maintenance, but routine inspections are key to maximizing their lifespan. It’s recommended to check the roof at least twice a year—especially after severe weather—to look for punctures, seam separations, or debris buildup. Keeping the surface clean and ensuring proper drainage will help prevent long-term damage. Promptly addressing minor issues can prevent costly repairs down the line and keep your roofing system performing efficiently.

Yes, both TPO and PVC roofing systems are excellent choices for commercial buildings. They offer outstanding durability, energy efficiency, and resistance to UV rays, chemicals, and punctures—making them ideal for flat or low-slope commercial roofs. Their reflective properties help reduce cooling costs, and their ease of installation means less disruption to business operations. With proper installation and maintenance, TPO and PVC roofs can provide long-lasting protection for a wide range of commercial facilities across Texas.
