Fastened
The membrane is mechanically-fastened to the roof deck using heavy-duty screws and plates.
Introduction to TPO Roofing
What is TPO roofing?
TPO (thermoplastic polyolefin) is a single-ply membrane used in low-slope or flat roofing systems. For the past few decades, TPO has been a popular and reliable roofing solution, due to its flexibility, reflectivity, ease of installation, and durability for commercial and industrial buildings.
Properties and characteristics of TPO membranes
TPO is a thermoplastic membrane made of a combination of ethylene-propylene rubber and polypropylene. It has a white color to reflect sunlight and reduce surface temperatures, and is easy to install with a choice of multiple application methods. Because of TPO’s flexibility, no plasticizers are required, which enables the membrane to withstand ordinary building movement.

TPO Maintenance Tips
Regular maintenance of a TPO roof is essential for extending its service life and ensuring its performance.
Routine maintenance tasks for TPO roofs
- Ensure that TPO roof drains properly
- Remove debris from TPO roof's surface
- Schedule regular inspections for your TPO roof
- Clean TPO roofing material according to manufacturer's guidelines
Cleaning and inspection guidelines for TPO membranes
Schedule regular inspections annually or after a severe weather event to check the TPO seams and ensure there are no areas where water can intrude. Different factors, such as dirt and dust accumulation, rainfall, and heavy winds, will determine how often a TPO roof needs to be cleaned. Removing debris and regularly washing the roof will help keep the TPO membrane’s white surface so it can maintain its reflective properties.

Frequently Asked Questions
What are the the benefits of reflective roofs?
TPO roofs reflect sunlight and heat, reducing rooftop temperatures, potentially helping to lower interior building temperatures.
What are the differences between TPO and EPDM?
The choice between EPDM and TPO roofing depends on a number of factors, including climate, budget, and level of durability required. For instance, EPDM is known for its durability and flexibility, while TPO performs extremely well in resisting punctures and impacts, but its effectiveness is heavily influenced by factors such as membrane thickness and installation method. While EPDM is a low-cost material, TPO is also a low-cost option, but it reflects UV rays and heat, so it is a suitable choice for building owners looking for energy efficiency.
