Single-Ply TPO Roofing

What is TPO roofing?

Thermoplastic Polyolefin (TPO) roofing is a single-ply roofing membrane that’s used for low-slope and flat roofs on commercial and residential buildings.

  • TPO is made of a combination of polypropylene and ethylene-propylene rubber. It’s typically white and has a shiny, reflective appearance.
  • TPO is attached to the roof with adhesives, mechanical fasteners and heat welding. 

TPO is the short name for thermoplastic polyolefin. This innovative material is made up of polypropylene, a chemical compound known for its elasticity and durability and commonly used in the manufacturing of a slew of both industrial and household products. Polypropylene is also known for its slippery characteristic, which means it can work well to repel moisture from potential roof wreckers like rain or snow.

The other important component of TPO is ethylene-propylene rubber, a synthetic elastomer related to rubber. TPO material is typically manufactured in sheets that are available in various sizes, and is distinguished by its bright white color. Because of this substance’s ability to resist weather, ozone rays, heat and oxidation, it is an ideal ingredient for this type of application.

What we do

Step 1: Preparation and Cleaning
Roof Inspection: Thoroughly inspect the existing roof for damage, leaks, or unevenness.

Removal: If necessary, remove the old roofing material and clean the roof surface.

Repair: Address any underlying structural issues or damage to the roof deck.

 
Step 2: Insulation
Insulation Installation: If required, install insulation to improve energy efficiency and thermal performance.
 
 
 
Step 3: Primer Application
Apply a compatible primer to the prepared roof surface to ensure proper adhesion of the TPO membrane.
 
 

Step 4: TPO Membrane Installation
Membrane Placement: Unroll the TPO membrane onto the roof, starting from the lowest point.
 
Adhesion: Secure the membrane using mechanical fasteners, adhesive, or a combination of both methods, depending on the chosen installation system.
 
Seam Welding: Heat-weld the seams between the TPO sheets to create a watertight seal.
 


Step 5: Flashing and Accessories
Flashing Installation: Install flashing around penetrations, such as pipes, vents, and skylights, to prevent leaks.

 
Accessory Installation: Install any necessary accessories, such as drains, gutters, and scuppers.
 
 

Step 6: Quality Control and Inspection
Inspection: Conduct a thorough inspection of the completed roof to ensure proper installation and adherence to building codes.
 
 
Final Touches: Address any minor issues or imperfections before finalizing the project.
 
Note: The specific steps and materials used in the TPO roofing process may vary depending on the manufacturer’s instructions, local building codes, and the specific requirements of your project.
 

Benefits of TPO

Cost-effective: TPO is more economical than other roofing materials like PVC and EPDM.
 
Energy efficient: TPO can be used with insulation to improve energy efficiency and reduce heating and cooling costs.
 
Weather Resistance: TPO is UV-resistant and can withstand extreme temperatures, making it suitable for various climates.
 
Durable: TPO is resistant to tears, punctures, abrasion and mold growth, ensuring long-lasting performance..
 
Easy to install: TPO comes in large rolls that are laid out on the roof and welded together at the seams.
 
Environmentally friendly: TPO is a recyclable material, making it a more environmentally sustainable choice.
 
Low Maintenance: TPO requires minimal maintenance, reducing long-term costs.
 
Long lifespan: From 20 to 30 years, depending on factors such as installation quality, maintenance, and environmental conditions.
