What is TPO Roofing?

Thermoplastic Polyolefin (TPO) is a single-ply roofing membrane that’s gaining popularity in the commercial roofing industry.
Known for its bright white surface, TPO reflects UV rays, helping to keep your building cool and reduce energy costs. Made from a mix of polypropylene and ethylene-propylene rubber, TPO roofing is tough, flexible, and kind to the environment.
  • Energy Savings: Reflective properties reduce cooling costs.
  • Eco-Friendly: TPO is recyclable and free from harmful chemicals.
  • Fire Resistance: Achieves Class A fire resistance ratings.
  • Versatility: Suitable for various building types and sizes.
  • Energy Efficiency: TPO’s reflective surface helps lower cooling costs by reflecting sunlight and heat away from your building.
  • Durability: With proper installation and maintenance, TPO roofs can last 20 to 30 years, providing long-lasting protection.
  • Flexibility: TPO membranes come in large rolls, which are ideal for covering wide, flat roof spaces.
  • Cost-Effective: TPO roofing systems offer excellent value for money, often proving more economical than other roofing options. They provide high performance without the high price tag, making them a wise investment for your business.
  1. Preparation: We start by cleaning or removing the existing roof substrate to prepare for installation.
  2. Insulation Installation: Depending on your needs, we install Polyisocyanurate (Polyiso), Expanded Polystyrene (EPS), or Extruded Polystyrene (XPS) insulation to enhance your roof’s thermal performance.
  3. Membrane Attachment: The TPO membrane is either adhered to the cover board with a bonding adhesive or mechanically fastened.
  4. Seam Welding: Our certified technicians use hot-air guns to weld the seams of the TPO membrane, ensuring a watertight seal.
