What is TPO roofing material?
Before we dive into details, let us first define what is TPO roofing material? TPO stands for Thermoplastic Olefin. It is a single-ply thin roofing membrane that has unique features. Its thickness reaches 45 to 80 millimeters. TPO is thick enough to create a watertight seal around your roof. Due to its promising qualities, it is easily a top-of-mind choice when it comes to commercial or industrial constructions.
Since the 1980s, TPO roofing material is widely used by contractors and property owners. This is in response to the demand for a heat-reflective and energy efficient roofing system. This rubber-based membrane is produced by combining polypropylene and ethylene-propylene rubber. It is then blended with fiberglass filler, carbon fiber, and talc. These additives strengthen the base and help achieve its energy-saving properties.
These are the common methods on how to apply TPO on to the surface:
- Mechanically attached
- Plate bonded
Applied in large rolls, the seams of this roofing materials are hot air-welded together in order to form waterproof sheets.
TPO is mostly used for low slope commercial roofing along with other materials:
- Felt – They are waterproof and cost-effective. You can choose to install them with only $0.38 per square foot. However, felt is prone to plant growth that may cause long-term damage.
- Rubber/EPDM – EPDM or ethylene propylene diene monomer is lightweight, durable, and waterproof. It could be prone to leaks and damages if edges are not properly sealed during installation. It is also one of the cheapest options costing only $0.80 per square foot.
- Polyvinyl Chloride (PVC) – It is a durable thermoplastic membrane. PVC is known for its longevity and impressive performance. It has great insulation properties and can block UV rays. However, PVC is also very expensive. It costs around $6 to $10 per square feet.
- Metal – They are lightweight and easy to install. The downside is their cost. For one, aluminum is extremely expensive costing around $889-$1,000 per square foot. There are other options under this which include steel and copper.
- Tar and Gravel – The sturdiest and heaviest among all the choices. It is 100% waterproof, non-corrosive, and can reflect ultraviolet rays. It costs around $4 per square foot with a lifespan of 20 to 25 years only.
- Asphalt – Because of its weight, it could be difficult to install. However, it could last up to 50 years. Asphalt is moldable and easy to repair. It is very affordable costing only $2.5 to $4 per square feet.
