How can you tell the difference between TPO and EPDM roofing?

EPDM has a dark surface, which in summer conditions will absorb heat, forcing cooling systems to work overtime, whereas TPO roofing reflects sunlight, allowing commercial air conditioners to work more efficiently. TPO also has a somewhat higher resistance to punctures than EPDM.

How do I know what kind of flat roof I have?

If your roof appears reflective white or gray in color and has what looks like a sprayed-on pattern, you likely have a polyurethane flat roof. In the installation of SPF, base layers of dense polyurethane foam are sprayed onto the surface of the roof with a sprayer or wand.

What does TPO roof look like?

Reflective and Penetrable – Most TPO is usually white and extremely reflective. While in contrast, EDPM is often black because of the membrane’s natural color and its retention of the sun’s rays. Single-ply membrane roofing has become one of the top roofing materials for most commercial facilities.

Is TPO compatible with EPDM?


TPO is a versatile membrane and can be installed in a variety of ways including mechanically attached, adhered, and with the RhinoBond®*** System. RhinoBond® is an electromagnetic induction welding system and cannot be used with thermoset products such as EPDM.

Is TPO more expensive than EPDM?

TPO roofing membranes are more expensive than EPDM. Regardless of which membrane you choose, it is better to spend more money and invest in a thicker membrane. Both EPDM and TPO roofs perform better and last longer if they are thicker.

Can you coat a TPO roof?

Silicone and acrylic coating systems are both great choices for restoring and extending the life of a TPO roofing system. Ageing gives the membrane surface a matte finish that more readily accepts a coating, helping ensure long-lasting, weathertight performance. …

What are flat roofs covered with?

Metal is one of the few materials that can be used for both pitched roofs and flat roofs. Flat or low-slope roofs can be covered with steel, aluminum, zinc, or copper just like pitched roofs. However, metal shingles are not practical for flat roofing and so roofers recommend standing-seam and screw-down metal panels.

As a result, commercial roofing contractors commonly price TPO roofing between $700 and $1,300 per square.

Can EPDM be heat welded?

Yes! The membrane can be joined and sealed by using a hot air gun with a flat nozzle and seam roller to creat a heat weld.

Can TPO be glued?

A TPO roof can be installed fully-adhered, mechanically-attached or ballasted. When the TPO roof is fully adhered it means that the membrane was glued to the substrate using a special strong adhesive that creates a chemical bond with the TPO.
