Here is why a Lewis Walker Roofing GAF TPO Roof might be the right choice for you:


In buildings that use natural gas, heat, and electric air conditioning, reflective TPO can save money on energy costs* compared to dark EPDM. This is true in the sunbelt as well as the snowbelt, thanks to the simple fact that the color of the roof only matters in sunlight. And when the snow melts, an EPDM roof becomes a dark, heat-absorbing sponge — just when you want to reflect sunlight away.

On average, electricity costs 4 times more, per BTU, than natural gas. That doesn’t even include electricity demand charges, which can account for 30 — 70% of a total electricity bill. Want to know more? Check out our Cool Roofing page.


Punctures often equal leaks. EverGuard® TPO offers greater puncture resistance than reinforced EPDM — up to three times the puncture resistance of non-reinforced EPDM of the same thickness.


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. It’s a great way to achieve the look and performance of an adhered system when it is too cold to use adhesives.

GAF offers many different adhesives to install both smooth and fleece-back membranes, including low-VOC options. Install fleece-back TPO in as low as 25°F with LRF M Low-Temperature Adhesive.


TPO is thermoplastic, so you can heat-weld seams, and it’s ideal for repairs. Simply clean the membrane and heat-weld directly to it. EPDM cannot be welded and cannot be re-taped when the weather is too cold to use primer and adhesives, requiring a temporary fix until the weather warms up.


TPO has better dimensional stability than EPDM. EPDM is more likely to shrink which can cause a variety of problems on your roof.


An effective roofing system depends on strong seams. EverGuard® TPO’s welded seams are stronger than taped EPDM seams. By welding the seams, TPO becomes one monolithic membrane across the entire roof.
