Which is better EPDM or TPO roofing?

Which is better EPDM or TPO roofing?

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

Is TPO good roofing?

TPO (thermoplastic polyolefin) is a single-ply white membrane used in both commercial and residential roofing. Due to TPO being a white membrane, it reflects heat instead of absorbing it. If you have a flat roof or a low-slope dormer over a bedroom, TPO is a great option because it’ll keep the room below cooler.

Is Carlisle TPO good?

Carlisle’s Sure-Weld TPO membranes have the industry-leading OctaGuard XT weathering package for enhanced long-term weathering. With high reflectivity and strong heat-welded seams, TPO is a great choice many different types of buildings.

Is EPDM cheaper than TPO?

EPDM roofs are the most economical choice for single ply roofing membranes. 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.

How long does TPO roof last?

What is the life expectancy of a TPO roof? A thermoplastic Olefin (TPO) roof typically lasts as little as 22 years and up to a maximum of about 30 years. The two thermoplastic layers are adhered to a polyester scrim for reinforcement, becoming a single ply to protect your roof.

Is TPO roofing expensive?

Although many different factors can influence the price of your roof, in most cases, you can expect to pay between $3.50 and $9.50 per square foot. Overall, TPO roofing costs typically range between $7,000 and $11,500.

What class is TPO roofing?

Class A Fire-
Class A Fire-Rated – TPO membranes and EPDM can achieve Underwriters Laboratories (UL) Class A fire resistance listings by adding fire retardant chemicals during the manufacturing process.

Does TPO roofing need underlayment?

Thermoplastic Polyolefin (TPO) TPO roofs can resist UV rays by reflecting the light off its surface. This makes TPO ideal for buildings that need an effective insulation system. TPO underlayment is relatively easier to install. A hot-air gun is used to melt the rubber down to fuse each sheet together.

What do you put under TPO roofing?

Sometimes an underlayment is needed under the insulation layer. The underlayment is normally a 5/8″ gypsum board and is typically installed when an improved fire resistive rating is required or to create a solid substrate on top of a fluted metal deck.

How much is a roll of TPO cost?
