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.

Which is better EPDM or TPO?

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

Are TPO roofs expensive?

TPO roofing material is known to be both practical and cost-effective. It's typically less expensive than EPDM, and it even tends to last longer with less maintenance. 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.

Is EPDM same as TPO?

Believe it or not, TPO is actually in a broad family of rubber roofing materials. TPO is a blend of polypropylene and ethylene-propylene rubber. EPDM stands for Ethylene Propylene Diene Monomer. It is a synthetic rubber derived from oil and natural gas (ethylene propylene).

How long does TPO roof last?

It comes in a variety of thickness ranging from 45 mil to 80+ mil which can fit within a wide variety of budgets. 80-mil TPO roofs come with up to a 25-year warranty and with the appropriate maintenance, it is not uncommon for a TPO roofing system to last as long as 30 years.

EPDM vs TPO Flat Roof - What's The Difference?

Is TPO good for flat roof?

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. You can also use it over a non-living space like a garage or covered patio.

Can you put TPO over EPDM roof?

Yes. Recovering with TPO is a great option for a building with an aging EPDM roofing system. It's easy. It's far less costly and disruptive than a full tear-off.

What type of roofing is best for a flat roof?

PVC roofing

Polyvinyl chloride (PVC) roofing membranes have been heralded as one of the best flat roofing materials in the single-ply roofing industry. The material is made from processed petroleum or a natural gas and salt mixture.

How much does EPDM cost?

For EPDM roofing membrane, you can expect to spend somewhere between $3.25 and $14.75 per square foot for the material and installation. In most cases, the price will average about $4.50 and $5.50 per square foot.

Is TPO or PVC more expensive?

However, with all material variables constant, TPO membrane is more affordable than PVC membrane per square foot. On average, a TPO roof with installation only costs around $5.50-$6.00 per square foot, while a PVC roof costs $6.50-$8.00 for the same size.

Is TPO roof better?

While TPO roofing compares to PVC roofing in terms of benefits, such as energy efficiency and being heat weldable, selecting a TPO roof is far more economically advantageous.

Is TPO roof any good?

TPO is very good at resisting dirt build-up, punctures, and tears as well. This means a strong roofing product that can save you money in the long run as the roof will need to be cleaned less often.

Which is cheaper TPO or EPDM?

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. Both EPDM and TPO roofs perform better and last longer if they are thicker.

Can you put TPO over existing roof?

If the existing roof is in good enough condition, a TPO membrane can beapplied over an existing roof system after an insulation board has been applied over anexisting built-up roof system or other single ply membrane.

How thick should a TPO roof be?

TPO is a type of roofing membrane that can come in a variety of thicknesses. The most common thickness is probably 60 mils. (A mil is a unit of measure where 1-mil is equal to 0.001 inches. So, a 45-mil roofing membrane is actually 0.045 inches thick; whereas a 60-mil membrane is 0.06 inches thick, and so on.)

What is the longest lasting flat roof material?

EPDM, or Ethylene Propylene Diene Monomer, is known as the longest-lasting flat roof material. It's designed to withstand the most extreme weather conditions that a flat roof can face, and this durability can help it last at least 30 to 50 years.

Is EPDM good for flat roofs?

EPDM Flat Roofs

The EPDM roofing system has grown over the last few decades on the strength of its reputation as a durable, inexpensive roofing option. These traits have spurred its growth and have made it the most common commercial flat roof choice in the US today. It is also revered for its quick installation.

How long do EPDM roofs last?

EPDM roof membranes remain stable over time and can have a life expectancy of over 50 years. ** Made from synthetic rubber, EPDM roofing membranes have two primary ingredients, ethylene and propylene, which are derived from oil and natural gas.

Can you Weld TPO to EPDM?

The problem is that EPDM relies on adhesives to hold the seams and flashing details together. With TPO and PVC roof systems, the seams and flashings are heat welded, which means that the product becomes one sheet. With EPDM, heat welding is not possible, so primers and adhesives are used.

How do you maintain a TPO roof?

Which is better TPO or PVC?

While PVC offers better resistance to puncture and weathering, TPO (like PVC) is recyclable and environmentally friendly. Its reflective surface reduces UV radiation and helps with energy efficiency.

Is TPO roof slippery?

TPO is a single-ply material and is not designed to take on heavy foot traffic, which means certain types of footwear may damage the roof. Despite the relative flatness of such roofing, high winds and the risks of slipping (TPO can be slippery when wet) are safety concerns that professionals are prepared for.

What goes under a TPO roof?

What is the minimum slope for a TPO roof?

Thermoplastic single-ply roofing systems are plastic sheets (PVC, TPO, CSPE) that are welded together with hot air. This creates a shingle sheet that provides the weather protection for the building. Both the Thermoset and the Thermoplastic must be installed at a minimum one- fourth-inch-per-twelve-inch slope.
