Does TPO 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?

Can you put TPO directly on plywood?

TPO is a single-ply membrane that can be installed over the top of the plywood. Although there are different types of roofing material, like metal or wood shingle roofs, this type provides an alternative because it's much cheaper.

Is TPO roof glued down?

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.

How many years does a TPO roof last?

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.

Why You Need Underlayment For Your Floors

Can you walk on TPO roofing?

Flat Roof Surfaces You Can Walk On

Whether its BUR (Built-up Roofing), TPO (Thermoplastic polyolefin), Modified Bitumen, or Single Ply Roofing, your roofing professional can apply the right waterproofing membrane to make it possible to walk on.

Is a TPO roof considered a cool roof?

TPO, also known as a “Cool Roof”, is a very durable and energy-efficient roofing system. TPO roofing can reduce heating and air conditioning costs by as much as 25 – 35% once installed and completed. TPO can be used in many applications from commercial to residential flat roofs.

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.

What is TPO roofing membrane?

Thermoplastic Polyolefin is a single-ply roofing membrane that is one of the fastest-growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs.

Is TPO roofing flammable?

Single-ply roofing materials such as TPO are a sub-specialty category of roofing. This means that single-ply roofing is made using highly flammable and toxic materials. Solvents and adhesives are used to compose and install TPO roofing, which does make it flammable.

Is TPO roofing fire resistant?

TPO is ENERGY STAR rated and meets the higher standard for California's Title 24. TPO membranes are mold resistant, impact resistant, wind resistant, fire and traffic resistant.

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.

How strong is TPO roofing?

As TPO membranes have hot air welded seams, its seam strength is three times stronger than conventional rubber roofs that use tape systems. It is also about six times stronger than those with glued seams. This is very beneficial when using rooftop supports that need to be fastened to the membrane.

Is TPO better than tar and gravel?

Often times you will find that TPO is actually cheaper with many advantages whereas Tar & Gravel has more disadvantages. When it comes to environmental questions both help with UV light in that it will reflect or absorb the UV light for roof longevity.

Does TPO shrink?

TPO does not shrink over time, but PVC can and this will cause many problems on a roofing job.

What is TPO bonding adhesive?

A high strength solvent-based contact adhesive that allows bonding of Mule-Hide TPO membrane to various porous and non-porous substrates.

What is TPO primer?

A solvent-based product designed for one-step cleaning and priming of TPO surfaces to be bonded with In-Seam Tapes, Uncured Flashing Tapes, Cured Cover Tapes, and Pre-Taped membranes.

Can you paint a TPO roof?

Then, based on recommendations from a national coating and paint company in Canada, the best paint to use to paint a TPO roof is elastomeric paint. If you use a good quality elastomeric paint, then that will eliminate the need to use a surface primer first.

Is TPO a rubber roof?

The name is a bit misleading, because rather than being plastic, TPO is one of a few different types of rubber, usually a blend of polypropylene and ethylene-propylene rubber.

Is TPO compatible with asphalt?

*Note: EPDM, flexible (plasticized) polyvinyl chloride—PVC, uncured neoprene and TPO are not compatible with rubberized asphalt.

Which is better PVC or TPO?

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.
