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 is a TPO roof attached?

The TPO membrane can be attached to the cover board with a bonding adhesive or mechanically fastened. When the membrane is rolled out, the contractor then returns and uses a hot-air gun to hot air weld the seams together.

Is TPO fully adhered?

Sure- Weld TPO membrane sheets are fully adhered to the insulation or substrate with Carlisle's Sure-Weld TPO Bonding Adhesive. Adjoining sheets are hot-air welded.

What do you put under TPO roofing?

Can TPO go directly 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.

TPO Glue Down

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.

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.

Can I walk on TPO?

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.

What is the life expectancy of a TPO roof?

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.

What means fully adhered?

1 : to hold fast or stick by or as if by gluing, suction, grasping, or fusing The stamp failed to adhere to the envelope. 2 : to give support or maintain loyalty adhere to traditional values. 3 : to bind oneself to observance adhere to the rules.

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.

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.

Is a TPO roof 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.

Is TPO better than EPDM?

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

What type of roofing is best for a low pitch roof?

Rubber roofs are a top choice for flat or low pitched roofing as it adheres to the roofing materials below it and, when installed correctly, provides a watertight seal to the elements. Choosing the best low slope roof materials often comes down to weighing the pros and cons based on your home and your needs.

What is the lowest pitch a roof can have?

The minimum roof pitch for shingles is a 2:12 pitch.

If your roof is less than 2 vertical units (inches or feet) up for every 12 horizontal units out, it's considered low slope.

Can I use lap sealant on TPO roof?

If it is a solid color all the way through the membrane, or if it has a fleece backing, it is TPO. If your TPO has a fleece backing then Lap Sealant will probably be the right choice. But if your TPO does not have a fleece backing then Dicor Ultra Sealant System should be used.

How can you tell the difference between PVC and TPO roofs?

Off the rack, no you cannot tell the difference visually. You can 'feel' a difference- PVC feeling more waxy, and feeling more pliable then TPO (unaged anyway…) PVC also has a distinct 'PVC Smell' to it.

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.

Which is better TPO or PVC roofing?

TPO is a less expensive membrane then PVC. If budget is a concern, TPO membrane might be the best choice. TPO also has superior weathering and is slightly better at being tear and break resistant than PVC.

What does fully adhered roof mean?

Aesthetics and Sheet Flutter: Fully adhered systems provide a "tight-looking" roof because the membrane is fully bonded to the substrate beneath it. In mechanically attached systems, the membrane is only fastened in seam areas, allowing the rest of the sheet to flutter in the wind.
