Can you repair a TPO roof?

If you're dealing with a TPO roof that failed before its time, a solution like a Fluid Applied Reinforced Roof (FARR) can help repair and even restore your system. It provides a fully adhered continuous surface with no seams, improving the TPO's waterproofness and protecting your interior building systems.

Are PVC and TPO compatible?

Also, unlike TPO and EPDM, PVC is not compatible with a lot of peel and stick or self adhered patching products. As a result, a white EPDM or TPO self adhered patch will typically not adhere properly to a PVC membrane. As a rule of thumb, the only way to patch or flash to a PVC roof is to weld it with compatible PVC.

Can you weld TPO to metal?

TPO membrane may be welded directly to the coated metal edging, eliminating the need to strip in the metal with a separate piece of membrane.

What kind of glue do you use for TPO?

EverGuard^® TPO Low VOC Bonding Adhesive is a contact-type bonding adhesive specially designed for bonding smooth back TPO single-ply roofing membranes and flashings to various roofing substrates.

Why do TPO roofs leak?

Water can enter a TPO roof through the seams

Over time, this chemical bond can degrade. Also, there might've been issues with the initial installation. When the seams were heat-welded together, maybe the contractor used too much heat, this would result in a burn which can leave pinholes in the membrane.

What temp does TPO melt?

Please utilize our Technical Service Department for more detailed information. High Temperature Resistance Polypropylenes relatively high melting point of 335°F allows continued use at temperatures up to 220°F with the material softening at 235°F.

What 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.

Can you glue EPDM to TPO?

Yes. Recovering with TPO is a great option for a building with an aging EPDM roofing system. It's easy.

Can you install TPO over 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.

Can you stick EPDM to EPDM?

Overlap the two rubber membranes by 75mm (3inches)

Overlap the two rubber membrane sheets to be joined by 75mm (3inches). It is common on long runs to overlap the two sheets by more than 3" and then cut back the top sheet of rubber membrane once the splice tape has been stuck to the bottom sheet.

What is TPO roofing?

TPO roofing is a relatively inexpensive rubber roofing material that's most often used on commercial buildings. TPO stands for Thermoplastic Polyolefin; it's made primarily from recycled rubber, and sold in rolls that are held together by seams that are “glued” together using heat.

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.

Is TPO fire rated?

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.

Why is my flat roof cracking?

This can be caused due to water, debris or long term exposure to the sun. The cracking will eventually split and develop further if left unrepaired, meaning that water can get into the roofing and cause leaking, moisture and more damage.
