Is Tpo Roofing Applied With A Torch

Two of the commercial flat roof systems commonly found in the northeast are modified bitumen and thermoplastic polyolefin tpo.

Is tpo roofing applied with a torch.

A modified bitumen roofing system being applied with a blow torch modified bitumen is a single ply flat roofing option that typically is installed by rolling materials directly onto the roofing surface. It s important to note that this type of roofing is more commonly designed for flat or low sloped roofing. Torch down roofing consists of multiple modified bitumen membranes applied with a propane torch. Clearly the name was derived from the method of application by using a torch.

As we mentioned many times so far a torch roof is applied with propane and a torch. Traditionally the material had to be rolled onto the roof and then heated with a blow torch to allow adhesion. An overlapping seam is then created. This video shows the degradation of epdm rubber material due to ultraviolet ray exposure.

This layer now becomes a waterproof material that is ideal for both commercial and residential use. Contractors use the mechanically attached system when installing tpo on flat roofs. It is then heated and kicked out just like the first roll. They achieve this with fastening plates to secure the roofing material.

So maybe pvc is better for you. Mechanical installation for optimum roof security. However tpo roofing is combustable it will burn by itself whereas pvc roof will not burn if you remove the source of fire. Torch down roofs are composed of two or more layers of a modified asphalt membrane applied with an open flame torch.

Them it is important to have it coated with silver paint or aluminum asphalt paint. Torch down roofing also known as torch on roofing is one of the most common types of roofing for flat and slightly sloped roofs. Epdm vs tpo is at par with longevity with tpo having roughly the same lifespan as epdm with 22 30 years. Regardless of the type of surface preparation the tpo roofing system is still a single ply membrane that will not last as long as a two ply modified bitumen torch down rubber roof membrane system.

Although tpo is a good roofing system there are still many inconsistencies with the heat welded seams. Modified bitumen roofing has been around since the 1970s when it was developed to address ongoing issues with traditional asphalt roofs.
