Modified Bitumen Roofing Materials, Choices, Costs, Life Expectancy, Characteristics
Modified Bitumen Roof Wear From Walking-on Traffic
At above/ left we can see that in less than a year there is some granule loss and wear from foot traffic, especially where people step on the modified bitumen roof membrane as exiting and entering the door into the building.
While light, careful walking on a modified bitumen roof may be acceptable for the purpose of inspection or maintenance, on a balcony where regular walking is anticipated, the roof will not wear well.
Inadequately Heated Modified Bitumen Roof Seams
Second, in the same photograph we don't see any melted runout at the heated, lapped roofing seam. It is possible that this seam was inadequately torched or heated during installation. Elsewhere on the roof we noticed granule loss at wrinkles in the roofing membrane, perhaps caused by foot traffic over the raised edges of the wrinkles. (Continued)
However, torch down roof pros and cons allows you to eliminate many common issues in flat roofing or low-slope roofing materials. These include high possibility of leakage and faster wear and tear if you compare them with other roofing installations.

Asphalt melted to 400 degrees, then spread between layers. Torch flame applied to bottom of sheet, which melts it to previous ply Method of Installation 1. Current Modified Bitumen sheet is laid over previously installed insulation or ply
2. Backing paper is peeled off.
3. Modified Bitumen is laid back over previous layer and rolled in.1. Liquid adhesives are rolled over top of previously installed insulation or ply.

It is important to take note of this: you or an in-house team cannot conduct torch down roofing pros and cons on your own. In Texas and other states in America, roofers must have sufficient licensure and training to conduct torch down roofing. Fire is a huge safety hazard. In fact, the article above stated that torch down roofing pros and cons is a possible fire hazard even after installation.
Therefore, only work with professionals. Make sure they comply with the MRCA's Certified Roofing Torch Applicator training program and licensure. Know more about it here.
