According to the 2014 2015 national roofing contractors association nrca market study most new projects in the past few years have specified a white tpo roof.
Tpo roofing membranes have been noted to have an issue of accelerated weathering when subjected to high thermal or solar loading.
In general tpo is a relatively low cost high performing roof membrane when installed the right way.
Tpo stands for thermoplastic polyolefin a single ply roofing membrane that covers the surface of the roof.
Roof bubbling is just what it sounds like spots where the rubber has lifted off the surface of the roof and formed a bubble or blister.

The most common cause of roof bubbling is poor installation of the roof.
If left untreated a blister can grow larger and allow more moisture to get in so that the problem gets worse until more extensive repairs and possible replacement is necessary unless it pops.
