The TPO membrane roof was completed this past week.  Overall, its a 100% improvement over the old roof, and I hope it will last until our daughter gets through college (with some maintenance).

I paid close attention to the install method out of curiosity, since it seems like there are at least 3 choices out there.
1.  'fully-adhered' - the TPO membrane is glued to the substrate
2. 'mechanically-fastened' - the membrane is fastened to the roof with circular metal plates with screws through them (like huge washer)
3. 'RhinoBond system' - relatively new idea where an electro-magentic induction 'welder' heats up the metal fastener plate *through* the membrane, and the membrane sticks to the plate with the aid of a weighted magnet to help the weld set (magnet top - TPO middle - hot fastener bottom).  The advantage of this is you can put the fasteners anywhere under the TPO, use less fasteners, and you don't need to create a hole in the membrane.
