Roofing
This roof is a flat room with an un-vented cavity. The roofing system requires that the slope be built up with tapered rigid insulation and we used a TPO single-ply membrane. It is more expensive than an EPDM application, but last longer and is easier to install and comes with a longer warranty. The TPO membrane is white and reflects heat better than the old black torchdown type roof you can see on the neighbors roof in the background of the first photo. The roof cavity is filled with a combination of spray foam and batt insulation.

| 6 mil vapor barrier with minimum R-10 polyiso rigid insulation to keep that roof sheathing surface warm to mitigate condensation |

 |
| Rolls of TPO roofing that will be mechanically fastened to the rigid insulation. Seams will all be overlapped and heat welded |
 |
| All plumbing vents and roof penetrations were in place prior to roofing installation |
 |
| Top of parapet wall. TPO roofing runs up and over the parapet and will receive a sheet metal coping. |
