The two most critical areas of a flat roof are the flashing and transition details. Part of day 2 would entail the connection of the roof to the massive brick chimney. Previously the roof was just draped up to brick.
Looking the other way, the crew is busy setting plywood over the insulated area. After the 3/4" T&G plywood is installed, 1" polyisocyanurate insulation board is mechanically fastened to the plywood deck before the new EPDM is glued to the insulation board.
A view of the critical transition of the 'flat' roof over our kitchen to the sloped roof. You can see many things going on in this photo. The old fascia cover peeled away reveals the existing redwood fascia with the existing membrane roof draped up to a termination bar fastened to the fascia. Needless to say, a very hideous condition.
The insulation installation is kind of a pain as it has to be run under the purlins between the 2x10 joists. On top of that an airspace has to be left above the batt and under the purlins to allow an airspace to keep the roof ventilated. The roofers are doing a great job making sure there are no gaps. The relief on my conscious almost is making me look forward to winter heating, almost.
Day 2 work completion to the left. I'm only able to stop by to check out and photograph the work at my lunch break and at the end of the day. It's impressive to see what can get done by a working crew in 4 hours. At this point we have about 18' of the sloped roof mostly complete end to end. The flashing and painting won't go down for awhile.
To the left, the new rubber flashing condition at the chimney. This looks super clean compared to the previous debacle. Addition splice layers double up the strength and durability of this connection. Note the new perimeter dam of the roof edge. After perimeter flashing is installed, this will keep the roof from overflowing on the remediated fascia.
