As you may recall from a previous post, I went back to NYC just as we had finished the structural work on the roof and were finishing the installation of the planks. While the roof is now structurally sound, it's not watertight, so it's been covered with tarps in the meantime.

| Temporary tarps to keep the water out |
Today we're going to start installing the insulation and the two layers of waterproof membrane. These waterproof membranes will keep the building watertight before the slates go on, but once the slates are installed, the membranes act as back-ups for the slate in case any water makes its way in. (I've described our "Hot Deck" roofing system in detail in yesterday's post, so if you want to understand it in detail please take a look at that post.)
