We didn’t get any good shots of the roof actually being put on because it only took a couple of days. The flat sections of the roof actually aren’t perfectly flat. The styrofoam insulation on top of the ZIP system sheathing is cut at various slopes so the roof drains properly. Then the membrane is placed on top of that and glued down.
Before getting to the roof, the La Cantina moveable glass walls have arrived! That’s about 3,600 pounds of mostly glass. There are 6, 600 pound panels. They had a wall very similar to this installed at the showroom and they move with just a couple of fingers. The secret is the large urethane wheels they roll on. These aren’t lift and slide either, they maintain their full 160 mph wind rating wherever they are on the track.
Here are some of the styrofoam roof pieces. As you can see they are different thicknesses and if you look really closely you can see the taper in some of them. The big cardboard tubes are what the membrane was rolled up on.
These long screws are what hold the styrofoam down. At the bottom right is the “tape” used to cover seams in the membrane.
Here’s the box that the “tape” came in. The manufacturer likes to call it “Quick-Applied Uncured Flashing”.
The adhesive for the membrane comes from the factory in pre-charged metal containers that look like 5 gallon propane tanks. This is no fun to put down, it requires full protection!
