This general specification is for the installation of a membrane system used in new construction and reroofing applications over nailable deck types (e.g. plywood).
A.) Fibreglass base sheet:
This is the first layer which is nailed to the deck using Simplex Nails (nails with a large washer-like head).
B.) Torch-on base sheet:
This is the second layer. It is torched down to the fibreglass base sheet.
C.) Torch-on cap sheet:
This is the third layer. It is torched down to the torch-on base sheet, and it will have a granular surfacing as the membrane’s protection against ultra-violet light.
Bird house vents:
These vents let the air circulate through the rafters to remove moisture and heat.
A flashing which allows breather pipes for your plumbing to pass through the roof. From the ground, they appear to be a pipe sticking up through the roof.
These copper drains allow water to drain from the roof through the soffit (roof overhang) to downpipes attached to the exterior wall of the house.
These copper drains allow water to be drained from the roof to the downpipes without going through the soffit.
This is a flashing for your furnace or chimney.
All our metal flashings are made from 28-gauge metal and come prepainted with a baked-enamel finish that won’t rust!
