Lay out the RoofScreen and determine the location for each
frame. Base Supports should be installed in a straight line if
possible, but it doesn’t have to be perfect. Frame cantilever
discussed in the previous section will allow some adjustment
during frame installation to make up for a few inches if
necessary. It is recommended to use string lines or a laser level
in vertical mode to ensure all Base Supports are in a straight
line.
Base Supports are designed to mount to structural members in
the roof. Due to the vast number of variables in field
conditions, neither hardware nor methods for making this
attachment are included in the Frame Kits. The bottom plate in
the Base Support has pre-punched holes to accommodate up
to twelve ¼” fasteners, and five 3/8” fasteners (see Figure 2).
Here are some typical methods of attachment:
•
Wood Lag Screws: (2 or 3) 3/8 x 6” lag screws installed
in the .470” holes, arranged in line with the wood
beam below.
•
Tek Screws: (4) #14 diameter self-drilling Tek screws
installed in the .313” holes, fastening into I-beam or
open web steel joist below.
•
Concrete Anchors: (2 or 4) 3/8 diameter concrete
anchors or expansion bolts with 3” to 5” embedment,
installed in the .470” holes.
•
Through-bolts: (2) 3/8 through-bolts installed in the
.470” holes.

OOFING
After all Base Supports are installed, have a qualified professional roofing contractor install the Flashings over the
Base Supports and roof them in with appropriate method for the type of roofing system being used. If hot asphalt
or a liquid applied system is being used, it is recommended to cover the threaded holes at the top of the Base
Supports with duct tape. This will prevent material from clogging the holes and making it difficult to thread the
bolts when installing Base Assemblies.
Either the roofer or RoofScreen installer should adjust the height of the Flashing Boots to account for thickness of
roofing and insulation. Flashing should terminate as closely as possible to the top of the Base Support, but not
more than ½” below.
