Step 7: Install Top Flashings
Remove the plastic film covering from all top flashing components before installing them. There are 7
substeps to be followed in sequence to install the top flashings:
Step 7a: Install the inner Top Flashings…
The inner top flashing snaps onto the top edge of the solar
module assembly as shown in Figure 54. Verify that every tab is engaged by pulling back on
the inner top flashing. Install one for each solar module assembly in the top row.
Step 7b: Install the Top Flashing Supports and position the DynoBond™ Clips…
Place top flashing
supports at the corners of the array and at every module-to-module joint. It is important to
place the corner top flashing support as shown in Figure 56 (next page). This step would allow
proper placement of the top corner flashing later on. In high snow load areas, additional
supports may be required. The supports also serve as a water trough between top flashing
butt-joints. Therefore, it is important that the supports be centered to the module overlap.
The support should be fastened with two standard roofing nails. These roofing nails should
be attached only through the flat portion of the top flashing support within 1" of the edge as
shown in Figure 55 (next page). Position the corner top flashing support at the corner of the
solar array as shown in Figure 55 (next page). Ensure proper wire management underneath
these supports.
