Solar Mount Flashing

Gather materials and tools
You'll need solar flashings (appropriate type and size for your installation), roofing screws, sealant, a drill with the appropriate bit, a screwdriver, a utility knife, safety gear (including gloves and safety glasses), and a measuring tape.

Measure and mark
Measure the edges and joints of the solar panels and the areas where the flashings will be installed on the roof. Mark these locations accurately to ensure proper alignment.

Prepare the flashing material
Cut the solar flashings to the appropriate length and shape using a utility knife or metal shears. Ensure that the cuts are clean and precise to achieve a good fit.

Install base flashing
For step flashing, start from the bottom of the roof slope. Position the first piece of flashing under the bottom row of shingles and above the solar panel mounting bracket. Secure it in place with roofing screws, making sure to drive the screws through the pre-drilled holes in the flashing and into the roof deck. Seal around the screws with sealant to prevent water penetration. Continue installing step flashing pieces in a stepped pattern, overlapping each piece properly as you move up the roof slope.

Seal all joints and edges
Apply a generous amount of sealant to all joints, seams, and edges where the flashings meet the solar panels, the roof, or other flashings.

Check for proper installation
Once the flashings are installed and sealed, visually inspect the entire installation to make sure there are no gaps, loose edges, or areas where the sealant is missing. Check that the flashings are properly aligned and secured.

Final inspection
Water test: Use a hose to spray water on the installed solar panels and flashings from different angles to simulate rain. Check for any signs of water leakage inside the building or around the solar panel installation area.
