Expert Verdict — Reviewed by the SuperArbor Pro Desk

Deck-level penetrations are the most leak-prone points on a rail-mounted solar job, so size the flashing set to the actual post and deck detail before ordering. Order one set per post and stage them with the PS45 hardware so flashing goes on as each post is set. Keep the larger piece on the water-shedding side of the penetration.

Follow the manufacturer's installation instructions and local roofing code for post penetrations, and seal per the waterproofing method required for your roof covering.


Order the SnapNrack PS45 Deck Level Flashing Set for watertight post penetrations on your next solar install.
