DEK Drain

With both above- and below-joist options, a flashing strip is installed at the ledger board, the membrane is then laid over the joists so that water can run towards the gutters. To prevent leakage, cap strips are installed over the membrane with each joist.  


This product uses a well, flashing tape, caulk, and includes downspouts and plastic trough sheets. The sheets are placed on the top of the joists and stapled into place, draping between them. When water falls between the deck boards, they land in the troughs and travel to downspouts at the end of the joist. In order to waterproof the ledger area, flashing tape and caulk are used, along with seams around railings and the seems between trough sheets.

Zip-UP UnderDeck

This type of deck drainage system comes in two layers.Installed perpendicular to joists in order to create a slope, pitching rails of varying widths are used. After that, the main rails are installed parallel to the joists. Finally, vinyl panels are installed that make up the ceiling. Unfortunately, with this type of deck drain, you have little to no options when it comes to the design and you won’t be able to install lighting fixtures or fans in the under deck area and it’s a bit more expensive than the options above. On the other hand, it does have a Class A Fire Rating and has passed standards for hurricane testing.


This type of deck drainage is known for being very easy to install. Interlocking galvalume metal panels are supported at either end with a perimeter guard. Dry-B-Lo comes in three different colors: light stone, dark bronze, and pearl white.
