Deck Waterproofing Project – Cincinnati and Northern Kentucky

Deer Park Roofing designed and installed this beautiful new deck to create a covered, waterproof patio underneath.
Old Deck
This is a photo of the deck that was removed.
Water Proofing
A new deck is being installed with the goal of achieving a waterproof bottom patio with hidden gutters and downspouts.
Wood Frame
The entire deck project was designed by Deer Park Roofing, Inc.
EPDM
An .060 EPDM membrane was fully adhered to the surface of the upper deck.
Flashings
Flashings are installed to the perimeter of the membrane and along walls.
Sleepers
4″x4″ pressure treated “sleepers” are placed on TPO padding and the membrane. Fasteners are not applied through the 4×4´s and the membrane.
Fasteners
The composite decking is installed with hidden fasteners securing them to the 4×4´s. Fasteners once again do not penetrate the EPDM membrane.
Gutter and Downspout
A gutter and downspout are installed. The gutter and downspout will be concealed when the project is complete.
Finished
The underside of the deck is watertight, allowing beadboard, lights, speakers, and even a ceiling fan to be installed to the area below the deck.
