Project #156 | Roof Deck Renovation – Washington, DC

PROJECT: Roof Deck Renovation, Washington, DC

PROBLEM

This disaster roof deck had ongoing leaking issues from day one. The trial and error method of waterproofing with various products was frustrating and expensive.

When last addressed, the leaky concrete deck was coated with an asphaltic tar (pitch) and covered with green outdoor carpeting. The deck was not level, had ponding water issues and was quite the eye-sore.

The owners of the home wanted an attractive surface that would once-and-for-all provide reliable waterproofing they could depend on.

DURADEK SOLUTION

Duradek was selected for this deck renovation because of its roof grade waterproof protection and its ability to be installed on wood or concrete substrates. Additionally, it could provide the attractive surface the home owners were looking for and would require no ongoing maintenance.

A 1/2 inch cement board was installed over a mortar base to provide the prepared substrate for the Duradek membrane. This allowed the deck to be leveled and sloped to the proper grade to the existing through wall drains and ensure the building envelope was protected.

JOB NOTES

Decks over structures are great! They add valuable square footage, which is especially valuable in congested city living. This 50 year old structure had leaked from the time it was built. The roof deck was replaced with different materials over the years 4-5 times. Nothing worked…until Duradek.
