Case History #159: Roof Deck Rescue in Atlanta, GA


PROJECT

Roof Deck Rescue - Leaky Roof Deck near Atlanta, GA.

When a deck is also a roof, reliable waterproofing is critical.

PROBLEM

The main advantage of roof decks is that you get double the livable space. Outdoor living space above and additional dry living space below...but without proper waterproofing all that real estate is at a disadvantage. This tile deck was leaking into the lower level of the home but the homeowner was not sure what to do to solve the problem. They had tried a variety of products to stop the leaking including sealers, caulk and finely tarps. It was when the homeowner found an area that was soft and spongy that he realized he needed a professional, so he called Duradek of Georgia.

It was evident that the leaking had caused damage to the subfloor and would potentially develop into rotting wood.

Failed Tile Deck
Tile is not waterproof and tile decks will always eventually
leak if the waterproofing has not been addressed.

After a detailed inspection of the existing deck, it was clear the tile was originally installed incorrectly with little or no underlayment for waterproofing. In addition, cracked grout lines allowed water to penetrate to the plywood surface finding its way to the seams and the underside of the deck.

Once water has made its way below the tiles,
the substrate is vulnerable to rot.

DURADEK SOLUTION

Duradek of Georgia knew exactly how to fix the problem. They gave the homeowners a full presentation of the Duradek / Tiledek options for them to consider. Still unsure which option was best for them and their home, they went to see an existing Duradek installation in a nearby suburb.

Once they saw the simplicity of Duradek vinyl membrane waterproofing the choice was easy. With the owners' experience with their current tile deck, they chose to go with the Duradek solution. They were impressed with the wide selection of colors and like the idea of a minimal maintenance deck that requires no ongoing maintenance...only occasional cleaning.

After removing the old deck materials and laying fresh untreated plywood, Duradek Ultra Cork Macchiato was installed. The homeowners are very happy with the way the new deck looks and the advantage of virtually no maintenance.

JOB NOTES

Atlanta, Georgia had experienced an exceptionally cold winter that year with three days below freezing. It is that freeze / thaw cycle that can stress exterior tiles and cause cracking.

When the deck was demoed, it was revealed that the substructure was completely rotted out. New wood joists and 3/4" plywood were installed and sloped for better water management. Since  the entire deck was surrounded by a parapet, PVC coated metal was used to make custom scuppers for drainage.

Duradek Case History #158 - Urban Luxury With Roof Decks in Salt Lake City, UT


PROBLEM

These luxury downtown loft style condominiums' plans included roof decks but the project got off to a rocky start when it was put on hold for about 3 years due to financial issues after Phase 1.

The 1st Phase roof decks had been completed with a bad plan and poor installation of an underlayment below composite boards. They were already showing signs of waterproofing failure before the next Phase even started.

Roof Deck Project
The first phase roof deck had disappointing results
from a poor membrane and composite boards.

With two Phases left to complete, the new developer had to be confident in the product and the installation techniques for these high-profile roof decks.

DURADEK SOLUTION

The project developer, Clearwater Homes, contacted Duradek of Utah who was able to provide the ideal solution for these new penthouse roof decks - Duradek Ultra Supreme Granite Chip.

Installed by trained and authorized professionals that are skilled in the specific details that roof deck waterproofing requires, Duradek provides long lasting waterproofing peace of mind with a 10-year waterproofing warranty.

The new condo owners get a beautiful. low maintenance roof deck that they can enjoy for years without the need for ongoing maintenance...and the project developer has some fast-selling, worry-free roof deck units.

roofing membrane and walking surface in one.

JOB NOTES

Roof Decks are a fantastic value added feature that developers can use to increase profit and demand.

The Broadway Park Loft towers' units that had roof decks sold out rapidly and the developer now has a long waiting list for the next project. Furthermore, the inclusion of roof decks on the top floor units provided additional profit of $133 per sq. ft. on a 300 sq. ft. roof deck!

On an architectural tour conducted by the Construction Specifications Institute - Salt Lake City Chapter, one architect exclaimed, "I expected to see a roof. What I saw was a floor."
