Columbus Court, by Henry Walker Homes |
In this case Duradek and Lone Star Builders Inc. who have a long history together again teamed up to provide an awesome waterproof walkable roof top deck that is bound to be a drawing feature of this home. Doing a job like this has to be done right the first time and with ascetically pleasing details.

Since the membrane is going to be fully adhered to the plywood substrate preparation is key. Any imperfections in the plywood such as knot holes are filled in. The seams where the plywood meet are also addressed so there is no line showing thorough the finished product. In the lower right hand corner the trained installer has already measured out the location of the seam and has recessed the 3/4 inch over lap. This will allow the bottom sheet to drop into the groove, the top sheet then will be aligned thus eliminating the "bump" often seen with over lapped seams. Although the seam doesn't go away completely they are more difficult to locate and will not impede the water flow.
As you see on the left a Duradek installer uses a scrapper and rubs the membrane in by hand. This provides them an opportunity to catch any debris that may have been trapped under the membrane as well as assuring the best bond possible. Here they are aligning the bottom sheet with the recessed seam.
Here installer is heat welding the recessed seams together. Basically the two sheets are melted back as one. As you can see here, the recessed seams are not even noticeable.
Roof decks are fast becoming a highly sought after feature of any new home in the Utah market. Virtually every location has a wonderful view and with the right design, like the one seen here will help to increase the builders sales and customer satisfaction.
