When done correctly they are a great addition to the home. Duradek is the way to do a roof deck right, ask David Rupp of @Home Realty. David has been instrumental in bringing this very unique design to life in one of the harshest climates in Utah.
What makes Duradek different than the other products is really very simple. They don't mess around, waterproofing is a serious business and not one to be taking shortcuts in. Duradek's walkable roof membranes meet or exceed both traffic coating and roofing approvals. That means they go through more than four times as much testing! A coating product will only be tested in four areas while Duradek goes through eighteen of them, there are very, very few products in Utah that are approved as a walkable roof system.
Over the next couple of posts here we will walk through the installation process from beginning to completion and explain the steps taken that will provide you with a waterproof deck that will last for decades. Oh yeah, the maintenance program is - Wash it off!
What I have learned was simple. There really are no standards an the most common practice was to do everything at least twice. Redundancy seemed to be a confidence builder. In reality all it would do is delay the inevitable failure. The owner was very often the person faced with the expensive repairs and there was a lot of finger pointing between contractors and trades.
