I’m building an Asian inspired timber-frame building to house a hot tub for a client. She is requesting a flat roof that she can later build a deck and walk on, but I am thinking to save her time and money to install a DURADEK type system that can do double duty as both the roof and deck.
How hard are these systems to install? It would be laid over 2×6 T&G pine, and I would build up the indentation between boards before installing membrane. The total area is 22’x24′
Is there a company out there that will sell to me, even though I’m not on of their trained installers?
Thanks for the advice in advance!

i'm not familiar with Duradeck or whether it is safe and comfortable under bare feet, but ANY roof material will not like the movement from the multiple joints of T&G boards, so be sure to engineer it against deflection for that heavy load, and lay plywood or Advantec over the T&G to eliminate so many joints and movement

It's kinda like outside vinyl flooring. It's got good minor grip/texture.
Not sure what you are refering to by "whether it is safe"
did you mean slip resistance maybe?
It is ADA compliant for slip resistance. We have installed it on wheelchair ramps and have never heard of an issue. And in the Willamette valley of Oregon we get every kind of weather.
It is indeed comfortable on bare feet. It does get fairly warm in the sun as everything does, but on a hundred degree day in direct sunlight it is tolerable to walk across. Nothing like a concrete sidewalk would be under the same circumstances.
FYI, Duradek has been in business for over 30 years and has an excellent track record with a great warranty.
The slip resistance is what I had in mind, esp when wet.After your description I remember looking into using it once. you also confirmed my other thought about the substrate needing to be smooth.

I install Duradek, You can find allot of info at http://www.duradek.com.
Duradek can only be installed by a trained and authorized installer. It and any other like product needs to be installed over 1/2" min plywood. (not osb)
their are other products out on the market that you the end user can purchase and install but i would not recommend it for even the best do it yourselfer.
If you would like to attempt it, try your local roofing supply house, they will probably have a product for you.
IMHO Duradek is the best product out there for this type of installation. Assuming you have a competent installer in your area you will have a roof deck to do nothing to except wash and enjoy for YEARS!
I'd put down the plywood underlayment, think though carefully and make provision for where stairs and railing are going to be attached in the future, and get an installer to put down Duradeck. It's not something I am comfortable using over insulated living spaces, but for a building like this it sounds ideal.
I contacted the ABC Supply in my area and he headed me towards Dec-Tec <dec-tec.com>. I've got a leister heat weld gun, the only disadvantage I can see are the seams since it only comes in 76" rolls and I'm doing an area 22' wide. From what I can tell with the sample material, the seam strip seems like it could be a real toe stubber! I'm about ready to increase the pitch, put roll roofing on it, and a wooden deck, since the material alone for a membrane type roof/deck is $12sqft for duradeck!! I know its a good product, but for a dang hot tub enclosure (read outbuilding!) . That said, I can get 600sqft of Dectec for $3.30sqft..... Pressure treated material is pretty darn cheap around these parts as well!
Thanks for the replies/advice thus far and for those yet to come!
