Homeowner has a 30x30 walkout deck over his finished attached garage. Deck is on I-beam joists with 5/8" plywood glued and screwed. Previous contractor then added 3/8" osb and covered it in LinX truck box liner spray (or Rhino spray or a similar brand). It leaked. COntractor came back and rolled on an armourthane product. It leaked. (that is all I know about the second product) Contractor has not returned. Homeowner has tarred down tarpaper and other sheet prodcuts over leaky spots and has redone his garage ceiling (interior) twice now. Wants to replace the deck surface with a long lasting product that doesn't leak.
Challenges:
-Home is stucco with a flashing ledge on which the base of the stucco sits over the deck. This height cannot be adjusted. It is currently 3/4"-1" above the deck.
-Around the deck are 6- 10x10 stuccoed posts with no base flashing!?!
-There are three separate doors leading onto the deck and as of now the deck height is level with the TOP of the aluminum threshholds on them so it cannot go higher. If it wasn't stucco I would consider moving the doors up.
-Can't build a roof b/c i dont feel comfortable doing it w/o engineered drawings and he wont get them. (I do think a deck surface product will work.)
I will remove the existing roll on prodcut and the 3/8 OSB. Then, I am thinking of applying a rolled vinyl product like Duradek or Dek-master. However, the triangle shaped cantstrip flashing will not fit under the stucco drip sill so how to flash the vinyl to the home and posts? ANd how to flash it to the door threshholds? I don't like the idea of a bead of silicone being the only barrier to water. Any comments on the longevity of these vinyl products?
Or, perhaps I could apply a roll on product like this

I am not as familiar with these but I do like the idea of a roll on product b/c then I can roll under the existing stucco drip sill on the bottom of the wall and roll right up to and even right up the posts an inch or so b/c they have no drip flashing or bottom bead to roll under.
OR, perhaps I could put down Commercial Ice and Water on the original 5/8" (or some other product) then use 1/2" furring strips and lay a deck surface over the deck with 5/4 x5" pt bullnosed decking?? (or some other surface) Height would be a concern, esp. around the door threshholds and i am not sure how to ensure the screws that hold the decking down and the screws/nails that hold the furring strips down will be sealed. ??
I am open to other suggestions. I can post pics if someone suggests how to do this and feels that it would help them to formulate a solution or suggestion.
What do you think would work best? I operate under a "meticulous workmanship" motto. I want to do this the best way possible. (I also want to help the poor fellow out. =) He has had a leaking deck on and off for 15 years now and water leaks are so insidious. =(
Any comments are appreciated.
Thanks.
