Under Deck Roof


Hey guys i got a call this morn from a guy who wants his new elevated deck to be sealed underneath (ceiling only no walls) to be used for parking golf carts, atvs and such. Ive never done one and dont think i have ever seen one around hear. I know ive read a thread about it here but cant find it. To those who have done it what method or brand system you use?
This is a hunting cabin so while it has to work look decent and last it does not have to be top notch high end million dollar home stuff.
One thougt i had was use taperd and treated strips then put up vinyle sofit material. Trim with alluminum or treated wood and use gutter on the low end.
Could use metal too.
What you think? Thanks.

Re: Under Deck Roof


Best Way>>> plywood over the joists,torchdown roof over the plywood with all needed flashing, .40 acq stringers laying in the direction of the flow Not screwed into the roof<<< screw the decking to the stringers Not thru the roof<<

A way that will work>>> regular metal roofing installed under the deck on tapered rips fastened to the bottom of the joists<< Al the DeckMan is a Master at this. J.

deck was just built last week so tearing it down and doing a tourch down is not an option. Besides i cant do that anyway.

Metal on the underside is what im leaning toward so any help or experience with this i will appreciate.

I think it was about the expensive hi tech stuff though.
I may end up doing that anyway just need to present the expensive and cheap options to the owner sense i dont think he really cares about first class looks on this.

That looks nice. Havent checked yet but i bet it will have to be special ordered here. Im going out tomorrow to look at the deck. If there's no post or beams in the middle i'll probably just build and upside down metal roof with corragated 26g metal.

Re: Under Deck Roof


The metal roofing under decks works well for storage area like your customer wants not high end homes that want a covered patio.

I used a new product earlier this summer on a deck. It was a rubber membrane that went under the decking between the joist, too late for that now tho. It seemed to work well, but time will tell.

I have used underdeck once with good results. Fairly easy to install also. I got mine from Menard's.

If you search on this forum for "drysnap", you'll find folks are less than pleased with that product...

Re: Under Deck Roof


That does look like a snap.
I was over there today working on two other houses on the property and took a look at the deck on my way out. It is about 750sqft in an L shape and 2 differnt levels. The guy was not there so i still dont know exactly what part if all he wants done. O and most of it is about 12' high on level ground though.

Re: Under Deck Roof


I just found my pics on this project done last year.Thought it came out nice for my first attemt at it. In the first pic you can see the spacers i made out of pvc and used 3 different length screws to get my pitch.

Re: Under Deck Roof


Roofing on the bottom looks like it would work and looks pretty decent. Steel roofing prices are down now.

Couple of questions though....where are you dumping the water, right out the end?

Why no notching in of the rim joist and why not just set the header on top of the 6x6s instead of bolting it on to the side of them? Also how are those stairs attached to the deck?

How did you hang and protect the lighting that's in the ceiling?

Re: Under Deck Roof


I thought I would get questions about that deck framing. You should have seen it before the metal. No I did not build the deck and i dont like i either. I would have notched the 6x6s, tripled the rims perpendicular to the joist and used hangers on the stair stringers. But whata yougona do?
As far as dumping the water, the roof is pitched to the middle about 2". See the gutter? If you look close you can see the receptor for a down spout on each end I havent yet done when i took pic.
I did hang the lights and they are screwed dirctly to the 26ga metal with a water tight grommet for the wire and a generous helping of silicone for added sealing. Also drilled a weap hole in the light housing just in case.They are exterior deck lights btw. The wire is direct burial 12ga.

Re: Under Deck Roof


In regards to lighting in the underdeck system could you use low voltage landscape deck lighting. It seems like it might work?

Re: Under Deck Roof


We have used them all and the best product by far out there is inside out underdeck by QE. I do not have enough post to show pics, but do a search for inside out underdecking and you will be able to find it.
