What to Do

[TheDocta72]

Hi all

New to these forums and have already found them to be very informative and useful resource.

Anyway I have just built a covered deck with a gable roof raised 2.2m off the ground on the back of my house. Its 8mx6m and and am using the underneath area for a workshop and new laundry/toilet/shower area. I have used yellow tongue as a flooring base and have covered it with a bitumin membrane. I now plan to lay some form of timber flooring over the top. I have been looking at all sorts of solutions including recycled polycarb fake timber (yes I know "tacky") but it has a UV rating and is very resiliant to outdoor conditions. As I have french doors leading out from my lounge that already has a polished H/W timber floor I originally wanted to lay a H/W T&G floor over the yellow tongue. Can any one see any potential issues with doing this, or suggest a better method or alternative.

Comments greatly appreciated.

Cheers

Docta

G'day.
Is the deck weather proof?
If so, Glue and nail to the Y/Tongue in the usual manner.

I've worked on a few old terrace houses and it's quite common for them to have hardwood floorboards on their covered verandas. Of course they look a bit tired and rotten if they're not maintained properly, and they're often laid on a bit of a fall to help stop ponding, and to shed any large amounts of water that lands on them.
I'd imagine that a lot of 'Queenslander' type houses would have floorboards rather than decking on their wrap around verandas, but I haven't worked north of the border so I'm not too sure about that one.

edit : - A quick google image search brought up this example of floorboards used on a verandah.

Thanks for the feedback Guys.

Here are some pics to better understand my situation




The gable ends will be finished with laserlight so as you can see the only real drama i can see is the end facing the pool between the top of the balustrade and the top bearer.





So Technically its not completly waterproof. Im concerned that the timber will swell if any water sits on the deck for any length of time. I have thought of getting a cafe blind (the see through plastic roll up ones) to give me a little more protection. Any Ideas??

That eaves overhang looks a bit overspanned for a 90X45. I'd guess it's about a metre scaling off your photo. It won't go anywhere though.

What I'd be doing is putting a dutch gable on it. You could still do it now without too much trouble but you'd have to fork out a few more bucks for the gear. It would look really sexy and give you the same protection as you've got on the sides. I'll do a quick sketch of what I mean if you'd like.

edit : - I just noticed that it's only the end rafter that's a 90X45, so you're alright after all. My mistake.

Pawnhead,

That would be great mate if its not too much trouble.

Cheers

No worries. Give me a few minutes and I'll sketch something up showing how you could do it with what you've got there (if you're clever enough to set it up right)

It would look like the gable on this garage, and this is how I'd set it up going of your photos.

It's a bit of extra work, more beams and rafters and a couple of short hips, but it would look really good from inside and out, and would give the same protection as the sides. The beam you've got their just as a collar tie at the moment, might not be strong enough over that span. I'm guessing that it's about 3.6m, but you could put a cable truss under it and it wouldn't look too bad. Hang a couple of plants of it and you'd think it was installed for just that purpose .

On that gable you should be ok with the timber already being used, the spacing are at 450 and you are using a fascia beam to even the load out, its also colourbond roofing not tiles or anything, there is also no guttering from what i can see so there isnt alot of live load on the edge of the timber when raining hard, it will just drain off straight away.

The only thing i would be worried is if the wind comes up from underneath and blows the bastered right off its heels!, what are you using for tie downs?

Also be sure not to walk on it alot because you have no webbing hehe.

Hope this helps.
