We want to deck a flat roof; but the water is collecting in the middle. Need expert decking advice!?
Aug 26, 2006 by phoenixbrighton | Posted in Do It Yourself (DIY)
we have a flat kitchen roof which we want to deck. Problem is water collects in the middle. What kind/style/method/mannar of decking do we need to ensure the decking drains to the side (rather than water collecting in the middle of the decking). Please make your answer as detailed as possible!! Many thanks everyone!!
We also recentled had the flat roof re-tarred so no water is leaking into the room below. Basically a puddle forms in the same place each time it rains.
The style and decking is not the issue . The flat roof is the problem because it has either sunk in the middle on the joists or wasn't laid properly in the first place. Flat roofing is the easiest form of roofing there is but that doesn't help you. If I were you I would renew the roof or a cheaper option is to get a pre moulded fibre glass "cover" for the roof which will direct the water to where its required. I have tried to find a mouldings company for you but without knowing where abouts you are its pointless. To deck the roof after you will have to fix it to the exterior walls first as any pressure on the roof ie nails or fixings will puncture the roof and then "slat" the holding timbers from the exterior uprights and then deck from there.

Sounds like the roof needs sorting before you put anything on top of it.

Let's see. Maybe you could put drainpipes that would go from the middle to the sides, and are tilted a bit.
Basically, they run right through the roof. The ends that would direct the water are the same level with the roof, and the ends that spit water out are on a lower level; they go under the roof.

John H says that if the water is collecting in the middle the surface under the roofing felt has failed and will need to be checked out before you add more weight, try to avoid walking on it till it has been checked by a good roofer, sorry but it will not get batter by avoiding the problem or patching it and covering it with decking.
If the roof is more than 10 years old it will be past its best and could fail in a heavy storm and cost you thousands if you take shortcuts

Build up the low area with Insulated Sheeting, they make it for that purpose-and even comes tapered , draw a String line across the roof, see how deep the low spot is, then use Sheeting to even it out- its not heavy so weight should not be a problem.
You should look below in the Kitchen and make sure there is no sag in the cieling- if so you need Framing support.

All decking should bbe laid with a slight fall so that rainwater doesn't collect but flows off.(e.g. 1 side is25mm higher over 3 metres). If the decking is already laid, you can drill a few small holes(3mm) where the water is pooling, these holes will be so small that you'd have to look for them to see them, but will be effective for drainage.

Careful !! you already have a serious problem with your roof because there is insufficient fall to keep the rain from puddling. Secondly the roof joists will have been sized to support the roof structure and not pedestrians. Better go back to square one and have a structural engineer run his eye over it and advise you

why decking,tile it with quarry tiles and create a run off at the same time.check the joist size,6*2" will be OK for a 3m span,8*2" for up to 4.2m span.

If your flat roof was leaking, the felt should have been stripped, the decking below (boards) checked and if additional weight is to be loaded- in the form of modern timber decking, planters etc, the joists should be strengthened/ increased. If the fall was not sufficient to shed rainwater into the gutters, firring pieces (long wedges) should first be fixed onto the joists before boarding over with either 18mm Sterling OSB3 of plywood boards. 3 layers of fully cross bonded high tensile felt, should then be applied, preferably with hot blown bitumen, solar reflective paint should be applied to cut UV breakdown of the bitumen. If the flat roof is to be used as a recreation area, promenade tiles should be applied for weathering/ fire safety along with balcony rails to sides for fall arrest.

Which is better when installing deck: use decking nails with grooves or screw?
Aug 29, 2007 by IndiaInvester | Posted in Do It Yourself (DIY)
I use screws for everything now days, they hold better.
You will most likely have to drill pilot holes in the deck boards but not the joist, to get a good tight fit.

i have a deck but need to put new decking on as i want to know if there is a formula?
Jan 29, 2008 by Allan G | Posted in Do It Yourself (DIY)
for how much timber to buy, my deck is 10.5m wide by 8.4m long, and i am looking at 100mm by 40mm timber
Length times Width will give you the square meters [88.2 square meters], plus add 10 % for waste. In your case I would get 100 square meters.
Find out the coverage on the decking you are buying [there are different widths available] and include the spacing between deck boards.
100mm x 40mm =4000 sq mm. Convert to Square meters [4?] and this will give you the coverage of each piece of decking. Divide 100 sq m by 4 sq m and you get 25. This should be the number of pieces you need to get, if my math is correct.
After you have the total amount of coverage, get lengths that work out depending on your joist spacing so you have little waste.

Can trex deck be covered with ceramic tile?
Feb 07, 2008 by spatterso | Posted in Decorating & Remodeling
I am looking at placing ceramic tile on an 8' x 12' 2nd story outdoor deck. Deck floor is composed of trex planks over wooden joists. Can this be done. If so, what is the best way to do this. My intuition is to lay down Hardi-backer floor, then tile over after laying flash. Any reason why this wouldn't work?
My concern is if the trex would expand/contract, or if there are additional concerns that I'm not seeing. I am a novice here.
I would agree that putting ceramic tile over a Trex deck would be a mistake and you would probably have to eventually tear it all out. The key to laying tile is the underlayment. It needs to be flat and solid. In my opinion, Trex's characteristic of wanting to expand/contract would cause problems with the tile. Even with Hardi board screwed down to the decking, you will not change this expansion/contraction. You might affect the direction. Trex naturally moves in a horizontal direction. With the addition of Hardi board it may change that movement in a vertical direction, thereby pushing the decking upward and cracking the tile.
