Browse Forums Outdoor Living 1 Sep 03, 2010 9:51 pm Hi everyone, Im currently in the planning stages of building a patio roof. Im not sure on what truss design is required. The width between posts (rafters) is about 4.7m. Im planning on a putting up a polycarbonate roof and maybe wood lining at a later date. I would ideally like a simple design as im going to make them myself, i cant attach a picture for some reason. I was planning on just having one beam going across the rafters 2/3rds to the top of the truss triangle if that makes sense. Any thoughts on weather the design would be sufficient or needs extra support? Im planning on using 200x50mm timber. Thanks in advance Dave Re: Patio Roof Trusses 2Sep 04, 2010 1:16 am For starters you will need to apply to council to build your patio complete with truss drawings if you are going to build it in trusses. Standards have also recently changed for trusses. My advice to you would go and find a truss builder get them to do you a roof layout, you can always install them. I wouldnt try and build them myself. Re: Patio Roof Trusses 3Sep 04, 2010 8:59 am What you are talking about sounds like a gable roof, not a trussed roof Decide if you are going to timber line now as you will need anti-con under the roofing if you are Re: Patio Roof Trusses 5Sep 04, 2010 2:05 pm Thanks for the replies. Ive already emailed our council (Rockingham WA) but they have not got back to me, im trying to get a good idea what is required so the plans get approval 1st time around. Unfortunately I cant phone or go in as im working shifts offshore. Dukekamaya, yes im planning on building a gable roof but I was under the impression that there needs to be some sort of support, not quite sure what you mean by "decide if you are going to timber line now as you will need anti-con under the roofing" The best option may be for me to have to wait and talk to my local council and get a straight answer from them... Many thanks Re: Patio Roof Trusses 6Sep 04, 2010 4:51 pm I mean if you decide to line it and there is no anti-con, the condensation that will form under the roof will drip and eventually rot the timber.

By stick build I mean conventional roof framing. Re: Patio Roof Trusses 11Sep 05, 2010 1:37 am I_BUILD No thats prefab. By stick build I mean conventional roof framing. Stick Built means built 'on site' Prefab is 'off site'. It would have taken longer and cost more not to use trusses, besides I used recycled materials, so the price was right ...free. Just to make myself clear 8x5 is in mtrs not feet. Yes the knot that missing and split on the end. Turns out it needs rectification. 6 2503 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 11072 |
