Browse Forums Owner Builder Forum 1 Sep 28, 2010 3:18 pm Hi guys, just wandering if there's anyone out there that could give me the difference in pricing of materials ONLY for a conventionally pitched roof VS cost of prefab trusses. So supply only... I am still trying to rough-cost everything and don't have the plans yet to get firm quotes. Thanks very much in advance. Re: Conventionally pitched VS truss roof? Chippies, anyone?? 2Sep 28, 2010 9:31 pm I can't comment on the price differential but I was very pleasantly surprised by the cost of our prefab trusses. They were a very small percentage of our overall timber and carpentry costs (less than 10%) and time wise they are fantastic as they go up in a flash We ended up going this way for our pitched roof verandah too as it is such an affordable way to build. Let me know if further detail would help. Re: Conventionally pitched VS truss roof? Chippies, anyone?? 3Sep 29, 2010 6:43 am Hi tomandkylie, Thanks very much for the input...Yeah if you could tell me the area of your roof, colorbond/tiles etc.. and how much the trusses actually cost, I would greatly appreciate it. Thanks heaps Re: Conventionally pitched VS truss roof? Chippies, anyone?? 4Oct 02, 2010 12:21 am Hi Dinko, I was hoping I had some plans to attach but I'm using a different laptop than the one I was using when we started building and have only transferred the current documents across. To give you a rough idea our extension is approx 9m long x 12m wide but has been designed to be very simple and have a simple roof line. It is basically designed around a rectangle and all the trusses were basically the same (ie they don't taper down at the sides we have used fibreboard cladding in two sides). I can't remember how many they were but given that they span around 100sqm of area i was surprised when they only cost us $1780. Carpentry labour was seperate but they pretty much all went up in one day so I guess it's one day's labour for two chippies. We have gone for a colorbond roof and this has cost us $6000 including gutters and downpipes. I hope this helps you? Let me know if you need anything else. All the best, Kylie Re: Conventionally pitched VS truss roof? Chippies, anyone?? 5Oct 02, 2010 12:28 am I'd be interesting in knowing this too. I know that trusses are popular now but if you want to use the space then they are a bit in the way. Our house is the old 90 year old method but our garage was trussed. The trusses I think are a nuisance, but we still manage to store a good assortment of junk in the garage roof (separate building) I'd be interested to know the cost all the same - especially the labour cost Re: Conventionally pitched VS truss roof? Chippies, anyone?? 6Oct 02, 2010 6:20 pm Having just built our frame not too long ago and as it is a rather large one at that, our entire frame was around $28k. the roof was around the $13k mark. The trusses spanned across 13m unsupported. If I were to use a conventional method of pitching the roof I would have had to have a supporting wall some where in the plan, if not two. The labour cost would have seriously blown the budget too. A normal size house could in theory be erected and roof trusses pitched in around two days. With a cut roof you could expect to increase the time frame to maybe two to three days just for the roof. On another note, I haven't met too many chippys here that could or want to pitch a cut roof. Without seeing some plans it would be very unfair to even consider suggesting a cost for comparison either, sorry if this isn't what you wanted to hear Dinko. Good luck Dirk Re: Conventionally pitched VS truss roof? Chippies, anyone?? 7Oct 02, 2010 10:14 pm Thanks very much for all the replies guys. I actually engaged a drafty to do our working drawings yesterday, and spoke to him about prefab frames and trusses VS doing it myself...It seems a no brainer really as the fabrication, as he suggested, is only a little extra on top of what the materials would cost. Anyway, I will learn the exact costs in a couple of weeks when we've got the plans ready and are able to obtain precise quotes. Also have decided on colorbond roof (vs shingles). Light weight roofing material like colorbond should save a bit on the cost of trusses too. Dirk, was that 28K and 13K including labor to erect them or just the prefabrication? It does seem like a big house with trusses spanning 13m, but if frame and trusses work out more than about 20K(supply only) for my house (about 28 sq) I'll be unpleasantly surprised Re: Conventionally pitched VS truss roof?

All the best, Kylie Thanks heaps Kylie, If you're in Melbourne, I wouldn't mind knowing who you got the trusses through, because it does seem pretty affordable indeed.If you could PM me the details I'd greatly appreciate it..Our roof won't be too complicated either and lightweight colorbond should help bring the cost down as well.

If you're in Melbourne I can recommend our prefab company and also a roof plumber who was very good too? Re: Conventionally pitched VS truss roof? Chippies, anyone?? 11Oct 20, 2010 11:39 pm I would think the trusses pre fab would be considerably cheaper than on site conventional. I doubt many chippies are doing roofs that are not pre fab. However I just bought my roof frame, went with steel over timber (long story). But due to an unusual roof design the cost for timber trusses was considerable. Materials accounted for well under 50% of total costs. Good Luck Pulpo Re: Conventionally pitched VS truss roof? Chippies, anyone?? 12Oct 21, 2010 12:22 am In WA stick roof construction is still the most common. Roofing carpenters are there own little sub-trade. Trusses (steel and timber) are slowly becoming more popular. In commercial work I've done plenty of trusses but in the housing side it is still mainly pitched stick roofs. My estimation price for pitched roof was $68m2. That includes supply and install including fascia and eaves. I'm pretty sure I can get cheaper than that. What sort of m2 rate do trusses work out at supplied and installed?
