Browse Forums Renovation + Home Improvement 1 Aug 06, 2013 10:16 am When I had the deck built, the builder did not quote for putting the roof on. There is a metal frame up already so the extra quote I obtained from the builder is to put colorbond sheets over the frame. Not a proper ceiling, just straight colourbond sheets screwed on. He's come back today with a quote that I think sounds expensive but I'm unsure. Given that straight colourbond sheets are around $12/m and given that there is a requirement for one gutter (only) and just one downpipe, and given he's told me he can put it up in a day, where is the $3300 coming from? Would it be worth obtaining another quote?

You could be on an isolated property all we know and regulations can also differ from State to State. Giving a few dimensions, slope and other important information helps. Were you expecting the original quote to include the roof? If so, why wasn't it noticed that the roof was not included. If it needs guttering and a downpipe, then the roof is obviously not going to be sloped back to the house gutter which is good because most are. Having it done to compliance will avoid overflows and additional rectification expenses later on. This latest quote sounds like it lacks detail; for example, in some States a qualified roof plumber is required to do the guttering and downpipe. The downpipe will need to be trenched over to the stormwater and this takes time and a plumber's time is money. If the plumber is there for let's say 5 hours, his labour PLUS call out fee could be $700 alone PLUS material costs. It is always a worry to hear that roof drainage is being added after the decking has been done as trenching to the stormwater will then generally involve doglegging around the deck. This also usually involves sacrificing the best downpipe positioning. If the 'builder' is going to do the plumbing himself and you live in a State where a plumber is required, then the work is illegal. The 'builder' would be looking at possibly $650 or more for his day's work PLUS material costs. His time could/would include the time taken to pick up the materials. The $3,300 quote would (most likely) also include $300 GST. My ballpark suppositions do not include GST etc. You should always get more than one quote but be very clear about what is actually being quoted on. I see large numbers of roofed outdoor areas that are drained back into the house gutter. The home owners are to blame when they choose the lowest quote without bothering to find out a few basics. The installers know the regulations but many will ignore them in order to provide the cheapest quote. Once you hand the money over to these characters, forget about seeing them again. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Deck roof cost?? 4Aug 06, 2013 10:56 pm Hi When I resheeted my skillion roof, it cost me ~$2000 in mateirals for just over 40m2 of zincalume sheets, 27m2 of polycarbonate sheeting in the same profile, the flashing and guttering. I threw it up with a plumber mate so including his rate ended up being $2800ish. hth Re: Deck roof cost?? 5Aug 07, 2013 5:23 pm Thanks very much for the responses. There was a lack of detail in my original post and I should address that- I'm in Sydney and within easy distance of most builders. The roof wasn't included initially because when the initial quote was done, we weren't sure what fire rating council was going to give the area. We thought it would be high (ish) which is why the entire frame has been done in steel (so that's sorted) but the roof was a bit unknown. The design is all approved through council so no worries there. The builder will not do the plumbing work. I have checked where it will come down and it will land almost exactly over the top of an outlet- so you're right that a plumber will need to come out and connect it to existing stormwater. This will add to cost- I suppose I was thinking maybe a few hours of plumber time at most- not a whole day's worth - will it really take this long to run a single down pipe? The roof is approximately 28 metres squared. It slopes away from the house and hence the extra downpipe on one end. So from the above, it's sounding like it is reasonable? I suspect noone else is going to want to do this job anyway- it's too small.... May just have to suck it up and pay.

This will add to cost- I suppose I was thinking maybe a few hours of plumber time at most- not a whole day's worth - will it really take this long to run a single down pipe? I was thinking of the usual scenario where the stormwater is parallel with the house and trenching around the deck would be required. This takes time but you are lucky here. Connecting a new downpipe is usually $180-250 as a standard install but the plumber also has to put the guttering up. You never know how a plumber will charge (quote), for example, it is unreasonable to expect them to order and pick up the material in their own time but some really milk the fact while others might absorb it in the call out. Many plumbers also head straight to Reece but their prices are very high. All things considered, you could expect the plumber to probably charge 4 hours max for what you describe. I have heard of some plumbers charging as little as $80 ph but a call out of $80 plus $30 per 1/4 hr is common. We have had a lot of plumbers who use to do commercial work come back into the domestic market because of the downturn and there is less work around now. Small jobs are more sought after than they were a couple of years ago and it is still good money. The builder is most probably also adding his own margin for the plumber's costs (single invoice), after all, he needs to organise the plumber and allow for cost overruns etc. If you get other quotes, it would be worthwhile to separate the roof and the plumbing. If you have a guttering business near to your area, it would be worthwhile calling them rather than another plumber. It is always worthwhile to try to save money provided you don't sacrifice quality and I think that you can. Good luck with everything. 3in1 Supadiverta.
