Thread: Legality of DIY re-roofing

Technically it should be done by a licensed roofer or plumber. I don't know what the penalties are though. It would probably take someone to 'dob you in' to get caught too.

However don't underestimate the size of the undertaking. It's a big job and you don't want your roof off for very long at this time of the year. $18,000 actually sounds like a reasonable price if it includes removal of the old roof as well. I think the breakdown would be something like half for the roof and half for the labour.

weekends only? - - better not rain during the week heh!

I always thought that builders had to use a licensed roofer/plumber in order to do roofing, but I've never seen anything solid to suggest the home owner cant do their own work. Whether this is because its an unenforced thing or whether they can or not I'm not quite sure. I am however very interested in any answer you get, because just seacrhing google didnt bring anything up.

When I built my workshop in my backyard, I did most all the work myself but I intended to get a plumber to do the roofing (I try to do the right thing). I called many plumbers, but being an OB they are either not interested ("too busy") or put in an astronomical quote to do the work. In the end I phone the local council (who also issued the building permit) and asked if I could do it myself. The answer was yes. They stressed that they wanted to see that the downpipes are correctly connect into the storm water system.

A couple of provisos, my building was a "category 10" building (shed/workshop) - the response maybe different for a "category 1" (house); This was in Melbourne; it was sometime ago.

Beware, if you start it yourself, make sure you can finish it yourself. It will be hard and costly to call someone in to "finish it off".

I called many plumbers

Most roofing suppliers either have teams or will put you onto one.

My old man is qualified to do it but we paid a roofer (ex-employee of the old man) because of the size of the job. It took them both 3 weeks full time to do it.

Lucky I'm on good terms with the neighbour, and I don't think any plumbers live in my street.

Yes I thought the quote was about par, because it is a complicated roof.

Yes it is a big job. I plan to do the roofing in 3-4 hour lots a couple of sheets at a time. I haven't worked out how sarking fits into this plan yet.

Battens are another issue. Some say, without looking, "replace the battens". Well I've had a look and they look OK to me. Should I, regardless, just replace them?

Yes, thanks for the warning. I need more thinking cap.

Technically, you might need to get an owner-builder certificate to do a job worth $18,000. I think the cut off is different in different states, but it QLD it's 11,000.

Owner builder permit ? why would you need one of them its only replacing what is there isn't it?
Its not a new addition is it ? well maybe it is if theres no roof now !

And what license would you need to put a roof on ? As far as I know you only need a licensed plumber for the plumbing and a licensed electrician for the power the rest you can do yourself .

You need a permit to restump a house, and that is replacing what is there!

It's been a while since I took my OB course in QLD, but I think the rule was that a homeowner performing any work which normally be performed by a licensed contractor which was valued at more than 11,000 was required to get an owner builder permit. Again, this could be different in NSW, and legislation may have changed again anyway.

Of course, you need to consider how likely it is that someone who cares (council?) will actually notice your work and dob you in.

AFAIK in Victoria you need to be a licensed roof plumber to do roofing work.

ditto NSW...

In Qld, AFAIK, owner builders can do their own roof plumbing but not plumbing and drainage work.

In Vic, inspectors have been known to follow up on delivery addresses for orders, lobbing on site & requesting the plumbers name & certificate.
So its not only a case of being dobbed in by disgruntled neighbours.
You don't need a building permit if you're 'replacing' the iron. You do if you're replacing say iron with tiles or tiles with iron.
Technically you do if you replace the battens.
In some cases you may need a planning permit.

Here in the States, or at least in this state (South Carolina) any licensed contractor is authorised to replace a roof. In addition, it never needs a permit unless you're adding on. Also, any homeowner can replace his own roof at any time if he's up to the challenge.

However . . . file a claim for water damage with your insurer after a DIY job and see what kind of response you get.
