Hi all, I have a 1970s house with Decramatic roof tiles that need rechipping. I just rang for a quote and got told I need to get the tiles tested for asbestos?. I have had a few freinds that have had similar roofs rechipped and sprayed but didn't require an asbestos check. Has anyone come across this before is it a new legal requirement?

Laws around working with asbestos got tightened in 2016, So I'm guessing they want to know there is none there before they are prepared to do the work......

With the Decramatic tiles the asbestos is in the glue that holds down the chip. There was a article in the ranz magazine recently about it.

Hi Rick , thank you just looking on their site, do you have to be a member to view magazines?, if it’s the glue do I still take a tile sample for testing?

If it is asbestos, my recommendation would be a reroof as after November next year your house will have to have a scaffold shrink wrapped tent assembled around and over it before anyone will be legally able to undertake any work on it which will cost a lot.

Have a read through the following, you currently have the choice of waiting until the neighbours or people in the area arnt home or the preferred method of isolation of the area being worked on. This is changing to having to isolate the area. The amount of reroofs happening and especially in the commercial market is crazy at the moment because of this. http://www.worksafe.govt.nz/worksafe/information-guidance/guidance-by-hazard-type/asbestos/licensing/documents-and-forms/technical-bulletin-management-removal-asbestos.pdf

This is really crazy massive costs , the suburb I live in is build 1970s,80s I would say 70% of houses have these tile types . What I have read is that its fine if careful all I need to to is respray throw some chip on. Not water blast it off which will cause damage :)

That seems an extreme approach. I can't think of anything less friable. An asbestos sheet roof just sitting there would be releasing more fibres into the neighbourhood. When the high rise building at 61 Molesworth was being demolished and asbestos was a possibility the authorities gave the go ahead subject to a water spray that literally looked piddly. Obviously small jobs are easier to overkill.

From elsewhere "Just hang fire until worksafe decides if they are going to make a exemption to the category b asbestos rules. At the moment we have to use licensed removalists and they are rorting the prices. Once given the clearance roofers will be able to remove and dispose for about half what they are charging. Should be anytime soon. ( Note that this is for 70's decramastic and Harvey tiles)"

I think the problem with rechipping is that without thorough cleaning (that you can't do) the recoat won't stick properly.
