Compatibility of roofing materials

So does that mean that every time we fart our roof deteriorates.

Only if you haven't got ceiling in your house or if your working in your shed and you stink like a pig.

Bazza,

Well answered.

Lysaght produced heaps of good literature. One example is their booklet titled "Steel Roofing and Walling Installation Manual".

Do you know if there are current reprints available of any of these publications. If so I would recommend them to anone faced with a re-roofing job.

I also remenber seeing some excellent stuff on the effects of runoff from inert catchments, such as Zincalume, Colorbond and tiles, but can't locate my copy.

Here you go, download your own personal copy and the same for anyone else wanting to put up their own roof and wall cladding.

There is a loads of information on the BlueScope® Steel and Lysaght® web site including free down loads.

Also because of the fanatical heritage wankers.

OOOOhh - bit sensitive arent ya Bazzza - you still a LysaghtTM rep?
Why dont they make Z800 galv anymore just out of interest??
And you wouldnt be calling me a fanatical heritage wankerTM now would ya?
I prefer the look of galvanising and laying the sheets out from the centre out on a symmetrically shaped roof in a tiled pattern makes more sense aesthetically but when you talk to fanatical salesman wankersTM they cant understand it.

OY! Don't forget about us regular wankersTM too!!!!

Sorry capedcrusader but that comment was not directed to you personally.

I haven't got a sensitive bone in my body and I am no longer a Lysaght® Rep.and after 11 years I decided it was time to retire but I do appreciate your point of view and I understand that every one has preferences in life. The problem with a lot of heritage people is that they are fanatical and have cost a lot of people a lot of money because they slap heritage orders on propertys without the thoughts of some of the people that own them and want to modernise their property's.

What you have to remember is that what some of these heritage wankers do is have heritage orders placed on property's that they don't have a financial interest in.

What this does sometimes it devalues the property and stops people from having their choices in life and the only way around it for them is to sell at a loss.

It would be a very dull world if every one wanted the exact same thing. Me personally I like all new things and love new technology. I know this is not for everyone but I don't believe that what I like or dislike should cost any one else for what they like or dislike.

The laying of tiled pattern of roof sheets went out when they began to rollform roofing material. Sheets were only laid in that manner because of the way roofing was made which was very old technology. By rollforming you are only limited in length by the limitations of transport which is about 21 metres, although on some commercial jobs if they are large enough they will set up the rollformer on site.

The tiled pattern would probably not be obvious when it is laid in new iron and would probably take 100 years or more to appear when the sheeting begins to go rusty.

The reason I dare say that they dont roll Z800 would be economic. The process of manufacture at BlueScope Steel would require probably in the order of 150 to 200 tonnes of product to warrant producing it. To sell that amount of steel in Z800 would not be sold in 50 years and to hold that amount of stock is not in the realms of possibility in a profit driven company like BlueScope®.

They do manufacture up to Z450 in Custom Blue Orb which is mainly used for curving. See the quote from their website.

Thanks for putting up with an "OLD PHART" that thinks he knows a lot about nothing.
