  QUESTION: Heritage project with Lead washers 18 Jan 2007 NSW, Australia


Vostek Industries is a Sydney based roofing company. We perform projects ranging from domestic to industrial, heritage to modern. We are presently involved in a heritage project that calls for old style roofing screws with lead washer. Washers may not sound like much, but there will be 10's of thousands of them in this project. I would like to know if this would be considered to be OK, or if under some type of legislation, we should be looking at another type of roof screw?

Subject: RE: Does the building code stop people using lead washers?

Hi Huma

Unfortunately the Building Code of Australia only restricts the use of lead flashing and does not mention the use of lead washers.  The reason for this is that they are not generally used in today construction techniques.

Sorry that I could not help further.
