Browse Forums DIY, Home Maintenance & Repair 1 Jun 07, 2009 12:39 pm We live on the top floor of a 1930s block of units in Potts Point, Sydney with a pitched tiled roof above. The roof has previously been "sarked" using a blue plastic lining which has "blown out" in numerous places where the wind has got underneath the tiles. Water penetration resulting from the above has previously damaged the ceilings and, as we're about to embark on a major renovation project to our unit, we want to avoid this happening again. The Body Corporate for the building plans to repair/replace the sarking but the old tiles used are the original type that were tied to the roof batons with wire, rather than the modern ones which are nailed to the batons. This meant that once the sarking layer was in place the tiles could not be tied to the batons - this allowed them to lift in the wind which exposed the sarking and eventually it blew out causing the damage. I know there are heavy-duty fibreglass reinforced sarking materials available (e.g. Bradford, Fletcher)- would these allow for penetration of ties through the sarking which would enable to tiles to be tied down? Re: Sarking for old roof tiles in high wind area 2Jun 07, 2009 12:55 pm I'd assume you are using a professional builder, so ask them - but in answer to your question, the fibre reinforced products will hold with holes in it - but i suspect they are not going to want to do that - very time consuming. Staple it underneath afterwards is one option. Re: Sarking for old roof tiles in high wind area 3Jun 07, 2009 6:05 pm The holes would be to tie the tiles to the batons through the sarking to prevent the tiles from lifting in the wind. Would the sarking work if the tiles were tied to the top of the batons (as they would have been originally) and the sarking was attached (stapled?) to the underside of the batons? We want to be able to specify the solution to the builder rather than have another quick-fix solution which doesn't resolve the issue. Re: Sarking for old roof tiles in high wind area 4Jun 07, 2009 6:47 pm The sarking stapled underneath is actually a better solution heat wise as it reflect more heat when there is an air gap. I understand that the holes would be to hold the tiles down Building Standards; Getting It Right! Hi all Iām in VIC and had some storm damage in my garage a month ago.
