About 15 years ago I repaired several areas of rust perforation on my now 50 year old corrugated iron roof using adhesive-backed heavy aluminium tape. I rust killed first then put on the tape and painted over. I've checked at regular intervals ever since and there has been no deterioration. Quotes to replace the roof were not affordable at the time and I'm glad I didn't accept them. Cheers Billy 8-{)	Billy T (70)

Plus buy a new tile... one! lol Joe... under the tiles is nothing - just the ceiling. Apparently it's supposed be like that to allow proper airflow. The house is only three years old, and is watertight, apart from this damn cracked tile. Image here (www.imagef1.net.nz). [edit] And here (www.imagef1.net.nz). Well who ever installed the tiles proabably breached the building code if they were installed recently, as it has to have building paper underneath the tiles. This prevents water getting inside (at least for a short period of time) if the tiles fail. Building paper is vapour permuable so will allow ait flow.	robbyp (2751)

Just had a look at your photo, and it clearly shows that the tile has cracked from the bolt used to attach the dish. Concrete tiles are very weak in tension, and they shouldn't be attached that way. I would get onto the person who installed it to fix the problem.	robbyp (2751)

We paid to have a professional inspection prior to purchasing the place.	Greg (193)

The tile would be in compression between the bracket and the batten (still bad). The Building Code as at Nov 2006 doesn't require an underlay in all cases. Without access to the Standards mentioned it seems determined by roof pitch.	PaulD (232)

Without access to the Standards mentioned it seems determined by roof pitch . I was talking about the atual bolt hole, where if the person who installed the screw drilled a hole too small for the grub bold, when the grub bolt is screwed in it will crack the tile . Who knows if ti was actaully drilled all the way into the batten . This crack may not have been noticable until someone else went onto the roof and caused movement of the tile when they moved the dish I would still want building paper underneath my tile, even if it wasn't required . Tiles have lots of gaps between the laps, so there is lots of potential for water entery if you get wind blowing the water in from a particular direction . I don't think you need building paper for low pitched membrane roofing, but I always specify building paper under roofing materials . I think it can also depend on councils, as some councils won't approve plans without building paper under the roof cladding .	robbyp (2751)
575323	2007-08-02 11:43:00	This prevents water getting inside (at least for a short period of time) if the tiles fail . Building paper is vapour permuable so will allow ait flow . Is this for real? If it is vapour permeable then surely it will be moisture permeable as well, and vice-versa? I thought building paper was intended to act as a moisture barrier and being impervious to water, that would also include water vapour . What do they make it out of these days? It used to be "tar paper" which was thick paper impregnated with a hydrocarbon based pitch but have they now gone hi-tech? Cheers Billy 8-{) :confused:	Billy T (70)

Cheers Billy 8-{) :confused: No building paper has always allowed moisture to exit the building . Building paper is to stop drafts and water in liquid form, such as water dripping, from entering the building . Otherwise you may as well use polythene as the barrier, but then you will get the building rotting from within, if moisture can't escape, which is why it isn't permitted .	robbyp (2751)

575326	2007-08-02 12:21:00	Tell your insurance company that it was Sky's fault, and make sure they know this beyond any reasonable doubt. You should be able to convince them to cover it, and they will go after Sky for the money. With any luck you won't lose your no claims bonus as they have someone to get the money off.	george12 (7)
