Roof Tile Misalignment - Please help

blackmax · Feb 12, 2008 3:02 pm

Hi folks,

Currently having a single storey house being built in Brissy (single storey, tile roof). I've recently noticed something that's causing me to lose sleep over.

House is nearing fixing stage, all the framing is complete, roof on, plaster complete, etc. I have concerns over a section of the roof where the tiles are misaligned and there appears to be a 'wave / sag' appearance.

When looking along one side of the house, I've noticed a considerable series of sags / waves on a section of the roof tiles. The wave extends for about 5 or 6m, It appears that the tiles are 'sagging' in one section of the roof - and when you look along the length of the building it's quite noticable and disturbing.

My question is for those who have a tiled roof, has anyone had any troubles with their roof's sagging / bowing at any spots? Is this commonplace? Is it acceptable? My main concern is when it comes to selling, as from the front entrance it's really obvious and offputting.

Also, does anyone know how this would be rectified? Is it a major problem to fix? My guess is that the tiles would need to be removed, and battens fixed and the roof brought back to level. Is this what happens?

Any advise would be greatly appreciated, as it's the main thing that's worrying me at the moment.

Hi, I'm not really sure but you could get an independant building inspecter to check it out for you.

Hi aussiebell,

I'm just waiting for a reply from the builder before I do anything else. If they play hardball & they don't think there's a problem then yes, I'll get a third party in to inspect.

I think they'll fix it if it's considered a problem. At the very least it's an asthetic problem.

I was hoping someone here who has built a tile roof has had to deal with a similiar problem & what was the outcome for them. My main concern is that it might add to the completion date.

What's your spacing between trusses (those triangular bits)?

600 mm is a common spacing. Anything much bigger than this and things start to bend, but then it depends on the thickness of the tile battons (the timber that spans across the trusses).

can you post a few photos??

For the time being I'm not going to post any photos, because I don't want to make a big deal of it if the builders are going to fix it. I don't want to make a mountain out of a molehill.

I know what the cause of the problem is, I just want to know if anyone has had a similar experience and how was it fixed - I can think of a few ways of repairing it, but I want to know what the common industry practice is.

The builders have agreed to look at it, which is all that I've asked them to do so far. The only reason I posted this thread was to give me some piece of mind whilst I wait for their reply.

I wonder if I'm the only one who's had the problem....
