Cement tiles moving in stong wind

[verawood]

Hi All

After some help with what to do about my cement roof tiles moving in strong wind and letting rain in.
The roof was repointed not so long ago and still looks ok from what I can see.

So I am thinking about having generous amounts of silicone (or something) injected in between a majority of the tiles that can be prised up enough.
On others near the capping, silicone forced in to any gaps between the tiles that look like they need it.
It seems to be the rear of the house so just a triangle of tiles.

Attacking it from the inside would be much more difficult with heater and a/c ducting in the way.

To the point; does any one have any suggestions re the best product to use, please.
Bunnings rep recommended Selleys Roof and Gutter silicone.

cheers

Get someone in the roofing industry to have a look and not the ones who did the re-pointing. Perhaps Matt (Simplicity) might be able to advise on someone.

If it wasn't a problem before repointing but is after then the contractor has done something wrong. Get a tile rep to inspect, they will now what to look for.

Failing that, then the following:

Forget the silicon, only good for metal roofs, on cement tiles it will simply fail.
What concerns me is you said they lift in strong wind, has this always happened or only after having the roof repointed?
Is it just a case of the wind simply forcing the rain under the tiles.
If in fact the tiles are actually lifting, you need to get the wind clips from a tile company and fit them.

Like others have said, I think you need someone to go over the roof, an have another good look.
Unfortunately these days not all experts come from the same mould.

Cheers Matt.

It also sounds like one of those gypsy type travelling roof restorers

You can get storm clips for roof tiles in high wind areas but it f you didn’t have an issue before and now you do it is likely something the last contractor did causing the issue

Hi All

Thanks for your posts, the roof was repointed in an effort to stop the rain coming in, but only fixed it for "normal" rain and wind, not the full on stuff.
The roofer was recommended by my BIL who had used them 3 times with no probs.
The builder has gone out of business, and didn't leave any spare tiles.
That's why I have to find a solution.
I will have to search for storm clips; not familiar with them.

Are you sure it is getting under the tiles? It is often the gully (if you roof has any) that is the problem according to my father who was a builder. He said often the metal they put under the gully (not sure what it is called) is not wide enough in heavy rain. Worth a look.

Its called a valley and the tray is the valley iron.
If it is the valley that is leaking then its more likely that excessive traffic on the tiles at the valley edge has crushed the small gutter on the edge of the valley.
Don't try to double guess what the problem is, get a tile rep/supervisor to check it out. You doing the work will void your insurance if ever you need to make a claim resulting from a problem with the tiles, I used to do insurance work and I know how they think and access each claim.

What's the pitch?
Is there a valley?

Hi All

Thanks very much for all your replies, very much appreciated.

The area is a triangle of tiles at the rear of the house with capping tiles and pointing grout down each side.
The original pointing just fell out at the top of the triangle, most likely poor workmanship and not up to standard.
The rain still comes in at the same point inside as before. I have heard the tiles move in very strong wind.
Don't know the pitch, but looks the same as other houses around; is there a "normal" pitch.
I searched storm clips and fitting would be a BIG job.

I tried an insurance claim for the original leak. HUH - VBA ins put more hurdles than the Grand National. EG: MUST sue builder first even though no longer in biz.
House ins mob said yes, I gave the go ahead, then they said that they would only repaint the affected room; I had to get the roof fixed first.

At my age and being a pensioner sometimes the best solution is out of reach, physically and financially. So still looking for a solution.

Thanks again

Article in todays paper seems to suggest my experience with VBA all too common.
