Bad Roof Repair?

othafa

OK thanks for everyones help. Still seems to be no way of telling if theyve hit enough trusses to hold the roof on. Don't suppose for a minute they're going to take the tiles off to prove it.

As for corks? I'd need at least 50!

I'll see what he says on Monday.

There are some contributors to this thread who clearly have no idea as to roof construction. Don't believe all you read.
It is plausible that the exposed nails are those from the counter battening and the OSB is indeed fixed properly. You may be able to work it out, the nails are paslode and can't be longer than 90mm. What thickness of OSB did they use?

othafa

The OSB looks about 1cm thick. Not sure what you mean by counter battening.

The nails are alongside almost all of the trusses in a straight line, anywhere between 1 cm to 10 cm away from the truss. There are no nails protruding anywhere else through the OSB.

The nails protrude 2 to 3 inches into the attic space, even if it's "normal" I'd argue it's dangerous.

Counter battens are usually something like 2x2 which are fixed through the OSB( or insulation when over the top of the rafters), to the rafters, so the tile battens can be fixed to them.
It does not matter if there are misses as long as they got enough through the OSB into the rafters.

This is an example of 2x2 counter battens on top of 120mm insulation boards.

Ok so if they've used counter battens and the counter battens are nailed through the OSB into the rafters then I'm good.
Still think it's pretty shoddy work to have missed the rafters so often and if its nailing the counter battons just onto the OSB then theyve used the wrong size of nails.

If they have used counter battens and are fixed to the rafters you are good.

Hi, me again. Now the scaffolding is down it looks like the first layer of tiles has not been laid correctly.

The right hand side at the back looks like this and both sides at the front. Can even see what looks like roofing felt blowing in the wind. Is this some fancy new way of laying tiles?

could someone kindly edit the link above to work, thanks

This should work now.

Ok so the nails are from the counter battens, they are not going to come and cut the ends off.
Unfortunately the tiling is rubbish, they have screwed something up, the dry verge running up the edge of the tiles looks to be too far away from the wall on that picture, there also seems to be a lump under the end of the roof (possibly the wall) look at the way the line curves from a reasonable position on the left, a strong wind will have those tiles off unless they have nailed all of them down (although im not sure that will be enough).
