Roof lining

frugglewump

Having just got access into our loft I can see that there is no insulation at all between the joists and no lining between the loft & the slates. Insulation & boarding the loft I can cope with. Could someone recommend the best thing to do about the lining?

I was under the impression that felt had to go over the rafters before the slates and I don't want to have to pay someone to re-do the whole roof.

Also, at the moment I can see by the daylight where all the slipped slates are - can they be fixed from the inside?

My house is 1930 with slades and i haven't got any felt between the raffters and slades.

I think it's an age thing too. Our house is circa 1930 and doesn't have underfelt beneath the tiles. I think there is a company who can sray a lining on, but I think they are expensive.

I'm in the same boat. 30's house, no felt, and some slipped slates. There are only one or two tiny gaps, but as I want to reinsulate the loft and board the floor, I'll need to ensure there are no leaks.
I've heard about the spray solution, but I've been warned off it, as it's only really a temporary repair.

As for fixing the slipped slates, you might get lucky and be able to move them from the inside. There's no real weight on them, so they should move quite easily, but just be sure you don't move them too much, or you'll have a hell of a job trying to fix a 6 inch hole from the inside :eek:

If you do try this, let us know how you get on.

Well this is an 1890s house.

I definately won't be using the spray stuff. OH seems to think we can get strips of felt and stretch them between the rafters from the inside.

That won't stop any leaks though. You need to have the felt overlapping, and with the battens attached to the rafters, that'll be impossible.
IMHO, it seems that the only way to solve this problem is stripping the roof and starting from scratch. Not cheap or moneysaving, but at least it'll be permanent.

There is only one solution to all of your problems...and that is to remove the tiles and battons and lay down new felt. It can't be done any other way.
There is a new felt/fabric on the market these days that alows air to penetrate it for circulation, but not water.

I would stay clear of the spray stuff it makes the wood rotton underneath after a while as there is no circulation. Plus, if a tile breaks, it cant be replaced because it's glued in with the spray.

If it's been like that since 1890, I wouldn't bother doing anything with it apart from replacing any slipped/broken tiles. As others have said, once you start interfering with the circulation, you end up with all sorts of condensation problems.
