Advice about roof

Sharra

If anyone can give me some advice about this I would be most appreciative.
Although our roof tiles are fine, the kind of lining that lies underneath them is ripped and has holes in it. I'm guessing this is why our loft seems slightly damp.
Is there a way to patch this up or do we need to get some roofing people in to sort it out? Does anyone have any idea of a cost for this? We are in a pretty bog standard end of terrace 3 bed house.
Many thanks

for a temp repairs you can apply mastic and some roofing felt (cut to shape) on the holes etc..
but the proper long term answer im afraid, is to remove the tiles and replace the roofing felt complete. expensive.

for the temp repairs its either diy or get a man in for a days labour. materials would be cheap.
for the whole roof? how long is a piece of string? a few thousand quid minimum, plus say 500 for the scaffolding costs.

Unlikely. If rain is getting under the tiles (not unusual) and then running down the felt and hitting the ripped areas ... there will be wet patches on the loft floor / insulation .. and also on your ceilings. If there aren't any wet patches - any rain getting to the felt is avoiding the ripped areas. The damp is more likely down to inadequate ventilation in the roof space.

If there's a few rips - rather than a colander effect? You can patch by cutting a piece of felt to the width of the rip. Then easing it up into the rip so the new felt is (50%) inside the old felt on the down side of the slope. But (50%) of the new felt .... is inside the old felt on the up side. Got that . Years ago - they simply left it like that. But it makes sense to use a black mastic on the 50% of the new felt you can now access and stick it to the old felt it is overlapping.

That encourages the 50% that's inside - to lie flat with the old felt in order any water continues to run down the slope and doesn't backfeed towards the rip. Very old fashioned solution - but works OK if you're careful. But do ensure the black mastic will stick felt to felt - and not dissolve it ... before you start.
