Roofing felt after chimney rebuild
I had a tradesman rebuild my chimney up from under the roof.He had to cut the roof felt to do this.Should he have attached the felt to the chimney so if the rain ever gets through the roof tiles in the future it won’t rain in around the chimney?
Advice from 13 local tradespeople
The felt is not normally attached to the chimney. felt is an under layer with batten and tiles on top of this, then a flashing(usually lead) is then dressed onto the tiles and cut into the mortar on the chimney to provide a water tight joint.
Yes he should be doing all at once
No the lead work on the outside of the chimney will prevent any rain leaking through
The trades man should have installed a led flashing around the chimney then when roof tiles go back on it will fold down on top stopping any water from getting in.
If he done the lead outside properly then you don't need to bother about the felt as water cannot go through the lead.
Should be lead around the bottom of the chimney if that helps
Putting felt on the chimney wouldn't really do much to be honest. We use lead around the chimney, chiselling into the mortar slightly to be able to get lead inside and then over the roof tiles/slates that was there is no chance of rain getting in via the chimney. I hope this has helped.
Crafted Woodwork.
No the roofer should of fitted soakers and also a lead flashing on the chimney but should get the new felt as close as possible to the chimney stack
Cut a slot in the chimney all around and use lead to cover all around200x200mm
Hi there around the stack there should be battens the felt should be tacked too but also enough overlap to be folded under the flashings around the stack
No the lead around the chimney and on tip of the tiles around the chimney will stop water coming in.
It is advised that the felt does turn up the side of the chimney just incase any off the lead flashing or tiles fail as a second barrier
But on the other hand years ago there wasn't any felt there was only bodging trouled on to the back of the tiles or slates to prevent drafts this was a mixture of hourse hair and lime mortar mix
Providing the lead work has been done properly from the chimney above tiles then it shouldn’t leak, but I normally flab the felt up against the chimney then tack it with some Battern then lay your tile on top then fit your lead work
