The felt is only a secondary protection, there are thousands on thousands of water tight roofs without any felt, so no need to repair if no leak. Could keep birds out by any method that blocks the hole, but doesn't interfer with roofing.

Using a felting torch isn't really for Diyers. They can be dangerous, heating the bitumen on the felt needs to be just enough to get the felt to stick to the roof, too much heat and you burn a hole in the felt. You could try cold fix bitumen, prime the substrate, and then stick the felt to the...

We have a problem with the hole where our central heating flue exits the roof. I'm unsure if the problem lies with the hole in roof, or the kit used to 'seal' the hole around the CH flue or the hole in the felt from what I can see. Its particularly noticeable today as its windy and raining...

Felt was originally designed as a wind and crud barrier that also happened to be waterproof. It is by no means meant as the main protection from the weather as this is the job of the roof tiles. Felt, after all, is full of holes once the lathes are fixed. :roll: 8)

then proceed to put lots of holes through the mineral felt when nailing the lathes. :roll: 8)

Hello Forum Members, I need suggestions on the best way to temporarily fix a hole in the slate roof of my house from the inside (i.e. from the loft area) till I can get the roof retiled properly. Objective is to prevent or minimise the ingress of water into the loft area. Due to the...

You should have originally used some kind of "stuck-down" felt such as "peel and stick". You now have the nail hole issue and rippling and bubbling can be seen, which means moisture has penetrated below the surface felt layer. In the long run, whatever that is, your felt roof is shot. Maybe the...

A tile vent terminal has a 110mm spigot which needs to be connected directly to the extractor fan via flexi hose. This spigot passes through the felt. A hole is cut into the felt or membrane, the flap of felt is pinned back to the nearest roofing lathe (batten) and is weathered by a manufactured...

If you go for the Velux's make sure they are fitted as per the instructions. You have to cut a hole in the felt to fit them, and then should fit a 'nappy' between the window and the felt. This maintains the secondary protection of the felt, so wind driven rain under the flashings will be...

25mm holes drilled in the centre of the joist would be pragmatic: JG (or Cu with many st. conns and few wisps of felt).

There isn't any. But if you seal any gaps and holes at the eaves and verge, then the birds can't roost, and wont peck at the felt

We had a flat roof installed as part of a loft extension and it is covered in felt. The builders then cut a hole in the felt to put a flat window in. This is now leaking and they are claimed to have fixed this with a sealant. Will this work or will they need to refelt the roof to ensure it is...

I have noticed a piece of roof tile was broken of a tile very small piece but was big enough for a bird to get in. On the inside however there is a big whole in the felt. The best was not in use and I have removed it and was wondering if just filling the hole with I bit of expanding foam would...

Hi, Was doing a few bits in the loft last weekend and noticed the felt has perished in a few places (house built in 1977), with a few holes/rips in the felt. There are also a couple of vent holes that someone has previously cut in the felt. Yesterday, it rained hard all day, with a strong wind...

I had the same problem I took the filters out and felt the exit hole where the water goes I cut a bit of hose and put it in the drainage hole and blew down it.....it stunk! Problem solved

could you not put a "spare" bit of roofing felt over the hole then "paint it", i was just thinking it will then give the "paint" support

So, schoolboy error- i know. We had a few to many beers and thought it would be good to have a disposable BBQ on our balcony, a few beers later when i picked up the bbq tray it had burnt through our balcony floor. I don't really know what the floor is made of but under our balcony is another...

Yes, putting holes in the felt should be avoided. You could remove them and seal the felt.

Acceptable, no - the felt is the rooves secondary seal, to ensure ant weather which makes it's past the tiles, or it case of tile loss. I cannot comment on methods of repair.. Seems they may have been careless about removing the old nails, managed to miss some, and they have holed the felt.

The three layer felt system is usually fully bonded to the substrate. What Kingspan are suggesting is that if you use their product AND decide to go with hot-pour-felt then you need to apply a partially bonded layer, i.e. a layer of felt full of holes. I would imagine you are free to use...
