Just did one of these wasn't as free flowing as your video , found the cut undersarking and roof felt couldn't be nailed back onto the batten, it were to low, so I had to do an immense amount bodgery to get around the problem?. Hope it stands the test of time.
Most helpful indeed, as I had little idea regarding the procedure, or how to go about such a task for installing a slate vent. Thank you so much for posting this clear & concise gem of a video in this regard. It's a marvelous illustration, cheers! :-) .
Clear and helpful video. I have to fit a vent on a low pitched roof over my kitchen extension Subscribed , but at 71 years old I'm not going up on any more roofs after this one ! 😖😊
One of the big issues is actually when you go to install, and there's a rafter in the way. That's when the jiggery-pokery begins. In older places like mine the rafters are only about 12 inch apart (Designed for the old heavy slates). Because my requirement was near a hip, I could fudge the offset required with a double width fibre cement tile (Looks wise).
@@davesalter Mainly for the benefit of anyone reading this thread, is that the vent system shown is designed for an additional coupling that allows an extraction pipe to be connected and thus to an extractor. If someone is simply manually ventilating a loft space then really you could cut that back flange down to the width of a roofing batten (18mm or 25mm depending) and you wouldn't have any issue with the rafters being in the way (or cut the back flange in a way to not hit the rafter but still partially project past insulation if you have that directly below the battens/roofing paper).
@@cowboybuilder Yeah fair points. Or you can actually get a vent with no protrusion for venting only, the vent in this video can be used for venting of loft as I've shown or as you say it can have a pipe added for bathroom/kitchen extraction.
Hi Dave ..really helpful thanks. I have 4 installed already from my previous loft conversion but a couple have slipped about 5 cm down , so the rivet/ nails can’t be holding them in place? Is there a way I can secure the vents without taking tiles back off? A roofer looked at it and said they are secure, and won’t drop any further but they shouldn’t slip ? Thanks for your advice
I would imagine whoever fitted them did not remove the top 2 slates so they could be nailed in place, so they wont have nails if they have slipped. Its possible the protrusion on the back of the vent is stopping it from slipping out completely. If you dont want to remove the slates you could try putting some silicone adhesive underneath as i show at the end of this video, then pushing it back into place and fitted a rivet to hold it down. That's about the best you can do without removing them. Thanks for watching, and sub for more! 😀
@@davesalter Thankyou , I investigated further as I have a scaffold up ..they are flat profile vent with no protrusion on the back and the tiles underneath haven’t been cut and yes , not nailed in place - so that’s not going to give much ventilation..hence my condensation problem.! Really appreciate your video and reply.,you aren’t based near brighton are you? 🙂
@@t.m.p8187 Wow, yeah thats shocking, well good you've seen it so it can be sorted correctly! Based in Halesowen, West of Birmingham I'm afraid. Good luck!
I would consider that a short cut not worth taking, you wouldn't be able to nail the vent in place which I would much rather do, it would be difficult/impossible to get the vent under the top two slates and get the vent section in the hole with a slate vent like in the video i would think, without breaking slates in the process. Also the H&S aspects of the potential silica/aesbestos dust I'd rather take them out. So in answer to your question I'd say no, but i am sure people have tried it that way, lol. Thanks for the question!
