LiamJones Posted July 16 Share Posted July 16 Hi, first time doing a roof and lead work. I’ve got a valley to work out, from where the hip meets a dormer. I’ve struggled to find any details online so have opted just to get a bit of lead up here and have a play. Am I on the right tracks here, before I bash it about anymore? Im considering cutting the fascia on the pencil mark, such that I can run that row of tiles under the fascia/soffit Link to comment Share on other sites More sharing options...

Dave Jones Posted July 17 Share Posted July 17 (edited) your on the right track, your dry valley is not in the right placer though. You need to centre it (its too far left) and also extend it down as far as you can then cut it to match the profile. Also its the wrong type of dry valley , you want the one with a 60mm upstand in the middle so when you cut the pantiles they sit tight against it, the one you have gives them no support so they will just drop. its actually for hidden gutter where 2 flat roofs meet and the tile type changes from clay to pan etc. https://www.dryvergeandrooflinedirect.co.uk/products/3-meter-grp-dry-valley-over-batten Edited July 17 by Dave Jones Link to comment Share on other sites More sharing options...
Mike Posted July 17 Share Posted July 17 (edited) You also need a bigger piece of lead, so that the fascia board is protected where it meets the tiles. You may be able to place the lead under the tile as a soaker, if the pre-formed valley projects further. Edited July 17 by Mike 1 Link to comment Share on other sites More sharing options...
LiamJones Posted July 18 Author Share Posted July 18 Thanks so much @Dave Jones @Mike. Thoughts on the dry valley closures top and bottom? presumably with counter batten, the valley would sit ontop 2 battens? As opposed to sitting on 1 batten for a normally battened roof. the valley is centered to the valley, I think the lead work in the photo is making it look like the center is off to the right, due to how the lead is formed over the tile Link to comment Share on other sites More sharing options...
Dave Jones Posted July 18 Share Posted July 18 the proper valley has a groove either side where the vertical battens go to hold it into place. Here is an example of a flashed dormer up the road which is similar, the lead at bottom could be dressed a little tighter depending on personal preference but you get the idea.

LiamJones Posted July 27 Author Share Posted July 27 Replaced the valleys with the ones you suggested @Dave Jones. Just waiting for the bottom closures to arrive and will have a play flashing the bottom of the valley. Probably with some lead too. just had another look at the photo above. I was going to install a gutter to the dormer, but I’m tempted not to bother now! Link to comment Share on other sites More sharing options...
Dave Jones Posted July 28 Share Posted July 28 looking good, klober do a nice rubber valley closer you can cut to suit. https://klober.co.uk/dry-verge-and-valleys/roof-valleys/grp-dry-valleys/a/dry-valley-closure +1 for no gutter Link to comment Share on other sites More sharing options...
LiamJones Posted July 31 Author Share Posted July 31 Thoughts on how to finish this? Cut the rubber closure level, then underlay lead that laps the fascia? id like to have gotten the closure tight to the fascia, but there’s not enough material or flex.

Dave Jones Posted August 1 Share Posted August 1 try and glue the rubber to the fasica so its flat. dress/cut the bottom of it so its parallel to the fascia. Also may be worth putting another 1 or even 2 battens on the hip, the hips stand very high on the pantiles. lookiing good. Link to comment Share on other sites More sharing options...

Dave Jones Posted August 5 Share Posted August 5 looks good. may be optical illusion but looks like the ridge row of tiles is slightly different gauge to the rest ? Link to comment Share on other sites More sharing options...
