June 20, 20224 yr Hi @Onoff I ground the underside of the tiles and sealed the gaps with lead sealant

June 21, 20224 yr Author Picked up the 14 stainless brackets earlier. At a fiver each, new old stock, I had to. I'll need to cut and shut to get them to sit down on the bottom tile: 18mm at the top, 16mm at the bottom: Rough plan is something like this and lop off the top L bit:

June 22, 20224 yr 7 hours ago, Onoff said: To show how far off the tile the bracket is. Is it sitting on a rafter? Can you move the bracket to the left to get it between rafters? Then fit a noggin internally at a lower level to get rid of the packers and have the metal on the tile.

Then fit a noggin internally at a lower level to get rid of the packers and have the metal on the tile. It's sitting on a rafter. Can't see the point of the noggin idea. It's not done like that.

June 22, 20224 yr When you chop the roof hook dont have it resting on the tile but a few mm clear of the tile. The hook transfers the weight of the array plus wind/snow load through to the rafters. If the hook rests on the tile or can flex onto it, all the load goes through the tile with a fair chance the tile will break.

I don't think it's feasible to re-drill. There's not the meat plus when I trim to lower it, I'll end up with the slot open at the bottom. More likely a cut and shut job something like this: Edited June 22, 20224 yr by Onoff
June 22, 20224 yr I would think it's worth customising as much as possible, so the welded solution is good. Bearing in mind what @Dillsue mentioned you could also redo the bend to bring the cranked end closer to the tile above the bracket so reducing the leverage that will tend to push it down onto the face of the tile below (it looks to be around 40mm too long).
June 22, 20224 yr In the sketch you show the vertical adjustment slot for the rail being cut off. If you loose that adjustment your rail has to follow the contour of the roof which could be all over the place. Might be worth running a string line across the roof in a few places to check its flat otherwise you might want to keep the adjustment?? Recently fitted an array to my daughters house and with the outer hooks set lowest and those on the middle of the roof set highest, there was still a sag in the rail. Fortunately it wasnt obvious from the ground but you could still see the sag. Not sure who built the roof but they should have gone to Specsavers!

July 7, 20224 yr Author I just can't catch a break! I got a good deal on an expansion tank, pump and solar thermal controls on Gumtree. Chap collected for me and was holding onto it until a mate down here visits rellies near Edinburgh. He's just messaged to say given the cost of fuel he's now going to bus/ train it up rather than drive.
