JimmyR Posted May 16 Share Posted May 16 Can anyone confirm if a traditional slate roof repair can have dry hips and ridges? I have photo examples of a finished job but don't know if it looks right or not. It just doesn't look right to me as the hips/ridges don't look properly connected. Can anybody advise please? Thanks!

JimmyR Posted May 17 Author Share Posted May 17 Thanks. Does the repair job in the photos look professional? Link to comment Share on other sites More sharing options...
Redbeard Posted May 19 Share Posted May 19 I know we know this, but Roofing Superstore says: "A dry ridge system simply involves fixing ridge and hip tiles to a roof without sand or cement mortar, but instead with screws and clamps, which fix each ridge tile to the roof, with waterproof unions beneath the screws to divert water away from the join." I could be wrong but the ridge and hip tiles in your pics *seem* to show 'bog-standard' tiles (which would, 'in the old days', have been bedded in, and pointed with, mortar) fixed 'dry'. Therefore (a) it looks odd (to me) and (b) it makes me question what is holding them on. It may be that there is some clever bracketry underneath, in which case fine (-ish), but personally I feel those tiles do not look right without pointing. (I do appreciate, BTW, that the 'adhesive qualities' of mortar mean that an awful lot of 'wet fixed' ridge and hip tiles are actually just 'sat on top' a relatively short while after installation.

It is not in line with my aesthetic leanings, but then I love MZs! Happy to be disagreed with! Link to comment Share on other sites More sharing options...

Nick Laslett Posted May 19 Share Posted May 19 The perfect thread to use the random photo I took of my ridge tile showing the fixing method. I still marvel that one screw and some plastic tabs are all that holds the ridge together. I look at the giant steel beams they made me install for the roof and wonder at the dissonance of modern buildings regs. Link to comment Share on other sites More sharing options...

Yes, I get that with those special (?) tiles, but those the OP shows look like bog-standard overlapping 'Victorian' (well, mine are) tiles. Not sure how you could 'secret fix' them? But in answer to the OP's original Q, " Can anyone confirm if a traditional slate roof repair can have dry hips and ridges?" I am pretty sure I have seen older roofs 're-ridged' with those such as @Nick Laslett shows. @Nick Laslett, I take it there is a 'placcy cap' goes over the joint...??

The picture is how the roofer left it. A cap might finish it off a bit neater. It doesn’t even look very rain proof to me. I wonder if there should be a cap.

IIRC the rain proof layer was under the ridge tile with the ventilation at the edge by the roof tile. 1 Link to comment Share on other sites More sharing options...

The rest look to be held in place by virtue of gravity? Were they bedded in mortar or any other adhesive? Link to comment Share on other sites More sharing options...

Isn't that just another building, so you see a roof of one building and wall from another? Link to comment Share on other sites More sharing options...
