Advice for rosemary roof

[Easters]

I also flash under the bracket and cut the tile so no lead can be seen and 100% water tight. So any pressure from the installer for the fatter sort of roofer/sparky can not break them.
But also even after the job is finish I have know ppl to go back from high winds putting to much pressure onto the tile.

Hi guys, just done a rosemary roof and we went through the tiles with hanger bolts, protecting the entry with mastic and grommitt 12mm hole for 12mm bolt. The key was to replace the old rosemary tiles with softer tiles which are under the panels. you can also use these tiles to replace the ones you will inevitably break! Hope this helps

Well that isn't what MCS teaches- no mastic..
K2 do the P1000074 Roof Hooks krannich p/n is KD12758 works great

From MCS 3002:
"All roof penetrations (e.g. for PV modules, cables or bracketry) must be durably
sealed using purpose-made products capable of accommodating the movement
and temperatures to which they may be subjected.
Note: In all circumstances the building's weather tightness must be maintained. Holes drilled
through roofing felt and/or roof tiles/slates sealed with mastic or silicone sealant are not
considered durable.

Thanks Guys, you are right in part, but the K2 system uses hanger bolts and brackets to fit as we have, mastic is a secondary sealant. Like the look of the K2 system and we will take that on board!
