We’ve developed an alternative solution for roofing tiles that effectively replaces the tile with a flashing that sits over the fixing point.
Since slate is, by nature, a fragile material, this system avoids the dangerous and prohibited method of drilling through it, which is where the system got its name, but it can easily be used with any other roofing tile.
A metal plate sits so that its longer edge runs in the same line as the rafter and fixes into it using 2 screws. There is a threaded rod already attached to the plate that allows the aluminium flashing to slot over. We can then connect any of our mounting rail profiles to the threaded rod.
The flashing is made from aluminium with a specially bonded EPDM cone integrated into it. During installation a hole is made in the top of the EPDM cone to make room for the threaded rod of the metal plate and once this is pushed down and positioned, it provides a weatherproof seal.
As with all our EPDM products, it has a high performance in resisting UV, so it doesn’t crumble with exposure to sunlight.
