Has anyone every used the TopSlate product?
Apparently, CMP makes two versions:
1) Larger version allows 12" slates to be clamped into position, hiding a majority of the ridge metal.
2) Smaller version does not use slates, looks more like a typical metal ridge roll, but larger in profile.
I'm thinking about using the smaller version, to ventilate a "cold roof." The unit appears to be well designed and is available in various metals (Al, Cu, 304SS). They avoid nailing the flange by using a top clamp system.
I'm concerned that the higher profile will prevent maintenance of the roof (i.e. securing a ladder hook over the ridge).
In a similar vein, if the clay ridge tiles are popular in Europe - and they are used on most tile roofs - then how do they accomplish routine repair / service? Are there other techniques, or is it simply more difficult?
Any comments would be greatly appreciated!

I am familiar with the systems used in Ireland and the UK.
The majority of ridge finishes are ridge tiles bedded in mortar or sand / cement mix, the same detail applies for slate and tile (concrete or clay) roofs.
The ridge tiles can be fired clay or concrete, some use a fibre cement ridge nailed on fibre cement slates (asbestos cement).
Servicing the roofs are no more difficult than most US systems I have seen, in fact easier than setting a roof ladder against a nailed on slate acting as a ridge.
I would have to see more than the CMP web site before I could offer a reliable opinion, perhaps my conservative ways of working would say no to a system that looks like an extended roof.
When we fit a ridge tile it is designed to overlap the top slates by four inches, sitting snug to the roof as opposed to sitting "off the roof".
I think the major difference to the way we service a roof is we use a bigger hook on our roof ladders.
The larger hook allows the ladder to sit over the ridge tile while the front is longer and extends below the ridge tile.
