Hi
Ridge and verge on our 75 year old need re-doing. Definitely decided against any dry verge many roofers seem to think is preferable.

However, not so sure for the ridge, the dry system would provide ventilation whereas the wet does not, however the current ridge tiles look good as new and plastic ones certainly won't last decades like these are.... can anyone advise on pros and cons of the wet or dry ridge? And what, if anything, can or should be done for ventilation at top of roof in the wet system?

Also, what is a good mix to use - esp for the verges. I've seen houses in locality that have been redone and its an awful grey mess that's often cracking. The current pointing in the verge of our house is more beige, and you can see sand (almost fine gravel) and what looks like bits of chalk?? It's lasted ages and looks so much better - any ideas on what this might be/best mix for longevity?

Thanks in advance.

Hi,

Unless I have misunderstood,
however the current ridge tiles look good as new and plastic ones certainly won't last decades like these are...

the dry ridge systems don't have to use plastic ridge tiles, if your existing tiles are fine (as long as they come up without damage), they can be reused (depending on the dry ridge kit chosen).

However, if you would like a specific mortar colour for the verge, then go for the standard wet ridge.
It may look a bit odd having the sandy coloured mortar on the verges and the black or red plastic brackets holding the ridge tiles in place!

For a wet ridge, there are ventilation tiles available, such as:

But, if you haven't had any issues with condensation up to this point, you probably dont need to worry!

Dry ridge has the benefit of being fast and needing slightly less skill to do properly, whereas a wet ridge will take time and skill to do a neat job.

Thanks for your response, that's helpful. Good to know that the same tiles could be used for a dry system at the ridge. I am more inclined towards same on both for reasons you've stated.

It's true we haven't had any apparent issues to date, but also looking at options to improve insulation/airtighness, and want to be sure the roof doesn't suffer.

Will discuss options with a couple roofers.

Thanks again.
