Kytun dry valleys with Sandtoft 20/20 tiles are they worth it and what to watch out for?

[boxrick]

I am in the process of rebuilding my roof and one of the roofers I had out is recommending Kytun dry valleys.

My current materials are already on order from Henshaws and include ( see pic attached at bottom for specifics )

• Tiles & T&Hs

• Tile Vents

• Ridges

• Dry Ridge Kit

• Dry Upstand

• Valleys

• Felt Support Trays

• Dry Verge

• Tile Nails
   

My house amongst trees in a forested and moss prone environment with lots of leaf fall.
 

• Are Kytun Valleys worth it in a leafy mossy area?

  • Do they shed debris well, resist moss build up compared with mortarless valley troughs?

 

• Are they compatible with Sandtoft 20/20 tiles?

  • Any issues with battens, valley board requirements etc?

  • Any recommendations for Kytun model to choose for 20/20s and any ends or connectors I should order?

 

• Install and detailing:

  • Eaves and ridge junction details for Kytun valleys

  • Jointing between lengthsm gaps and any particular recommended fixings?

  • Any recommended leaf guards, things to stop birds?

 

If Kytun is the better route, I plan to return the generic valley troughs and order the Kytun equivalents.

Anyone who has advice, experience or even some pictures to share would be great!
