I was just reading a little blurb for a UK company which stated that in Scotland roofs were covered with sarking board over which underslating felt is laid with a COUNTER BATTEN beneath the roofing battens.
I am going to replace a batten only system with a solid roof sheath , felt covered, with slate for my location (PA) and wondered why there was an extra step involved in the above description. Some question about roof breathability over solid decking? Or needless concern? |

The roofs I saw in Scotland had the slate nailed directly to the sarking (boards) without battens. Batten roofing is an English/Welsh tradition rather than a Scottish one. The purpose of the sarking (roof decking boards) is to provide a nailing base for the slate as an alternative to battens.

with reference to your question what is a counter battens purpose its purpose is to lift the battens off the felt so the roof instalation can breath from ridge to eave and to stop a water trap forming behind battens it also has many other benifits like higher upstands at valleys side slips e. t . c holds the felt down wile roof instalation is taking place, yes scottish slating practice is slating direct on to a sarked roof but this is changing and we are starting to see more slating on to battens in the last ten years |
