Hello Is the property going to remain a cow shed or is it becoming a living space? If it remains a cow shed then there is no problem in replicating what you already have, that is opening up the 'perps' of the slate to allow extra ventilation. However this system may well allow wind blown rain or snow to pentrate into the roof space under certain conditions, but being a cow shed, that wouldn't really matter if it wasn't too often. Open slating wouldn't be recommended on a pitched roof above a living space for the reasons above. Open slating loses 'side-lap'. Having the correct minimum side-lap

Hello, I am able to advise on pitched roofing problems expecially involving natural slate and lead. I have been working with slate & lead roofs for over 25 years as a slater, leadworker, contractor, merchant and consultant. I have a long list of credentials, and strive to offer 'Plain English' advice.
