Why Permavent was chosen:
Significant challenges were faced on how to provide advance detailing and more importantly improve structural integrity, whilst retaining the character of the roof on a nationally important Grade I Listed Building.
The specification was to restore the low pitch roof and where possible, recycle the undamaged historical Westmorland slate and replace the damaged slates with Burlington Blue slate, without impacting the character of the building. Using the unique Permavent Easy Slate system could provide this, along with it being a waterproofing solution for keeping the batten dry and protecting the roof from the wind driven rain. It also remained invisible externally and ultimately ensuring the aesthetics of the original roof features remained the same as in 1817 when the building was originally completed.
Permavent were also on hand to provide specialist roofing advice to other material suppliers.
