Grouted roof
A grouted roof is a form of slate roof. It has developed as a form of vernacular architecture associated with the West coast of the British Isles.
A grouted roof is distinguished by having an overall coat of a cement render.
== Conventional slate roofs ==
A conventional slate roof consists of thin slates, hung over wooden laths. Slates are hung in place by wooden pegs through a hole at the top of each slate. The peg stops the slate slipping downwards, the weight of the slates above it hold the slate down. Later roofs replaced the peg by an iron nail driven into the lath, but the nail is always primarily a hook and it is the weight of the slates above that hold the roof covering down onto the frame. Lead nails were also used, long enough to be bent over the laths from the inside. In time these developed into strips cut from lead sheet.
Such roofs are common and are particularly well known in Wales, where the high quality slate from North Wales was exported world-wide. As the slate was of high quality it could be split very thinly by experts and so gave a lightweight roof covering that was still strong and long-lasting against harsh weather. Where local slate was used instead, this was of lower quality than Snowdonia slate and so the roof design may have been less successful. In particular, lower quality slate must be cut to thicker, heavier slates to retain adequate strength, so giving a roof of much greater weight.
