While repainting the facias of my 200 year old cottage I have discovered that a couple of roof tiles are broken and need replacing. Removing and replacing them seems to be a fairly staightforward job but the main problem is finding replacement slates. The size of the slates is 11 x 22 inch and a bit of internet research seems to suggest that this is not a size generally manufactured today. Any suggestions as to where to start looking for replacements, particularly as I only require 2 or 3, or am I looking at having to buy larger ones and cut them down. North Hampshire area. Many thanks.
