Hi we have a major problem. We had an extension built approx 2 years ago and just had the buildings inspector round to perform the final checks and sign-off. On the day all seemed well and he went away happy.
However a couple of days after the visit we received a letter saying that the completion certificate couldn't be issued because the roof tiles need to be replaced as they do not adhere to the British Standard for slating. The roof was completed using 250mm x 400mm slates and apparently this size of slate should not be used on roofs with a pitch of less than 30 degrees (the roof is 20 degrees).
The architects drawing specified that Redland Cambrian slate tiles be used and should be laid at a pitch of approximately 22.5 degrees. The tiles used are slate, but don't think they are Redland Cambrian. This has put us in an awkward situation and expect this will result in a bun fight of some sort.
Many thanks for reading and grateful for any advice.
