Cracks appearing in cement on the edge of a new pitched slate roof.

Anonymous user 23/02/2024 - 2.54 PM

Hi, We've just had a single-storey rear extension built on our house in London. The work was completed in October but a few weeks ago (around mid-December) we noticed that the cement along the edge of either side of the pitched roof has developed some cracks. One chunk of cement about six inches long has actually come loose near the outer edge of the roof. It shouldn't be difficult to patch it up but it's a bit worrying to see cracks in cement that's only a few months old. Can anyone advise whether this is something that we should be worried about? We still owe the builders a small amount of money for the contract and they've said they will come and fix it but we're just a bit worried that it needs to be repaired in the first place. Thanks for any advice you can give us. Mel & Kevin

Hi Its not a major issue to the roof and is a common problem that you see often to the trained eye . Their are two problems that cause this. The first is laying the cement verge in hot conditions especially with slate holding so much heat, but this would occur sooner then you have suggested. The second common mistake is bring the batten to close to the verge, this draws all the moisture from the cement and after time cracks do appear. As long as they repoint the damage verge in a neat manner at this time of year it should set with out any further problems. Traditionally speaking most slates roofs do not have a cement verge for this reason but due to modern construction a cemented verge is used. (Google slate roof verges to see).

I agree with Darren, this is nothing to be concerned about.
