We've just had some work done on the roof and I have some concerns about the finish. I'd like to know if a), the concerns are valid and b) what I should be saying to the builder in terms of best practice etc.
Its the roof of a lean-to extension at the back of a terraced house. Its a small area and they replaced all the timber in order that insulation could be installed alongside a new membrane. You'll see in the photos that a little bit sticks out further as it is a store room. The tiles were to be re-used as was the leadwork. We had had some re-rendering done last year and knowing that a new roof was likely, or at least some changes to the roof, we had new leadwork installed where the roof meets the house before rendering over it. The leadwork along the parapet wall is not new.
My concerns are - and apologies for probably not having the correct terminology:
1) the finish of the leadwork. This may be cosmetic but I was expecting it to nicely tie in with the profile of the tiles, even if it was being re-used.
2) the termination of the leadwork at the end of the parapet wall. Whilst the instruction was to re-use the existing lead, they did mention that they may need a bit more, and indeed I remember say that I had some leftover from the previous work should they want to use it! It seems like this bit has just been torn/pulled round.
3) gap between the edge of the tile and the parapet wall. Its hard to tell how big this is and I don't think the tiles are meant to abut the wall exactly, but the gap looks bigger than I might have expected.
4) overhang of tiles and membrane. The membrane is untidy and is wicking water from the gutter. Not sure if this is because the tiles are overhanging too little or the membrane is too long, or something else.
5) The visible battens are getting wet at the corners, which seems like a major and fundamental issue.
6) There is nothing to stop insects etc. getting in under tiles - not sure if this is a something that this style of roof normally has though, but we did have problems before with a wasps nest under the tiles.
Other than the untidiness of the lead, you need a step ladder to see these bits properly. I'll admit that I should have got out there sooner, but I was making final checks before paying so I'm glad I've seen this now.
If there are issues here, I hopes its more of a tidy up rather than take off the whole lot of tiles. We will have a chat to the builder in the week but I would like to be informed about what I should be asking for or what hasn't been done here. There is a local roofer who we usually use, but because this package of work involved a bigger variety of things that the roofer doesn't cover, we used a building company instead.
Edit: I'll also add that this was done with BC sign off, and they seemingly didn't have any issue, but I suppose that was looking at the insulation and the structure.
