I have just had a new slate roof, but no flashing has been added to the parapet and firewalls. The roofer insists that this is a separate issue and not part of the roof. The firewalls are still leaking and he insists they need to be rerendered at an extra cost. Are parapets not part of the roof?

I live in a terraced house, there is a skew between us and next door. Next door is rented, few weeks ago the landlord said he'd had front skew repaired (we'd seen they'd been getting repairs, no idea what exactly, the scaffolding just appeared one day), the back one needed doing and would we go halves. I asked him to send me the quotes he gets, he laughed and said he'd get his builder to do it. Turns out his 'builder' is a local handy man. I've since had two roofers to look at the roof, the skew definitely needs work, but the 'builder' who did the front skew has bodged it, and carried out work on our roof at the side of the skew, that now needs fixed. Where do I stand on 1) getting next door to pay for putting the dodgy work put right, and 2) stopping them doing any more work on our side of the roof? I'm having visions of coming home one day and them up on the roof without asking again, same as when the front was done!

How can I know with certainty that a new roof ought to be replaced?

I had a roofer inspect a flat roof a couple of months ago, who then made some patch repairs using torch on felt. Another roofer cam to quote for a replacement roof today and said the felt hadn't been torched on properly and water had got underneath the add on section. The felt could be lifted up without much effort and some of the edges on the felt underneath seemed to be peeling away. He then recommended I remove all of the add on felt as this was far worse than just having the felt below it. First of all, how bad of a job is this and secondly, is this likely to have caused any major damage in two months given we've been having a lot of rain? I appreciate any answers and you taking the time to respond.

What is the cause of black and green stains on my roof?

What are asphalt composite shingles and should I purchase some? Can I install this DIY?

My neighbour has just had a new roof but upon looking from the outside and inside, it doesn’t seem to have been finished off. I have masses of daylight coming through the gap and is now a wind trap. There is a gap of which I estimate to be about 5 cm between where our tiles finish and from what I can see there isn’t a bonding gutter either. It also looks like they have used some kind of foam on their side to keep the tiles in place and create a ‘seal’ for them but nothing on mine. My roof was sound before this and I would have thought that it would be the responsibility of the roofer/neighbour to ensure that my roof would be left in tact and not open to the elements. I do have pictures from Inside the loft.

Hi, Having water ingress to upstairs box room via an air brick / vent from the roof. Looks like the roof lining material above the air brick is rotten or broken away and water is coming in around or through the tiles onto what seems to be just a tile on top of the air brick cavity hole. It is then soaking into the wall and entering the box room. There are also a couple of small punctures in the roof lining in that are but further back into the loft a little which also leak. It's almost like the tiles are having no effect. The air vent is troubling as it just has a tile as the top of the cavity ( is that normal?). Would we have to take all the tiles off and reline everything on that side of the roof or can just the bottom tiles and lining be replaced?

We have replaced our roof and the roofer has used a dry bonding gutter between ours and the adjoining roof. The neighbour does not like the appearance of the up-stand between the properties. We have tried to explain that this is the recommended method as mortar can cause other problems. I’m not sure how far this will go, but I was wondering whether the gutter could be moved on to our side of the divide without causing more issues.
