Hi,
My flat has a roof terrace, that doubles as the ground floor flats roof. The roof doesn't appear to be leaking into the downstairs, or at least there has been no complaints that it has. My flat is located in a block of 4, the maintenance of the flat roof is supposed to be split 4 ways. However the lady that owns 2 of the flats is flaky as they come, and there is one owner that rents his out that no matter how many attempts at contact he never replies.
There is a downpipe and hopper, where the pitched roofs drains straight onto the flat roof at present. This obviously not good as there are 3 pitches venting onto the flat roof. In heavy downpour the roof floods as it cant drain quick enough. On the far side of the roof is a drain off point to the sewers, I was thinking of replacing the existing hopper and downpipe, currently about 4 feet of it, down to the roof deck. Then run a pipe along the base of the wall to the drain off. The pipe may be to big to fit through the hole that's there, but I should be able to channel the water close enough that it shouldn't flood the whole roof. Does anybody see any reason why this wouldn't work?
In the corner where there is another drain off point the deck feels spongy when walked on, its not a large area and its been like it for years. The asphalt doesn't appear to be damaged, and again it doesn't leak. Is there any way to do something with this corner to strengthen it to save expense? I did consider using something like Thompson roof repair, then decking over it. Not ideal but nobody else wants to do anything.
The existing covering protecting the asphalt is far from great, the tiles tend to impede the water draining, however this could be due to the water from the pitched roofs. It might not be so much of an issue if my plan above works.
The tiles are lifting, and moss growing under and around them. Do you think trying to gently take them up, clean them off and sticking them back down with some kind of adhesive/mastic would work? maybe sealing the joins between them to stop dirt getting in there would work. I'm not 100% sure, but I think the tiles are made of a similar rubber to playground tiles allowing water to drain through them. Ideally they should be ditched, the roof probably redone. I'm looking to just clean it up for the minute as best I can, if it starts leaking in future then then all parties will have no option but to fork out. But in the meantime any advice on some diy fixes would be appreciated.
Thanks
Darren
