Hi,
I'd be very grateful for suggestions on the 'right' way to overcome this problem. I have a flat-roofed garage which joins onto my house. The gutter from the house roof has a down-pipe which ends just above the garage roof and discharges its water onto the garage roof.
There is a drainage hole in the roof, roughly below the down-pipe, and the water is supposed to run down this, down a vertical pipe in the garage and into the drain. There are some pictures you can see here:
Any ideas? Apart from the downpipe, the nearest drain or soakaway opportunity is a long way away. From the pics it looks like you could drop a pipe round the corner and down, but you can't as it would interfere with a garage backdoor and there is no drain/soakaway.
Is trying to make the hole waterproof again the best/only option? The circumference of the hole is smaller than the circumference of the drain pipe from the upper roof - obviously the best solution would be to connect the 2, but I don't suppose the bits exist to make this possible.
Any recommendations gratefully received!
Thanks,
Pete
