You may remember I had a garage roof leak issue back in 2022 which I sealed with a 10 year guaranteed sealer,
details here, well sadly I have to report that last weekend's torrential rain managed to breach the seal and the same corrugation well showed signs of seeping again this week while SWMBO was on holiday.
I decided that the best solution would be to overlay the existing roof sheets with brand new polycarbonate sheets and thus prevent the water from getting onto the old sheets altogether. I thought to myself 'Easy enough to buy new sheets and lay them on top with the securing screws going through both new and old into the beams' Then I went upstairs and looked at the roof as it is now:

- MTMO

- MTMO

- MTMO
Oh yeah, I put those boards down for access and the ivy has gone potty, and the sealed gulley still looks sealed!! Maybe sheeting over the top just isn't the way to go, time for a completely new roof has to be the right way. Now that means emptying the upper shelves and maybe the whole garage, clearing back all the ivy, getting the boards off, removing the flashing and the old sheets, possibly adding a couple of new beams, installing the new roofing sheets and flashing and finally possibly refitting the walking boards and then refilling the garage, though there is nowhere to put the stuff while the job is done, maybe 3-4 days or so? Total material costs around the £300 mark. I am going away next week so no chance to do it before mid October by which time the weather may not be helpful. Hmmm!
Pondering on that it seemed to me that a temporary solution to overcome the problem is required to see us through the winter and then put on the new roof in June next year. With that in mind, and not really wanting to get up there and paint more sealer over the sealer I decided the best approach would be to accept the leak and arrange to catch the water that came through and divert it out of the garage to a safe place for drainage. Hence I purchase a 'dog bath' with built in drain tap and installed it as you can see below, the tank itself is supported by steel hooks through the top and the ladder beneath which is very secure:

- Tank in situ

- The drain valve

- Outlet position

- Hose route

- Hose exit
Having completed the install I filled the tank until the drain came into operation and checked it is leak free. I just need to insert an appropriate material into the bottom of the tank to bring the bottom water level in line with the outlet which is 12mm above the tank bottom so as to prevent 12mm of water going stagnant inside the tank!!
