Hi all
I have an old (1950s?) garage roof that's prone to leaking, so I'd be glad of any advice on my options.
You can see what it's like from the photos, inside:
From on top, it looks like crumbly concrete covered in various layers of patching and gunge, (some of which I've just peeled off as it was detaching itself), with several breaks in the level.
From inside there appears to be a consistent slope, but from on top it's a much messier proposition.
Can anyone tell me a) how the roof is likely to be constructed (and what's holding those beams up?) and b) what options I have for making the thing reliably waterproof?
TIA Ken
