comment Leaking flat roof
This was the problem! I used careful heat and pliers to gently bend all the flattened seams back to standing up straight. There have been several heavy rains since with no leaks at all. Thanks!

comment How can I get a 60 Hz refrigerator to work on a 50 Hz system?
I would love to understand this better. Please define "total structural loading" and "surface loading" in this context. Also, I haven't been to Europe, but I'd be surprised if European kitchen floors could not hold 147 kg. That's only the weight of two moderately-large people.

The first and second sentence of (4) would appear to contradict each other.

Do I need to worry at all about possibly melting the lead with a torch?

comment Leaking flat roof
Your answer is appealing because of Occam’s Razor (the simplest explanation tends to be correct), but how far do you expect a leak at the gutter could travel uphill away from the gutter? The leaks are in a few spots throughout the area under the roof, some of which are quite far (and thus elevated) from the gutter. The slope isn’t extreme, probably only 2%, but still…

comment How should I build a wooden gate?
It can’t slide as there are walls on both sides (the concrete column is part of a wall). A swing gate is what I want to build. It could split in the middle but I don’t know if it’s a good idea to hang anything off the brick wall, as it’s quite old, single-leaf brick infill and I’m not sure what sort of load it would carry.

The concrete column is about five metres tall and the brick wall about three metres, so that shouldn't be an issue.

Tall enough to prevent opportunistic climbers, I guess. If someone has a ladder I'm not expecting to stop them, but I don't want anyone vaulting over it. So I guess perhaps 2m?

comment Is it safe to drill small holes in load-bearing concrete beams for expansion bolts?
@Chris Into the side.

Correct me if I'm wrong, but the builders would have been somewhat ahead of their time to be using pre-stressed beams in the 1960s, wouldn't they?

comment How do I safely install a pole/mast on our roof?
It will extend two metres above the top concrete column mounting point (one metre of the pole will be along the column, two metres above it). We will end up mounting several 50cm+ dishes to it. Our area has occasional high wind.

The column doesn't project into the air like a chimney, it has brick infill on two sides of it and a room on the third side. I have access to only one face for fixing the mast. These devices look great but appear to require access to all four faces of the column.

I don't have access to all four faces of the beam, so I can't go around it.
