Rats eat mice Marigold and the mice know it, so if you have mice there are no predator rats. On the other had if you have food sources and no mice you will have rats. We had mouse traps in the loft in England and it came as a surprise to find several mice caught had been eaten- that's when the big traps came out.

I was told by a hedge layer that if we destroyed the mouse habitat by clearing out the bottom of the hedges, then the rats would move in. We left the grass etc in the hedge and the cats never caught a rat, it was mainly short tailed voles and the occasional wood mouse - well that's what they brought in! The next door farmer had cleared the undergrowth from the steep bank the other side of the stream- and there were rats.

How's progress on the roof, Rick?

Well,
I had a bit of a hitch on Wends because, although it was a fairly clear day, I realised that I couldn't support the green roof we are intending on the side walls alone of the extension. It gets a bit technical but if I leave the joists in that support the internal roof (way over spec for that job already) and cross them with the calculated joists to support the green roof, tying them into the wall too, then it makes a very stable box construction and gets around the potential wall stability issue (we don't really have earthquakes around here but just in case!). So I didn't get much further on Wends than deciding that and cutting the new beams to length. The soffit boards will be taller than I thought to accommodate the existing and new beams but that will be OK.
I'm making it sound like a bigger job than it is really! Only 2.5 m ish square - a giant window box!

Ooh, a green roof! Don't forget the drainage!

For Petes sake. More mice this year than ever. Hen food in an old freezer in an outside shed but even so mice in residence and traps set. Last night I was watching TV and heard a scratching noise. Glanced up at kitchen cupboard and there was a mouse. First one ever in my house. It’s war. Traps set and Amazon sending one of those ultrasonic mouse deterrents. If all else fails then it’s kitty time!

While I'm sure we've had some mice for a few years, its only this year when they have been obviously about in large numbers. I think it was the hot summer - which the insects thrived on - and so then the birds and the mice. All is fair in situations that you can't wrap in 1/2" weld mesh Hen Gen (and Chris). Like your house!!
We defiantly had one come back in the bedroom upstairs in the two days that the high frequency device wasn't plugged in and then gone again when it was (that was the type that also emits a phase shifting signal into the house wiring for which there seems to be some supporting evidence - mice being sensitive to changing magnetic fields??) They don't seem to work outdoors though (even with an extension lead to mimic house wiring) and that may be because the sound part dissipates too quickly in open space (??).
I wont forget the drainage Margaid :) Its going to be 2" of gravel for drainage, then root barrier, then 4" of soil (mixed with small brick rubble to keep the weight down.) Ive calculated it to take normal fully saturated topsoil with 170% over capacity so should be fine. The proper grade of liner has been difficult to find but a gardener friend has come up with a source.

I'm interested to know what you're going to plant on the roof, Rick. In the long drought of last summer I increased the numbers of sun-proof succulents in our dry chalky garden, and planted up several big bowls of sempervivum, which come in all sorts of colours and shapes, and grow babies round the edges with gratifying speed. You do need very sharp drainage in the soil base, in fact they seem to need practically no water-holding compost although I found they needed a mix of about 1/3 John Innes to 2/3 horticultural grit, just to give them enough soil for their roots to get a grip. My big bowls are mainly under a little roof porch over the front door, so sheltered from most of the rain in winter, but I have one outside in full rain, although I've tilted it away from contact with the ground to increase drainage. I believe you can actually buy suitable compost base material for green roofs, made from ground-up bricks etc?

I was thinking more of the downpipe to take the excess water away!

Will do!
It is south facing and without shade but easy enough to water. Just outside the bathroom window so could even use the shower head! I was thinking a mix of annuals that will be good for insects and bees and see what else blows in. I guess I could have some sempervivum in terracotta trays, bedded in, or the like in there as well.
