Hi Hicky. 
Damp and foggy here, but not actually raining. Didn't do much.
Your spicy sausage brekkie sounds good.
Thanks for the roof links. Corrugated iron is one option I'll consider. 
The roof is covered in roofing felt at the moment, but as I say, it is leaking at many points.
There's also a lean-to shed to the side of it that'll need to be done as well.
My Dad bought the garage second hand in 1992, and we re-felted the roof then. So the roof has lasted 25 years plus. He built the shed himself a few years later.
I guess the easiest thing would be to buy more roofing felt.
I don't think that vertical knife that the kids were using would be safe if they fell on it. 
But probably safer as they don't need to hold it to cut the fish.
It's a different world though.
Not much on telly tonight to interest me.
Hope Mollie had a nice 'Mothers' Day' weekend away?
