This is the roofing school inside the warehouse at the back of my office.
I love these little pitched roof skeletons - used to train roofers in safe and comfortable conditions before they are required to face the elements while working at height - full size doll-houses with neither the dolls nor the house.
There are some flat roof training bays too, but they have so much less gotcha-factor.
It's sad that I don't qualify for any kind of training whatsoever, but there it is.
We're back in overtime season and I will be racking up the hours at home this weekend utilising the skills I paid to learn 29 years ago.
I'm just grateful that my employers aren't begging for 21st Century software skills.
