Caution required.

I thought I'd climb up on the roof before the day got too hot so I could clear out the grass growing in the guttering, however much to my surprise and dismay the tiny bit of dew still on the roof made it extremely slippery.
Shortly after snapping this shot I had a big whoopsie and the poor camera took yet another tumble bouncing a fair distance along the roof but without sustaining extra damage.
After becoming aware of how slippery the roof was I carried on in a much more cautious manner and actually found it quite a difficult job, and it was very difficult for me to drag my body away from the edge after finishing.
