Onduline Bitumen Sheet

Thank you, that's very kind.
Regarding security, It's ok as I fitted concealed hinge bolts so the doors can't be lifted out even if they removed all the hinges.
I was also considering filling the screw faces with solder just to make it very difficult, what do you think?

I have just had the shed roof (10' x 8') recovered.

The original felt when new 5 years ago was like waterproof cardboard - rubbish.

Have replaced it with the sort of felt (???) used for habitable flat roofs. Impossible to tear, much thicker than cheap bituminised cardboard, and could be torched on if required.

Given that the rubbish original covering lasted five years, I suspect this will last 10 - 15 years + - maybe more if no mechanical damage (eg: overhanging branches)
