all i can say, i have posted here for other peoples opinions, you will note , i have raised concerns myself which is good h&S practice
safecontractor would welcome me questioning an on site Nebosh trained H&S guy, responsible for 1000 buildings allowing me on the roof, my method statement and risk assessment satisfied him enough to allow me.
He didnt seem to have any concerns other than be careful.
I am no expert, i try to learn all the time, i question H&S at every turn, I have committed myself to Chas, Safecontractor and IOSH managing safely, but unfortunately all this doesn't stop you encountering problems, and stopping to think occassionally. Even Nebosh trained guys dont always get it right.
There is so much conflicting advice to roof work, i guess the only way is to avoid roof work altogether, unfortunately in the commercial worls this is easier said than done.
