I reckon honestly I would earn 50% less than now,yeah the back aches from time to time but I now factor in £60-80 a month in massages etc lol. I get my ladder off about 4-5 times a month for the odd flat roof as said before but this year I'm aiming to get that down to zero because I'm going to say unless I can do it dr inside I'll do it next time when your in,the fact is off ladders it's not the first couple of days in the week it's from Wednesday onwards you feel it and that's when your daily rate suffers. I can do the same most days with the pole and on certain work I don't feel as though I've done much although I earn very good money,sometimes 3-4 times the ladder rate.
