I cleaned a connie roof yesterday, one with clear glass, charged £40 inc emtpying gutters, it was a pain cos every little mark or fleck of dirt is visible from inside, anyway I did a good job but there was a few tiny bits apparently cos the customer (new regular £30 job) called today complaining that there are still marks and he's not going to pay.
How do you guys get to high stains near the ridge? I've got an Unger scraper on a pole which I used but there was I think some cement stuck on and a mark which I scrubbed and scraped for ages but it just would not shift. I cant put a ridge ladder on even if i had one cos of the plastic decoration finial etc.
Are there types of glass does anyone know that can be damaged by scraping cos it looked like there was possibly a film where the mark was and i didnt want to do any damage?
Anyway i said I would go back to do my best to get them off, I ve ordered new scraper blades to make sure theyre sharp as hell.
I'm wondering about taking on any more clear glass roofs in the future cos this job took ages for the money and I've still got hassle!
