Hopefully, this is a silly question, but ...
Yesterday, we had a job replacing a couple of old triple-track storm windows. The home owner couldn't be home. "Fine," we said. "They are over a shed roof on the front of the house. We'll just climb up there and replace them. Nobody has to be around."
When we crawled up the ladder, we found that the roof was a rubber roof. The roof was completely dry, but when I got on it, it was extremely slippery. I definitely didn't feel safe at all on it and we aborted the job. It seemed like there was an oxidized coating on the roofing material.
We don't do a lot of work on roofs and this was the first time I had noticed a rubber roof was this slippery ... of course, it had a bit more pitch than others I've been on in the past.
To the question(s) ...
Is there anyway to clean this roof (even in a limited area) in order to make it less slippery?
Was I wearing the wrong shoes (boots)? Should I have put on golf spikes?
Without a better solution, I guess I'll have to do the job by hanging out the windows.
