how do you clean your steel roof?

[ChunksterK]

The Frau and I have in the past few years had procedures roughly equivalent to both options you mention done by an independent handyman. In both cases, he charged about 40 to 50% less than you were quoted. To be fair, he did NOT uise an algaecide the time he did the more extensive version, but he did replace all the nails on our roof with screws and gaskets which we paid for separately. We get this done more often than some because Frau Chunkster hates the unsighly gunk that settles on the roof from our unpaved road.

And in case you are wondering, our guy is not taking on new customers. He can barely keep up with those he has.
