What kind of regular / annual maintenance is required for a residential steel roof?
I plan to install and have heard some people that there is maintenance involved.
Mine has been since 1983 and it seems to have been on yesterday. I installed myself, the screws have neoprene washers on them. never had a leak. I think the house will rot from under this roof, not soon. I did not something to him since installation.
