I have aluminum siding on my house, it was built in 1979 and have some small areas that need repair. I spend a good deal of time trying to find someone who still makes aluminum siding so I could replace small areas and even change a few things, such as add trim around new vinyl windows. I had no luck for aluminum siding at all. I did however, run into plenty of advertisements for vinyl siding. Sears, Lowe's, Home Depot, Siding specialists, but I'm afraid I did not pay attention to the size of siding. Sorry.
