Can anyone tell me if a company makes a prefab flashing kit for 8"x 8" chimney block (16.75" x 16.75" square block) for a chimney exiting at the peak of a steel roof? My roof is a 9/12 pitch standing seam steel roof. Chimney exits at the peak in the middle of two seams. I found something that looks like it would work perfect from Excel chimney flashings with slight modification. It is for a Class A round chimney:

I was not able to find dimensions on this flashing yet to see if it would slide over square chimney block. My other thought was to have a heating and cooling shop that fabs sheet metal make something like this. Thanks

Why not just flash it like any other chimney?
