In the process of getting quotes for steel roof to go over 1 layer of shingles. Location is southern NH.
Low quote is for standing seam ABC manufacturer, SL-16 panels. 29 guage, sheet is fastened to roof.
Higher quality (and 50% more) is for 24 guage, cut at site from roll, sheets are held down by clips, clips are fastened to roof, also standing seam.
Any opinions on either of these?
I will need to walk on roof at times to clean chimney and paint.
