Built a new house and hanger in 1985. 30 year GAF Timberline
asphalt shingle on the house and clear cedar siding. Morton
steel sheeted pole building for the hanger. Replaced asphalt
from storm damage once, many broken shingles over the nearly
three decades we lived there, house was way over due for a new
roof when we moved a few years ago. Had painted it a couple
of times and it needed another paint job before we could sell
it.
The all metal hanger.....was like new and probably would have
gone another 27 years, at which time I'm not gonna care what
happens to anything.
