There are four outbuildings along with a cool down shed on Christian's farm, and several were in desperate need of roof repairs when he bought this farm. We immediately re-roofed the large horse barn ourselves, tarped the stone smoke house roof, and recently hired roofers for the garage barn. The cool down shed roof we will rebuild with 4-ply plywood and H clips, 15 lb. tar paper, and pewter gray high definition shingles which matches the garage barn roof. All can be bought at Home Depot.
First several rafters and fascia boards will be replaced. Later some wall boards will be repaired as well. The proportions and roof pitch of this structure seem just right to me.
Below are the horse barn roof we replaced with a metal roof after removing the old plywood and asphalt one, and a team of 10 men re-roofing the garage barn with repaired plywood and high definition asphalt shingles.
