I have several of the black/silver heavy duty tarps from TSC. One is over half of my chicken run. I can see some pinholes where it has rubbed against the chicken wire that spans the distance between the metal framing. It's going into its 4th winter. It is securely tied down so that it doesn't flap in the wind, but it does get sun in the summer.
The rest are over our wood piles and have more wear due to more handling, but are still in darn good shape.
