This product is aluminum. We will work on the extended description to correct.
I was advised by my builder to use this as flashing over the old ledger board behind my new deck. It's PT wood. No problems.
We do not recommend mixing metals.
Thanks for your question. You could use 1-1/4" trim nails to match the color of the flashing to attach to your shed.
Hi Sprout, it appears that this 14 in. x 50 ft. Aluminum Valley Flashing is a store exclusive item and only able to be bought in a Home Depot store.
