        Very satisfied with this purchase. We used these panels to roof a pergola. The quality of the panels is excellent and the dimensions are perfect. These will last for a very long time. It seems excessive of the number of screws the manufacturer recommends but I followed it anyway.

        After waiting over 3 weeks for delivery of a planned install the material was damaged. All 10 pieces had damage from the top one to the bottom. They refuse to ship to home so the handing of product is not secure I feel.

        I priced this exact product from a local, family owned, metal supply company. Their prices are one quarter of Home Depot. I highly recommend shopping/pricing from your local metal supply companies.

          Perfect roofing material for any project (mine was a garden shed). Comes in various lengths for most projects. Don't forget the correct rubber gasketed screws and end closure gaskets for installation.

          We ordered 10 pieces to make a roof for our pergola that was being rebuilt. One of the pieces in the order was short, it was only a few feet long, leaving us with 9 full 16 foot pieces instead of 10. We called Home Depot to see if we could get just the one missing piece sent out, we could have returned the short one, but apparently due to the policy of the company they buy their tin roof pieces from, we had to return our whole order and reorder it. This was not only a major inconvenience, but has delayed our project by at least month. It’s been several weeks and we are still waiting for the new order to come in. Home Depot gave us a discount on the re-order for our inconvenience, but honestly I would have rather been able to continue our project and just be waiting on our one piece to come in to complete it. So while I won’t say don’t buy from Home Depot (they tried to make it right), I would caution that on pick up of this type of item, don’t count from the end of the pieces, untie the order and lift each piece to make sure you are getting the correct length on each one. Other than that, we liked the product and the color (Gray) that we chose, have yet to see how the re-order and installation goes.

          Good product, would use again.
          Good product. Used as siding, it's a little thin and you must support it every 3feet or so to make sure it is strong, otherwise you will end up like Ann ... read her review, that's what happens when you don't screw it down per the companies recommendation.
