Use this on the of my roof for my generator box worked perfect. Whatever you do, don't let it the sticky sides touch each other. Or you'll never get it apart..

We had a leak on the roof of our camper. Removed damage roof, replace any damaged wood and used this to cover wood. Works great!

I used it to wrap a wood support beam in contact with the ground of my enclosed sun porch that the contractor installed that was not wolmanized. I did not want to use wood preservative because it was would have been more difficult to install and its adjacent to my tomato patch.

I've used it for years, the more practice and skill you have the better. Per sq expensive but you can install it directly to plywood or old metal, still recommend hiring a pro roofer to get the most use out of it. Don't recommend it for a flat surface though.

I installed this on my bus on top of plywood. My suggestion is do not use asphalt primer like they recommend. It is messy and can cause bubbles which can lead to wear and tear. Also it cause indentions when you step on it which can allow water to puddle. So, do not use that stuff. What you should use, especially for the diy-er is the glue they sell for it. It will lay flatter and adhere better. Also, do not have anything sharp in your pockets!! It's not easily cut, but if you slide on it with a knife in your pocket it might gash into it. Lastly, if you're worried about the edges I would recommend putting the 6" version of this on the edges with the glue. It holds well without that, but with my bus driving on the interstate, I wanted to secure the edges better. Other than that this stuff is awesome and easy to use. I'll be using this in the future on other projects and would recommend it to friends and family.
