Functional flooring, for CHEAP!

This idea occurred to me out of necessity. We built an add on to our shed to keep our dirt bikes and riding lawn mower. It's functional but had a dirt floor that made everything a mess and was always being drug indoors or getting caked up on our shoes. I priced garage type flooring online and from sears and it ridiculously expensive. Obviously I'm not spending 250 -500 dollars on an outdoor lean to that cost 100.00 to build. So I bought a roll of cheap roofing - 40.00 at Lowes and covered the area. It took 20min to put down and it's perfect. I even have left over. It worked so well I pulled our my left over shingles from my house and painted them and layed them out to make an area for my BBQ pit. I love it!
