free rubber roofing

I don't know if this belongs in this forum, but here is a tip for all you Wofati/underground house builders. Commercial roofers, at least in this area, use a very thick durable type of rubber for roofing. When a large commercial building has the roof rebuilt, usually due to a tiny leak somewhere, all the rubber roofing is pulled off and replaced with new rubber. The rubber that is pulled off is as good as new and free for the taking. The life expectancy is measured in decades. I recently got 40,000 sq ft for free and the roofers were kind enough to load it on the trailer for me with their crane. I don't know how much that amount would cost but I'm guessing it would be expensive.

Wow, that is an awesome idea! Old Rubber roofing (aka EPDM) is incredibly useful for lots of stuff from covering wood piles to lining ponds to putting under buildings or trailers to save the bottoms from moisture issues. Moisture will constantly be emitted from the ground beneath buildings or trailers or autos unless there is some sort of barrier.

Sounds like what I need to find for a pond liner

Great tip. They probably have to pay a tonnage fee at the landfill to get rid of it.
