Each ProWash Trailer System™ is designed from the ground up around the principle of increased efficiency and production. From the moment they arrive on the job site, these trailer systems begin working to multiply your workforce and grow your profits. We have years of experience in the commercial roofing industry, and if there’s something that can go wrong on the job site, we’ve probably experienced it, too. We developed the ProWash Trailer System™ as a response to these problems, working from the ground up to build a complete roof washing system to eliminate many of these headaches. The ProWash Trailer System™ is battle-tested and has proven itself to increase on-site production and increase profits.
