Have you ever done foam roofing? It is a really dirty job, and the best part is that I have a great place for you to come and check it out! I am a roof consultant in South Florida and I have a job that is going on in Miami, they are applying a foam roof. The job is HUGE we have to use a Hydro Mobile Elevating system to get men, trash, and equipment on and off the roof. You have to come see this, we have 3 sky risers that overlook Miami that we are reroofing what a great scene!!!! Let me know!!!!!
