Commercial Roof Clean, Large High School


General contractor/project manager



Only 360,000 sq ft to go! Haha


Why is it black and white? Can you post a close up shot?
Are you taking the black off?


great question, the EPDM is the black and my best guess is the white was a primer or some kind of sealant they had put on in the past. The contractor is not for sure what it is exactly but the scope only requires to do chemical application and remove the top layer of film from membrane. They are not expecting all the “primer” to come up but have mentioned that if it peels up when pressure washing just go with it. Had some concerns with that but narrowed it down in contract. Hardest part about this job is the 240 A/C units :tired_face:



thanks for the reply
