This post is to warn others about M. Kaufman Roofing Contractors, Inc. or as they are, know in Northeast Philadelphia - Kaufman Roofing. I am not one to complain, but I feel that I should warn the public about what I perceived to be Kaufman Roofing's lack of ethical business practices and their lack of quality workmanship. M. Kaufman Roofing was contracted to construct two new skylights, and a new roof at our row home. M. Kaufman Roofing Contractors did not call prior to showing up for this job. After they finished the job, I reviewed their work, took photos, and found that they had not correctly completed the project. The following was noted: they took debris from my roof and placed it on my neighbor's roof; they damaged the eave box for the downspout; destroyed a screen window with their ladder; did not coat the roof with an aluminum fibrated coating, they damaged the barge board and cover; used screws instead of nails; left skylights unlocked; did not paint skylights with exterior paint; did not fix soil pipe between skylights; damaged existed party box cover; did not install flashing to base of rear chimney; did not remove all job related debris and haul way from job site. I contacted M. Kaufman Roofing's Customer Service Department about these issues. Kaufman Roofing did not respond in a positive manner to any of my concerns. They refused to repair the roofing job. They were verbally abusive, rude, nasty, unhelpful, and unprofessional. I would never recommend M. Kaufman Roofing Contractors, Inc. for any roofing job. M. Kaufman Roofing Contractors are just bad news.
