Built-Up Roofing

Built Up roofing systems have been in use in the United States for over 100 years. Built-Up roofing systems use a highly reliable waterproof membrane fabricated with layers of bitumen, and alternating with plies of reinforcing felts. The redundant layers provide outstanding resistance to water and weather. Two applications exist for this system: Hot-Applied and Cold-Applied.


Client Testimonials

"I'd like to formally thank the Service Department at Greenwood Industries for their professionalism and dedication to their work.  From the first call we made to you as a new customer, I could tell you were dedicated to great service.  After that first call, your technician called to confirm his anticipated arrival time, and actually arrived on time!  All of the various roof leaks were satisfactorily repaired and you even called the next day to check on the performance of those repairs. As a Master Electrician who has worked in a service role for many years, and now as acting Facility Manager for one of the Commonwealth's most critical buildings, it was refreshing to see that same respect, values, and professional displayed by your techs that I remember from years past.  You just don't see this kind of customer service as often as we'd like anymore."
