I have a flat roof...never buy a house with a flat roof because they have so many more built in problems. Long Beach Roofing has done two roofing jobs on it and they have been satisfactory. Unfortunately they have to put sealants around the drains on a regular basis due to the design of my house. They have done as good a job as anybody on my roof and balcony. They come out on time and are available on my schedule so I keep going back to them!
