AccuSeal Roofing 1991 Ltd.

4.6(20)✓ Google-verified

AccuSeal delivers strong execution on flat and commercial roofs. Owner Ed and his crew consistently handle complex jobs on time and on budget, clean up thoroughly, and answer questions throughout. Two reviewers noted poor telephone communication, a sharp contrast to the professionalism on-site. Overall a reliable choice for commercial and residential flat roofing who makes the effort others skip.
