Most construction consultants would turn around and run away from this Hancock Park, California apartment building complex roofing project, not us. With nearly 1,000 penetrations, roofing leaks galore, and an occupied building requiring all 120 air conditioning units to function without a shut down, commercial building inspector, Gidon R. Vardi, PhD. took on the challenge to design an effective re-roofing protocol and oversee the construction which included both a multilevel built up hot mop roof system and a raised seam metal roof. For decades, our firm has been called upon by defense and plaintiff attorneys, contractors, property owners and insurance companies to investigate, consult, manage, and provide expert witness testimony on a variety of roofing and waterproofing projects throughout the United States. Besides our home State of California we have also done so in Oregon, Washington, Arizona, Nevada, Colorado, Texas, New York.
