Commercial Roofing Contractor in Philadelphia, PA

Zenith is a commercial roofing contractor working across Philadelphia, Pennsylvania. Philadelphia has some of the oldest commercial roof assemblies we touch: row-commercial and converted mill buildings with layer after layer of built-up roofing, coal-tar pitch, and rolled asphalt, often over wood plank decks. Tear-offs regularly reveal saturated insulation and deck repair nobody budgeted for, so we probe and core before quoting. The city's flat-roof density plus intense summer heat island makes reflective membranes and coatings an easy win. Work permits through Philadelphia's Department of Licenses and Inspections under the PA Uniform Construction Code, and the Cool Roof requirement pushes low-slope replacements toward high-reflectance membranes.
