The family
Rey-Crest Roofing & Waterproofing was founded in 1969 and remains family owned across three generations. The work started earlier: the owner’s father ran his own roofing company in the 1950s and 1960s. That standard — quality workmanship and direct service — still governs the company.
We are a licensed and insured commercial weatherproofing contractor with crews known for efficient, courteous, professional work. The same commitment covers replacement, waterproofing, and long-term maintenance and repair agreements.
Work spans commercial, industrial, institutional, and residential projects: churches, schools, hospitals, warehouses, hangars, aerospace facilities, high-rises, hotels, entertainment studios, financial institutions, historic buildings, and homes.
