About J&J Contractors

You know what they say – necessity is the mother of invention. That's how Christian Brothers Roofing was born, when in 1983, Jerome Cyborowski was laid off from his job at Briggs&Stratton. Eager to provide for his large and young family, he joined up with his friend and former coworker who, luckily, knew a thing or two about roofing.

We know what you're thinking: Christian Brothers Roofing? This is J&J Contractors, right? Yes, we're getting there.

With ladders, hammers, and trusty trailer in tow, Jerry and his friend worked their way through the six-month factory strike one roof at a time. And when they returned to the factory, Jerry kept running Christian Brothers Roofing all on his own, advertising “Low Cost Roofing” on painted plywood signs. Over the years, his little side business became a family business, with his wife and sons helping alongside him. With the family foundation having long since been laid, when Jerry's oldest son Jason turned nineteen, the two went into business together, becoming – you guessed it – J&J Contractors.

The father/son duo quickly climbed the ladder as home exterior experts, and by 2010, their service offerings included roofing, siding, gutters, and exterior/interior remodeling. Necessity called again, for with more services came a need for more team members, and by 2013, the once two-man team had outgrown their home office and moved into their first brick and mortar location.

We're home, now, after moving in 2019 to a beautifully remodeled, 10,000-square foot police and fire station in downtown Greendale. We have over thirty full-time employees, including dedicated project managers, designers, and administrative staff. Although we pride ourselves on offering incredible value for quality craftsmanship, we no longer advertise “Low Cost Roofing” on plywood signs. We have billboards.
