New Jersey
Roofing, siding, and window services



Proudly serving New Jersey

Call it the tri-state trifecta. Gunner opted to enter the New Jersey market after word-of-mouth spread about the quality work and stellar customer experience we were providing in New York and Connecticut. We opened our first New Jersey office in Mahwah to serve Bergen, Passaic, and Morris counties. After countless roofing replacements, siding installations, and new window projects completed in New Jersey, Gunner has proven that we can deliver the same superior experience we have become known for everywhere we go.

Built to serve you

Founders Eddie and Andrew Prchal have made a name for Gunner by promising and then delivering professional results on home renovation projects, with a deliberate focus on customer satisfaction. Treat every job with an eye for detail and every client as though they were family. Take what many contractors would call an average remodeling job and make it exceptional.

It’s the little things. Brainstorming with the homeowner. Expanding crews to hit project deadlines. Going the extra mile to make sure the jobsite is respected, kept clean, and organized. Making sure the client is always in the loop. Integrity in the work.

This customer-first approach has paid off. We know it’s working because clients have loved the results and passed along Gunner to family, friends, and neighbors. Referrals don’t result from “OK” work.

Now we are pushing the industry further forward by offering accurate estimates from the comfort of your home.
