Slate Roofing
Natural slate is the pinnacle of roofing materials—a premium stone offering one hundred years of durability and extreme fire resistance.

John and his crew did all that I ask, I added several more tasks , did excellent work, did everything that he promised. I would highly recommend him, have used him for several other things since. I’ve recommended him to neighbors, friends and family, he doesn’t disappoint

I used Preferred Contracting for a number of projects when I bought my new house and they were absolutely fantastic. They installed my new click lock vinyl floors, replaced my old windows with affordable, but energy efficient new ones and installed an exhaust fan in my bathroom that didn't previously have one. John and his team were fast, affordable and provided quality work!

We hired John Zolko at Preferred Contracting Services to completely rebuild our house’s original Victorian box gutters. He worked with our budget (and we changed the scope of the project a couple times). He and his crew were honest and hard-working. And fast! The whole thing was done in two weeks! And the craftsmanship is just beautiful.

John and his team are wonderful. This is a family small business which John has owned and operated for decades, so his experience is unsurpassed. John will hang from his gutters to demonstrate their strength, and he applies the same confidence in all of his work given that he's simply been doing this for so long that he knows all of the ins and outs. Experience counts in this business. Highly recommended

Good luck getting in touch with these guys. Calling their number puts you through a painful list of questions about free roadside assistance, free trips to Cancun, and free pet grooming. All I want is a quote on a little roofing project.
Their web site has a form to contact them via email, but that doesn't work.
On to the next guy!
