Value is more than a word to us. We believe Value is where an efficient price and high quality intersect. Our 35+ years of experience have proven to us that the cheapest products and installers rarely get the job done right. Similarly, we believe it serves no customer well to offer a higher priced material without a worthwhile and corresponding increase in performance and/or longevity. We focus on the entire roof system, from decking and critical underlayment, sealing penetrations, edgings and confirming ventilation, as well the roofing top layer visible to all. The systems must each be of high quality but, more importantly, must also work together as a system; and the most important part of the system is the security of using CJ Roofing as your roofer of choice!

Quality and Value is delivered by CJ Roofing in our attention to detail, factory trained installers, on-site quality control, and a dedication to customer satisfaction. We provide security to our customers with our insurance coverage of both our workers and your property, giving you total peace of mind. We guarantee the quality of our work and provide the 5 year CJR workmanship warranty to all our customers.
