“I wanted to express my appreciation for the demonstrated professionalism exhibited by your installers. As a mechanical engineer, I have had some reasonable experience with the construction trades and was immediately impressed with the care and attention to detail shown by your crew from the first day on the job”.

At CRI Commercial we take care of your business even before a contract is signed.  With over 30 years of experience, we know that the human process, care for detail, ability to listen to each client and craft a proposal best suited to each client’s needs distinguishes us from our competitors. At no cost, pre-proposal, we visit with each potential client, inspect the work environment with the client, discuss best options, and only then offer a proposal. 


We install all types of asphalt/fiberglass shingles, cedar shake, slate and metal. Manufacturers include Certainteed, GAF, Tamko and Owings Corning. CRI is licensed and bonded in Maryland and holds certification from most major roofing manufacturers.
