Roofs come in many different shapes and sizes. 

At Columbia Roofing, Inc, we install all types of asphalt/fiberglass shingles, cedar shake, slate and metal for both commercial and residential. Manufacturers include Certainteed, GAF Roofing Shingles, Tamko andOwens Corning.

CRI is licensed and bonded in Maryland and holds certification from most major roofing manufacturers. We are also members of The National Roofing Contractors Association.

From CertainTeed: ask about our new product from CertainTeed – Highland Slate! A durable, beautiful color-blended line of shingles with the widest array of colors to suit any trim, stucco or siding color. Manufactured with self-sealing adhesive strips and a wide nailing zone, CertainTeed is larger than competitors for ease of installation so your roofing job is complete in no time.

And also ask about another new CertainTeed shingle called The Patriot! Or more choices available from our other fine manufacturers including Owens Corning, Tamko, and GAF.
