Asphalt Shingles

Asphalt shingles are the most common type of shingle used in the USA, due to its reputation as an affordable, yet durable, roofing choice. Asphalt shingles are constructed with a fiberglass mat which is then combined with asphalt. After the mat is completed it is covered with granules. The granules are made of various minerals which add durability and color to the shingle. Great Western Roofing & Construction installs all asphalt roofing manufacturers including Tamko, Owens Corning and Versico.

Stone Coated Steel Roofing

Stone coated steel roofing is fast becoming one of the most desirable Denver roofing products. Stone coated steel roofing products are class 4 impact resistant, extremely durable, and add a sophisticated look to a home. Stone coated steel is available in multiple profiles allowing it to look like a tile, wood shake, or shingle roof. Great Western is pleased to utilize Decra tile, the original and still the best stone coated steel roofing shingle in the business.

Tile Roofing

Tile roofing products are some of the most durable roofing materials available. Available in a wide selection of colors and styles, tile roofing products can be custom tailored to match the look of any home. Tile roofing products also have some of the longest and best warranties in the industry. One of the brands we are proud to use, Boral, produces one of the largest catalogs of tile roof choices among all manufacturers in the nation—offering a color, style and look that works for every project.

The system’s low weight, durability, speed of construction and adaptability make it equally suitable for new build and re-roofing projects.
