Stone-Coated Metal Shingles and Tiles

Stone-coated metal shingles and tiles are an exciting, somewhat new roofing product. They’re similar to traditional asphalt shingles, except instead of a fiberglass foundation, it’s metal. Why? Metal is much more durable than fiberglass. Asphalt shingles last, on average, 25-30 years. Metal, on the other hand, lasts 70 years or more. As a result, metal often costs less in the long run, even though it costs more initially. Stone-coated metal roofing are made to resemble traditional roofing products, such as barrel tiles, traditional shingles, and wood shake.

Concrete and Clay Tiles

If you’re looking for a truly old-world look, you want real clay or concrete roofing tiles. Concrete tiles are available in a wide variety of styles, including Class-4 hail rated tiles that resemble real stone slate, authentic-looking Spanish barrel tiles, and authentically replicated hand-split cedar shake. If you’re a purist and want the real deal, clay tiles are for you. Clay tiles are available in a number of profiles, such as S tiles, 2-Piece Mission, Romano Pans, and more. In additional, clay tiles help to cool your home, thanks to their relatively high solar reflectivity and heat emittance properties.

Standing Seam

If you’re interested in standing apart from your neighbors, consider standing seam metal roofing. Not only is it extremely durable and long-lasting, it does the best job at lowering your summer cooling bill. That’s because it does the best job of reflecting heat and releasing absorded heat. No other roofing product is more green/eco-friendly than standing seam or corrugated/PBC metal roofing.

Corrugated/PBC metal roofing might be the ultimate roof. It has all the same benefits as standing seam: is recyclable, comes in dozens colors, highly durable and long-lasting, and low long-term cost. But it’s also the most hail resistant roof. That’s because of its wavy pattern. Flat surfaces have a tendency to dent more easily. Corrugated/PBC doesn’t have any flat surfaces.

Modified Bitumen (ModBit)

Modified Bitumen is basically a large, rolled asphalt shingle. ModBit is often used on low-sloped residential roofs when the primary material is asphalt shingles. It comes in a small range of popular colors to coordinate with asphalt shingles.

Frederick Commercial Roof Installation

Since we’re a complete Frederick, CO, roofing company, we also offer commercial roof coverings, such as these PVC, TPO, and EPDM.

  • PVC
  • TPO
  • EPDM

Single-ply roofing systems aren’t just for commercial businesses. They’re really for any low-sloped roof. For example, we often install EPDM onto detached garages and home additions.


If you have a restaurant in Frederick, PVC is what you need. That’s because of it’s ability to resist fat, grease, and oil. How does grease get into your roof? Via the ventilation system above the cooktops in the kitchen. PVC is a type of plastic. PVC holds-up very well to extreme weather. It’s also inherently fire-resistant and energy efficient. However, PVC is, unfortunately, the most expensive and the shortest-lived of the single-ply roofing systems we offer.

If you don’t have a restaurant, TPO might be a good choice for your Frederick business. It’s more affordable than PVC and longer-lasting. TPO is popular among those in manufacturing, warehouses, department stores, office buildings, condos, medical and dental offices, hotels and motels. TPO is also recyclable, unlike PVC.


EPDM is rubber. As mentioned above, it’s commonly found on home additions and detached garages. Although it’s also found on commercial buildings. Oddly enough, EPDM is the least expensive single-ply roofing system and the longest-lasting. Since EPDM is basically rubber, hail stones bounce right off. If you have a service center, department store, medical facility, or the like, an EPDM roof might be for you.
