Commercial Roof Types

Denver Commercial Roofing Styles and Types

There are many different types of roofing products and systems available to commercial customers in Colorado. The most common types of commercial roofing products and styles are listed below.


EPDM rubber (ethylene propylene diene Monomer (M-class) rubber), and is used as a covering to waterproof roofs. EPDM offers a quick, clean, inexpensive solution able to be installed in a wide range of temperatures. EPDM roofing systems provide excellent UV and weather resistance as well. Systems can be installed fully adhered, mechanically fastened or ballasted. It has the benefit that it does not pollute the runoff rainwater.



A flat roof is a type of covering of a building. In contrast to the sloped form of a roof, a flat roof is horizontal or nearly horizontal. Materials that cover flat roofs typically allow the water to run off freely from a very slight inclination. Surfaces for flat roofing include EPDM, PVC, TPO, Asphalt, Modified Bitumen.


Metal roofs are great for any type of roof and are ideal in forested, moss prone, or heavy precipitation areas. Typically made up of steel, alumninum or copper, metal roofs offer some of the best protection for your home. They withstand high winds, shed snow and rain very effectively and are fire resistant. It has a long life and can even lower heating and cooling costs because it reflects heat from the sun. If properly installed a metal roof will usually last as long as the house with manufacturer warranties often lasting 50 years. It is non-combustible, corrosion resistant and metal roofing is completely recycleable. Metal roofing has superb durability and is excellent in extreme weather conditions.


Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing. PVC roofing is extremely strong, as its heat-welded seams form a permanent, watertight bond that is stronger than the membrane itself. Vinyl roofs are inherently fire resistant due to their chemical composition and have a broader range of fire ratings over common substrates. PVC has been sold for commercial roofing use for more than 40 years. Vinyl roofs provide an energy-efficient roofing option due to their inherently light coloring. A black roof can experience a temperature increase of as much as 90 degrees under the sun’s heat, while a white reflective roof typically increases only 10-25 degrees Fahrenheit. Vinyl membranes can also be used in waterproofing applications for roofing. This is a common technique used in association with green, or planted, roofs.

Stone Coated Steel

Panels made from zinc/aluminum-coated steel with acrylic gel coating. The stones are usually a natural product with a colored ceramic coating.The strength and durability of a stone coated steel roof is combined with the versatile good looks of a tile, shake or shingle exterior to give you the widest possible selection. Stone Coated Steel is energy efficient, and a tax credit are up to $500 for approved metal roof. Fire, freeze and thaw, wind resistant. 50 year warranties or longer.

Sustainable – Green

There are several sustainable green roofing options available. Metal or slate roofs can last 100 years and are energy efficient. Reflective roofs use 40% less energy for cooling and increases the resistance to UV damage. Class 4 shingles are rated to withstand hail, and will lower your insurance rates. Other factors to consider are metal roofs are recyclable, a roof with a longer warranty saves you money and the energy to make a roof that lasts 50 years is the same roof with a 15 year warranty.


TPO (Thermoplastic Polyolefin) single-ply roofing. This roofing material can be fully adhered, mechanically fastened, or ballasted. This is a popular choice for “Green” building. It is available in white, grey, and black. Using white roof material helps reduce the “heat island effect” and solar heat gain in the building. TPO roofing systems are designed for durability and to withstand extreme environmental exposure.
