Choosing the Right Commercial Roofing System for Your Property

Selecting a commercial roofing system when you own a building along the Front Range requires balancing long-term capital against the realities of local weather conditions. From severe summer hailstorms to intense winter temperature swings, your commercial roof must handle immense structural stress. Use the technical performance breakdown to compare initial investment tiers, expected lifespans, and ideal architectural applications for major flat and low-slope systems.

Depending on the needs of your building, some helpful tips when choosing a new commercial roof include: 

  • Maximize Asset Longevity: Opting for single-ply systems like TPO or PVC provides continuous, reflective protection that keeps commercial cooling costs down during high-heat summer months.
  • Capital Restoration Options: If your existing commercial roof membrane is structurally sound but suffering from minor leaks, applying a fluid-applied silicone coating system avoids expensive tear-off fees while fully restoring waterproofing coverage.
  • Heavy Foot-Traffic Solutions: Built-Up Roofing (BUR) utilizing multiple redundant asphalt plys remains the industry benchmark for commercial facilities housing extensive rooftop mechanical units or heavy maintenance schedules.

Which commercial roofing system is right for me?

Infographic by Custom Exteriors designed to help commercial building owners and asset managers understand the pros and cons of built up roofing or BUR flat roofing

Commercial roofing has a variety of systems tailored to meet your needs. Among the frontrunners are single-ply membrane systems, Modified Bitumen, and Built-up roofing systems. Here is what you need to know: 

Single-ply membrane roofing:

Single-Ply Membrane roofing is a flat roofing system. It is a single-layer profile that is typically made from rubber and attached directly to the roof. These systems comprise a single layer of thermoplastic or synthetic rubber membrane. Single-ply roofing systems are lightweight and easy to install. This often makes them a popular choice for new construction and retrofit projects alike. Standard color choices for single-ply roofing systems include white, gray, and tan. Popular manufacturers include Carlisle, Firestone, and GAF. Singly-ply roofing systems have warranties that range from 15 to 30 years.

Modified Bitumen (mod Bit) roofing:

Modified bitumen roofing systems are another popular choice for commercial buildings. These systems consist of a membrane reinforced with polyester or fiberglass and layered with a granulated cap sheet. Modified Bitumen roofing systems are known for their flexibility and ease of installation, making them a popular choice for many smaller commercial buildings. Popular manufacturers of Modified Bitumen roofing systems include Firestone, Carlisle, and Sika. Their warranties typically range from 10 to 20 years. 

Built-up (BUR) Roofing:

Built-up roofing systems are a type of flat roofing system commonly used on commercial buildings. These systems comprise multiple layers and reinforcing fabrics applied to the roof. BUR systems are known for their durability and longevity. They are often used for buildings with high foot traffic, such as hospitals and schools. Popular manufacturers of BUR systems include GAF, CertainTeed, and Johns Manville. Their warranties typically range from 10 to 20 years. 

How do I know which flat roof I need?

When choosing a flat roofing system for a commercial building, many factors must be considered. These include the intended use of the space, the climate where the building is located, and the budget for the project. BUR systems are popular for buildings with high foot traffic, while modified bitumen roofing systems are an excellent choice for new construction and retrofit, as they are lightweight and easy to install. 

The type of flat roofing system used on your commercial building will depend on various factors, and there is no one-size-fits-all solution. However, by understanding the different types of flat roofing systems available and their advantages and disadvantages, owners can make informed decisions to ensure their commercial roofs’ longevity and durability. A qualified local commercial roofing contractor will walk you through all the factors unique to your building and provide the right choice when replacing a flat roof. 

Ultimately, the choice between these roofing systems depends on factors like budget, climate, building structure, and aesthetic preferences. It’s essential to consult with a roofing professional to determine the best fit for your new commercial roof.

Colorado Commercial Roofing: Frequently Asked Questions

Commercial roofing costs vary widely based on material selection, insulation requirements, building height, and project complexity. For a standard flat or low-slope commercial building, regional averages typically fall between $6.00 and $13.00 per square foot. A straightforward single-ply membrane overlay sits at the lower end of the spectrum, while a multi-layer tear-off involving heavy mechanical structures, rigid insulation updates to meet Colorado energy codes, or complex perimeter flashing sits at the higher end.

The most common systems engineered for the local climate include:

  • TPO and PVC (Thermoplastic Membranes): Highly reflective white single-ply sheets that significantly lower cooling costs during hot summer months.
  • EPDM (Synthetic Rubber): A durable black membrane known for its exceptional flexibility and ability to handle extreme temperature drops without fracturing.
  • Modified Bitumen (Mod-Bit): A multi-layer asphalt system reinforced with fiberglass or polyester, offering excellent puncture resistance.
  • Built-Up Roofing (BUR): Traditional hot-mopped asphalt and gravel layers that create a redundant, heavy-duty barrier.
  • Fluid-Applied Silicone Coatings: A seamless elastomeric layer sprayed directly over a sound existing roof to fully restore waterproofing properties.

A professionally installed commercial roof generally lasts between 15 and 30 years. Elastomeric coatings typically provide 5 to 15 years of restored service, while heavy-duty modified bitumen and built-up systems track closer to 20 years. High-quality, correctly detailed single-ply systems like TPO and EPDM routinely deliver 25 to 30 years of continuous protection, provided they receive regular preventative maintenance.

It is estimated that a crew of professional, experienced commercial roofing contractors can take anywhere from two to four weeks to replace a commercial roof depending on the material choices, building size, and local  jurisdiction requirements.

Due to our high altitude and intense weather patterns, regional commercial properties face specific structural stresses:

  • Severe Hail Damage: High-velocity hail punctures aged or brittle membranes, shatters skylights, and dents perimeter metal flashing.
  • Damage From High Winds: High winds can break the seal on shingles and even cause them to pull off the home. This is particularly common along the foothills due to stronger wind gusts. 
  • Thermal Shock: Rapid temperature drops of 40 degrees or more within a few hours cause commercial materials to expand and contract violently, straining seams, flashings, and fasteners.
  • Ponding Water: Poor drainage design leaves standing water on a flat surface. If left unresolved for more than 48 hours, the sheer weight degrades the adhesive seams and accelerates leaks.
  • UV Degradation: Intense high-altitude solar radiation bakes low-grade materials, leading to premature cracking, blistering, and drying out.

While flat roofs maximize interior structural space and are highly cost-effective, they require active management. The primary disadvantage is their reliance on manual drainage systems. Unlike sloped roofs that shed water naturally through gravity, flat roofs depend entirely on internal drains, scuppers, and a precise structural slope to move water off the building. A single clogged drain or a slight dip in the roof deck can trap water, increasing the risk of structural deflection and leaks.

Designing an effective flat roof system requires balancing thermal performance, drainage configuration, and structural durability:

  • Structural Taper: The design must incorporate a tapered insulation layout providing a minimum slope of 1/4 inch per foot to guide water directly toward internal drains and collection scuppers.
  • Code-Compliant R-Value: The design must utilize a robust continuous layer of polyisocyanurate (polyiso) rigid insulation boards to meet strict Colorado energy efficiency codes.
  • Ballast and Fastening Profiles: The structural attachment pattern must be meticulously calculated to resist high-velocity wind-uplift pressures common along the foothills.
  • Proper Flashing Height: Roof-to-wall transitions and mechanical equipment curbs must feature flashing extending above the roof surface to protect against heavy winter snow accumulation and drifting.

The most common commercial roofing material is EPDM roofing as well as metal roofing.
