Identifying Your Commercial Roof Type

Determining the type of commercial roof you have is essential for maintenance, repair, or replacement decisions. The most common types of commercial roofing systems include:

  • Built-Up Roofing (BUR)
  • Modified Bitumen
  • Single-Ply Membranes (TPO, PVC, EPDM)
  • Metal Roofing
  • Green Roofs
  • Spray Foam Roofing

Each type has distinct characteristics, benefits, and drawbacks that can influence your choices based on the building’s needs and local climate conditions.

Built-Up Roofing (BUR)

Built-Up Roofing consists of multiple layers of bitumen and reinforcing fabrics, creating a durable and waterproof surface. It is often finished with a layer of gravel or a reflective coating.

Advantages:

  • Excellent waterproofing capabilities
  • Long lifespan (typically 20-30 years)
  • Suitable for flat or low-slope roofs

Disadvantages:

  • Heavier than other roofing types
  • Installation can be time-consuming and labor-intensive

Modified Bitumen

Modified Bitumen roofs are an evolution of BUR, utilizing polymer-modified asphalt for enhanced flexibility and durability. They can be installed using torch-down, cold adhesive, or self-adhering methods.

Advantages:

  • Enhanced resistance to UV rays and extreme weather
  • Easier to repair than traditional BUR systems

Disadvantages:

  • Can be susceptible to punctures
  • Installation requires skilled labor

Single-Ply Membranes

Single-ply membranes, including TPO, PVC, and EPDM, are lightweight, flexible sheets that can be mechanically fastened, ballasted, or adhered to the roof deck.

Type Material Characteristics
TPO Thermoplastic Polyolefin Energy-efficient, white reflective surface
PVC Polyvinyl Chloride Strong, puncture-resistant, good for chemical resistance
EPDM Ethylene Propylene Diene Monomer Excellent weather resistance, black or white options

Advantages:

  • Quick and straightforward installation
  • Low maintenance requirements
  • Energy-efficient options available

Disadvantages:

  • Lifespan varies (15-30 years)
  • Some types can be less fire-resistant

Metal Roofing

Metal roofs, often made from aluminum, steel, or copper, are known for their longevity and durability. They can be installed as standing seam or corrugated panels.

Advantages:

  • Extremely long lifespan (50 years or more)
  • Reflects heat, improving energy efficiency

Disadvantages:

  • Higher initial cost compared to other roofing types
  • Requires proper installation to prevent leaks

Green Roofs

Green roofs incorporate vegetation and soil layers, providing insulation and stormwater management benefits. They are particularly valued in urban settings for their environmental contributions.

Advantages:

  • Reduces heat island effect in urban areas
  • Improves air quality and biodiversity

Disadvantages:

  • Higher upfront costs and structural considerations
  • Requires more maintenance than traditional roofing systems

Spray Foam Roofing

Spray foam roofing involves applying a mixture of isocyanate and polyol resin that expands on application, forming a solid, seamless layer.

Advantages:

  • Provides excellent insulation properties
  • Seamless application reduces the risk of leaks

Disadvantages:

  • Sensitive to UV exposure without proper coating
  • Requires professional installation for best results

Conclusion on Roof Type Identification

Understanding your commercial roof type allows you to make informed decisions about maintenance, energy efficiency, and overall building performance. By recognizing the distinct features of each roofing system, you can tailor your approach to upkeep and repairs, ensuring your commercial property remains in optimal condition.

Identifying Your Commercial Roof Type

Determining the type of commercial roof you have is crucial for maintenance and repair decisions. Various factors, including the material, design, and installation method, play a role in identifying your roof type.

Common Types of Commercial Roofs

Here are the most prevalent commercial roof types found in Lancaster:

  • Flat Roofs
  • Built-Up Roofing (BUR): Layers of asphalt and roofing felt, often topped with gravel.
  • Modified Bitumen: A single-ply roofing system that can be torch-applied or cold-adhered.
  • TPO (Thermoplastic Olefin): A single-ply membrane known for energy efficiency and durability.
  • EPDM (Ethylene Propylene Diene Monomer): A rubber roofing membrane, often black, providing excellent weather resistance.
  • Pitched Roofs
  • Metal Roofing: Usually made of steel or aluminum, offering longevity and durability.
  • Shingle Roofing: Asphalt or fiberglass shingles, commonly used in lower-pitched commercial applications.
  • Slate or Tile Roofing: High-end options that offer aesthetic appeal and longevity.

Factors to Consider When Identifying Your Roof

Several characteristics can help you identify the specific type of roof you have:

  • Material Composition: Look at the surface material. Is it rubber, metal, or asphalt?
  • Roof Pitch: Measure the angle of the roof. Flat roofs typically have a pitch of less than 2:12, while pitched roofs have steeper angles.
  • Insulation Type: Check if your roof has insulation layers, which can indicate specific roofing systems.
  • Drainage System: Assess how water drains off your roof. Does it use scuppers, gutters, or internal drains?

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
