Commercial Flat Roofing Systems

There Are Many Options Available for Commercial and Industrial Flat Roofing

Commercial and industrial roofing systems

In the construction of commercial and industrial buildings/complexes, it is a commonly accepted practice to install some type of flat roofing system.  For the owners and/or property managers of these properties, there are some fundamentally sound reasons for employing these systems rather than the sloped or pitched roofs that are traditionally associated with private homes and residences.

The most tangible advantages of commercial or industrial flat roofing pertain to cost or affordability:

  • Easier to install – leads to lower initial installation costs
  • Maintenance and repair costs are usually lower as a rule
  • Longer-lasting – extends time before replacement needed

Other benefits typically associated with flat roofs in contrast to pitched surfaces include:

  • Easily accessible for maintenance and/or repair purposes
  • Adaptability for the installation of green roofing initiatives
  • Less wind resistance – reduces potential for storm damage
  • Provides space to accommodate equipment such as AC units
  • Energy efficiency – less unused space under roof to heat/cool

When installing commercial flat roofing or replacing/upgrading an existing flat roof, there are several options relative to the choice of material, for which costs will vary based on:

  • Composition of the material
  • Size/area of the roof surface
  • Installation time and method

In terms of roofing materials and their modes of installation, the commonly available alternatives consist of the following, listed in no particular order:

  • Built-Up Roofing (BUR)
    • Also known as traditional-tar-and-gravel roofs
    • Three alternating layers of waterproofing and hot tar
    • Overlaid with a layer of stone
  • Single-Ply Membranes
    • EPDM (ethylene propylene diene monomer)
    • Made from synthetic rubber – much easier to install than BUR
    • Usually installed either by an adhesive or mechanical fasteners
    • Can be loose-laid (secured along the edges; seams tape-sealed)
    • TPO (thermoplastic olefin)
    • Less expensive to install than BUR; significantly lighter in weight
    • Heat-reflective properties lower energy consumption in summer
    • Can be installed over existing roofs (based on certain conditions)
    • PVC (polyvinyl chloride)
    • Contain plasticizers and stabilizers for improved flexibility
    • Installation methods parallel those noted for EPDM roofing
    • Puncture resistant – reinforced with polyester or fiberglass
  • Modified Bitumen Membranes
    • SBS (styrene-butadiene-styrene)
    • Commonly applied in rolls that include a self-adhering backing
    • Has an elastic quality – better resistance against aging, weathering
    • Heat-reflective material – reduces energy costs during the summer
    • APP (atactic polypropylene)
    • In rolls with self-adhering backing – applied by torch or heat-welded
    • Has a plastic quality – improved UV resistance, low-temp flexibility
    • High resiliency – long-lasting performance; resistance to splits/tears

While all of these respective systems offer their own set of distinct advantages/benefits, some options may be preferred or favoured in certain situations depending on structural needs, building owner preference, and individual circumstances.
