What Makes Commercial Roofing Systems Different

Commercial roofs and commercial roofing systems are often all-encompassing words for the covering of a business space. When the average person pictures a commercial space, they picture large, expansive buildings that resemble Amazon warehouses. The average commercial roofing system is constructed for buildings such as these, which makes these systems different than what you would find on a residential home or home-like business structure.  Much like our post on the different between commercial roofing and its residential counterpart, there are many dissimilarities in constructing a commercial roofing system as compared to what is typically found in a more residential setting.


Commercial Roofing Systems are Built to Withstand Wear


Due to the nature of the size of the buildings, commercial roofs are often a much lesser pitch than a standard residential roof. Due to this, water will not shed as easily, therefore, the system must be more heavy-duty than asphalt shingles can provide. Asphalt shingles are meant to shed water, and water that is held on these areas can often infiltrate the roofing system. As commercial roofing systems cannot shed water as easily, they are created with a variety of different impervious materials from metal to rubber. Rubber is a much more impenetrable surface than asphalt or slate shingles, which lends its use favorably for these larger buildings. Similarly, rubber roofing is laid with a high bond that adheres directly to the roof deck, whereas asphalt shingles are nailed to the roof deck over an underlayment that protects the deck.


Commercial Structures and Accent Pieces


Fascias, soffits, and flashing are the cornerstone to a beautiful finished residential roof. In the commercial world, these items are still present but slightly different due to the nature of materials used. Flashing protects vulnerable areas of a roofing system. With commercial roofing systems that use rubber, this area must be cut to allow projections on the roof to pass through, which is where flashing is installed to prevent water from entering. This process is similar across the variety of materials used atop commercial spaces. Soffits are key to proper roof ventilation and are also present on commercial spaces but may be found in different areas due to the difference in construction. Finally, fascias also differ based on the variety of materials used, but their main purposes remain the same, to finish off the entire roof and complete a clean look.


The difference between commercial roofing systems and that of a residential roof is vast, but the purpose remains the same across the entirety of the industry: protect a structure from weather and water from entering. Commercial roofs can be done with asphalt shingles, but often due to their pitch are completed with a variety of materials that are more impervious in nature, and often higher wear. Commercial systems cannot shed water and debris; therefore, these products must be able to take a beating while maintaining their strength.
