When it comes to roofing, there is a big difference between commercial and residential. While the overall purpose of both is the same — providing protection from the elements — there are several key differences in materials, installation, and maintenance. Here's a closer look at how commercial roofing differs from residential.
When it comes to commercial roofing versus residential, the type of material used is one major difference. An average home typically has a roof with a pitch between 4/12 and 9/12 and is covered in asphalt shingles. On the other hand, it is common for commercial buildings to have flat roofs, usually as a cost-saving measure. To avoid leaks, commercial roofers often use modified bitumen or something similar for waterproofing purposes. Bitumen is composed of asphalt and rubberized solvents that form a thick layer when applied correctly. It is a highly durable product that can last many years.
The installation process for commercial roofing also differs from residential in many ways. Commercial buildings tend to have much larger surface areas than homes, so contractors usually install large quantities of modified bitumen rather than individual shingles or tiles, as you might find on a residential property. Additionally, installation can be more complicated due to building size, overall shape, and existing structures, such as rooftop air conditioning units and parapet walls. The process itself requires specialized techniques, which only experienced commercial roofers know how to do properly.
Finally, while residential roofers need to be safe, the Occupational Safety and Health Administration (OSHA) has much stricter safety requirements for commercial roofers. These include fall prevention measures, such as guardrails and specialized safety harnesses, as well as using the right equipment for specific jobs.
Maintenance and Repair Requirements
Maintenance requirements for a commercial roof also have additional considerations for business owners to keep in mind. For example, flat roofs have no natural slope for water runoff like pitched roofs, so they require regular inspections and repairs if any leaks develop. Commercial buildings are also more likely to attract algae and mildew growth due to their larger surface area. They should be checked regularly by an experienced commercial contractor who can spot potential problems before they become serious.
Commercial roofing differs significantly from residential properties in terms of materials used, installation process, and maintenance requirements. Investing in experienced professionals will ensure your business gets the best possible service and results.
