Q: How long is a typical commercial roof expected to last?

A: The lifespan of a roof can be affected by several factors including the type and quality of the roofing material, the maintenance practices, the weather conditions, as well as the quality of the installation. Commercial roofs last on average between 10 and 40 years. Consult a professional roofer to determine the expected lifespan of your roof.

Q: Do I need to have a warranty on my commercial roof?
A: A warranty is highly recommended for your commercial roof. A warranty ensures that the roofing materials are covered, and the workmanship is covered for a certain period. It can protect you against unexpected repair costs if there are manufacturing defects or installation problems. There are different types of warranties, including warranties from the manufacturer and warranties for contractor workmanship. You should review the warranty conditions and discuss them with the roofing contractor in order to understand the coverage as well as any maintenance requirements.
Q: How often should commercial roofs be inspected?

A: Regular roof inspections will help identify any potential problems before they become major ones. A professional roofing contractor should inspect your commercial roof twice a year, once in the spring and again in the fall.

Inspections should also be performed after severe weather events, such as heavy snowfall or storms. Repairing any roofing problems as soon as they are identified can extend the life of the roof. This will also prevent costly damage.

Q: Can a commercial roofing system be repaired or must it be replaced?

A: The extent of damage, age of the roof and other factors will determine whether a commercial roofing system can be repaired. Minor issues like leaks or isolated damage can be repaired to extend the roof’s life. If the roof is damaged, has widespread deterioration or is nearing its expected lifespan, replacing it may be a more cost-effective solution. A professional roofing contractor will assess the condition of your rooftop and make recommendations based on its specific needs.

Q: What are the most popular types of commercial roofing material?
A: Several popular roofing materials are used in commercial applications. Some common options are:

  • Built-up roofing (BUR) is a multiple layer of asphalt and reinforcing fabrics.
  • Modified Bitumen is asphalt-based sheets that have been modified with polymers.
  • TPO (Thermoplastic Olefin), a single-ply roofing membrane composed of a mixture of rubber and plastic.
  • EPDM (Ethylene Propylene Diene Monomer): Synthetic rubber roofing membrane.
  • Metal roofing: Durable metal panels in steel, aluminum, or copper.
The choice of roofing materials is influenced by factors such as budgets, building requirements and climate. Consult a professional roofer to determine which material is best for your commercial roofing.
