Protecting Your Commercial Property: A Guide to Roofing Maintenance and Replacement for Property Managers

As a property manager, you are responsible for maintaining the overall condition of your commercial property, and one of the most critical components is the roofing system. A well-maintained roof protects the building’s interior from the elements, but an aging or damaged roof can lead to significant property damage, higher energy costs, and even pose a risk to tenants and visitors. Here is everything you need to know about roofing on your commercial properties to ensure their optimal condition.

Types of Commercial Roofs

Before you can address any roofing concerns, it’s essential to identify the type of roof you have on your commercial property. There are several types of commercial roofs, including:

  1. Built-Up Roofing (BUR): A traditional flat roofing system composed of alternating layers of tar and gravel or other materials.
  2. Modified Bitumen: Similar to BUR, but with an added layer of polymer-modified bitumen that offers additional strength and flexibility.
  3. TPO: A single-ply roofing system made of thermoplastic polyolefin, which is a durable and energy-efficient option.
  4. EPDM: A rubber roofing system that offers excellent durability and resistance to UV rays.
  5. Metal Roofing: A durable, long-lasting roofing option that offers excellent protection from the elements.

Common Roof Problems

No matter what type of roofing system you have on your property, it’s essential to be aware of common commercial roofing problems that could lead to costly repairs and potential safety hazards. Here are some of the most common roofing problems:

  • Leaks: Water leaks are a prevalent issue that can cause significant property damage and health hazards from mold and mildew growth.
  • Ponding Water: Water that pools on a flat or low-slope roof can lead to structural damage, roof membrane deterioration, and mold growth.
  • Roofing Material Damage: Wind, hail, and other weather events can cause significant damage to roofing materials, including missing shingles, punctured membranes, and bent or dented metal panels.
  • Poor Drainage: Poor drainage can cause water to accumulate on the roof, leading to water damage, mold growth, and roof deterioration.
  • Roofing System Age: All roofing systems have a finite lifespan, and as they age, they become more susceptible to damage and require more maintenance.

Roofing Maintenance

Regular roofing maintenance is the key to extending the life of your commercial roofing system and avoiding costly repairs. Here are some essential roofing maintenance tasks you should perform regularly:

  • Inspections: Regular commercial roof inspections can help identify potential roofing problems before they become major issues. You should inspect your roof twice a year, in the spring and fall, and after any significant weather events.
  • Cleaning: Regular cleaning can prevent debris from accumulating on the roof, which can lead to water pooling and potential damage. Clean the roof and gutters of leaves, branches, and other debris regularly.
  • Repairing Damage: If you notice any damage during a roof inspection or cleaning, address it promptly to prevent it from becoming a more significant problem.
  • Removing Snow and Ice: Snow and ice can accumulate on the roof and cause significant damage. Use a snow rake to remove snow and ice dams from the roof.
  • Addressing Drainage Issues: If you notice any drainage issues during an inspection, address them promptly to prevent water damage and potential mold growth.


Roof Replacement

Despite regular maintenance and repairs, all roofing systems will eventually need replacement. Here are some signs that it’s time to replace your commercial roofing system:

  1. Age: Most commercial roofing systems have a lifespan of 20-30 years. If your roof is approaching or exceeding that age, it’s likely time to consider replacement.
  2. Significant Damage: If your roof has significant damage, such as multiple leaks, extensive ponding water, or severe material damage, it may be more cost-effective to replace the entire roofing system rather than continuing to make repairs.
  3. Energy Efficiency: An aging roofing system can become less energy-efficient, leading to higher energy bills. A new, energy-efficient roofing system can save you money on energy costs over time.
  4. Building Codes: If your commercial property’s roofing system is not up to current building codes, it may be necessary to replace it to ensure compliance.

Choosing a Roofing Contractor

When it’s time to replace your roofing system, choosing the right contractor is crucial. Here are some tips to help you choose a qualified commercial roofing contractor:

  1. Check References: Ask for references from previous clients and follow up with them to see if they were satisfied with the work.
  2. Verify Insurance and Licenses: Make sure the contractor is fully licensed and insured to protect you from liability in case of accidents or damage.
  3. Get Multiple Bids: Get multiple bids from different contractors to compare pricing and ensure you’re getting a fair price for the work.
  4. Ask About Experience: Make sure the contractor has experience with the type of roofing system you have and has completed similar projects in the past.
  5. Get a Written Contract: Ensure that all details of the project are outlined in a written contract, including materials, labor costs, and a timeline for completion.


Maintaining a well-functioning roofing system is critical to protecting your commercial property from damage and ensuring the safety and comfort of your tenants and visitors. Regular inspections, maintenance, and prompt repairs can help extend the life of your roofing system and prevent costly roof repairs. When it’s time to replace your commercial roofing system, choosing a qualified contractor is essential to ensure the job is done right. By staying on top of your roofing system’s maintenance and addressing any problems promptly, you can keep your commercial property in top condition for years to come.
