Commercial Roof Care

The Essential Guide to Commercial Roof Maintenance

As the saying goes, “Out of sight, out of mind.” This could not be truer for commercial roofs. Being the highest point and outside the everyday line of sight, it is easy to overlook the importance of roof maintenance. However, neglecting the roof could lead to significant problems that may interfere with the operations of a business. Hence, commercial roof maintenance is a topic that every business owner and facility manager should be well-versed with.

The Importance of Commercial Roof Maintenance

A commercial building is a considerable investment, and the roof, which protects the whole structure, is a significant part of that investment. With proper maintenance, commercial roofs can last for decades, protecting the building from the elements while providing necessary insulation and contributing to overall energy efficiency.

Commercial roof maintenance helps in the early detection of potential issues such as leaks, corrosion, or structural damage, thereby preventing small problems from escalating into more serious, costly damage. Regular inspections and maintenance can also extend the life of your roof, reduce the need for replacement, and subsequently, save your business a significant amount of money in the long term.

Components of Commercial Roof Maintenance

Regular Inspections: The first step to maintaining your commercial roof is conducting regular inspections. It’s recommended to have your roof professionally inspected at least twice a year, usually in the spring and fall, or after severe weather events. These inspections should check for visible damage, debris, drainage issues, and signs of wear and tear.

Cleaning: Keeping your roof clean is crucial in maintaining its longevity. This includes clearing debris, such as leaves and branches, that could potentially cause blockages and water build-up. In some cases, roofs may also require a professional wash to prevent the growth of moss, algae, or fungi, which could lead to deterioration.

Repairs: After inspection and cleaning, the next step is to fix any identified issues. This could range from repairing small leaks to replacing damaged sections of the roof. Timely repairs prevent minor problems from becoming significant issues that may require a complete roof replacement.

Documentation: Keeping detailed records of all inspections, cleanings, and repairs is an integral part of roof maintenance. This documentation will help track the roof’s history and could be useful for warranty claims or in case of selling the property.

Types of Commercial Roofs and Their Specific Needs

Different types of commercial roofs require different maintenance approaches. Here’s a quick overview:

Flat Roofs: These are common in commercial buildings. They require regular cleaning to prevent debris and water build-up. Special attention should be given to the roof’s drainage system to ensure it’s functioning correctly.

Metal Roofs: These are known for their durability, but they can be prone to corrosion and rust. Regular inspections should look for signs of these issues so they can be addressed immediately.

Shingle Roofs: Popular for smaller businesses, shingle roofs can be damaged by harsh weather. Regular inspections should check for loose or missing shingles.

Preventative vs Reactive Maintenance

Adopting a preventative maintenance approach is more beneficial and cost-effective than a reactive one. A reactive approach only addresses problems after they’ve occurred, which could lead to higher repair costs and potential disruption to your business operations. On the other hand, preventative maintenance aims to identify and resolve issues before they escalate, preserving the integrity of the roof and saving money in the long run.


Maintaining your commercial roof is a crucial aspect of managing a commercial building. A well-maintained roof not only safeguards the people and property beneath it but also contributes to the overall efficiency and value of the building. Although it may seem like a daunting task, with a regular schedule of professional inspections, cleaning, and repairs, roof maintenance can be a breeze.
