Common Commercial Roofing Problems and How to Avoid them

The roof of your commercial building is one of the most important parts of the structure. It protects your business, employees, and assets from the outside elements. However, like any other roofing system, commercial roofs are susceptible to various issues that can lead to significant damages and costly repairs. In this blog post, we will discuss ten of the most common commercial roofing problems and provide expert advice on how to prevent them. Whether you own a warehouse, an office building, or a retail store in Charleston, SC, this information is invaluable in ensuring the longevity and safety of your commercial roofing system.

Roof Leaks

One of the most common and troublesome roofing problems that commercial property owners often encounter with their roofs is the problem of leaks. A roof leak not only threatens the overall integrity of your property’s structure but can also pave the way for the insidious growth of mold and mildew, which can further exacerbate the damage and jeopardize the health and safety of the occupants. To avoid leaks, inspect your roof regularly for signs of damage, such as cracks or holes. Repair any damage promptly to prevent leaks from occurring. Additionally, make sure your roof is properly insulated and ventilated, as these two things can affect your roof’s lifespan.

Poor Drainage

Proper drainage is paramount for your roofing system as it prevents water damage. Improper installation or blockage of your roof’s drainage, caused by debris or other obstructions, can result in water accumulation on the surface. This accumulation can give rise to a range of issues, including leaks, deterioration of roofing materials, and potential structural damage. It is imperative to ensure that your roof’s drainage system is well-designed, regularly maintained, and free from any blockages to safeguard your building from the detrimental effects of water infiltration. To avoid potential drainage issues, it is crucial to regularly clean your gutters and ensure that no debris or obstructions hinder the smooth flow of water. By taking these preventive measures, you can effectively safeguard your roof and prevent any potential water damage that may arise from clogged gutters.

Ponding Water

Ponding water occurs when water pools on your commercial roof and doesn’t drain off properly, resulting in various issues, including leaks, mold growth, and even structural damage to your building.

To avoid this issue, make sure your roofing system is designed with proper drainage and slope. Remove any debris, such as leaves or branches, from your roof to prevent water pooling. Lastly, inspect your roof regularly for any signs of water damage or ponding and fix them immediately.

Weather Damage

The impact of harsh weather conditions can significantly reduce the lifespan of your commercial roofing system over time. To safeguard your building from long-term weather damage, make sure to apply a protective coating that is designed to withstand extreme temperatures, UV rays, and other environmental factors. A quality protective coating provides a protective layer that shields your roof from inclement weather, thus preventing any damage or deterioration of the material over time. Additionally, such coatings can help reduce energy costs by increasing insulation and reflecting heat away from the building. Investing in a quality protective coating ensures that your roof is well-protected from the elements and remains in pristine condition for years to come.

Thermal Shock Damage

Thermal shock damage occurs when drastic temperature fluctuations cause roofing materials such as asphalt tiles or metal panels to expand and contract. This expansion and contraction can lead to cracks, blisters, and other damage that can weaken the structure of your roof. To avoid thermal shock damage to your commercial roofing system, inspect it regularly for any signs of distress. Additionally, apply a protective coating or insulation to help regulate temperatures on your roof and reduce the occurrence of thermal shock damage.

Poor Installation

When it comes to commercial roofing systems, a proper installation process is essential in ensuring the longevity and durability of your roof. A poorly installed roof can result in various problems, such as leaks, premature deterioration, and even structural damage to your building.To prevent any issues arising from improper installation, you must choose an experienced contractor for the job. An experienced professional will have the skills and knowledge required to ensure that your roof is installed correctly and complies with industry standards.

Wind Damage

Charleston is susceptible to high winds , which can damage your commercial roof. High winds can cause tiles to lift or even blow off entirely, leaving your roof vulnerable to leaks. To mitigate wind damage effectively, it is important to guarantee the proper installation of your roofing system and the secure fastening of all tiles in place. This critical measure ensures the longevity and durability of your roof, shielding your property from potential harm caused by strong winds.

Hail Damage

Hail storms are another common risk in Charleston, SC. However, with the right roofing system and protective coating in place, you can effectively protect your commercial property from any hail-related damage. Investing in a quality hail-resistant roofing system is key to avoiding expensive repairs that come with hail damage. Additionally, applying a protective coating helps prevent water infiltration and can provide additional protection from the elements.


Punctures on your commercial roof can happen for several reasons, such as fallen tree branches, hailstorms, or foot traffic. To prevent punctures or roof leaks, ensure workers walking on the roof wear soft-soled shoes and avoid placing heavy equipment on the roof.

Lack of Maintenance

Lack of maintenance is one of the most prominent reasons why commercial roofs fail. Regular maintenance can help prevent leaks, improve drainage, and increase the lifespan of your roofing system. Schedule regular inspections and maintenance with a professional roofing contractor to ensure your roof stays in good condition.

UV Damage

The sun’s ultraviolet (UV) rays can cause significant damage to your roof over time. UV damage may result in cracking, warping, or even complete roof failure. To effectively mitigate UV damage, it is highly recommended to consider implementing a reflective roof surface that possesses the capability to efficiently deflect harmful UV rays. This proactive approach not only safeguards the structural integrity of your property but also contributes to energy efficiency and long-term cost savings.


Shrinkage is a common issue that often arises in flat roofing systems. When your roof material contracts, it can potentially lead to the development of cracks and splitting, which in turn may result in leaks and other related problems. To avoid shrinkage, your roofing system should be properly designed and installed to allow for sufficient expansion and contraction with temperature changes. Additionally, it is important to maintain the roof regularly to detect any issues that may arise from improper installation or a lack of maintenance. By ensuring that all of these preventive measures are in place, commercial property owners can significantly reduce the risk of roofing problems and enhance the overall longevity and performance of their commercial roofs.

If your roof is old and showing signs of wear and tear, it’s time to consider a replacement to avoid costly repairs and potential damage to your property. Consult a professional roofing contractor to determine if a replacement is necessary. It is also important to note that regular maintenance and upkeep can help extend the life of your commercial roof. Schedule annual inspections with a professional contractor to identify potential problems and take corrective action before they become major issues.
