The Most Common Commercial Roof Problems in Oklahoma and How to Fix Them

Commercial roofs in Oklahoma face unique challenges due to the state’s unpredictable and often extreme weather patterns. From blazing heat and gusty winds to sudden hailstorms and tornadoes, the conditions here can take a toll on any roof—especially those covering large commercial spaces. Statewide Roofing is committed to helping business owners recognize and address these common issues before they lead to expensive repairs or replacements. Here, we explore the most frequent commercial roof problems in Oklahoma and offer solutions to keep your roof in top shape year-round.

1. Leaks and Moisture Accumulation

One of the most pervasive issues with commercial roofs, leaks, and moisture accumulation, often result from Oklahoma’s heavy rain and severe storms. Even a small leak can lead to extensive water damage, affecting insulation, structural integrity, and indoor air quality due to mold growth. Leaks are especially common in buildings with older flat roofing systems.

Solution 

Regular inspections are crucial to addressing leaks. Look for areas with pooling water, especially around seams, HVAC units, or drainage points. Waterproofing and applying high-quality sealants can help reduce moisture infiltration. Additionally, ensure that roof drainage systems are clear to avoid pooling, which can escalate minor leaks into major issues. If leaks are recurring, a professional inspection from Statewide Roofing will assess if a larger repair or even a partial roof replacement might be necessary. If you have leaks that appear to be older or consistently have issues, get an inspection as soon as possible to ensure the leaks are not causing further damage

2. Blow-Offs and Wind Damage

Oklahoma’s notorious winds, particularly during tornado season, can wreak havoc on commercial roofs. High winds may lift roofing materials, loosen flashings, or tear sections of flat roof membranes, exposing the building’s interior to moisture and debris.

Solution

Regularly inspect the roof after windstorms to identify and secure loose roofing materials. Stronger wind-resistant roofing materials, such as reinforced membranes and standing seam metal roofs, can be a worthwhile investment in areas prone to high winds. Proper installation by experienced professionals, such as those at Statewide Roofing, can further enhance wind resistance. A maintenance plan with frequent inspections can detect and repair small issues before wind damage becomes severe.

3. Ponding Water

On flat commercial roofs, ponding water is a common problem. When rain accumulates without adequate drainage, it can create standing pools of water, leading to stress on roofing materials, structural weakening, and, over time, potential leaks and interior damage.

H3: Solution

Ensure that drainage systems are clear, effective, and strategically placed to direct water off the roof promptly. Installing a slight slope or tapered insulation can help encourage water flow. A roofing professional can also install drains, scuppers, or overflow pipes to improve drainage. Regular maintenance to clear debris and improve water flow is essential to prevent water from ponding on flat roofs.

4. Punctures and Tears in the Membrane

Hail storms and foot traffic from HVAC technicians or maintenance staff can lead to punctures, tears, or blisters in the roofing membrane. These vulnerabilities allow water to seep into the roof’s structure, resulting in leaks or, worse, structural damage.

Solution

Schedule regular inspections, particularly after a hailstorm, to identify and repair any membrane damage promptly. Using walkway pads in high-traffic areas and limiting roof access to necessary personnel can reduce wear. For repairs, a professional should apply high-quality sealants or membrane patches to ensure water-tight protection and prolong the life of the roof.

5. UV Damage and Thermal Shock

The sun’s powerful UV rays, combined with Oklahoma’s fluctuating temperatures, can cause a phenomenon called thermal shock. Roofs expand under heat and contract when temperatures drop, which can lead to cracks, splitting, or overall degradation of the roofing material.

Solution

Consider installing a reflective coating to reduce UV exposure and moderate temperature fluctuations. Reflective or “cool roof” coatings can significantly lower temperatures on the roof’s surface, reducing expansion and contraction. For roofs already showing signs of damage, having a professional re-coat your roof with UV-resistant materials or a membrane overlay can restore protection and add longevity.

6. Improper Installation

Improper installation remains a common issue affecting commercial roofs, often leading to premature wear, poor performance, and a higher risk of damage from wind, water, and sun. Some roofing materials, like TPO or standing seam metal, require specific installation techniques, and any deviation can compromise the roof’s lifespan.

Solution

When installing or replacing a roof, work with a reputable contractor like Statewide Roofing to ensure proper installation. Statewide Roofing professionals are trained in the latest techniques for all types of commercial roofing materials, from TPO to metal and beyond, ensuring that your roof is secure and built to withstand Oklahoma’s weather. If you suspect improper installation on an existing roof, a detailed inspection can uncover and address issues before they become costly problems.

7. Flashings and Edge Details

Flashings are a critical component of any roof, designed to prevent water from seeping into seams and joints. In commercial roofing, flashings around edges, vents, or HVAC units are particularly vulnerable to wear, cracking, and loosening, which can lead to leaks and water damage.

Solution

Inspect flashings periodically, especially after severe weather events. Have flashings re-secured or replaced as needed, using high-quality, weather-resistant materials. Statewide Roofing can inspect and upgrade your flashings to ensure water-tight integrity around all roof joints and penetrations.

8. Shrinkage

Certain roofing materials, such as EPDM (rubber) membranes, may shrink over time. Shrinkage can pull flashings, seams, and joints out of alignment, leading to gaps and potential leaks. Oklahoma’s temperature variations contribute to the expansion and contraction of materials, accelerating this process. This is especially possible if your flat roof system is older or was not installed properly.

Solution

Inspect for signs of shrinkage along seams and edges. Reinforcing weak areas with a compatible membrane or switching to materials that are less susceptible to shrinkage, such as TPO or PVC, can be beneficial. Proper installation and regular inspections by a trained professional can minimize shrinkage issues.

9. Clogged Drains and Gutters

Debris like leaves, dirt, and bird nests often clog drainage systems, especially in Oklahoma’s windy climate. Clogged drains and gutters prevent water from exiting the roof properly, leading to ponding, leaks, and even damage to the building’s exterior.

Solution

Schedule regular cleaning of drains and gutters, especially during the fall and after storms. Adding protective covers to gutters or screens to drains can reduce blockages. Statewide Roofing offers maintenance to help with cleaning and inspecting drainage systems to ensure your roof stays free of water-related issues.

10. Lack of Preventative Maintenance

Without regular preventative maintenance, small issues can escalate into costly repairs or replacements. A neglected roof may go years without an inspection, allowing damage to worsen over time.

Solution

Establish a maintenance plan with scheduled inspections at least twice a year, ideally in the spring and fall. This proactive approach can help you catch and repair small issues, saving you from significant repairs later. Statewide Roofing offers tailored maintenance programs to suit Oklahoma businesses, helping you extend the lifespan of your roof and reduce overall costs.
