Common Causes of Flat Roof Leaks
Flat roofs are a popular choice for commercial buildings due to their affordability, accessibility, and ability to accommodate HVAC units and solar panels. However, their low-slope design makes water drainage more challenging compared to pitched roofs. Without adequate slope or drainage, water tends to accumulate on the surface, increasing the risk of leaks and structural issues over time.
Here are some of the most common reasons flat roofs develop leaks:
- Ponding Water: Prolonged standing water from poor drainage or blocked scuppers can wear down roofing seams and accelerate membrane deterioration.
- Punctures or Tears: Routine foot traffic, wind-blown debris, or impacts from tools and equipment can damage the membrane, creating vulnerabilities for water to enter.
- Cracked Flashing or Seams: Flashing and seams around rooftop penetrations—like vents, drains, and HVAC units—are prime leak zones. When seals fail due to age or movement, water intrusion can follow.
- Blistering or Bubbling: Moisture trapped beneath the membrane or within insulation can expand in heat, causing blisters. These weak spots can rupture, exposing the roof to more damage.
- Aging Materials: Most commercial flat roofs have a lifespan of 15–25 years, depending on the material. As the system ages, its flexibility, adhesion, and waterproofing capabilities decline, making leaks more likely.
Detecting these problems early and addressing them with professional repairs can significantly prolong your roof’s service life and help you avoid costly interior damage or premature replacement.
Flat Roof Leak Repair Process

At Shark Commercial Roofing Systems, we take a systematic and results-driven approach to flat roof leak repair in Riverside, CA. Our process is designed to not only stop active leaks but also improve the overall resilience of your commercial roofing system.
Leak Detection and Inspection
We begin with a thorough roof evaluation using advanced tools such as infrared moisture scanners and core sampling (if needed) to locate the exact source of the leak. This step helps us identify both visible damage and hidden moisture that could compromise your building’s structure.
Surface Cleaning and Preparation
To ensure that our repairs last, we clean the roof surface thoroughly. This includes removing standing water, debris, algae, and any loose or deteriorated materials around the damaged area. Proper surface prep ensures optimal adhesion and bonding of new materials.
Targeted Repair Solutions
Based on the roofing type, TPO, EPDM, PVC, or modified bitumen, we use system-specific repair techniques. This may involve heat-welding seams, applying membrane patches, reinforcing flashing, sealing penetrations, or replacing affected insulation. Our team focuses on precision and compatibility to prevent future leaks.
Quality Assurance Check
Once repairs are complete, we conduct a final walkthrough and water-tightness test to ensure the leak is fully resolved. We also provide documentation and, if appropriate, maintenance recommendations to help you avoid future problems.
Every commercial roof has unique challenges, which is why we tailor our repair plans to suit your building’s needs, roofing system, and long-term performance goals. With Shark Commercial Roofing Systems, you get repairs that last, backed by local expertise and a commitment to excellence.
