Common Metal Roof Repairs – Discover the most frequent issues with metal roofs and how Shepherd Metal Roofing repairs and restores roofing systems across Dallas–Fort Worth and East Texas.
Why Metal Roofs Still Need Occasional Repairs
Metal roofing is known for its durability, longevity, and low maintenance, especially in demanding climates like Dallas–Fort Worth and East Texas. But even the strongest metal roof isn’t completely immune to wear and tear over time.
At Shepherd Metal Roofing, we specialize in both installations and expert repairs. From minor leaks to storm damage, our team is ready to help you extend the life of your metal roof with fast, reliable service.
Whether you have a standing seam, R-panel, or another type of metal system, here are the most common metal roof issues to watch for — and how we fix them.
1. Loose or Damaged Fasteners
🔧 What Happens:
Metal roofs often use screws or clips to attach panels to the decking. Over time, thermal expansion (heating and cooling) can cause these fasteners to loosen or back out. On exposed-fastener systems like R-panel, this is especially common.
🛠️ Our Fix:
We inspect and replace loose or missing screws with oversized or upgraded fasteners, and install new sealing washers to maintain a watertight seal. For standing seam roofs, we check clips and make sure panel movement is allowed without stressing the seams.
2. Sealant Deterioration
🔧 What Happens:
Sealants used around penetrations (vents, chimneys, skylights) can break down from UV exposure and weathering. This leads to minor leaks that worsen over time.
🛠️ Our Fix:
We remove old sealant and apply commercial-grade urethane or silicone roofing sealants that offer flexibility and adhesion even in extreme Texas heat.
3. Panel Dents or Damage from Hail or Debris
🔧 What Happens:
Though metal roofs are hail-resistant, strong storms (especially in North Texas) can cause cosmetic or structural dents. Falling limbs or windblown debris can also deform panels or flashings.
🛠️ Our Fix:
Depending on severity, we either replace the damaged panel, restore shape, or reinforce the affected section with matching materials. Our goal is to retain both performance and appearance — especially in high-visibility areas.

4. Leaky Flashing or Seams
🔧 What Happens:
Improperly installed or aged flashing can allow water to penetrate near walls, chimneys, or dormers. Standing seam roofs may also leak if seams are not properly locked or have developed uplift from wind.
🛠️ Our Fix:
We perform a detailed inspection of all flashing areas and replace or reinforce with custom-bent flashing pieces. For standing seam roofs, we reseam or seal vertical joints using manufacturer-approved materials.
5. Corrosion or Rust (on Uncoated Panels)
🔧 What Happens:
While most modern metal roofs are coated with protective finishes like Kynar 500®, older metal roofs or low-grade installations may develop rust or corrosion, especially around cut edges, fasteners, and ponding water zones.
🛠️ Our Fix:
We treat rusted areas by cleaning, priming, and recoating with color-matched paint or roof coating systems. For severe cases, panel replacement may be recommended to restore integrity.
6. Improper Roof Penetrations
🔧 What Happens:
Satellite dishes, HVAC lines, and plumbing vents often get added to the roof after installation. If improperly flashed or sealed, these penetrations can create weak points for water intrusion.
🛠️ Our Fix:
We remove, reseal, or install custom boots around penetrations. We also consult with property owners about relocating or minimizing future penetrations for a cleaner, longer-lasting system.
Don’t Let Small Issues Become Big Problems
If you spot any of these signs:
- Dripping or ceiling stains
- Rust spots on the roof
- Missing screws or clips
- Warping around seams or flashings
- Pooling water near vents or valleys
…it’s time to schedule a professional inspection.
