Common Causes of Metal Roof Leaks


Before you can effectively repair a roof leak in a metal roof, it’s crucial to identify the root cause of the issue. Here are some common causes of metal roof leaks:

  • Poor Installation: Improper installation is one of the leading causes of metal roof leaks. If the panels, fasteners, or seams were not correctly installed, water can infiltrate your roof.
  • Aging and Wear: Over time, even well-installed metal roofs can develop wear and tear. Weather exposure, expansion, and contraction due to temperature changes can lead to cracks, holes, or rust.
  • Damaged Fasteners: Metal roofs rely on fasteners to hold the panels in place. If these fasteners become loose, damaged, or corroded, they can create entry points for water.
  • Seam Problems: Metal roofs consist of panels that are joined together by seams. If these seams were not properly sealed during installation or have deteriorated over time, they can allow water to seep through.
  • Debris Accumulation: Leaves, branches, and other debris can accumulate on your metal roof, causing water to pool in certain areas. Over time, this can lead to leaks.
  • Corrosion: Rust or corrosion can develop on metal roofs, compromising their integrity and making them susceptible to leaks.
  • Penetrations: Roof penetrations, such as vents, chimneys, and skylights, can be potential leak sources if their flashing or seals deteriorate.

5 Repair Solutions for Metal Roof Leaks

Once you’ve identified the cause of your metal roof leak, it’s time to consider the appropriate repair solution. The following are some common repair methods for metal roof leaks:

1) Sealants and Caulk

For small, localized leaks, sealants and caulk can be effective temporary solutions. Clean the affected area thoroughly, remove any rust or debris, and apply a high-quality roofing sealant or caulk to seal the leak. Make sure to choose a product compatible with your metal roof material (e.g., silicone sealant for silicone-coated metal).

Keep in mind that this is a temporary fix and should be followed up with more comprehensive repairs.

2) Patching

For larger holes or damaged sections of your metal roof, consider using patches made of compatible roofing materials. Clean the area, apply an adhesive or sealant, and then adhere the patch over the damaged section, ensuring a watertight seal.

This method is best suited for isolated areas of damage and may not be a long-term solution for extensive roof issues.

3) Replacing Damaged Panels


If the damage is extensive and affects multiple panels, it may be necessary to replace the damaged sections altogether. Remove the damaged panels, purchase replacement panels that match your existing roof, and install them correctly, ensuring proper alignment and sealing. This solution is more labor-intensive and may require professional assistance for precise matching and installation.

4) Flashing Repair or Replacement

Leaks around roof penetrations often stem from damaged or deteriorated flashing. Remove the old flashing and replace it with new, properly sealed flashing. Ensure that flashing is securely anchored and sealed to prevent future leaks.

5) Roof Coatings

Roof coatings, such as elastomeric or reflective coatings, can provide an added layer of protection to your metal roof. These coatings can help seal small cracks, protect against corrosion, and improve the overall durability of your roof. Follow the manufacturer’s instructions for application, and be sure to clean and prepare the roof surface beforehand.

When to Call a Roofing Contractor

Metal roofs have many pros and cons, one of them being that they require specialists to install and maintain. While homeowners with moderate DIY skills can handle some metal roof leak repairs, there are situations where it’s best to enlist the expertise of a professional roofing contractor:

  • 🏚️ Extensive Damage: If your metal roof has sustained extensive damage or if the leak affects a large area, it’s advisable to consult a roofing contractor. They have the experience and equipment to assess the extent of the damage and recommend appropriate repairs or replacement.
  • 🦺 Safety Concerns: Roof work can be dangerous, especially for those without proper training and safety equipment. If you’re uncomfortable with heights or lack experience working on roofs, it’s safer to leave the job to professionals.
  • 🤔 Warranty Considerations: If your metal roof is still under warranty, attempting DIY repairs may void the warranty. Hiring a professional ensures that any work performed is in compliance with the manufacturer’s guidelines.
  • 😵‍💫 Complex Roof Systems: Some metal roofs are designed with intricate systems, such as standing seam profiles or specialized coatings. Repairing these roofs requires specific knowledge and tools that professionals possess.
  • 🕰️ Time Constraints: Roof leak repairs can be time-consuming, especially if you need to identify the source of the leak or acquire specialized materials. Contractors can often complete repairs more quickly and efficiently.
