Metal Roof Leak Causes and Solutions

Metal roofs are known for their durability, energy efficiency, and longevity, often lasting 40 to 70 years when properly maintained. However, metal roofs are not immune to damage. Metal roof leaks typically arise from aging materials, poor installation, or environmental exposure. Below are common causes metal roofs may leak and their solutions:

1. Improper Fastener Installation

Cause: Overdriven, underdriven, or misaligned screws allow water to seep through.
Solution: Inspect and replace fasteners with the correct torque. Use neoprene washers for sealing.

2. Failed Seams or Laps

Cause: Expansion and contraction from temperature changes loosen panel seams over time.
Solution: Apply seam sealant or install standing seam clamps. Regular resealing is key.

3. Missing or Damaged Sealant

Cause: UV exposure or age breaks down sealant around joints and penetrations.
Solution: Remove deteriorated sealant and apply high-performance, UV-resistant roof sealant.

4. Rust and Corrosion

Cause: Prolonged exposure to moisture leads to metal oxidation.
Solution: Remove rust with wire brushing and treat with corrosion-resistant coating or replace sections.

5. Clogged or Damaged Gutters

Cause: Water overflows and penetrates roof edges when drainage is restricted.
Solution: Clear debris and install guards. Re-angle gutters to ensure proper water flow.

6. Improper Flashing

Cause: Incorrect or failed flashing around chimneys, vents, and edges causes entry points for water.
Solution: Replace faulty flashing with correctly sized, watertight alternatives.

7. Roof Penetrations (Vents, HVAC, Skylights)

Cause: Water seeps in where the roof is punctured for utilities or structures.
Solution: Reseal or reflash penetrations using compatible materials and secure closures.

8. Punctures or Impact Damage

Cause: Hail, falling branches, foot traffic dents, or punctures in panels.
Solution: Patch minor holes with metal-compatible sealant or replace panels in severe cases.

Tip: With the right approach, including a professional maintenance plan, costly repairs can be avoided and roof performance maximized.
