Metal roofing continues to gain popularity in 2025 for its sleek look, longevity, and energy efficiency. But like any roofing material, it’s not without its challenges. If you’re considering a metal roof or already have one installed, it’s important to understand the most common issues that can arise—and how to prevent or fix them.
1. Oil Canning (Waviness in the Panels)
What it is: Oil canning is a visible waviness in flat areas of metal panels, giving the roof a distorted look.
Why it happens: It’s often caused by improper installation, metal expansion/contraction, or manufacturing imperfections.
Solution: Work with experienced installers who use high-quality panels and follow proper fastening techniques. Using thicker gauge metal and ribbed panels can also reduce oil canning.
2. Noise from Rain or Hail
What it is: Metal roofs can be louder than other materials during heavy rain or hailstorms.
Why it happens: Metal is naturally more resonant, especially when installed over open framing without a solid deck.
Solution: Add insulation, sound-deadening materials, or a solid plywood deck underneath the panels to muffle the sound.
3. Scratches, Scuffs, and Fading
What it is: Over time, metal roofs may get scratched or faded from debris, foot traffic, or UV exposure.
Why it happens: Lower-quality coatings or improper maintenance can leave the roof vulnerable to damage.
Solution: Choose high-quality, factory-coated metal panels with UV protection. Avoid walking on the roof unless necessary, and regularly clean off debris.
4. Corrosion or Rust Spots
What it is: While many metal roofs are corrosion-resistant, improper installation or exposure to harsh elements can lead to rust.
Why it happens: If protective coatings are damaged or if incompatible metals are used together, corrosion can occur.
Solution: Select rust-resistant materials like aluminum or galvanized steel. Ensure fasteners and flashing are compatible and inspect regularly for scratches or coating damage.
5. Expansion and Contraction Issues
What it is: Metal expands in heat and contracts in cold, which can lead to fasteners loosening or panels buckling.
Why it happens: Improper installation or using the wrong fasteners can make the problem worse.
Solution: Use slotted holes and flexible fasteners designed to allow movement. Regular maintenance can catch loose fasteners early.
6. Leaks Around Flashings and Fasteners
What it is: Leaks are rare in properly installed metal roofs but can occur at penetrations, seams, and fasteners.
Why it happens: Fasteners may loosen over time or flashing can degrade, especially around chimneys, vents, and skylights.
Solution: Routine inspections and maintenance are key. Check flashings and sealants annually and replace damaged components promptly.
7. Installation Errors
What it is: Poor installation is one of the leading causes of premature roofing problems.
Why it happens: Inexperienced contractors or rushed jobs can result in misaligned panels, overdriven screws, or improper sealing.
Solution: Hire a professional roofing contractor with proven experience in metal roof installations. Always check reviews and request references.
