Oil Canning **Oil canning** is visible waviness or stress wrinkling in the flat areas of metal panels. Causes include: - **Over-production:** Extreme pressure during the metal coiling process. - **Thermal expansion:** Insufficient space for panels to expand and contract. - **Improper handling:** Mishandling and poor storage by contractors. **Prevention:** Use thicker metal, opt for a rib roller profile, and hire experienced installers. --- ### 2. Leaking Leaks can occur due to: - **Failed fasteners:** Screws or nails that have come loose. - **Failed seams:** Joints between panels not sealed properly. - **Failed flashing:** Metal strips meant to direct water away from seams and joints. **Tip:** Regular inspections and maintenance can help catch these problems before they cause significant damage. --- ### 3. Scuffing & Scratching Scuffing and scratching can happen during improper handling or installation, stripping the protective coating and leading to rust and corrosion. **Solution:** Use touch-up pens for minor damage. Replace panels for deeper scratches. --- ### 4. Corrosion While generally resistant, metal roofs can still corrode: - **Underside corrosion:** If the underside isn’t properly coated. - **Saltwater corrosion:** Common in coastal areas. - **Cut edges:** Exposed edges can rust over time. **Prevention:** Use protective coatings and metals like aluminum or zinc in coastal areas. --- ### 5. Dissimilar Metals & Materials Combining different metals can lead to galvanic corrosion. Examples: - Steel and copper - Aluminum and copper - Galvanized steel and lead **Tip:** Use compatible materials or physical barriers to separate different metals. --- ### 6. Chalking & Fading UV exposure can cause paint to break down, leading to chalking (white residue) and fading (color change). This affects both appearance and heat reflection. **Solution:** Use high-quality paint with UV resistance and check for paint warranties. --- ### 7. Installation Errors Common errors include: - **Missing parts** - **Loose screws** - **Poorly attached flashing** **Tip:** Always hire an experienced contractor to ensure proper installation.
