The answer to 'metal roof curling' is that metal roofing can sometimes curl or buckle due to improper installation, thermal expansion and contraction, or manufacturing defects. Symptoms include wavy or uneven roof panels, gaps between panels, and potential leaks. To fix curling, solutions may include re-securing the panels, replacing damaged sections, or adjusting the roof's structure to accommodate expansion and contraction. If the curling is widespread or the roof is older, it's best to consult a professional roofing contractor to assess the issue and recommend the best course of action.
Metal roofing is generally very durable, but improper installation or underlying structural issues can lead to curling over time. Homeowners should regularly inspect their metal roof and address any curling or other problems promptly to prevent further damage.
