Are you suffering from a leaking metal roof? Learn how to distinguish between leaks caused by nail holes and those caused by corrugation overflow to find the most accurate, cost-effective, and durable repair solution.
Corrugated metal roofing is a staple in modern construction. However, leaks are an inevitable challenge. To fix them permanently, you must distinguish between leaks caused by screw holes and leaks caused by corrugation overflow.
Causes: UV degradation of rubber washers, mechanical vibration from wind, or improper installation.
Signs: Water dripping directly under the purlins and visible rust around the screws.
Causes: Low roof pitch (less than 10%), insufficient overlapping between sheets, or extreme rainfall exceeding the drainage capacity.
Signs: Leaks occurring along the seams during heavy storms or high winds.
