Causes of Metal Roof Tile Damage

Metal roof tiles are widely used to replace traditional tiles due to their advantages. However, metal roof tiles can still become damaged over time. It's important to understand the causes of metal roof tile damage.
1. The Material Has Reached Its Maximum Age
Generally, metal roof tiles have a lifespan of 20 to 30 years, depending on the type and thickness. If the roof tiles are older than that, damage will more easily appear, even if they previously appeared to be in good condition.
2. Repeated Exposure to Extreme Weather
Areas with high rainfall, extreme temperatures, or strong winds are more likely to accelerate damage to metal roof tiles. If the tiles lack an adequate protective coating, their lifespan will be significantly shortened.
3. Unprofessional Installation
Metal roof tile installation requires attention to the roof slope, screw placement, and joints between sheets. Small errors during installation can create gaps for water ingress, which will become a major problem in the long run.
4. Substandard Material Quality
Cheap metal roof tiles with a thin coating or no anti-rust coating will quickly deteriorate. The thickness of the material (measured in millimeters or zinc coating, for example) significantly determines its durability.
5. Lack of Regular Maintenance
Metal roof tiles require regular cleaning of dirt, moss, and dry leaves. Without maintenance, the protective layer can erode, accelerating corrosion.
Delaying the replacement of worn roof tiles will only increase repair costs and the risk of damage to the interior of your home. By understanding the causes of metal roof damage, you can plan your roof replacement appropriately and efficiently.
