The majority of clay roof tile manufacturers guarantee their products for 30 years, but it is common knowledge within the industry that the life span of a clay roof tile is closer to 100 years. Improvements in quality control in the manufacturing process can only be effective if proper maintenance is carried out. To ensure this, manufacturers provide guidance on what to look for. An inspection check list highlights the areas that should be monitored:

• Missing, damaged or chipped tiles
• Deterioration, creep or cracking of metal-lined valleys
• Loose, broken or missing ridges and hip tiles
• Metal flashings and pointing
• Eaves, gutters and guttering joints clear of debris

Members of the Clay Roof Tile Council adhere to stringent standards which include:
