Ensure your roof structure is in good condition
Onduline products are designed for waterproofing and are not structural components. The structure in which Onduline products are installed will have a direct effect on the products performance. For example, if the roof rafters / purlins / battens / deck / frame distort / bend / weaken with time they will force Onduline products to distort which could lead to a product failure unrelated to the actual Onduline product. If unsure of your roof structure condition you must seek advice from a professional roofer or structural engineer.
