Tiles would normally last for 30 years and beyond. As the roof ages, the protective coating wears off due to wear and tear. When this happens, the quality of the roof tile deteriorates and the roof tile becomes brittle if left untreated. The roof tile will then be prone to cracks resulting in roof leakages. Thus it would be prudent to carry out Restoration Works to old roof before this happens to avoid costly re-roofing costs.
