We repair sagging and accident damaged roof linings. The inner foam of the roof lining material has a lifespan of about 8-10 years. After that period it begins to rot and crumble. This is a natural and unavoidable process, its not about the heat as other people think. The best way to repair any damaged material is to completely replace the old material with a new material which comes with a new foam backing guaranteed to last for many years to come.
