This depends somewhat on your choice of colours and paint coatings. Our PVDF painted metal will resist colour fading, as well as chipping, cracking, and premature ageing and has a recommended finish warranty of 40 years. SMP painted metal is also an excellent choice, and is usually warrantied for 40 years, but will not be as impervious to wear as the PVDF colours. Regardless of colour choice, your Metal Lab roof will look brand new for decades after installation!
