I have a 40+ concrete tiled roof, badly in need of repair. They pressure cleaned the roof, re-grouted and fixed broken or damaged tiles. They gave the roof a generous coating of sealant and a couple of coats of Newtech protection (large choice of colours). They cleaned away all dirt and rubbish involved in the process at the end of each day and only took a day and a half to have the job completed. They were courteous, professional and friendly. They kept me informed at every stage of the process. The price was more that competitive and fare. I now have an amazing roof that will last for years. Could not recommend these guys enough.
