I have used Cotec twice now over the past 6 years and cannot recommend them highly enough. They undertake the work to a very high standard and the clean up operation was exceptional. Sam even came back at a later date with a replacement tile that he had discovered to repair a slightly cracked one in my roof. There are a number of companies advertising similar services but I would be surprised if anyone can match this standard. All work completed as per the Statement of Work, on time and at the agreed price. I will certainly be using them again in two years time when the roof needs cleaning.
