​How are CLS Roofing different to other roofing services?

​

First and foremost, CLS Roofing are  strictly a roofing company. Fully qualified, fully insured and fully compliant to carry out your roof repairs. It is advised to stay away from building companies and hybrid roofing companies that have additional services after their trading name, such as, "building", "maintenance", "brickwork" and "driveways". Builders and hybrid companies are responsible for up to 70% of call backs within 10 years of original roof installations, this is because they are neither qualified nor competent to be on your roof. These are known as "Chancers" or a more familiar phrase, "jack-of-all-trades" and are responsible for extremely costly and avoidable mistakes.
CLS Roofing are qualified, insured and time served to work on your roof with all documents and certification up to date.
