My career in roofing began in 1978, predominately on new build developments. In 1987, although continuing with the new builds, I began to branch out into domestic roofing. This included re-roofs, extensions, repairs and leak investigation. Alongside this, in 2010 I took a Contracts Manager position with a national roofing company, In this role I am responsible for the labour and materials required for various developments in the South East. It is also part of my role to oversee the customer service team. My contacts within the industry enable me to obtain very competitive prices on materials. I also have a large labour resource to carry out even the bigger jobs.

There isn’t enough space on here to describe how happy I am and stress free Rob and his team made the process. I had a major extension to the rear and side of the home which meant I wasn't able to use the bottom area of my home at all. Rob and his team took care of everything and also provided so much extra help all the time any time and keeping up with the consistent service is truly unmatchable. I’m very happy with the work, the finishing and everything else. Choose Rob and his team and you can’t go wrong
