About me

I have been a part of Garland UK since 2013 and work across Reading, Portsmouth, Guildford and the surrounding areas.

When working with my clients, I think it is important to come from a place of complete transparency, providing as much technical and relevant information on their asset to help make an informed decision that’s right for them. I love being able to facilitate this process, helping with difficult roof detailing, or even customised tapered schemes that guarantee effective roof drainage. This allows us to protect the building envelope for years to come.

With the brilliant support from my Technical Assistant, Tony Upfold, we are able to take a failing roof and transform it into an effective, efficient and fully functional asset, that will last the length of the guarantee, as a minimum!

Being an employee-owner means that I am part owner of our company, and I have a vested interest in every project being installed to the highest of standards. This enables our roofs to out-last the length of the guarantee period. We always put the customer first, Garland second and ourselves third.
