"We became interested in your product when we saw a neighbour's house roof... the look, warranty, neighbourhood references and benefits of an Interlock roof, persuaded us to contact Interlock.
The installation of an aluminum black slate roof on our house and garage is just being completed today. We are very satisfied with the result. It looks magnificent, and our neighbours are already commenting on the beautiful appearance.
We look forward to many years of satisfaction, and a return on our investment when we eventually sell our home."
