We wouldn't be anything without our clients. Well, that and our exceptionally well crafted estimates. As such our main focus is on customer service. Here are some of their kind words...
After being introduced to 1Roof by an architect friend a few years ago, we haven’t looked back. Not only are Leo and the team attentive, precise and diligent they also offer a level of flexibility that I have yet to come across in any other estimating service. I wouldn’t hesitate to recommend them to anyone. Builder, architect, client or otherwise.

I have been using 1Roof for a number of years now. Having tried many other Quantity Surveying services, I can honestly say they are the best we have come across. Nothing is ever too much trouble and Leo and the team have never missed a deadline. I also like to make a number of edits to the tenders which I am sure drives Leo up the wall sometimes but nothing is ever too much trouble. Leo and the 1Roof team are always available and happy to talk things through to get things where we need them to be. I can highly recommend 1Roof to anyone out there looking for a reliable and professional Quantity Surveying service.

Leo and the whole team at 1Roof are extremely helpful and diligent in their evaluations. This service has given my company an air of higher professionalism and efficiency I simply don't have the time to provide. For a small portion of contract funds 1Roof has freed my time up to concentrate on actual project management, while guaranteeing a firm cost evaluation that I am comfortable with for any particular project. I couldn't recommend everyone and the service enough!

It’s a tough and very competitive building industry at the moment. You need 1Roof on your side! Getting the pricing correct is the single most important factor in the success of a construction business. We know we cannot write our own ticket in a super competitive market but on the other side of the ledger if we sign a loss-making contract it obviously can ruin a business and the consequences for a client are pretty grim. We have absolute confidence that 1Roof can get it spot on. Their software and systems are constantly adjusted to the current materials and rates which are miles ahead of anything we can keep on top of. Leo and the team are super responsive, always on the end of the phone or email.
