Client Testimonials
“RPC Construction has had the pleasure of working with Graham Hill Roofing Ltd since 2005. Recently GH Roofing completed a new classroom at Rolleston Christian School for RPC Construction. Roofing on this project was completed ahead of programme and to a high standard without defects on the consultant’s remedial list.
We have always been impressed by the high quality workmanship achieved by GH Roofing on our projects. The procedures for health and safety documentation and pre‐planning prior to site always ensure the roofing component commences smoothly. Staff are always co‐operative, pleasant to deal with, and always find a way to solve problems which may arise on site during construction.”
“CPB Southbase JV recently delivered the Shirley Boys and Avonside Girls Project where GHR played an integral part in achieving completion of this flagship project as a first of its kind in NZ. It was great working with the team at GHR and their proactive approach to problem solving and working with the project team to deliver the best outcomes for the project. I enjoyed my experience working with the team at GHR on this project and look forward to the next opportunity where their services can be tendered.”
“We have engaged Graham Hill Roofing for over 10 years on a number of commercial roofing and cladding projects, we have been highly impressed with their expertise, effort and resources. They provide a one-stop solution for long-run metal and membrane systems with all access equipment provided for their own installations. Communication is always clear and concise and should any issues arise they are quickly resolved. I would have no hesitation in recommending the highly experienced team at Graham Hill Roofing to tackle any roofing or metal cladding project.”
“We selected Graham Hill Roofing for our 1000m2 small warehouse development in Rolleston in 2018. Not only were they clearly the lowest price but their workmanship, co-ordination and on time performance with our site foreman was excellent. They were the best subcontractor on the job. Foreman Harley and his team were outstanding. Its easy for companies to concentrate on their repeat clients and we aren’t a large repeat customer, so the very professional approach by Graham Hill was even more impressive, and very much appreciated. I can most definitely recommend Graham Hill Roofing Ltd.”
“Graham Hill Roofing’s staff and contractors have a good understanding of their obligations and requirements under health and safety, providing the necessary knowledge and equipment required to maintain their own safety and that of those working around them”.
“GHR have supplied and installed the roofing & cladding on several CIAL Rental Car facilities for Apollo Projects in the Mustang Park Development. They work seamlessly with us to ensure Health and Safety matters are addressed and managed. Their Installation team are robust and durable, prepared to work in all sorts of challenging weather. They willingly share limited site space with other subcontractors and are very good at cleaning up on completion, removing any excess and cut material from site. They recognise that ‘call backs’ cost all concerned time and money – we have experienced very few. We are certainly happy to endorse their work.”
“The high quality of the finish achieved was excellent and we have received compliments from our client for the high standards of workmanship delivered.”
