“We had looked at lots of different options for our space before we decided to go with The Outdoor Room Company. We wanted a solution that gave us a classy looking, permanent roof structure, which retained internal light inside our house. Blending an old style house with a modern structure was a risk, but we are thrilled with the result. I appreciated the collaborative approach to the project, and the care the team took to complete the work to a very high standard.”

- Rosemary from Hillsborough

“We absolutely love our outdoor room. From start to finish the team were fantastic. It is wonderful having such a versatile living area, for rain or shine! We are thrilled with the quality and look of the space - it ties in perfectly with the rest of our house. We are so glad we found you guys, thank you so much Outdoor Room Company!”

- Bridget from Welbourn

“The Outdoor Room Company have been wonderful to deal with from start to finish. They are responsive, knowledgeable, had attention to detail, considerate, went the extra mile, left the site very tidy, and were patient with our dogs that found the tradies onsite a bit too exciting! They’ve created two extra living spaces we can now use that we never utilised before, and both roofs have lowered the stifling summer heat in our house, much to our relief, without blocking the natural light. We would highly recommend the team to see what magic can be done at your place!”

- Jenn from Vogeltown

“Absolutely love how the louvre has transformed our outside area. Joe guided us through the process, providing advice on size, colours available etc, coordinating installation with our electrician (we added lights to the louvre), and with our concrete installer. Very professional service. Looks fantastic and I can see us using this area so much more!”

- Joanne from Whenuapai

“We’re ecstatic about the job The Outdoor Room Company have just done for us! A beautiful lofty flat roof over our deck allows plenty of light and weather protection. Four mesh blinds can be raised or lowered to manage whatever conditions arise, so blazing sun or a sudden squall, the BBQ continues in comfort.The team were a pleasure to work with. Attention to detail, quality workmanship, and superb materials all contributed to make an additional outdoor room that we are loving already.“

- Barbara from Onehunga

“The guys at the Outdoor Room Company did an amazing job for us. A really good outdoor space is now a GREAT outdoor space. Honestly, the louvre roof has really transformed our home. It is the best decision we have made! A great experience all round with these guys - professional, friendly and trustworthy who left us with a premium result. I highly recommend their product and service.”

- Nick from Mt Eden

What is the outback flat roof?

The outback flat roof is a patented fixed roof system that is a self-supporting structure, due to the way the tongue and groove steel sheets are made. This removes the need for bulky support beams and purlins, which traditionally become home to spiders and birds.

The design of the connection between the light-diffusing PVC panels and the high-tensile steel sheet solves the problem of grime building up in every valley of a traditional clearlite roof structure.

What maintenance is required for the outback flat roof?

No one wants to spend their summer cleaning their covering.
The outback flat roof requires minimal upkeep, with an annual wash to keep the space feeling fresh and clean.

The materials used are high-tensile steel manufactured with a colorbond-like process, ensuring the colour is baked into the metal, making it resistant to scratching and imperfections.
The light-diffusing panels consist of 4mm thick UV-rated PVC, which are slightly arched, to help keep them clean by washing the grime onto the steel sheets.
