Southern Highlands | Denair Services

45 Years of Business and we’re not stopping here!

Like many small businesses Denair Services started out as a backyard operation run by one man. Today we are celebrating 45 years, 3 generations and a local workforce of administration, roofers and labourers coming through our doors.

The company has come a long way since its humble beginnings with blow-in insulation, including many exclusive contracts for the Southern Highland Region. Some of the brands we are proud to carry and be able to offer to our customers include CSR Bradford insulation batts, Colorbond roofing sheets, Proclima roofing membrane and Velux skylights.

Of course, our offerings also extend to a large range of tools and hardware’s that can be purchased directly from our showroom in Moss Vale. Some of the items you’ll be able to find in stock and available now include Midwest Snips, Kapro Spirit Levels and Ullrich Aluminium Planks.

But that’s not all we do! Luckily for us it’s much more automated these days and there’s no jumping on large guillotine arms or manually bending and moulding flashings. While we have off-the-shelf items available, we can also make custom flashings to suit your specific measurements. Our Workshop team is well versed in executing the more difficult of tasks with ease, including the more eccentric of requests such as an ‘Outback Dunny’ . Yes, that’s right…we made a loo!! And to be honest it looks pretty fantastic! Check out the photo below.

It’s not just all about the showroom and warehouse though. Throughout the last four decades we have built a network of local and reliable builders to that use our products. Plus, our team love nothing more than to get onsite and help a customer realise their dream build. Whether you want to modernise your roof, restore your barn or do a complete new build our team can help with the process.

As we mentioned above, Denair is now welcoming its third generation of Chesterfield’s with Vicki and Jake working and helping to guide the business well into the future.

While the 2nd September 2021 marks 45 years in business, the month-long celebration will be one not to miss. We want to thank our loyal clientele for their on-going support, as well as welcome all the newcomers to the fold.

Belmore Falls Construction Project

Our team love being able to share our finished projects with you, but… what about those projects that are underway and take a longer period to finish?

One such project is a property that is currently under construction in Belmore Falls. Located in the Southern Highlands just outside Robertson, Belmore Falls is a beautiful bush area, that is known for its natural beauty, however it does have its own specific considerations when it comes to construction.

The first consideration is that all buildings must meet the standards for bush fire ratings. What does that mean? If your property is located in a designated bushfire prone area, your new home has to comply with the bushfire construction requirements of AS 3959-2009. Which means that the construction materials need to be non-combustible and fire resistant.

So, back to the project at hand. The construction is being completed over 3 stages by the wonderful builder, P.M. White Building. Speaking with the team from PM White, they have noted that this is one of their biggest projects to date but they are loving watching it all come together.

The three stages for the build are the garage, barn and guest house, and the main home.

During stage 1 we were able to partner with PM White Building to provide the guttering and custom mitered downpipes, as well as the wall cladding for the garage. The material of choice for this stage has been Unicote LUX Weathered Iron.

Stage 2 was focused on the construction of the barn and guest house. Not your usual outback building, measuring at close to 50 metres long the roofing utilised the Unicote Monolith Matte 480mm wide snaplock standing seam roofing, and a whooping 200mm half round gutter with custom mitered downpipes.

The roof on the Barn building also featured four cupola’s which were prefabricated on the ground with their own small roof, and then were hauled up onto the main roof and put in place.

Of course, being a little unusual and needing to stand the test of time we suggested the use of Proclima Solitex Extasana membrane onto plywood for the roofing. It’s a vapour permeable (class 4) self-adhesive membrane and has shown to be lighter than other membrane products on the market. The Solitex Extasana is also a 180 day UV resistant membrane that can be left in open air, as it is water tight, weather safe and UV resistant without compromising the structural integrity. This meant that our roofers could install the roofing sheets a week, or even month or two after the membrane had been installed, allowing the builder to continue with interior construction without the weather prohibiting progress.


Stage 3 is under way with the earthworks for the basement happening as we go live with this blog. We look forward to bringing you more updates and photos as the project nears its completion.
