An unventilated roof space can be 20 degrees hotter ! Effective roof space ventilation is important for your health, home and pocket.

Make your home cooler home in Summer, and a warmer home in Winter, by simply installing in your existing roof a number of pairs of these ingenious unobtrusive 'hollow tiles', or for corrugated metal roofs, 'integrated units' fitted under the ridge capping. They create continuous convection currents to silently ventilate your roof space ! By reducing how often you may need cool or heat your home, you get FREE big reductions your expensive electricity and gas bills, as well as giving you a drier and healthier roof space, by minimising unhealthy fungi growing and minimising damaging condensation forming especially in Winter, which can be invisibly rotting your structural roofing timbers.

Have you climbed into a roof space? In summer it is like a sauna, and in winter it is like a butcher's cool-room. The reasons for this are that the roof space is like a container with a lid firmly on top, the sarking above on the underside of the roof, and below there can be ceiling insulation installed thus the air is trapped with virtually no air movement, even more severely in homes with continuous sheeting metal Colorbond roofs. The thin sarking sheet, with its reflective surface on the underside, is installed to try to minimise the outside temperature entering, not as is often misunderstood sheeting to prevent moisture from broken tiles or wind driven rain entering your roof space. So the sarking, like when you use aluminium foil to keep food warm, virtually stops the heat or cool escaping through gaps in your external roof, and the invisibly severe consequences of this trapped air is now elaborated.

In SUMMER this trapped air gets hotter and hotter becoming a 'sauna'. During the Federal Government's home insulation program, we were contacted by very concerned builder urgently seeking a solution to the roof space's temperature which had increasied by 20 degrees, after ceiling insulation was installed ! This fact was confirmed by an architect in one of the NSW Government property departments. How much additional running costs are you paying in summer, to have your ducted home air conditioning system operating in an oven ?

In WINTER unventilated roof space is like a cool-room making your home so much colder. It will require more heating and damaging condensation can quickly create mould and fungi, (bad for your health), and start rotting your roof timbers.

"Six months, later the house's walls and ceilings were sprouting fungus. When the roof manhole was opened, water gushed out like a waterfall. The new insulation was sodden, rendered useless by the installer's failure to ventilate the roof (space). The air is still toxic, there's black mottle specks all over the white plasterboard and a green tinge to the floorboards. The architect and lawyer who was called as an expert witness said the house was the worst example of condensation damage he had seen."

The need for and significant benefits of effective roof space ventilation are well documented in building research. This old and not widely known set of problems was even identified back in the 1890's by the famous Sydney architect William Kemp, who amongst other well known buildings designed the Sydney Technical College in Ultimo, and incorporated roof space ventilation systems in all his buildings.

Our range of these new roof space ventilation products, which were developed in Australia. By their simplicity of design, versatility and effectiveness, they represent a major breakthrough solution also due to the fact that they have no moving parts to fail, or to generate disturbing noise when needing to sleep at night and they are virtually invisible when installed. Additionally, they are easily fitted by roofers when they installing a new roof, or for exiting roofs they are easy to fit from the outside by a professional handyman or roofer. Every home and household in Australia would benefit from so many points of view by having them silently ventilating their roof space, day and night.

By ventilating your roof space, you can reduce your cooling and heating bills by up to 20%.

An unventilated roof space in summer means you are paying electricity costs to cool your home, while allowing your closed up 'oven' roof space to get hotter and hotter. If you have a ducted air conditioning system in your roof space, the indoor unit and the ducting branching to each room is operating in an 'oven like environment' and your running costs will be significantly higher.

An unventilated roof space in winter means you are allowing your closed up 'cool-room' roof space to get colder and colder. With this massive 'iceblock' on top of your home, your home will be significantly colder requiring more heating.

With electricity and gas costs continue to skyrocket by around 25 % every two two years. Now is the time to do something to reduce your energy bills and help your stretched budget.

With no moving parts, these products are silent and maintenance free, where as other forms of protruding roof space ventilation are noisy and their bearings will require service or replacement with time, especially those cheap rotating versions made in China. In a Canberra, a household saved 20% on their electricity bill in one year, by simply installing 4 pairs. The payback period was a mere 2 years.

These boutique products are not mass produced, but rather carefully manufactured here in Australia from quality Australian Bluescope Zincalume using laser cutting, and not with low quality materials nor low quality manufacturing methods offshore.

Ventilate your roof space by simply inserting these NEW waterproof hollow 'ventilation' products into your existing or new roof.

Our unique NEW roof space ventilation solution is available in two versions, one for metal sheeted roofs and the other for tiles roofs:

FOR COLORBOND / CORRUGATED ROOFS: A specifically designed hollow unit, whose side shoulders sit perfectly over two corrugated shoulders in a corrugated profile metal roof, which the lower apron is laser cut to sit onto the corrugated profile and the upper section slips straight under the metal ridge capping. When installed these compact and slim units are barely visible. This is a cool and effective solution for an otherwise 'hot tin roof'.

Be sure to specify Corrugated Colorbond roof for your project, as there is only one model, and it is only compatible with the corrugated roofing profile. This roof space ventilation Unit is not compatible with other metal sheeting profiles.

Simply install in pairs on either side of the ridge cap sheeting, which will enable your roof space to start silently ventilating. To work out how many pairs you may require, the first pair should be 1.5m from one end and then additional pairs approximately 4.5m apart, with the final pair again 1.5m from the end. This enables nature to take over and a gentle convection air current to commence to achieve the desired on-going roof space ventilation. We also have a solution for skillion roofs, using Intermediate Flashing, which we can supply.

When the hollow units are installed, they are carefully inserted though the sarking to become effective 'straws' thus facilitating air movement enabling the roof space breath and equalise temperature inside with the outside.

As you are installing these hollow ventilation units high up under the ridge cap and on top of the corrugated roof, they are virtually invisible, there is no potential water entry problem, there is no future maintenance required, they are silent and they are working even when there is no breeze such on a very hot still summer day. On the other hand, a 'whirly bird' type product is visually obvious and ugly, requires flashing which introduces the risk of water entry problems, requires maintenance to their bearings, when rotating they make noticeable noise especially at night when you are needing to sleep and they do not work when there is no breeze, at the very times when you need them most.

Either hand or spray paint to blend in with the colour of your roof, or we can have them powder coated to current and past standard Colorbond colours. If you have an existing Colorbond roof, remember the original colour may have faded. This highly effective product is ideal to be installed in new homes, existing homes, sheds, garages or when building an extension to your home.

FOR TILED ROOFS: Hollow tiles are available for both Concrete and Terracotta tiled roofs. Simply replace approximately 6-10 solid tiles with these hollow ventilation tiles which will enable your roof space to start silently ventilating. How to work out how many pairs you require: The first pair should be 1.5m from one end,  then additional pairs approximately 4.5m apart, with the final pair 1.5m from the end.

For each pair, the upper one is ideally located on either the Western or Northern side of the roof to allow the trapped air to escape, about 3 rows down from the ridge capping, and the lower one on the either the Southern or Eastern side of the roof about 3 rows up from the gutter. They can also be installed in skillion roofs. This enables a gentle convection current to take place to move the air and achieve on-going ventilation. When the hollow tiles are installed, they are carefully inserted though the sarking to become effective 'straws' thus facilitating air movement enabling the roof space to breath and equalise temperature inside with the outside.

As you are substituting solid tiles for hollow tiles, they are invisible, there is no potential water entry problem and there is no future maintenance need. They are silent and working even when there is no breeze such as on a very hot still summers day, unlike 'whirly bird' type products which are visually obvious and ugly, require flashing which introduces the risk of water entry problems, require maintenance to their bearings, make a noticeable noise especially at night when you are needing to sleep and they do not work if there is no breeze on scorching days, precisely when you need them the most.

Either hand or spray paint to blend in with the colour of your roof, or we can have them powder coated when you choose a colour from our extensive range. (Click to here See the Tile Compatibility Table)

These effective products are simple to install from the outside.

These roof space ventilation products are easily installed from the outside by an handyman, roofer or plumber who is experienced in working on roofs and roofing.
