A commercial building can benefit a lot with the right design and materials. Facades, walls, and other parts of the building might be able to create an impression of the whole building. However, a building’s roof tells a lot to the people inside the building.

Even if roofs are not that visible from the ground level, this specific part of the building can determine the overall structure of the building. In particular, the insulation of the roof can change the way a building holds into the integrity of its composition. This insulation can also affect the energy consumption of the building in a huge way.

Roofing insulation is essential to every commercial building since it produces the following outcome:

Serves Like a Protective Blanket

The roof surface and roof deck of a building have a layer in between that uses different materials for roofing insulation. These insulation materials include polyisocyanurate, extruded polystyrene, expanded polystyrene, mineral wool, spray foam, and fibreglass. With these materials, your roof can reduce the transfer of heat in and outside the building. On hotter days, your roof insulation will trap heat so that you won’t feel the direct outside temperature. Alternatively, your roof insulation will reduce heat loss during the cold season, which is a good thing for the entire building.

Prevents Growth of Moulds

Another great thing about roof insulation is that it prevents moulds from forming in the roof and even other parts of the building. They cannot survive the temperature and moisture of a building with roof insulations. However, there are cases that moulds still grow on the roof, but the layer of the insulation is thick enough to block the moulds from entering the surfaces that are visible to the building occupants.

Saves Energy and Electricity Bills

Since roofing insulation regulates the temperature of the building, some equipment and machinery are not required to run regularly basis anymore. Buildings where the roof insulation can effectively manage the heat distribution of the whole structure can save a lot of energy from the frequently equipment that used to maintain temperature. Moreover, the efficiency of the roofing insulation can hugely cut the electricity bills of business owners.

Lessens Carbon Footprint

Most buildings in Australia are built with careful consideration and elegant architecture. Moreover, property owners construct buildings that follow simple yet sustainable guidelines for a more safe and thriving environment. The installation of roof insulation can lessen carbon footprint that combats air pollution. With occupants reducing the use of electricity in general, their carbon footprint is now lessened for every occupant that works on a commercial building with roof insulation. This factor attracts business owners in leasing a commercial building since they want to comply with the ethical standards of a working environment.

As more and more countries are beginning to appreciate the wonders of renewable energy, different companies and households are now switching from coal energy to solar energy. Using such energy as a source of electricity is a good thing not just for the consumer, but also for the environment. Households that go green enjoy cheaper electricity, and at the same time, avoid the use of non-renewable energy like coal and petroleum as their primary source of fuel and power.

Many houses and buildings have adopted the use of solar energy at the expense of buying and installing solar panels on top of their roofs since the solar waves have almost no obstructions out there. However, you may want to hold your plans of buying solar panels and consider first the best roofing material suitable for your existing house or building.


Tiles are made of different strong materials that can last for a very long time, which made them the most common roofing material in Australia. As common as they seem, installing solar panels to them may take some thorough work. The solar panel installation with tiles includes the temporary removal of tiles, drilling of steel mounting brackets to the rafters, cutting some tiles, and reattachment of tiles.


When it comes to solar panel installation, metal roofing is considered the best type of roofing material. This is because the installation requires minimal work and zero drillings into the roof structure. Unlike tiles, metal roofing has roof screws that can be reused for the attachment of solar panels. This type of roofing material can certainly speed up the installation process of solar panels and cut down cost.


Another roofing material that can save a lot of time and workload in installing solar panels is composite. By just sliding the footings under the composite shingles, they can easily be secured to the rafters to which the solar panels can be attached afterward. They can withstand the weight of solar panels since they are durable and flexible, all at a cheap cost.

Tar and Gravel Roof

Homes with flat roofs often resort to using tar and gravel roofing material. This kind of roofing entails the use of hot tar, roofing felt, and some mineral coatings on its sheet layers. Incorporating solar panels to this kind of roofing requires additional brackets that can be tilted at a certain degree to catch sun waves. Although the installation procedure is easy, the cost of the tilted brackets and braces may be expensive. Still got questions about the best roofing material for your solar panels? Johnson Roofing can help you with that. We have done new roofing services to a lot of households in Australia and continuously serve more and more clients. Take note, installing solar panels does not translate to new roofs. Sometimes, you just have to re-roof to save you a lot of time and money. Luckily, we also offer re-roofing and roof maintenance.
