Each home and property is obviously built differently – though did you know that depending on how the structure is built it could affect the temperature inside the home or property? One big factor that does affect the degrees is the roof. It plays a big part on the insulation. Sydney’s weather can range from under 10 degrees in Winter to over 40 degrees in Summer. Here are the 5 main roofing elements that play a part in the coolness of your home.
1. Roof Colour
Going back to basics – remember in the early years of school where we learnt that dark colours absorb light and lighter colours reflect the light away? Well, the Sun’s warm rays are more potent in darker colour roofs as they absorb more light thus more heat – typically by more than 5-8 degrees than of a lighter colour. So when choosing a darker colour think about insulation. But if no other colour suits the rest of the home – then there are other ways you can better insulate.
2. Type of Roof Paint
So you probably might’ve chosen a darker colour or even a light colour, but you want it to be even more effective in insulating. The roof paint used is also a big driver on the temperature of your home. There are very high quality roof paints that are specifically produced to keep the roof cooler and reflect more heat. You can give your local roofer a call to enquire about their heat reflective roof paint range and its effect and use.
3. The Material
Similar to how the roof colour absorbs light, the roofing material is also a factor, as you can imagine different types of materials absorb different amounts of heat. Terracotta, concrete, and stone are quite dense so they store more heat whereas thin roofs like metal roofs can heat up quickly though they are the quickest to get cool. So you could imagine the possibilities you can choose – so if you still prefer a thick roof for the sections of your home, you could apply heat reflective paint to balance it out slightly.
4. Insulation & Ventilation
Even with all the roof colour choice, material and paint, it is ideal to still have additional insulation under the roof and inside the home. If the insulation and structure of the roof is built correctly, it would promote great ventilation not only in the attic but also within the living space. It should allow hot air to flow outside. Your typical roofer should also be able to do this for you.
5. Additional Roof Parts
Moving even closer towards an eco-friendly and greener living, whirlybirds and other vents can also impact the insulation of your home. These products are designed to remove the ceiling heat and release it into the air while allowing cool air in. But, having just 1 whirlybird would probably not be enough – it is ideal to have more than 2 for a noticeable impact. These type of ventilations are also affordable to install and have no running cost. So if you are not bothered by the appearance of these – it is a great choice. So the next time you are thinking about restoring your roof or painting your roof, consider these factors for a long-term and more greener way of living.
