"Green Roof Choice, It's Not About The Colour"


Don't worry, readers, it's not about the colour. As you know so far I’ve been posting either of green topics or roof on its own. You might now realize that these two are indeed my main concerns when I’m writing this blog. But today, I want to write both. Yes, both. What can be a better combination than these two? :) :)

As seen in this post’s title (thus you decided to click on it and read further), there is an option for doing a green roof. When you talk about “green”, there must be some key words that automatically cross your mind. For me, they would be something around healthy, environmentally friendly, harmless, good for people, sustainable, and all other “better and good stuff”. Don’t you agree?

There are many options when it comes to roofing. As I said in my earlier post, home owners can choose a range of roofing material from metal, slate, concrete and of course, clay. The question is, which of these materials is qualified to be called “green”.

Quoting from an article I found, “Clay tile wins points for green building on several fronts: It's reflective, it's ventilated and it's actually made of earth”. I couldn’t agree more to be honest. And another point is it can last for centuries which means no re roofing is needed for a very long time. No wasted energy and if at the end of the day you feel like changing your roof, the old material is always recyclable.

That is how clay roofing material (or terracotta as we prefer to call it) works in general. With its natural attributes come its advantages that make it superior compared to others.


Scientifically speaking, clay roofing tiles are rated so well on the system called Cool Roofing Rating Council (CRRC). CRRC is an independent rating group that asses how cool a roofing material is. According to them, a material is still considered cool even though it has a low thermal emittance. Whilst, clay roofing tends to earn very high ratings for thermal emittance. Okay I’m pretty sure I made you confused with all these unfamiliar terms. But basically what they’re saying is, even though the light is not bouncing off the tiles, clay roof will release the heat back very well which makes them a green roofing choice.

No other material can be more “green” I guess?  ;)


Now let me tell you one thing I find it so interesting. Apparently, we can actually maximise its natural ability of being green by choosing the right shape. Yes.... those manufacturers create some different profiles and shapes not only for eyes. There’s a reason of shaping them into different profiles so that people can pick out the most suitable one to complete their houses.

I just knew myself from this article that amongst all, curved shape roof tiles allow for superior ventilation. The effect of this is that hot air wouldn’t be trapped between the material and the roof in summer. Its weight that is considerably heavy also helps to insulate the home all year round. Amazing? I think so.


So.......... good news if your roof is curved and is terracotta, Australia! Because I gotta feeling it’s gonna be a very very hot summer this year :(
