Heat Reflective Paint & My Roof
How's your roof? Is it secure and rot-free? Or does it need some TLC? This is a short article on how I brought my roof back to its former glory.
I don't know about you, but I found the storm we had at the beginning of July scary. My whole roof seemed to shake! Thankfully my roof stayed in place and weathered the storm. But it got me thinking; I better give my roof a little tender loving care.
Firstly, I thought I better start with the typical repointing and re-bedding. I've done it quite a few times over the years, my father and I used to do it regularly, so this was easy.
Of course, before I did anything, I checked for loose or missing roof tiles and ensured there weren't any leaks or rotten timbers. Thankfully the roof is old but sturdy. So you can see that regular roof maintenance had been a priority even before we moved in.
The next step on my list was painting the roof. It's one of those old cement tile roofs, and it was starting to show its age. A friend of mine had told me about heat reflective paint and how it helped keep the house cool in the long hot summers. It sounded like snake oil, but I thought I'd look into it.
As always, I started Googling; I read up about it on many forums and read many websites from paint manufacturers. Finally, it started to seem like the real deal. Many people were saying it also helped keep the heat in over the winter, but the official sources said it only kept the sun out. This seemed more logical, as white has been used for centuries in warm countries to keep houses cool, but I couldn't see how it kept the warmth in. But I kept on doing my research.
I heard great things about the Shieldcoat Thermobond Heat Reflective Paint. However, what most stuck out were things like:
- It's 100% Australian-owned and manufactured, making it the best from the intense Australian sun.
- It's environmentally conscious and compliant with The Australian Paint Manufacturer's Federation's stringent health and safety regulations.
- 10-year warranty against peeling and cracking.
How Heat Reflective Paint Works
So I started to investigate that brand specifically. Thermobond guarantees that it can keep the roof cavity to just a few degrees higher than the outside temperature. If you've ever been in the roof cavity on a summer's day, you'll know it mostly feels like an oven up there! And if I can keep the roof cavity temperature down, it should help the whole house to be cooler!
In my quest for knowledge, I found an article called Aussie Roof Maintenance: Tiled Roofs. It pointed out the pros and cons of heat reflective paint and the basic steps needed to maintain my roof. So if you're thinking of painting you're roof, give it a read; it's not very long and quite enjoyable.
So, I took the plunge and ordered the paints I needed. Apart from the heat reflective paint, I also bought Shieldcoat's SHIELDSEAL W to seal the tiles first and the hopper spray gun the article talked about; it speeds up the whole process of painting my roof.
It took me two full weekends to repoint, re-bed and paint the roof, but its worth it. There's less chance of my roof flying away, of rain or vermin getting in, and next summer, we'll see if the heat reflective paint does what it promises.
