I have a dark tile roof Only choice that was available, but I did put sarking in.. so I hope that helps. Re: Light vs Dark roof temperatures 6Apr 11, 2016 8:59 pm Would be interesting to compare white tile (Monier Vodka range or similar) with white colourbond. I would bet that a white tile should be better.

I would bet that a white tile should be better. Probably not, as during summer it would release heat back in to the roof as it cools down... just like bricks store the heat for later release. My roof is Surfmist colourbond roof. Owner Building at Jimboomba Woods in Logan City Qld. Blog : http://bandlnewhomebuild.blogspot.com H1 thread : viewtopic.php?f=38&t=68283 . Re: Light vs Dark roof temperatures 9Apr 11, 2016 9:32 pm bpratt Probably not, as during summer it would release heat back in to the roof as it cools down... just like bricks store the heat for later release. My roof is Surfmist colourbond roof. well tile should release the heat with some time lag (less lag than brick though), meaning this heat will be released evenly at night. However, colorbond will transmit absorbed heat straight to the air of the underroof space almost with no lag. So actually hard to say, yet intuition tells me white (not gray) tile should win. In both cases the white layer will keep warm from being emitted back during night.

I have read one report that concluded that in Melbourne and further South, that the benefits of a dark roof in winter offset the disadvantages in summer. A dark roof does help in winter, but with the lower sun angle and fewer sunny days, it won't collect as much heat in winter. Then it's not so much the sunny days when you need heating anyhow. But still, dark does have some advantages. Stewie D How did you do the measuring ? I logged one house with an Elitech RC-5 temperature logger. It costs around $20 and seems to work quite well logging data for several months. For the other one I used cheap wireless weather station transmitters and logged them to my PC using a USB TV tuner and the RTL433 software. It could be interesting to get a few of the Elitech loggers, and ask some neighbours with different roof types to put them up in their roofs, and then compare at the end of the season. Re: Light vs Dark roof temperatures 11Apr 12, 2016 4:04 pm I'd be interested to see the difference between three light coloured roofs of the same type eg Colorbond surfmist - one without sarking, one with and the third with a decent blanket like you have used in your new house.
