They do not realise how much more energy they have to use to cool their house's. And how much they save in winter. We seem to get plenty of winter sun nowadays and the central heater isn't on at all after it is used first thing in the morning to warm the house up. Last summer we used our split system a/c only a handful of times (we only had one 40 deg day) but as for that extremely hot summer 3 years ago, EVERYONE was using their split systems, black roof or not.

Re: Which roofing solution to use for coolest house? 14Oct 04, 2011 7:11 pm ^^^Eager, our last two houses have had black rooves ( this one is Surfmist-so white) and this house is by far the warmest we have had in the winter-because we planned for the windows to catch as much of the low winter sun from sunrise to sunset as possible (passive solar). In the Summer when the sun's arc is higher is doesn't hit the glass as much but belts down on the roof instead-ergo the lighter roof works better then.

PPL in Tas may want a warmer house where up in darwin it needs to be cooler. I just figure with a planet that is getting warmer each year it's better to have a cooler house. Re: Which roofing solution to use for coolest house? 16Oct 10, 2011 7:41 am Here is a link to a government paper after research into insulation effectiveness and total r-values of different roof/ceiling/insulation scenarios. They don't cover light vs dark coloured roofs but you can probably dig those figures up somewhere. Maybe the Colorond site ?
