Hi All, well I've been test painting for days and still so unsure. I think the hardest part is deciding on the gutters etc. In the top photo you can see from left to right. Dune full strength, then Jasper at the other end of same gutter, below that is a white called Surfmist and then there is monument on the lower gutter. I quite liked the monument on the gutter but when tried on the wooden fence it was clearly going to be too much darkness and didn't look good. I'm currently trying Jasper on the fence and other areas but its really a brown colour and again over a large area not sure its going to look all that nice and maybe too dark. When trying lighter colours, white and off whites on the trimmings they looked far too start on the dark roof so I think white/s are out for gutters. Can you have a different coloured fence (wooden panels) to the trimmings on the house? I've been assuming they need to match. I'm fairly happy with half dune on the walls. Any other suggestions for trimmings or thoughts on the colours in this photo? Its doing my head in now!! Second photo was house with lighter colours on the gutters - surfmist and dune I think. I tried a vivid white but it was crazy wrong.

I just googled & found this site, which quotes cost of R2.5 75mm. there are other suppliers as well. What was quoted to you for cost of roof installation, and was it itemised so you can see exactly what thickness the foil-backed insulation builder will use? I'm guessing the thinner (lower R factor). So, the new quote should reflect a credit for the cost of previous insulation, since it won't be used, then cost of thicker insulation added. Does that make sense? If you are unsure, best to speak with the builder. https://www.pricewiseinsulation.com.au/product/heavy-duty-fletcher-permastop/

I recently completed my owner built house and shed. My shed has shale grey roof and walls and is very cool all year round in The Atherton Tablelands near Cairns. My neighbor used monument and has a very hot shed. My house has a shale grey roof and the walls are cement block painted with shale grey(Taubmans). The garage door and is surfmist which looks white. The window and door frames are white. I love the look and what ceiling space I have does not get overly hot. The shale grey roof appears lighter than the walls because of the reflected light. This gives a nice contrast. Another neighbor has a surmist roof which can be too glarey to look at. Bear in mind that monument being dark will also show more noticeable fading than shale grey.
