Hi there Mary, that's something I hadn't thought of re painting the ridge tiles, I had thought to replace them with the grey, it would depend on the condition of the ridge do they need re setting, this would be a good time to replace rather than fiddle with painting, Woodland Grey is a classic Colour Bond, Gully a bit lighter. Your Roof is a strong red colour, I would get a sample of both grey colours, if you have a spare red tile take it with you to look at samples good luck

Personally I'd use Manor Red. Probably won't see a lot of it anyway so if theres a discrepancy between Colorbond and tile it won't be as obvious. I'd also guess that the Manor Red would be a darker red than the terracotta tile? Could use Basalt for gutters and facias if you want a bit of grey perhaps?

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/

Yes go monument!and if you go for some lime acacias out the front (tall weeping or the low bush)it would brighten up you whole look.Also adding strappy green plants that bulk up would give it a bit more of a clean look. If you don't want to go monument on roof go a light grey and tie in with a couple of tall light grey planters on either side of your door. Pleas please please!find someone with a jigsaw and cut the tops off your pickets to give a cleaner look before you paint them. I'm stating the obvious but those security screens are pretty overwhelming,can you just have them on windows that can be opened,it might not look so busy out the front.
