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

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/

Hope you've been able to use all our inputs! I've never noticed the surfmist roof to be dirty looking - my neighbour is always swearing about the bird poo on her darker roof. The fence is a lot closer than the roof for noticeable bird doings, lol. It's not quite white, anyway, it's got a silvery off white thing happening. Our winters don't really get below 1 or 2 c at night and that's pretty rare. It's usually an average of 7 or 8 degrees at night and 14 to 16 in the day. It's very Mediterranean - long hot summer and short wet winter... The winter is pretty mild altogether... I'm still working with some succulent cuttings at the moment. Our winter would be like an Autumn in say, the UK? Our Autumn time in Adelaide is when we plant a lot of stuff that others would put in in spring. Otherwise they just fry and die if spring planted, the UV is insane, they need winter to acclimate. Our grass is dead in summer and grows in winter... backwards! When we built I did a cactus and succulent yard with no lawns - grass is black hole to put money in, down here!

It looks like Windspray to me. Lovely colours on this house
