Gal will go grey (mid to dark grey) over 12 - 18 months. Initially VERY bright. The energy absorbed changes accordingly, from sub 5% absorbed to ~35%. Zinc maintains brightness for longer, though still suffers some dulling. Say 5% to 15% over time. This can be avoided by coating with a product called 'Sharkhide' metal protectant, used to stop aluminium boats oxidising. For there reasons many councils will not allow zinc or gal roofing (visual amenity, reflection issues), while making the houses more prone to requiring summer aircon at the same time. Surfmist Colorbond starts around 9% absorbed. If purely for energy reasons, a light colour might be the only option. If going dark, I would suggest at least doing the 'less aesthetically important' sides and rear in a light colour. Your call. If you go all dark, ensure you have good roof space ventilation for the summer that can be closed in the winter, and lots of well installed ceiling level insulation. Spray foam is more reliable over time than batts, see Spray It Solutions or similar (they have the Formaldahyde free Canadian Icenene foam).

Ahh, JEC, I did not realize I was Australia! Very sorry! Yes, I'm in US.(wish I was there sometimes, especially since 11/2016). Anyway, so oklouise tried to help me but I assumed she was here and then I was wondering where she shopped for materials that actual, knowledgeable and experienced advisors! Sorry about that Mrs. Oklouise! I appreciate the help too. It was only a small part of it I didnt quite understand and that's simply because oklouise is not here. I am positive if she was, she'd adapt to the ways and how they do things here. So, come on over mrs oklouise! You're welcome anytime! Siriuskey, yes they "paint" the cedar here, but they use solid color stain so it looks like paint. I am positive though that there are cedar built things with actual paint. But that's really a no-no with cedar. After it gets older, some transition to semi transparent stain, then, when even older they go to solid colored stain. Wish I was a pilot! mpilot1 was made for me by my company years and years ago as their name had the word pilot in it; since they already had a "marc" there when I started, they gave me marcpilot1. They've since closed(after 40 years), since I had had it for so long at that point, I took the name/address with me. Think I should put some of the after pics up, like when I finally finish this project for mother? Thx again for all help, especially oklouise! God Bless.

I really feel for you. I had a similar experience when a neighbour recommended someone she knew who was 'really good'! He was extremely lazy and, apparently, suffering from depression and he had split up with his girlfriend! He did a dreadful job which took a week - because he was too depressed to work on some days - he only did about half the job and I wasn't impressed. It has ruined my relationship with my neighbour because she knew him to be really good. She won't even come into my place - I assume she doesn't want to see the mess he created! To top it all off (I had paid him cash - fortunately only half of what he 'wanted' (not 'earned') so he wouldn't be paying tax on it )- I didn't get a receipt. He also took my house keys so I had to have the locks replaced. Such a mess and then, I had some tradies through a couple of weeks later for an unrelated job and they asked me when I was getting the place painted? When I told them it had just been done, they really didn't know where to look. I seem to constantly get ripped off, so I'm not getting much done any more - too expensive and depressing.

Have a look at the planning approvals on the local Council’s website. These have dollar estimations on them. That will give you an idea and also give you the names of some professionals that work in that area. Bonus that you can drive past the projects and see what they turned out like.
