Mamabird, that's quite a story regarding the paint that didn't adhere to your kitchen wall. Without doubt, grease/grime was the culprit. For what it's worth, I use a micro-sponge to clean my walls and ceilings in preparation for painting. It's shocking how much invisible dirt comes off on the sponge! After that, I wash walls and ceiling with Soilax, an old time product known to facilitate paint adhesion. The Soilax label claims that one washing is sufficient for excellent paint adhesion, but I seldom wash the walls/ceiling less than three times. This might sound like overkill, but it works.

Apparently painting roofs is often done in your area but I have no first hand experience with it. I've seen reference to an elastic acrylic paint but not sure what is recommended these days. I suggest you contact major paint companies and ask for names of roof painters, then ask the painters for referrals of previous jobs so you can check their work. Since you're getting rid of the pink in the roof, be careful of the amount of red you bring in with the pavers. Also make sure the design of the pavers goes with the style of your home.

I get highlights and lowlights every 6-8 weeks for about $150CAD. I have a fair amount of grey (enough that it's a "percentage" of head now instead of just "a bit") and I keep a lot of the grey in with the other color. My hairdresser also leaves my part natural which helps extend the length of time between color sessions. I am terrible with my hair but have gotten a few compliments on the color - people seem to like the mixed grey/blond/brown approach! I always get her to cool down the highlights as my natural color is very cool ash and the grey is obviously cool as well. To my mind it's better for a lazy person like me than a full head of color because when lots of grey grows in, you get the "barcode effect" around your part, whereas this way the grey growing in looks a lot more natural. I tried going 100% natural with the grey and brown but it ended up looking very dull and flat - my grey is dispersed too evenly and just made my whole head look taupe. I wish it grew in big chunks instead! I have gone too long (about 2 months) with lots of sun, sand, and salt in the hair and it has lightened up considerably over the summer. I need to go in for fall lowlights soon! Here's a photo showing the multicolour approach including a lot of grey.

Sometimes it happens. Just be aware that the varieties with white flower phenotypically similar but genotypically different. There are two groups: the recessive white (they are always white) and the dominant white (they have a dominant inhibitor of anthocyanin pigments), that these sometimes give weak staining anthocyanins.
