You've really got the "old wood" technique down pat, Richard. 
For colouring the shingles, I used various colours of well-thinned paint applied with a flat brush. Start at the top and brush straight down, using a very light touch to avoid colouring the entire shingle. I used Floquil, including some FloStain, and colours included browns, greys, greens and reds, along with silver. Wood shingles usually darken after they're first applied, then turn grey and become lighter, eventually taking on highlights of silver. While all that's taking place, dirt from the atmosphere is collecting, along with stains from chimneys and flashing - these latter ones are usually visible as streaks emanating from the lower edges of the item causing the stain. Unless the climate is really dry, you'll also see moss and sometimes other fungus-like growths - these can be quite heavy where the roof is well-shaded. I just keep layering on the different shades until I get a look that I like.
