You will struggle painting pebble dash
rough cast or wet dash is paintable
Or you could go with a silicone render with 3mm stone that would look very close to what you already have plus you can get it colour matched
Looks like you have a smart roof on which someone has cut the ceiling collers short if it's for light storage I don't see a problem also it will be insulated with in the roof panels so no need for extra
Smart blades are good now I see they have this good deal too
