I understand going with the grey since it is an 80's style house. You could also do bright bold colors. I do not know if that is your style. I have attached a quick rendering of the gray scheme you mentioned. I prefer light colors above dark colors. This keeps in theme with the sky and earth. Makes the house seem more grounded. The dark entry also draws your eye to it especially with the light coming from the other side of the house. I have also attached a quick rendering of a blue scheme. It looks like you are on a beach and I thought this would blend in with the surroundings. If that is what you are seeking. Hope this helps.

Pictures would help...are you planning on getting a new roof or is it staying? If it's staying, is it tile, shingle, metal? And what region is it located?

Thanks Courtney for the suggestion! Will grab of a sample of the colours and take a closer look. We like a Tranquil retreat or grey pebble but not really not sure about which tones is appropriate, especially if going for the loft/industrial look with black windows. Tried goggling red brick, terracotta roof, black windows and couldn't find much.

Nearly finished painting my cottage and I am wondering what colour roof I should go for? I could refresh a brighter red (Resene Pioneer Red or Scoria are available) or go for a charcoal gray to match the trim?f thoughts?
