Light grey siding
Treat it like a white house. Black and charcoal roofs make it modern. Brown and weathered wood warm it up. Almost nothing fails on light grey except a light grey roof, which makes the house look like a single unpainted surface.
Medium grey siding
This is where contrast matters. A black roof works. A charcoal roof can be too close to the siding and lose the roofline. Brown, bronze and weathered wood are underrated here, because the warm roof stops the grey from looking cold.
Dark grey or charcoal siding
A dark house wants a roof that is either the same black for a monolithic modern look or a clearly different colour. Bronze, copper and weathered wood all separate the roof from the walls. Medium grey looks like a mismatch.
Blue and green undertones
Many greys lean blue or green. A blue-grey house takes a black or slate roof. A green-grey house takes brown and bronze. Hold a white sheet of paper against the siding to see which way it leans.
Metal on a grey house
Standing seam in black on grey siding is the most requested modern combination we render. Galvalume, the plain silver finish, also works on grey and is cheaper than a painted panel.
Check it on your own siding
Grey is the colour most affected by its undertone, so a chart is nearly useless. Upload a photo and try black, brown and bronze. The render keeps your siding exactly as it is.
