If you're building your home from the ground up or are doing some major remodelling to the outside of your house, you'll want to coordinate the roof colour with the hues of brick, siding or stone for the home's exterior. A grey will complement a number of warm and cool colour combinations and can add particular balance to several vivid shades.
Pastel or sky blue makes an attractive house colour when the roof is a dark or medium grey. The blue and grey combination is especially attractive on a cottage-style home since parts of the roof are angular and will directly contrast with the front and side of the home, easily displaying the two colours. A modest shade of blue with grey tinges looks good with a grey roof as well; it gives the home a uniform look while showcasing a subtle hue that makes the house appear a little larger.
Bright shades of yellow are ideal if the house has a dark or charcoal grey roof to create a pairing of bright and neutral colour. Pastel or light lemon yellow siding adds a little more refinement to the whimsy of a vividly-coloured home and complements a slate grey roof exceptionally well. Adding grey accents to the front of the home, like pillars made of grey stone or a dark grey door, will help to further balance the colours and add sophisticated style to the warmth and happiness of the yellow hue.
Black or dark grey
A house painted an ash-like black shade or a darker shade of grey than the roof is sleek and modern. You can offset this monochromatic look by painting the front door a striking shade of red like ruby or cranberry to add a pop of colour that will make your home one of the most attractive on the block. Further enhancing the grey and black scheme can include painting the door a charcoal grey when the brick or siding is a lighter shade or adding black shutters to the windows as a complement to the grey theme.
Muted or medium red
Grey and red look good together because they are the combination of bold and understated colour. A muted shade of red like a blush or intense pink is visually appealing for home siding and bricks and can even make a medium grey roof more noticeable. A more intense red like cherry will stand out on a house with light and dark grey bricks and a charcoal grey roof. If the entire house is painted red, offsetting the colour with shutters and a front door in a blackish shade of grey is elegant but eye-catching.
