Architectural shingles are quickly becoming a favorite material with builders and homeowners. They give the look of wood or slate with the added benefit of being algae resistant. They come in a variety of colors. If possible, get shingle samples to bring to your home to see how they look against the colors on your house. Different light directions and different times of day will give different effects. If you like the look of cedar shingles, try brown or the reddish brown combinations. For the look of slate, you can use the shingles in arrangements of gray, black and blue.
