Copper gutters are the heart of this new upscale rain gutter market, since copper trim can give a house a rich, luxurious appearance. Copper gutters are especially popular for luxury French Manor and Tuscan-style homes. Copper is more expensive than the aluminum traditionally used in rain gutters, which is why copper gutters have so far been limited to the luxury home market. Sock Woodruff is founder and partner of GutterSupply.com, the leading manufacturer and distributor of Copper Gutter.
