Gutters and downspouts can be easily obtained as standard household construction materials,or they can be specifically designed to enhance a building facade and maximize the amount of harvested rainfall.The materials for gutters and downspouts range from vinyl
and galvanized steel to aluminum,copper,and stainless steel.Gutters should typically be square,rectangular,or half round in shape and,at a minimum,5 or 6 inches wide.They should have an outer edge higher than the roof-side edge,have splash guards at roof valleys,slope towards downspouts at one-sixteenth to one-quarter inch per 10-foot length of gutter,and be installed per manufacturer’s guidelines for hangers and connection points (approximately one bracket every 30 inches).
排水沟和落水管作为普通的家用建筑材料很容易获得,或者它们经过特殊设计可以加固建筑物表面,使排水量最大化.排水沟和落水管的材料包括乙烯基、镀锌钢和铝、铜、不锈钢.排水沟通常是正方形、长方形或者半圆形,至少5、6英寸宽.它们的外缘要比屋顶边缘高,屋顶排水沟要有防溅水功能,而且每10英尺要向落水管倾斜十六分之一到四分之一英寸.同时要按照生产商指示安装挂钩和连接点.（大约每30英寸一个支架）
