Downspouts serve as the primary method to release water from the room to the ground. Imagine the surface of the roof as a drainage collection device that captures raindrops. As the rain hits the roof, it travels down the shingles to the edge of the house. Without collection gutters, rain would pour right off the roof around the foundation of the house. An integral part of the rain collection system includes water downspout parts in the form of gutters, connectors and tubes that direct water away from the home. These pieces work in conjunction.
Gutter pieces run along the length of the home horizontal to the ground. These main gutters serve as the primary catch basin for all debris hitting the roof and consist of U-shaped bent metal. Gutter pieces come in 10-foot sections for installation on the roof edge. Many builders angle gutters just slightly to encourage downward motion of water toward the downspout located on the corners of the home.
Elbows serve as curved pieces connecting the gutter to the downspout. This curved joint bends from the end of the gutter to attach to the length of downspout. Elbows work as direct water diverterrs to control water flow to various areas on the roof. These pieces also attach to the end of downspouts to move water away from the foundation or onto a splash block.
Endcaps seal the end of a gutter piece that isn't serving as an outlet to release water from the gutter. Endcaps also can be open-ended to connect two pieces of gutter together along extended lengths of roofing.
Unlike regular gutters, downspouts aren't open to collect rainwater. Downspouts attached to elbows at the corner of the home as completely sealed metal tubes running vertically down the corners of the home. These metal tubes container water for complete diversion away from the home's foundation. Downspouts come in length of 10 feet and require the attachment of an elbow joint at the bottom to divert flow away from the house.
The entire roof drainage system works well when fastened properly to the home. Brackets attach to the house siding to hold downspouts and elbow joints in place. Hangers can also be used to meet the specific needs based on house design. Under eave hangers and various brackets attach to the roofline to match exterior design and blend with the roofline of the home.
Water reaches a high speed when it's pouring down the length of a downspout. Splash blocks or plastic diverter hoses can be attached to the end of a downspout to prevent damage to the soil, garden or concrete area below a downspout. These pieces spread water gradually over the soil and limit erosion from water flow.
