Sizing a roof water drain.
The next step is to determine each roof area that will be served by a separate leader drain pipe scupper or downspout.
Downspouts are drainage pipes that direct rain water from the roof to the ground.
Water collected by a rain gutter is fed usually via a downpipe also called a leader or conductor from the roof edge to the base of the building where it is either discharged or collected.
Downspouts are most commonly seen attached to the corners of home or building.
The first step in sizing a roof drain is to calculate the surface area of the roof that the drains will be covering as well as the average hourly rainfall rate at the building location.
This is where the rainwater is lead away from the building s foundation so that no rainwater is able to pool around the building.
Downpipe fittings and connectors are used to join sections of downpipe together or to connect them to other parts of the guttering system they form waterproof and durable seals ensuring that rainwater is effectively drained away.
