Abstract

The roof drainage system is an important aspect of the overall roof design. This is particularly the case for parapet and valley gutters which are inside the building line and are effectively part of the roof where any overflow into the building would be unacceptable. Eaves gutters are normally positioned outside the building where occasional overflow would not be harmful. Eaves guttering is generally fixed to the fascia or rafters of the building. Most eaves gutters are laid level or nominally level (1mm - 3mm fall). Any falls should be laid in the direction of the outlets which discharge rainwater via downpipes to surface or underground drainage points.
