 <li><span class="recommended">New and existing buildings should incorporate ''overflows'' to handle large rain events</span>. The primary function of an ''overflow'' is to keep a roof from collapsing when ''primary roof drains'' are plugged or cannot drain heavy rainfall. Where no ''overflows'' are specified, the building structure should be designed to carry the total load of water collected on the roof, in the event of ''primary roof drain'' failure (refer to the ''British Columbia Building Code'').
