Why Roof Overflow Drains are Essential

Roof drains with overflow provide an immediate backup (‘overflow’) drain next to the primary drain, which is an essential method of protecting any property from water damage.

The overflow is a secondary element of a roof drainage system, further ensuring the protection of your roof from compromise by rain and foul weather. Typically supporting a primary roof drain, the overflow drains otherwise work in the same fashion as their counterparts, providing more drainage over the target surface area. The added layer of defense justifies the investment immediately, by avoiding costly water damage.

Utilizing one of these drains provides a number of benefits; contact the experts at Thunderbird Products to learn more.
