Reglet

For the reglet used in typesetting, see Reglet (typesetting).

A reglet is found on the exterior of a building along a masonry wall, chimney or parapet that meets the roof. It is a groove cut within a mortar joint that receives counter-flashing meant to cover surface flashing used to deflect water infiltration. Reglet can also refer to the counter-flashing itself when it is applied on the surface, known as "face reglet" or "reglet-flashing".

Reglet detail

Description

Reglet Groove

The reglet is created typically with a grinder or masonry cutting saw that cuts 3/4" to 1-1/2" deep into a mortar joint between two bricks.^[1] The counter-flashing is then inserted to the reglet and held in place with thin metal wedge covered with a sealant.

Face Reglet

A face reglet (also known as reglet-flashing) is counter-flashing that is typically made out of either copper or lead-coated copper.^[2] It is applied on the surface of the wall or parapet and screwed into place, with additional sealant placed between the surface and the counter-flashing.^[3] It is easily removable for roof repair and flashing replacements.

A face reglet can also be called a raggle^[4] and may be related to regle, a groove.
