Chimney flashing is a crucial aspect of roofing that ensures the watertight seal between the chimney and the roof. It prevents water from seeping into the roof structure, which can lead to costly repairs and potential structural damage.
Properly flashing a chimney involves installing metal or pre-formed rubber sheets around the base of the chimney and extending them up the sides to create a watertight barrier. This flashing diverts water away from the chimney and into the gutter system.
