What is Chimney Flashing?
Metal chimney flashing is vital for waterproofing. It surrounds your chimney’s base at the roof, sealing tightly to block rainwater.

REGULARLY CHECK FOR SIGNS OF RUST, CORROSION, OR SEPARATION IN THE FLASHING.

- Leak Prevention: Without flashing, rainwater can enter, causing interior water damage, rot, and mold growth.
- Expansion and Contraction: Accommodates natural movement of roofing materials due to temperature fluctuations. Flexibility prevents cracking and separation that could lead to leaks.
