What Is a Roof Flashing for a chimney?Roof flashing lead based

Chimney flue flashing is a specialized form of roof flashing designed to create a watertight seal around the base of your chimney flue. Its primary purpose is to prevent water from infiltrating your home through the vulnerable area where the chimney structure intersects with your roof.

The Importance of Chimney Flue Flashing

Properly installed chimney flue flashing serves several critical purposes:

1. Waterproof Barrier

Chimney flue flashing acts as a waterproof barrier, ensuring that rainwater and melted snow are directed away from the chimney's base. This prevents costly water damage to your home's interior.

2. Structural Integrity

By preventing water from seeping into the roof structure around the chimney, flashing helps maintain the structural integrity of your roof. It reduces the risk of rot, mold, and damage to the underlying materials.

3. Energy Efficiency

Leaky chimney flue flashing can lead to heat loss during the winter and increased cooling costs during the summer. Proper flashing helps maintain your home's energy efficiency by keeping it watertight and insulated.

Types of Roof Flashing

Years ago, almost all flashings were made from lead sheet. Lead is a soft, easily worked metal, which can be easily moulded to various shapes without cracking or splitting.

Now, due to cost, and because of concern about lead contamination, materials such as zinc sheet, rubber, plastic, and even waterproofed impregnated paper, are also used. Where lead is used, it is often painted with a waterproof paint.

Rubber Aluminium flashings for flatter tilesRubber aluminium flashing

Aluminium square (ideal for flatter tiles such as slate but not so good for less flat tiles as the aluminium does not "mould" to surfaces so well). A Storm collar is not required with these flashings but can be used to hide the rubber. 

 

EPDM flashings for non-tiled roofsRoof flashing for metal roof

The multi-application flashing in a highly durable EPDM, edged with a flexible aluminium band, flashes hot or cold flues and pipes on metal roofs. The square base fits any prepared hole on most roof profiles.

 

Signs of Chimney Flue Flashing Issues

To ensure your chimney flue flashing is doing its job effectively, watch out for these signs of potential issues:

  • Water Stains: Water stains on your ceilings or walls near the chimney may indicate a flashing problem.
  • Mold and Mildew: Excessive moisture due to flashing issues can lead to mold growth.
  • Deterioration: Flashing problems can cause the surrounding roofing materials to deteriorate prematurely.

Maintenance and Repairs

Regular maintenance and prompt repairs are essential to keep your chimney flue flashing in top condition. If you notice any issues, it's crucial to address them promptly to prevent further damage.
