Chimney flashing is a critical but often overlooked component of your chimney system. It seals the gap between your chimney and roof, protecting your home from costly water damage. Properly installed chimney flashing can last 30 or more years, depending on the quality of materials used. But once your chimney flashing starts to deteriorate, it leaves your home vulnerable to leaks and structural issues. If you see any of these signs, it's time to replace your chimney flashing.
1. Water Stains or Leaks Inside Your Home
A water stain on the ceiling or wall near your chimney is a telltale sign that your flashing might have failed. Any water coming through the damaged flashing can lead to mold growth, wood rot, and other costly repairs.
2. Visible Rust or Corrosion
When metal chimney flashing shows signs of rust or corrosion, it can no longer provide a watertight seal, making your home susceptible to leaks.
3. Cracks in the Flashing
New England’s harsh weather conditions and temperature fluctuations can make aluminum or galvanized steel flashing crack over time, breaking the water-tight seal.
4. Detached Flashing
Strong winds or improper installation can cause chimney flashing to pull away from your roof or chimney. These gaps need to be addressed immediately to prevent further damage.
5. Older Homes
Even if there are no visible issues, older flashing may lack the strength to withstand New Hampshire’s challenging weather conditions, putting your roof, chimney, and home at risk.
6. Dried or Deteriorated Sealant
The sealant that secures the flashing can dry out or deteriorate over time, leaving it loose and ineffective.
Why Timely Replacement Matters
Damaged flashing allows water to weaken your roof, damage your home, and encourage mold growth. If your chimney flashing is showing signs of trouble, it’s important to replace now it to avoid costly repairs down the road.
