When it comes to your roof system, it’s essential to have all components properly installed and sealed to guarantee it remains watertight. Chimney flashing is crucial to ensure no water can enter your home, but if damage occurs and causes leaks, it can result in costly structural issues if not addressed promptly. Knowing what to look for can help you identify a problem before it turns into a major repair.

What Is Chimney Flashing

Chimney flashing is a metal barrier, usually made of aluminum or galvanized steel, that seals the gap between the chimney and the roof. Flashing will also be installed where the roof meets the wall, around vents, or skylights. Its purpose is to redirect water away from this vulnerable joint toward the gutters. When flashing is damaged or worn, water can seep into your roof and interior walls.

Common Causes of Flashing Leaks

Leaks can happen for several reasons. Over time, weather and age can weaken the chimney flashing, causing it to rust, crack, or lift. Flashing that wasn’t installed properly may separate or allow gaps to form. Storms, debris, or shifting roof materials can also cause flashing to become displaced. Cracks in the mortar surrounding the chimney can lead to water getting behind the flashing as well.

Signs Your Chimney Flashing Is Leaking

These signs often indicate water is entering where the chimney meets the roof. Watch for these indications if you suspect a flashing issue:

• Water stains on ceilings or walls near the chimney
• Peeling paint or wallpaper inside your home
• Dampness in the attic around the chimney area
• Visible rust or gaps in the flashing
• Moss or algae growth at the chimney base

How to Inspect Chimney Flashing

Start with a visual inspection from the ground. Look for any signs of lifting, warping, or separation at the base of the chimney. If it’s safe to do so, a closer look from a ladder can reveal cracked sealant, rusted metal, or broken shingles nearby. Avoid walking on the roof unless you’re experienced and the conditions are safe. However, it’s recommended to schedule a roof inspection with a licensed roofing contractor.

What to Do If You Find a Roof Leak

If you confirm or even suspect a leak, you should act quickly. Place a container under any interior drips and move valuables away from affected areas. Take photos of the damage for insurance purposes and contact a roofing professional to assess the condition of your flashing and surrounding roof. Repair options may include resealing joints, replacing sections of flashing, or addressing damage to nearby roofing or chimney components.

Preventing Chimney Flashing Leaks

Flashing plays a critical role in preventing roof leaks, and regular maintenance is important to keep it in good condition. Schedule annual inspections with a professional roofing contractor, especially after severe weather. Check the chimney area from the ground for early signs of wear, and keep gutters clean to prevent water buildup that can lead to flashing failure. Be sure to clear roof and gutter debris as needed, particularly during heavy leaf accumulation in the fall.
