Chimney Leak & Flashing Repair

A leaking chimney is one of the most common causes of roof and interior water damage for Long Island homeowners.
Water can enter through damaged flashing, cracks in brick or mortar, deteriorated crowns, or gaps around the flue. If ignored, chimney leaks can cause mold, ceiling stains, rot, rust, and structural damage.

Village Chimney provides licensed and insured chimney leak detection and flashing repair across Suffolk County, with over 27 years of experience solving chimney and roofline water issues.

We diagnose the leak, stop the water intrusion, and protect your home from long-term damage.

Common Causes of Chimney Leaks

Most chimney leaks occur due to one of these issues:

1. Damaged or Improper Flashing

Flashing is the metal barrier that seals the joint between the roof and chimney.
If flashing is:

rusted
cracked
loose
improperly installed
unsealed

…it can allow water to flow directly into your attic or walls.

2. Cracked Chimney Crown

The cement top of the chimney can crack from freeze-thaw cycles.
Once water enters, the damage spreads quickly.

3. Missing or Damaged Chimney Cap

Without a cap, rain and snow fall directly into the flue, causing rust, odors, and internal damage.

4. Mortar Joint Deterioration

Mortar breaks down naturally over time, especially with coastal humidity and storms.

5. Porous Brick & Masonry Absorption

Older chimneys absorb water like a sponge.
Waterproofing is essential.

How We Fix Chimney Leaks

We perform full chimney-to-roof leak diagnostics, then provide the correct repair based on the problem:

✔ Flashing Repair & Replacement

Step flashing installed under shingles
Counter flashing embedded into mortar joints
Waterproof sealant applied to all seams
Stainless steel or aluminum options

Proper flashing repair is the #1 solution for chimney leaks.

✔ Chimney Repointing (Mortar Repair)

Loose or cracked mortar joints are ground out and replaced with fresh, matched mortar to prevent further water entry.

✔ Crown Repair & Rebuilding

A cracked crown allows water to seep into the chimney walls.
We repair or rebuild the crown with long-lasting, weather-resistant materials.

✔ Chimney Cap Installation

A stainless steel cap prevents direct rain entry, animal nests, and moisture damage.

✔ Chimney Waterproofing

We apply a professional-grade breathable masonry sealer that prevents water absorption without trapping moisture.

Signs Your Chimney Is Leaking

Call for service if you notice:

Water stains on ceilings or walls
Damp or musty odors near the fireplace
Drips inside the firebox
Rust on the damper or firebox
Bubbling or peeling paint
Mold or mildew around the chimney
Shingles lifting near the chimney
Soft or rotted wood in the attic

Leaks often start small — catching them early saves thousands in repairs.

Why Chimney Leaks Are So Common on Long Island

Suffolk County’s weather is tough on chimneys:

Salt air
Coastal humidity
Heavy rainstorms
Strong winds
Freeze-thaw cycles
Older home construction

This environment accelerates masonry deterioration and flashing corrosion, making regular maintenance essential.
