The chimney is one of the most vulnerable points on any East Harlem roof. Where the chimney meets the roof, improper flashing is the number one cause of roof leaks — and we see it constantly throughout Manhattan.

Why Chimney Flashing Fails
Chimney flashing in East Harlem homes fails for several predictable reasons:
- Improper original installation — the most common cause, often using roofing cement instead of proper step flashing
- Thermal movement — the chimney and roof expand/contract at different rates, breaking seals
- Mortar deterioration — counter flashing embedded in failing mortar joints loosens
- Ice damage — freeze-thaw cycles in New York City winters work flashing loose over time
- Missing cricket — chimneys wider than 30 inches need a cricket to divert water
Proper Chimney Flashing Installation
We install chimney flashing the right way — using individual step flashing pieces woven with each shingle course, counter flashing cut into mortar joints (not surface-mounted), and a proper cricket on wider chimneys. This multi-layer approach creates a watertight seal that moves with the structure instead of fighting it.

Why is my chimney leaking?
Nine times out of ten it's the flashing, not the chimney itself. Freeze-thaw cycles in New York City work the sealant and metal loose. Cracked crowns and missing caps cause the rest — we pinpoint the source first.
What is chimney flashing and why does it fail?
It's the two-layer metal system sealing the roof-to-masonry joint. Done right, it's mechanical — metal shedding water over metal. Done cheap with sealant, it starts leaking within a few NY winters.
Do you repair chimney crowns and caps?
We handle the full top-of-chimney system: crown repair or recasting, cap installation, and masonry repair where freeze-thaw has spalled the brick on East Harlem homes.
What are the signs of a chimney leak?
Ceiling stains near the fireplace, peeling paint on the chimney wall, or dampness in the attic around the chase. From outside: lifted flashing edges, rust, and cracked mortar joints. Any of these on your East Harlem home warrants a look.
