Why Chimney Flashing Fails
Chimney flashing in 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.

How does chimney flashing work?
Flashing is the layered metal seal where the chimney meets the roof — step flashing woven into the shingles plus counter-flashing set into the masonry. It fails from thermal movement, corrosion, and shortcut installs that rely on caulk instead of proper layering.
Do wide chimneys need special flashing?
A cricket is a small peaked diverter built behind the chimney that splits water flow around it. Building code calls for one on chimneys wider than 30 inches — without it, water and snow pile up behind the chimney and eventually find a way in.
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 Harlem home warrants a look.
Will insurance cover chimney flashing repair in Harlem?
If storm damage caused the failure — wind-lifted flashing, impact damage — coverage is common. Gradual corrosion typically isn't covered. We document the cause with photos and help Harlem homeowners with claims when weather is to blame.
