Why Chimney Flashing Fails
Chimney flashing in Astoria 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.

What causes chimney leaks in Astoria homes?
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.
How does chimney flashing work?
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.
What is a chimney cricket and do I need one?
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.
Do you repair chimney crowns and caps?
Yes — we repair and rebuild cracked crowns, install stainless caps to keep water and animals out, and address spalling brick at the roofline. Crown cracks are a major hidden water entry point on New York City chimneys.
