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

Why Chimney Flashing Fails
Chimney flashing in Allendale 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 Bergen County 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 Allendale homes?
Nine times out of ten it's the flashing, not the chimney itself. Freeze-thaw cycles in Bergen County 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 NJ winters.
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 Bergen County chimneys.
How do I know my chimney flashing has failed?
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 Allendale home warrants a look.
