The chimney is one of the most vulnerable points on any Demarest 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 Demarest 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 is a chimney cricket and do I need one?
Chimneys over 30 inches wide should have a cricket — a mini-roof behind the chimney that diverts water around each side rather than letting it pool against the masonry. Many older Demarest homes are missing one.
Can you fix the top of my chimney?
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.
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 Demarest home warrants a look.
Is chimney leak damage covered by homeowners insurance?
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 Demarest homeowners with claims when weather is to blame.
