Chimney Services in Mountainside, NJ

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

Why Chimney Flashing Fails

Chimney flashing in Mountainside homes fails for several predictable reasons:

1. Improper original installation — the most common cause, often using roofing cement instead of proper step flashing
2. Thermal movement — the chimney and roof expand/contract at different rates, breaking seals
3. Mortar deterioration — counter flashing embedded in failing mortar joints loosens
4. Ice damage — freeze-thaw cycles in {county} winters work flashing loose over time
5. 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.
