Chimney Flashing Repair in Willow Glen, Campbell, CA

Chimneys are the most complex flashing detail on your roof — and the most common leak source we fix. Roof Leak Repair Masters is the local licensed expert for chimney flashing repair in Willow Glen, Campbell, CA. Historic homes here often have original clay tile or aging wood shake over tired underlayment.

Chimney flashing repair rebuilds the waterproof transition between your chimney and the roof. We remove failed step and counter flashing, inspect the cricket and masonry, install new metal properly regletted into mortar joints, and seal the crown — then water-test the whole assembly. Heritage street trees drop heavy debris, and the older housing stock means flashing details are frequently original.

Masonry Leaks vs. Flashing Leaks in Campbell

Here's what many roofers miss: water can enter through cracked chimney crowns, deteriorated mortar, or porous brick — and appear inside exactly like a flashing leak. Willow Glen is the charming San Jose neighborhood of tree-lined streets, with custom 1920s–30s homes in Tudor, Spanish Eclectic, and Craftsman styles. We inspect the masonry as part of every chimney diagnosis.

If the masonry is the culprit, we seal or rebuild the crown and tuckpoint bad joints — often alongside the flashing work, so the chimney is watertight from every angle.

• Porous brick wicks water inside
• We diagnose masonry + flashing together
• Crown cracks admit water into masonry
• Deteriorated mortar joints leak

Why Willow Glen Chimneys Leak More Than You'd Expect

Historic homes here often have original clay tile or aging wood shake over tired underlayment. Freeze-thaw cycles (where they occur), wind-driven rain, and decades of thermal movement all work mortar joints and flashing loose. Chimneys also concentrate roof runoff — a wide chimney without a cricket takes the full force of the upslope roof's water.

In Willow Glen we also see chimneys where the original flashing was installed to minimum standards decades ago and has simply reached end of life. Heritage street trees drop heavy debris, and the older housing stock means flashing details are frequently original.

• Wind-driven rain at the uphill face
• Thermal movement working joints loose
• Concentrated runoff at wide chimneys
• Original minimum-standard flashing aged out

The Four Parts of Chimney Flashing — and How Each Fails

Step flashing runs up the chimney sides, counter flashing is set into the mortar joints above it, apron flashing covers the downhill face, and a cricket diverts water around the uphill face. In Willow Glen we find counter flashing pulled from eroded mortar, missing crickets on wide chimneys, and aprons corroded through. Willow Glen is the charming San Jose neighborhood of tree-lined streets, with custom 1920s–30s homes in Tudor, Spanish Eclectic, and Craftsman styles.

Because these parts work as a system, patching one while another fails is wasted money. We assess and repair the full assembly.

• Missing cricket behind wide chimneys
• Corroded apron flashing
• Cracked crown letting water into masonry
• Step flashing separated from the chimney
