Chimney & Roof Flashing Repair in Houston, TX
Over 80% of persistent roof leaks in Houston happen at vertical wall and chimney joints—not through the shingles themselves. Stop hidden water intrusion, decking rot, and ceiling stains with custom step, counter, and apron flashing installed by HAAG-certified roofers.
Why Roof Flashing Failures Are Houston’s Most Dangerous "Silent Leaks"
While wind-blown shingles produce immediate, obvious damage, compromised flashing acts as a slow, hidden gateway for rainwater during Houston's notorious tropical storms.
⚠️ The Silent Leak Reality: Flashing metal expands and contracts under Houston's brutal 100°F summer heat and sudden cold fronts. When caulking dries, nails back out, or rusted metal cracks, rainwater seeps behind siding and masonry into your attic rafters for months before a single drop stains your living room ceiling.
Chimney Base & Counter Flashing
Chimneys intersect the roof plane at right angles, catching massive water runoff. If the counter flashing isn’t properly reglet-cut into brick mortar joints, wind-driven rain penetrates straight behind the masonry facade.
Roof-to-Wall Transitions
Where two-story walls, dormers, or porch roofs meet an upper slope, overlapping step flashing pieces must be woven beneath each shingle row. Missing kick-out flashing diverts water directly inside exterior stucco or siding.
Decking & Framing Rot Prevention
Left unchecked, moisture from compromised flashing saturates plywood decking, rots wooden rafter tails, and breeds dangerous toxic mold in the attic. Discover our complete Houston roofing contractor services.
How HAAG Forensic Inspectors Assess Flashing Damage for Insurance Claims
Insurance adjusters frequently dismiss flashing leaks as "wear and tear." Here is how our certified forensic team proves storm causation.
Documenting Wind Uplift, Hail Impact & Sealant Ruptures
During severe Texas thunderstorms and hurricane-force gusts, high winds create negative pressure along the edges of chimneys and roof-wall junctions. This uplift bends thin sheet metal, pops mechanical fasteners, and tears the factory watertight seal between metal aprons and shingles.
Our HAAG-certified forensic roof inspectors meticulously photograph dent patterns on aluminum flashing, wind-lifted step metal, and storm-sheared counter flashing corners. We prepare engineering-grade damage reports that substantiate full replacement in your claim rather than cosmetic patches.

Frequently Asked Questions About Chimney & Roof Flashing
Clear answers on identifying, repairing, and preventing roof flashing leaks in Texas homes.
Common warning signs include water stains on ceilings or walls adjacent to a chimney or vertical exterior wall, damp drywall in the attic near roof transitions, peeling interior paint around a fireplace, rusted fireplace dampers, or visible gaps and cracked caulking where metal flashing meets masonry or siding.
Flashing leaks rarely cause an immediate gushing torrent inside living areas. Instead, small trickles of water enter behind siding, chimney brickwork, or step flashing courses with every rain. This moisture travels along rafters and insulation for months unnoticed, quietly rotting the roof decking, fascia, and structural framing before water stains finally break through finished drywall.
Minor flashing resealing and spot repairs in Houston generally cost between $250 and $550. Complete chimney re-flashing—including custom cutting a new reglet into brick mortar, fabricating step and counter flashing, and installing a cricket or saddle—typically ranges from $650 to $1,600 depending on chimney size, roof pitch, and access.
Yes. Severe Gulf storms, wind shear, and hail frequently dislodge counter flashing, tear metal joints, or puncture soft metal valleys. Our HAAG-certified forensic inspectors document storm-induced flashing displacements with high-resolution photo evidence to substantiate your insurance claim and ensure your carrier pays for complete water-tight restoration.
