Why Roof Flashing Condition Matters for Your Home
Roof flashing plays a critical role in protecting your home from water intrusion. It seals the most vulnerable areas of your roof, places where roofing materials meet walls, chimneys, vents, and skylights.
In Baton Rouge, frequent rainstorms and high humidity make flashing failure especially risky. Even small cracks or lifted flashing can allow water to seep into insulation, framing, and drywall. When flashing problems are ignored, homeowners often face mold growth, rotting wood, and higher repair costs later.
Keeping flashing in good condition protects your roof’s lifespan, energy efficiency, and your home’s overall value.
What Roof Flashing Does
Roof flashing is a thin material, usually aluminum, galvanized steel, or copper, installed to direct water away from roof joints and penetrations.
Its main jobs include:
- Preventing water from entering seams and edges
- Protecting areas where roofing materials change direction
- Channeling water safely onto the roof surface and into gutters
Without properly installed flashing, even a new roof can develop leaks quickly, especially during storms common in Baton Rouge.
Chimney, Vent & Skylight Flashing Issues
Some roof areas are more prone to flashing failure than others:
Chimney Flashing Problems
Chimneys experience constant expansion and contraction. Over time, flashing can pull away, crack, or lose its sealant, allowing water behind the brick or siding.
Vent Pipe Flashing Damage
Rubber boots around vent pipes often crack due to sun exposure and heat. Once damaged, they allow rainwater to enter directly into the attic.
Skylight Flashing Failures
Improper skylight installation or aging flashing systems are common leak sources. Water stains often appear long before the leak is visible from outside.
In Baton Rouge’s wet climate, these issues worsen quickly without professional repair.
Signs Flashing Is Leaking
Water Stains on Ceilings or Walls
Brown stains near chimneys or vents often indicate flashing leaks rather than shingle failure.
Mold or Mildew in Attic Areas
Moisture from slow leaks creates ideal conditions for mold growth, especially in humid Louisiana weather.
Loose or Rusted Flashing
Visible rust, bent metal, or lifted flashing edges are clear warning signs.
Peeling Paint or Bubbling Drywall
Moisture trapped behind walls often shows up as peeling or bubbling interior finishes.
If you notice any of these signs, scheduling a roof inspection in Baton Rouge can prevent more serious damage.
Flashing Repair vs Replacement
Not every flashing issue requires full replacement. The right solution depends on the damage and the roof condition.
Roof Flashing Repair Is Often Enough When:
- Damage is minor or localized
- Sealant failure is the main issue
- Flashing material is still structurally sound
Flashing Replacement Is Better When:
- Flashing is severely corroded or cracked
- Leaks continue after previous repairs
- Flashing was improperly installed
At Brian M. LeBlanc Roofing, every job starts with a detailed inspection. If a simple repair solves the problem, we won’t recommend unnecessary replacements; building trust matters.
