Roof flashing is the unsung hero of your roofing system—thin strips of metal or waterproof material installed at critical roof transitions to direct water away from vulnerable areas. While your primary roofing material provides the main waterproof barrier, flashing protects the intersections, penetrations, and edges where two surfaces meet.
When flashing fails, water finds its way into these vulnerable spots, causing leaks that can damage roof decking, insulation, ceilings, walls, and building interiors. Properly installed and maintained flashing is essential for long-term roof performance and leak prevention.
Years of exposure to sun, rain, wind, and temperature changes cause metal to corrode, sealants to dry out, and material bonds to weaken.
Improper flashing installation—wrong materials, inadequate overlap, missing sealant, or incorrect fastening—creates immediate or future leak risks.
Metal flashing expands and contracts with temperature changes, potentially loosening fasteners, breaking sealant bonds, and creating gaps.
High winds can lift flashing edges, hail can dent or puncture metal, and debris impact can displace or damage flashing systems.
In Coastal Georgia's humid climate, uncoated steel flashing rusts, galvanized coatings fail, and even aluminum can corrode when in contact with incompatible materials.
HVAC technicians, satellite installers, or others walking on roofs can step on flashing, dislodge it, or damage sealant—often unknowingly.
When roofing is replaced without replacing flashing, old compromised flashing creates immediate leak risks under new roofing materials.
Building settlement or chimney separation can pull flashing away from surfaces, breaking the waterproof seal at critical connections.
Counter-flashing, step flashing, and cricket flashing around chimneys are frequent leak sources requiring specialized repair techniques.
Where roofs meet vertical walls, parapet walls, or dormers, flashing must properly integrate with siding or masonry to prevent leaks.
Skylight installations require head, side, and sill flashing that properly integrates with roofing and prevents water intrusion.
Plumbing vents, exhaust pipes, and other roof penetrations use boot-style flashing that can crack, tear, or separate over time.
Roof valleys channel large water volumes and require durable valley flashing that can fail from debris accumulation or corrosion.
Edge flashing and drip edges protect roof perimeters and fascia from water infiltration but can pull away or corrode.
Not all damaged flashing requires complete replacement. Understanding when repair is sufficient versus when replacement is necessary helps you make cost-effective decisions.
Minor Sealant Failure
Resealing edges and joints with quality caulk when metal remains sound
Loose Fasteners
Resecuring flashing with new fasteners and proper sealant application
Small Punctures or Tears
Patching localized damage with compatible materials when overall condition is good
Surface Rust Only
Treating early rust, applying rust inhibitor, and protective coating when metal integrity intact
Recent Installation Issues
Correcting improper installation details without full replacement when caught early
Extensive Corrosion
Rust-through, holes, or severely degraded metal that compromises structural integrity
Complete Separation
Flashing pulled away from surfaces or completely detached from roof structure
Age & Brittleness
Old flashing that cracks when touched or shows multiple failure points
During Roof Replacement
Flashing should always be replaced when installing new roofing for optimal performance
Wrong Material or Design
Improper flashing type, incompatible materials, or inadequate design for the application
We examine all flashing points, identify failure causes, assess material condition, and determine whether repair or replacement is appropriate for each area.
We specify appropriate flashing materials—copper, aluminum, galvanized steel, or coated metals—based on your roof type, climate conditions, and budget.
Following manufacturer specifications and building codes, we install flashing with correct overlap, fastening patterns, and sealant application to ensure watertight performance.
We ensure flashing integrates properly with roofing materials, wall surfaces, and adjacent components, then test water flow and drainage patterns.
You receive warranty coverage on both materials and workmanship, along with documentation for your property records.
Flashing Location & Accessibility
Chimney work is more complex than simple pipe boots. Steep roofs or difficult access increase labor costs.
Material Selection
Copper flashing costs more than aluminum or galvanized steel but offers superior longevity and corrosion resistance.
Extent of Damage
Simple resealing is less expensive than complete flashing replacement or addressing water-damaged roof decking.
Additional Repairs Needed
Flashing leaks often cause shingle damage, decking deterioration, or fascia rot requiring additional repair.
Minor Flashing Repair
$200-500
Resealing, minor adjustments, single pipe boot replacement
Moderate Repair/Replacement
$500-1,500
Multiple flashing points, partial valley replacement, wall flashing
Chimney Flashing
$800-2,500+
Complete chimney flashing system with step, counter, and cricket flashing
Prices vary based on specific conditions. Request a detailed inspection and estimate for accurate pricing.
While flashing repair represents an upfront investment, delayed repairs multiply costs exponentially. A $500 flashing repair can prevent $5,000+ in water damage to insulation, drywall, framing, and interiors.
Flashing leaks don't improve with time—they worsen steadily, causing progressive damage that becomes increasingly expensive to address. Early intervention protects your property and your budget.
Not all flashing materials perform equally in Savannah's humid, salt-air environment. Choosing the right materials for your roof type and location determines how long repairs last and how well they protect your property.
Zinc-coated steel offering decent corrosion resistance. Most common and economical flashing material for residential applications.
Lightweight, corrosion-resistant, and ideal for Savannah's salt-air environment. Our top recommendation for coastal properties.
Premium material offering unmatched longevity and distinctive appearance. Develops protective green patina over time.
For pipe penetrations, skylight flashing, and other applications requiring flexible seals, we use high-quality EPDM rubber boots and flexible flashing membranes designed for Georgia's UV exposure and temperature extremes.
We don't use one-size-fits-all flashing. Every repair considers:
