Fixing Metal Roof Leaks Around Flashing in Battle Creek, MI
What Is Roof Flashing?
Flashing is a thin sheet of metal (often aluminum, galvanized steel, or copper) installed to direct water away from critical roof areas—especially where the roof intersects with vertical surfaces or penetrations. On a metal roof, flashing is a vital barrier that seals off seams and joints from water infiltration.
Flashing is typically installed:
- Around HVAC units and vent stacks
- At roof-to-wall junctions
- Along skylights and roof hatches
- At the base of chimneys or parapet walls
When properly installed, flashing works in harmony with your roof system. But when it fails, water can seep through the smallest openings, leading to internal moisture damage, insulation decay, and mold growth—especially problematic in large commercial structures.
What Causes Flashing to Fail on Metal Roofs?
Understanding what causes flashing failures can help you act before a minor issue becomes a major repair.
Improper Installation
Poor workmanship is a major reason flashing fails. If flashing is not integrated correctly into the roofing system—or if incompatible materials are used—it can pull away or crack under movement and thermal expansion. This often happens at roof penetrations where details are more complex.
Thermal Movement and Expansion
Metal expands and contracts with temperature changes, and if flashing is not installed with this in mind, it may warp, tear, or pull away from the roof structure over time. This movement leaves small gaps that water can easily penetrate.
Age and Corrosion
Even durable materials like metal degrade over time. Flashing may rust, crack, or break down due to prolonged exposure to the elements. Fasteners may loosen or sealants may dry out, both of which compromise watertightness.
Physical Damage or Lack of Maintenance
Rooftop foot traffic, debris, and weather events can all damage flashing. Without routine inspections and maintenance, small issues can go unnoticed until a leak becomes visible inside the building—at which point water may have already caused extensive internal damage.
Best Practices for Metal Roof Leak Repair Around Flashing
Addressing flashing-related leaks requires more than a patch job. Commercial property owners in Battle Creek, MI should follow a thorough and professional approach to ensure long-term protection.
Conduct a Detailed Roof Inspection
Don’t rely on assumptions. A thorough inspection should be the first step, focusing on all flashing components, especially at penetrations. Trained professionals can detect small gaps, uplifted metal, dried-out sealants, or loose fasteners that are easy to miss.
Remove and Replace Damaged Flashing
If flashing is rusted, punctured, or poorly installed, replacement is often the most reliable solution. This involves carefully removing the old flashing, installing new flashing with proper overlap and fastening, and sealing edges with commercial-grade sealant compatible with your roof material.
Use High-Quality Materials and Sealants
Quality materials matter. Whether it is metal flashing or the sealant used at joints, subpar products can lead to premature failure. Choose materials that match your existing roof and are designed to withstand Battle Creek’s seasonal temperature swings and precipitation patterns.
Schedule Preventive Maintenance
After the repair, schedule semi-annual roof inspections to catch early signs of wear or new damage. Regular maintenance allows you to preserve the effectiveness of flashing, extend your roof’s lifespan, and avoid emergency repairs that disrupt business operations.

FAQ
How do I know if flashing is the cause of my metal roof leak?
Look for signs like water stains near HVAC units, vents, or skylights. A professional inspection can confirm if deteriorated or loose flashing is to blame.
Can I repair flashing leaks myself?
DIY repairs are not recommended for commercial buildings. Improper handling can worsen the issue or violate warranty conditions. Always consult a professional contractor.
How often should flashing be inspected?
Inspect your flashing at least twice a year—typically in the spring and fall—and after major weather events.
Is replacing flashing expensive?
While not the costliest roof repair, replacing flashing should be budgeted properly. Costs vary depending on accessibility, extent of damage, and roof size.
Can flashing issues lead to mold or insulation damage?
Yes. Leaks around flashing can lead to trapped moisture, damaging insulation, ceiling tiles, and promoting mold growth—especially in commercial environments with complex HVAC systems.
