Commercial Roof Flashing Repair

Specialized flashing repair for commercial flat roofs, parapet walls, equipment curbs, and transitions—protecting your building investment with expert installation and materials.

Commercial Flat Roof Flashing Challenges

Commercial buildings present unique flashing requirements due to flat roof designs, HVAC equipment installations, and building-specific transitions. Proper flashing at these critical points prevents the most common commercial roof leak sources.

Parapet Wall Flashing

Parapet walls require multi-component flashing systems including base flashing, cant strips, coping, and counterflashing to prevent water infiltration at roof perimeters.

  • Base flashing integration with membrane
  • Metal coping and counterflashing installation
  • Proper termination above waterproofing

HVAC Equipment Curbs

Rooftop HVAC units sit on raised curbs requiring proper curb flashing and pitch pans to create watertight seals around equipment penetrations.

  • Curb flashing with membrane overlap
  • Equipment vibration considerations
  • Proper drainage around equipment

Roof Hatch & Access Flashing

Roof hatches and access points create large penetrations requiring careful flashing to maintain waterproofing while allowing regular access.

  • Hatch curb flashing systems
  • Access-resistant flashing details
  • Traffic-rated flashing materials

Scupper & Drain Flashing

Roof drains and scuppers must be properly flashed to membrane systems while maintaining drainage capacity and preventing clogging.

  • Drain flange integration
  • Scupper box flashing
  • Emergency overflow provisions

Pipe & Conduit Penetrations

Multiple pipes, vents, and conduits penetrate commercial roofs requiring individualized flashing approaches for each penetration type and size.

  • Pipe boot and compression fittings
  • Pitch pans for irregular penetrations
  • Grouped penetration flashing

Expansion Joint Flashing

Building expansion joints require flexible flashing systems that accommodate structural movement while maintaining waterproofing integrity.

  • Flexible expansion joint covers
  • Movement-tolerant details
  • Membrane transitions

Protecting Your Georgia Commercial Investment

Flashing failures account for 70-80% of commercial roof leaks in Georgia. Understanding the risks and maintenance requirements helps property owners protect buildings, tenants, inventory, and avoid costly emergency repairs.

Why Commercial Flashing Fails Faster in Georgia

Thermal Cycling

Summer roof temps reach 150-170°F during day, dropping 40-50°F overnight. This daily expansion/contraction loosens fasteners and breaks sealant bonds faster than northern climates.

Ponding Water

Savannah's heavy rainfall (45-50" annually) combined with flat roof designs creates ponding. Standing water accelerates flashing deterioration, especially around equipment curbs and parapet walls.

Wind Uplift

Coastal winds create uplift forces at roof edges and penetrations. Improperly secured flashing becomes vulnerable during thunderstorms and tropical systems.

HVAC Vibration

Commercial HVAC units run constantly in Georgia summers. Vibration stresses curb flashing connections, creating leak paths if not properly isolated.

Preventive Maintenance Saves Money

Regular flashing inspections and minor repairs prevent major problems:

Preventive Repair

$300-$800

Catching separated flashing or loose sealant during routine inspection

If left unaddressed

Emergency Leak Repair

$3,000-$10,000+

Full flashing replacement plus interior damage: ceiling tiles, insulation, electronics, inventory loss, business interruption

+ Lost revenue during repairs
