Specialized flashing repair for commercial flat roofs, parapet walls, equipment curbs, and transitions—protecting your building investment with expert installation and materials.
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 walls require multi-component flashing systems including base flashing, cant strips, coping, and counterflashing to prevent water infiltration at roof perimeters.
Rooftop HVAC units sit on raised curbs requiring proper curb flashing and pitch pans to create watertight seals around equipment penetrations.
Roof hatches and access points create large penetrations requiring careful flashing to maintain waterproofing while allowing regular access.
Roof drains and scuppers must be properly flashed to membrane systems while maintaining drainage capacity and preventing clogging.
Multiple pipes, vents, and conduits penetrate commercial roofs requiring individualized flashing approaches for each penetration type and size.
Building expansion joints require flexible flashing systems that accommodate structural movement while maintaining waterproofing integrity.
Heat-welded TPO membrane flashing terminations and detail work for seamless integration
Adhesive and tape-applied EPDM flashing with proper lap seams and penetration boots
Heat-welded PVC membrane flashing with factory-fabricated components when available

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.
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.
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.
Coastal winds create uplift forces at roof edges and penetrations. Improperly secured flashing becomes vulnerable during thunderstorms and tropical systems.
Commercial HVAC units run constantly in Georgia summers. Vibration stresses curb flashing connections, creating leak paths if not properly isolated.
Regular flashing inspections and minor repairs prevent major problems:
Catching separated flashing or loose sealant during routine inspection
If left unaddressed
Full flashing replacement plus interior damage: ceiling tiles, insulation, electronics, inventory loss, business interruption
Spring & Fall inspections for Georgia commercial buildings
Post-hurricane/tropical storm damage assessment
