Commercial
Roof Repair Services in Tucson, Arizona

Business roofs demand immediate attention when problems develop. Water intrusion threatens inventory, equipment, and operations. Bob’s Custom Roofing provides fast, effective commercial roof repair throughout Tucson, addressing emergencies and planned maintenance needs for retail, office, industrial, and property management clients. With 53 years of experience, we diagnose problems accurately and execute repairs that solve issues permanently.

Commercial repair differs from residential work fundamentally. Larger roof areas complicate leak location. Business operations cannot tolerate extended disruptions. Tenant relationships require professional conduct and clear communication. We understand these pressures and deliver repair services that minimize business impact while restoring roof protection.

Emergency Commercial Roof Repair Response

Water intrusion creates urgent business problems. Damaged inventory, disrupted operations, and potential liability demand immediate professional response. Our emergency repair services address critical situations during business hours Monday through Friday, prioritizing cases where active leaks threaten operations.

 

Emergency situations we handle:

 

  • Active leaks threatening inventory or equipment
  • Storm damage is exposing building interiors
  • Equipment malfunction is damaging the roof membranes
  • Vandalism or impact damage requiring immediate attention
  • Drain blockages are causing water accumulation
  • Flashing failures during monsoon events

 

Emergency response focuses on stopping water intrusion quickly. Temporary repairs provide immediate protection while permanent solutions are planned and scheduled appropriately. We never rush permanent work under emergency pressure, recognizing that hasty repairs often fail, requiring repeated service calls and mounting frustration.

Leak Detection for Commercial Buildings

Locating leak sources in commercial buildings is a challenge even for experienced contractors. Water travels along structural members, through wall cavities, and across large roof areas before appearing inside. Accurate detection requires systematic investigation and commercial building expertise.


Our leak detection process combines visual inspection from the roof and interior, water testing when sources remain unclear, infrared moisture scanning for hidden problems, and systematic elimination to identify actual entry points. This thorough approach finds problems other contractors miss, preventing the repeated service calls that waste money and erode confidence.


Commercial buildings hide leaks effectively. Drop ceilings, insulated roof assemblies, and large open spaces between the roof and occupied areas allow water to travel far from entry points. Interior damage locations rarely indicate actual leak sources. We trace water paths systematically rather than guessing based on interior evidence.

Can’t find the leak source? Call us for expert detection.

Systematic Repair Approaches

Effective commercial repairs address root causes rather than symptoms. Surface patches on membranes fail repeatedly when underlying problems go unaddressed. We execute repairs, solving actual issues, not just visible damage.

Membrane Repair Methods:

  • Hot asphalt patching for built-up roofing systems
  • Torch-applied patches on modified bitumen
  • Heat-welded repairs on thermoplastic membranes
  • Properly sized patches extending beyond damaged areas
  • Multi-layer repairs matching the original system construction
  • Primer and adhesive application, ensuring secure bonding

Flashing Restoration Techniques:

  • Complete flashing replacement when deterioration is extensive
  • Mechanical attachment restoration on loose components
  • Sealant renewal using commercial-grade products
  • Counterflashing installation preventing water intrusion
  • Equipment curb rebuilding when wood deterioration occurs
  • Metal work fabrication for custom flashing needs

Professional repair execution. Get service

Drainage System Repairs:

  • Complete drain replacement, including clamping rings
  • Scupper reconstruction and flashing integration
  • Slope correction using tapered insulation systems
  • Debris removal and preventive screening installation
