Commercial Roof Repair for All System Types
Water intrusion is the most destructive force acting on your commercial building. A single unaddressed leak can lead to mold growth, structural damage, damaged inventory, and costly interior repairs. Vanguard Roofing AZ responds quickly to minimize damage and get your roof watertight again.
We service all commercial roofing systems — spray polyurethane foam, TPO, EPDM, modified bitumen, built-up roofing (BUR), and metal roofs. Our technicians are experienced at diagnosing the true source of leaks, which is often not directly above where water appears inside the building.
- Emergency leak repair — fast response throughout Phoenix metro
- Storm and wind damage restoration
- Ponding water and drainage solutions
- Flashing and sealant repairs
- Insurance claim documentation and assistance
What We Fix
Repair Services We Provide
Emergency Leak Repair
When water is actively entering your building, every hour counts. Our team responds quickly to locate the source of the intrusion and make it watertight. We provide temporary remediation when needed to stop active damage, followed by a permanent repair once conditions allow.

- Permanent repair with documented root cause
Storm Damage Restoration
Arizona's monsoon season (June 15 – September 30) brings severe weather capable of damaging even well-maintained commercial roofs. High winds lift membranes and flashings, hail punctures single-ply systems, and torrential rain overwhelms drains. Our post-storm inspection and repair service gets your roof back to full performance.

- Comprehensive post-storm roof inspection
- Wind uplift and membrane repairs
- Hail damage assessment and repair
- Drain clearing and overflow protection
Ponding Water Solutions
Standing water on a flat commercial roof is a serious problem. Water that ponds for more than 48 hours accelerates membrane deterioration, adds structural load, and creates an environment for biological growth. We address ponding water through improved drainage, additional drains or scuppers, and using foam to build up low spots and redirect flow.
- Roof drainage assessment and redesign
- Additional roof drains and scuppers
- Foam fill to eliminate low spots and birdbaths
- Overflow drain installation for code compliance
Flashing & Sealant Repairs
The majority of commercial roof leaks originate at flashings — the transitions between the roofing membrane and vertical surfaces like parapet walls, HVAC curbs, pipes, and skylights. UV exposure, thermal cycling, and age cause sealants and flashings to crack and separate. We repair and re-flash all penetration types to restore watertight integrity.
- Parapet wall and curb flashing repair
- Pipe boot and penetration sealing
- HVAC curb and equipment flashing
- Edge metal and coping cap repair
Insurance & Prevention
Insurance Claims & Preventive Maintenance
We document storm damage for your insurance claim and help prevent future damage with structured maintenance programs.
Insurance Claim Assistance
Report storm damage to your insurer promptly. We document the damage with dated photographs and a written report, provide an itemized repair estimate you can share with your insurer, and meet your adjuster on the roof at your request. Your insurer decides coverage. We don’t negotiate claims or promise coverage; for disputes, talk to a licensed public adjuster or an attorney.
- Detailed photographic damage documentation
- Written damage reports you can share with your insurer
- Itemized repair estimates
- On-site adjuster meetings at your request
