Commercial Roof Maintenance & Repair

Most roof failures start small. A split seam, a clogged drain or a loose flashing can turn into leaks, wet insulation and early replacement if it's left alone. Our maintenance and repair services keep commercial and industrial roofs watertight, protect what's under them, and help you get the full service life out of your roofing investment.

​

Annual & Semi-Annual Maintenance Programs

Scheduled inspections are the most cost-effective way to protect a roof. On each visit our crews:

  • Inspect the membrane, seams, flashings, penetrations and roof-mounted equipment

  • Clear debris from drains, scuppers, gutters and downspouts

  • Make minor repairs on the spot before they become leaks

  • Check sheet metal, coping, counterflashing and sealants

  • Note ponding water, wear and any damage from other trades

  • Deliver a written report with photos and recommended next steps

Semi-annual programs usually include a fall visit before the rainy season and a spring visit to check for winter damage. Annual programs work well for newer roofs and buildings with lower exposure.

​

Leak Response & Roof Repairs

When a roof leaks, you need someone who will find the source, not just patch the stain. We trace the leak, fix the cause, and tell you clearly whether it was a one-time issue or a sign of a bigger problem. We repair all major low-slope systems, including built-up (BUR), modified bitumen, TPO, PVC, KEE and coated roofs.

​

Tenant Improvement & Penetration Work

New HVAC units, curbs, vents, conduit and other penetrations are among the most common sources of leaks. We install and flash new penetrations, seal abandoned ones, and restore the roof after other trades finish, so the system stays watertight and your warranty stays intact.

​

Portfolio & Multi-Property Maintenance

For property managers with multiple buildings, we can build an annual maintenance budget for the whole portfolio. You get consistent inspections, clear reporting on each roof, and a plan to prioritize repair, restoration or replacement over time.

​

Why Maintenance Matters in Southern California

Intense sun breaks down membranes and sealants over time. Santa Ana winds loosen flashings and blow debris into drains. Our dry months make it easy to forget the roof until the first storm. Routine maintenance catches these problems early, and many manufacturers require it to keep their warranty valid.

​

Know When It's Time for More Than a Repair

If repairs keep adding up, we'll tell you. Our roof surveys and life cycle evaluations give you a clear picture of how much life your roof has left. We'll recommend continued maintenance, restoration coatings or a re-roof, whichever makes the most sense for your building and budget.
