// What We Repair

Common Commercial Roof Problems We Fix

Most commercial roof leaks start small and in predictable places. Catching them early keeps water out of insulation, ceilings, electrical, and inventory — and keeps repair costs a fraction of replacement.

Leaks

Active Roof Leaks

We trace water back to where it actually enters the roof — which is often feet away from where it drips inside.

Membrane

Cracks, Splits & Blisters

Daily heat cycling breaks down flat roof membranes over time. We repair cracked, split, and blistered areas with compatible materials.

Edges

Flashing Separation

Flashing at walls, parapets, and roof edges pulls loose and lets water behind the membrane. We re-secure and re-seal it.

Drainage

Ponding Water

Clogged drains and low spots hold water that degrades the roof. We clear and correct drainage problems before they become leaks.

Penetrations

Pipes, Vents & HVAC Curbs

Penetrations and HVAC curbs are top leak points when sealants and flashing fail. We rebuild the seal around them.

Metal

Seam & Fastener Failure

On metal roofs, separated seams and backed-out fasteners let water in. We re-fasten, seal, and secure the panels.

// How We Work

Our Commercial Roof Repair Process

Patching where it drips is how leaks come back next rainy season. Our process is built to find the cause, not just the symptom.

STEP 01

Roof Inspection

We walk the full roof — membrane, seams, flashing, drains, and penetrations — not just the area above the leak.

STEP 02

Photo Report

You get photos of what we found and a clear explanation of what's causing the problem, in plain language.

STEP 03

Honest Options

A written estimate for the repair — and if coating or replacement is the better long-term value, we'll show you that too.

STEP 04

Repair & Document

We complete the repair with materials compatible with your roof system and document the finished work.

Repair, Restore, or Replace?

Not every leaking roof needs to be replaced — and not every roof should keep getting patched. Here's how we help building owners decide.

Repair

Targeted Roof Repair

Usually the right call when:

  • Damage is isolated to one or a few areas
  • Insulation underneath is still dry
  • The membrane is structurally sound overall
  • The roof is generally under about 20 years old
Restore

Roof Coating Restoration

Worth a look when:

  • The roof leaks in different spots every season
  • The surface is weathered but the roof deck is sound
  • You want to extend roof life without a tear-off
  • You want a reflective cool roof surface
Roof coatings & restoration →
Replace

Roof Replacement

Typically needed when:

  • Insulation is widely saturated
  • The deck or structure is damaged
  • The roof has failed across most of its surface
  • Repairs would cost more than they're worth

Why Building Owners Call Us for Roof Repair

Experience

30+ Years, Commercial Only

We've worked strictly on commercial roofs since 1992 — warehouses, offices, retail centers, apartments, churches, hospitals, and more.

Transparency

Photo-Documented Work

You see what we see. Every inspection and repair comes with photos so you know exactly what was found and fixed.

Honesty

Solutions, Not Upsells

If a repair will do the job, we repair it. If coating or replacement saves you money long-term, we'll explain why.

★★★★★

"I have tried other vendors in the past and usually get left with areas that need future repairs. The few times I have had Central Roofing out for repairs and maintenance the roof always seems to be in better operating condition than prior to the repairs."

// Questions

Commercial Roof Repair FAQs

How much does commercial roof repair cost?

It depends on the roof type, how much damage there is, and how hard the area is to access. Targeted repairs typically cost a small fraction of a full replacement. We inspect the roof and give you a free, written estimate before any work begins.

Can a flat roof leak be repaired without replacing the roof?

Often, yes. When damage is caught early and limited to specific areas — and the insulation underneath is still dry — a targeted repair can solve the problem without replacement.

How do you find where a flat roof is leaking?

We inspect the full roof surface, seams, flashing, drains, and penetrations. Water often travels under the membrane before it shows up inside, so the leak source can be some distance from the drip.

When should I coat or replace instead of repair?

If the roof leaks in new spots every season or the surface is broadly worn out, repeated repairs stop being good value. A roof coating restoration can often seal the whole surface and extend roof life without a tear-off; widespread wet insulation or deck damage usually means replacement.

What types of commercial roofs do you repair?

TPO and other single-ply membranes, modified bitumen, built-up roofing (BUR), silicone- and acrylic-coated roofs, and metal roofs on flat and low-slope commercial buildings.

Do you offer emergency roof repair?

Yes. For active leaks and storm damage, call 310-527-6770 or see our 24/7 emergency roof repair service.

How can I prevent future roof leaks?

Regular inspections catch small problems before they turn into leaks. Our commercial roof maintenance programs keep drains clear, seal weak points, and extend roof life.
