Detect and Repair Roof Leaks With Expert Commercial Roof Leak Detection Services in New Orleans

The entry point, not the ceiling tile. Water is followed from the stain back across the deck to where it gets in, marked on a roof plan and photographed before anyone repairs it.

Commercial leak detection

On a flat roof, water does not drop straight through. It runs along the deck, collects at a low point and finds a gap there, so the stain and the source can be a long way apart. Leak detection closes that distance.

Big Easy Roofing Company traces leaks on warehouses, shopping centers, offices and restaurants across New Orleans. We start inside at the stain, read the deck and the roof layout above it, and walk the likely path until the opening is found.

Once it is found and photographed, the fix is priced as a commercial roof repair, so you pay once for the right spot.

Path Traced, Not Assumed

From the interior mark, along the slope and the deck, to the opening that feeds it.

Pinned on a Roof Plan

The entry point is marked on a sketch of the roof, so maintenance staff can find it again.

Traced Around Your Day

Interior checks are booked for times when tenants and customers are not in the way.

Six Signs of a Leak
in a Commercial Roof

Commercial leaks tend to show indoors as small, scattered signs well before a ceiling gives way. These are the common ones.

Water-stained ceiling above a pendant light in a room corner

Stained Ceiling Tiles

A brown ring on a drop ceiling tile is the classic sign. Swapping the tile hides it without stopping it.

Water dripping off a roof edge against a dark sky

Drips Only in Heavy Rain

A leak that runs in a downpour but not a drizzle often points to wind-driven water at a parapet or a curb.

Air conditioning condensers mounted on the wall of a warehouse

Water Near Mechanical Lines

Line sets and condensate pipes pass through walls and roofs. Where they enter, sealant fails and water follows the pipe in.

Aged building with a rusted corrugated roof

Rust on Deck or Joists

Orange streaks on steel decking seen from inside show a slow leak that has been running for months.

Long weathered low-slope roof seen from above

Standing Water Up Top

Ponding sits on seams far longer than the rest of the roof. The joint under the water is where it usually gets through.

Two rooftop ventilation housings under a dark sky

Musty Air in Upper Rooms

Wet insulation above a ceiling smells before it stains. Offices right under the roof notice it first.

Where commercial leaks start

Four Places Flat
Roofs Let Water In

Across a large membrane, water nearly always gets in at one of four places.

Source 01

Curbs and Penetrations

Units, ducts, pipes and hatches all break the membrane. Their flashings dry out and split long before the field does.

UnitsPipe bootsTop culprit

Drains and Scuppers

A blocked drain backs water up over seams that were never meant to sit underwater.

Seams and Laps

Welds, tapes and torched laps open with heat, age and movement across a wide roof.

Parapet Walls and Coping

Cracked coping and loose wall flashing let wind-driven rain in behind the membrane at the edge.

One Stain, Two Openings

On a large roof it happens often. If the trace finds more than one entry point feeding the same area, each is shown and priced on its own.

Pricing the fix

What Decides the Cost
of a Commercial Leak Repair

The trace itself is free. The repair price rests on what turns up along the way.

How Much Insulation Is Wet

A fresh leak may have soaked a few boards. A long-running one can wet a whole bay.

What Failed

A cracked pipe boot is a short job. Rebuilding a unit curb or a parapet flashing takes longer.

The Roof System

Single-ply, modified bitumen and built-up each need their own repair materials and methods.

Roof Size and Access

Big roofs and awkward access add setup and carrying time.

Several Openings Found

Each separate opening is priced on its own line, so you can see what each one costs.

The opening is shown to you, with its price, before any work starts. Prefer to send the details in writing? The contact page takes them.

Two ways to handle a leak call

Chasing the Stain vs
Tracing the Source

Most leak calls go one of two ways. On a commercial roof the second way is usually cheaper by the second visit.

Commercial Roof Leak Questions

Keep a note of which storms bring the leak on. It shortens the trace.

Talk to a roofer504-229-3955

On a low-slope roof water runs along the deck and the insulation until it reaches a gap or a low point. On a large building that can be a long way from where it finally drips.

Usually, yes. The trace uses the interior marks, the roof layout and a close check of seams and details along the path. The roof is only opened to confirm and repair once the source is found.

Yes, it comes with the free survey. You only pay for the repair, once you have viewed the opening and approved a written price.

Yes. Interior checks and roof work are booked for times that suit the building, and you get notice before anyone arrives.

If there is one source, yes. Where several openings feed the same area, each is found and priced, so the leak does not come back from a second one.

Call 504-229-3955. Temporary protection goes on first, and the trace follows once it is safe to walk the roof.
