Roof Leak Detection in LaPlace, LA

Big Easy Roofing traces roof leaks across LaPlace and the east bank of St. John the Baptist Parish. A wet ceiling is not always a roof problem. Sometimes the trace ends at an air conditioning line or a plumbing pipe, and the parish lists trade permits separately from a re-roof.

LaPlace roof leak detection at a glance

Leak detection finds where water gets in, which is rarely right above the stain. On a LaPlace house the answer is usually the roof, but not always. The trace can end at an air conditioning condensate line or a plumbing pipe, and the written finding says which, and whose trade fixes it.

The stain is not the hole

Water travels first

Water runs along the decking and the framing before it drops, so the wet patch on the ceiling can be several feet from the entry point. Repairing the roof directly above it is the usual reason a leak comes back.

Not every leak is the roof

Pipes and AC lines too

An air conditioning condensate line, a plumbing vent pipe joint or a mechanical run in the attic can leave a ceiling stain that looks exactly like a roof leak. The trace settles which it is.

The parish lists the trades separately

Gas, mechanical, plumbing, electrical

The St. John the Baptist Parish residential permit application has separate boxes for gas, mechanical, plumbing and electrical work alongside the re-roof box. A pipe or AC fix is its own line, not part of the roofing.

The boot is roofing, the pipe is not

Where the line falls

The rubber boot and flashing around a vent pipe are part of the roof. The pipe itself, its joints and a condensate line inside the attic are normally work for a plumber or a mechanical contractor.

Not the same as an inspection

One question, one defect

An inspection records the condition of the whole roof on a date. Leak detection answers one question: where is this water getting in. They are different jobs and priced differently.

No promise of a first visit find

Some leaks are hard

Wind driven rain, low slopes and roofs with many penetrations can hide a leak that only shows in certain weather. Saying otherwise is how this service gets sold badly.

Where the stain shows, and where the water usually comes from

The position of a stain is a clue, not an answer. These are the common patterns on a house here and the source each one most often turns out to be. The last column is the part people are rarely told, which trade normally does the fix.

Where it showsOften turns out to beConfirmed byWhose trade
Middle of a ceiling, away from wallsA roof defect upslope, water travelling along the deckingTracing in the attic and on the roofRoofing

These are common patterns, not a diagnosis. A stain that appears in dry weather points away from the roof and toward a line that carries water all the time.

When the trace ends outside the roofing trade

Not every ceiling stain in LaPlace is a roof defect. The trace can end at an air conditioning condensate line, a plumbing vent pipe or another mechanical run. St. John the Baptist Parish lists trade permit categories for gas, mechanical and plumbing work separately from a re-roof, and the Permit Division can tell you how a particular repair is classified.

The parish lists trade permits separately

Building Permits page

The parish Building Permits page lists residential permit types including Re-Roof and, separately, Trade permits for gas, generator, mechanical and plumbing work.

Separate boxes on the same form

Residential permit application

The parish residential permit application asks the applicant to check all that apply, with gas, mechanical, plumbing and electrical listed as separate items from re-roof. Whether a particular fix needs a permit is a question for the Permit Division on (985) 651-5565.

A reroof follows the roof rule

R.S. 37:3737(I)

Louisiana requires any municipality or parish that issues construction permits to permit and inspect roof construction and reroofing. Whether a smaller roof repair counts is a question for the Permit Division.

What the finding tells you

Source and trade

A written finding with photographs that names where the water enters and which trade normally fixes it. If it is not the roof, you take that finding to a plumber or mechanical contractor rather than paying a roofer to guess.

Why the dry weather question matters

A stain that grows when it has not rained is rarely the roof. Air conditioning runs for long stretches of the year here, and its condensate line carries water every day it runs, rain or not.

Asking when the stain appears, and checking in dry weather as well as wet, is one of the quickest ways to tell a roof leak from a line that belongs to another trade.

What we will not claim

We will not promise to find every leak on the first visit, name a cause before we have looked, or tell you water has not reached the structure without opening it up. We will not interpret your insurance cover either, which R.S. 37:2159.1 bars.

If water is coming in right now, our emergency roof repair page covers stopping it first. Tracing it properly comes after.

Why leaks are hard to pin down on a LaPlace house

LaPlace is hot and humid for most of the year, and air conditioning runs for long stretches of it. Both work against a quick diagnosis. Water finds long paths through an attic, and a house here also has water moving through lines that have nothing to do with the roof.

Water takes the long way

It follows the decking, the rafters and the top of the ceiling before it drops, so the entry point can be several feet upslope of the stain. The trace starts in the attic, where the path is visible, and ends on the roof.

Once the entry point is confirmed, a roof repair fixes that point rather than the patch of roof above the ceiling.

The penetrations are the usual suspects

Vent pipes, exhaust vents, skylights and anything else that passes through the covering carry a joint between materials, and those joints fail before the open roof does.

Each one has an outside part that is roofing and an inside part that may not be, which is why the finding names both.

One leak, or a roof near the end

A single traced entry point on a sound roof is a repair. Several leaks on an ageing covering are a different conversation.

Where more than one point is failing, a roof inspection puts the whole roof on record so the decision is made on evidence.

Big Easy Roofing Process

Four steps. The first is inside the house, because the attic shows the water path and rules other sources in or out.

01

01 Start inside: the stain, the attic and the lines

Follow the water path across the decking and rafters, and check vent pipes and any air conditioning condensate line nearby.

02

02 Trace on the roof to the entry point

Upslope of where the water showed, at the penetrations, flashings, edges and ridge.

03

03 Write the finding

Where the water enters, photographed, and which trade normally fixes it: roofing, plumbing or mechanical.

04

04 Fix the roof defect, or hand over the finding

A roof defect is repaired and priced from the finding. A pipe or AC source goes to a plumber or mechanical contractor with the finding in hand.

Why is the stain not under the leak

Because water runs along the decking and the rafters before it drops. The entry point can be several feet upslope of the wet ceiling, which is why a repair made directly above the stain so often fails.

Could my ceiling leak be the air conditioning and not the roof

Yes. An air conditioning condensate line or drain pan can leave a stain that looks like a roof leak. A stain that appears or grows in dry weather points toward a line rather than the roof.

Who fixes a plumbing or AC leak in LaPlace

A plumber or mechanical contractor. St. John the Baptist Parish lists gas, mechanical and plumbing trade permits separately from a re-roof. The boot and flashing around a vent pipe are roofing; the pipe and a condensate line are normally plumbing or mechanical work.

Does a plumbing or AC repair need a permit in LaPlace

The parish lists trade permits for gas, mechanical and plumbing work, and its residential application has separate boxes for each. Whether a particular repair needs one is a question for the Permit Division on (985) 651-5565.

Is leak detection the same as a roof inspection

No. An inspection records the condition of the whole roof on a date. Leak detection answers one question about one defect: where this water is getting in.

Will you find the leak on the first visit

Often, but not always. Leaks that only appear in wind driven rain, on low slopes or around several penetrations can take more than one visit, and we will not promise otherwise.

Will insurance cover the leak

That is a question for your insurer. Under R.S. 37:2159.1 a Louisiana roofing contractor may not interpret your cover. The written finding and photographs are a record you can give them.
