Roof Leak Detection in Mandeville, LA

Big Easy Roofing traces leaks across Mandeville and the Lake Pontchartrain north shore. The trace keeps roof water and ground-level water on separate pieces of paper, because the city floodplain office owns the second one and we do not.

Mandeville roof leak detection at a glance

A leak trace is a methodical photographic record of where water is entering the house. On a Mandeville roof we also note whether the water is coming from above or from below, because at seven feet of elevation on the north shore of Lake Pontchartrain both are possible after the same storm.

A written trace with photographs

Not a verbal guess

Every accessible ceiling stain, attic dampness point and roof-surface finding is photographed and dated, with the location on the house noted. A verbal diagnosis is not a trace.

Roof water or ground water

Two separate records

Water through the roof shows from above: wet decking, line of drips, stained ceiling. Water from the floodplain shows from below: wet floors, wall stains that start low. We photograph both patterns separately.

The city floodplain office handles the other half

Lauren Brinkman, (985) 624-3103

If the trace shows water came in from ground level, the city Flood Protection page names Lauren Brinkman as the Floodplain Administrator at (985) 624-3103 or lbrinkman@cityofmandeville.com. That is a different office than ours.

Article 8.3 is her call, not ours

10-year cumulative substantial damage

The city's Article 8.3 Flood Damage Prevention Regulations use a 10-year cumulative rule for substantial damage assessments after a flood. Whether that rule applies to a specific address is the city's call. We do not interpret it on your roof.

Elevations noted on each photo

So the record is readable

Each photograph has the floor and the vertical position recorded, so a later reader can see at a glance whether water was coming down from a roof entry or up from a ground entry.

What we do not interpret

Your insurance cover

Under R.S. 37:2159.1 a Louisiana roofing contractor may not interpret your insurance cover. The trace records the leak and its path; your insurer and any public adjuster read your policy.

Roof water or ground water, kept on separate paper

A north-shore house at seven feet of elevation can see water from a roof failure, from the floodplain, or from both after one bad storm. The table is how our trace separates them in the written record.

The trace puts each photograph into one of these rows, with the elevation on the photograph. The reader can see on one page where the water came from and whose conversation the next step is.

What the city floodplain office owns, and what we do

The city of Mandeville runs its own floodplain office, separate from the parish. On a leak question, that office matters because it owns ground-level water, substantial damage assessments and the 10-year cumulative rule. We own the roof scope.

Lauren Brinkman

Floodplain Administrator

The city Flood Protection page names Lauren Brinkman as Floodplain Administrator at (985) 624-3103 or lbrinkman@cityofmandeville.com. That is the contact the city publishes for a flood zone or substantial damage question on a specific address.

Article 8.3

Flood Damage Prevention Regulations

The Flood Protection page says "After a flood, the floodplain office coordinates substantial damage assessments" under Article 8.3 and a 10-year cumulative rule. That is the city's framework, not ours.

What we hand her

A clean roof scope

Our trace is written specifically about the roof entry: the location on the roof, the path to the stain, the fix. That makes the city floodplain conversation about the OTHER water, cleanly, not about our scope.

What she hands us

A floodplain determination

Where a specific address has a floodplain question, the Floodplain Administrator answers it. We do not. Our scope is written independently and does not depend on her answer.

Why the paperwork separation matters

Mixing roof water and ground water in one scope is how insurance claims and city floodplain assessments end up contradicting each other. Keeping the two records separate is cheap on our side and expensive if it is not done.

A homeowner can file the roof scope with the insurer and the floodplain determination with the city independently, which is how the two systems are meant to work.

What the leak trace actually produces

A written document with dated photographs, elevations noted, the identified entry point and the recommended fix. Any flashing or flashing repair scope follows from this document.

Lakeside leaks on a north-shore house

Lake Pontchartrain humidity and the north-shore wind pattern give lakeside houses their own leak signatures. The trace reads for the ones the inland cities do not see.

Wind-driven rain against the lake-facing wall

A roof detail that sheds rain going straight down can still take water driven horizontally against a vent, a chimney flashing or a wall junction. On the north shore, lake-facing penetrations and wall tie-ins are what the trace photographs first.

The stain inside is often at the opposite end of the house from the entry point, because water tracks along framing before it drops.

Humidity in the attic

North-shore air carries moisture. An attic without working ventilation condenses that moisture on the underside of the deck, which reads as a leak to a visual inspection but is not a roof entry.

The trace separates the two with elevation notes and whether moisture is at the highest attic point (condensation) or on the deck below a known penetration (roof entry).

Older housing stock, newer housing stock

Many Old Mandeville houses were built with construction details that differ from the post-2000 construction around the city, so common leak points often look different between the two. The trace adapts to the housing on site; one checklist does not fit both.

A chimney flashing on an older house and a modern pipe boot on a newer house can produce the same stain pattern and have completely different repair scopes.

Big Easy Roofing Process

Four steps. The trace runs top-down from the roof, and bottom-up from any stain, so the two meet in the middle at the actual entry point.

01

01 Walk the ceiling stains

Each stain is photographed, dated and marked with its elevation and the direction of the house. The pattern (drip, spread, wall-start) is noted.

02

02 Enter the attic where reachable

The underside of the deck is photographed above and around each stain. Moisture at the highest point reads as condensation; moisture below a penetration reads as roof entry.

03

03 Walk the roof

The exterior of each penetration, flashing and wall tie-in above the attic signs is photographed, with the lake-facing side given extra attention on north-shore addresses.

04

04 Write the trace

A single document with the ceiling, attic and roof photos matched up, the identified entry point, the recommended fix, and a note on whether the city floodplain office is the next conversation for a parallel ground-water record.

What do I get from a leak trace

A written document with dated photographs of every ceiling stain, every attic finding and every roof-side detail that could be the entry point, with elevations noted on each photograph.

Why keep roof water and ground water separate

Because the city floodplain office owns ground water and we own the roof. Mixing them in one scope is how insurance and floodplain records end up contradicting each other.

Who handles ground-level water in Mandeville

The city of Mandeville Floodplain Administrator, Lauren Brinkman, at (985) 624-3103 or lbrinkman@cityofmandeville.com. The Flood Protection page says that office coordinates substantial damage assessments after a flood under Article 8.3.

Is condensation a leak

Not technically. Condensation on the underside of the deck or on attic surfaces reads to a visual inspection like a leak but is a ventilation or vapour issue. The trace tells them apart with elevation notes.

Why is the stain nowhere near the roof damage

Water tracks along framing and decking before it drops, so the entry point and the stain may not be directly above one another. The trace starts top-down and bottom-
