St. Roch building stock, and what it means for a roof
St. Roch grew around the St. Roch Chapel and its Campo Santo cemetery, filling in through the later nineteenth century with shotguns, doubles and Creole cottages built for working households. The framing on this stock is generally cypress and generally sound; it is the coverings that have had a harder life.
A great many roofs here are on their last covering cycle — three-tab shingle laid fifteen or twenty years ago, now well into granule loss, with the algae streaking that this climate produces on any aging asphalt roof. The honest conversation in St. Roch is usually about timing a replacement rather than finding a repair, and about what can reasonably be deferred.
Why St. Roch roofs fail the way they do
Three things we see repeatedly on this stock — not a generic list, and not the same three as the next neighborhood over.
End-of-life granule loss
Three-tab shingle in this climate loses its granules and goes brittle. Once that starts, patching buys months, not years.
Algae streaking
The black streaking on these roofs is algae feeding on the shingle. It is cosmetic at first and a covering-life issue later.
Vent boot cracking
Rubber plumbing-vent boots perish in the UV load here well before the shingle around them does. A cheap part, a common leak.
Six places a New Orleans roof lets water in
Almost none of them are the open field of shingle or slate. They are the details around it — and the stain on your ceiling is rarely under any of them.
Flashing
Chimneys, walls, skylights and vent stacks. The single most common entry point on any pitched roof here, and the least visible from the ground.
Valleys
Where two slopes meet, water concentrates. On Uptown and Garden District roofs the copper valley usually fails before the covering above it does.
Pipe boots
The rubber collar around a plumbing vent perishes in Gulf UV years before the roof around it. A cheap part and a very common leak.
Parapet and party walls
Dense Quarter, Marigny and townhouse stock shares walls. Water entering at a neighboring parapet arrives inside your top floor.
Pitched-to-flat transitions
A pitched front meeting a low-slope rear wing is standard on this city’s older houses, and that junction is the standard place it leaks.
Wind-driven intrusion
Rain forced horizontally under courses and into vents during a storm, leaving no visible damage to the covering at all afterwards.
Why the stain is not the leak
Water enters the roof, runs along the top of the decking, follows a rafter downhill and drops at the first obstruction it meets — a nail, a joint, a light fitting. On a long New Orleans shotgun that can be twenty feet from the entry point, and on a camelback it can be a whole story away. Patching directly above the stain treats the exit. That is why the same spot gets patched three times and leaks a fourth.
How we trace it
- Start inside. Where the stain is, how it runs, and which way the framing above it travels.
- Work uphill on the roof. Every detail above the stain line gets checked before anything gets opened up.
- Check the deck, not just the covering. In this city that includes looking for termite galleries in the rafters, which changes the job entirely if they are there.
- Confirm before repairing. Water-test the suspected entry where it is safe to do so, so the repair is aimed at something proven rather than assumed.
- Write it down. Findings, photographs and price before any repair starts.
If the covering across the whole roof has reached the end of its life rather than failing at one detail, that is a different conversation — see roof repair or roof replacement. We will tell you which one you are actually in.
The part of a New Orleans roof nobody photographs: what the Formosans have done to the framing
Greater New Orleans spends an estimated $300 million a year on Formosan termite control and the repairs that follow. Formosan subterranean termites are specifically known to colonize roof framing, and colonies reach into the millions. Any roofer working this city who does not open up a suspect deck and look is not doing the job.
Where we find this, we say so and we stop. Structural damage of this kind needs an entomologist and, where load-bearing members are involved, a structural engineer — alongside the roofer, not instead of one. Laying a new covering over compromised framing hides a structural problem under a twenty-year warranty, and we will not do it.
Four stages, no surprises
Inspection
Someone goes onto the roof. Not a drive-by, not a satellite image — the covering, the flashing, the valleys and the deck condition, looked at directly.
Diagnosis
What has failed and why, traced to the actual entry point rather than the spot where water shows up inside.
Written scope
What we found, what we propose, and what it costs, in writing with photographs. No number quoted cold over the phone.
The work
Carried out to the agreed scope, dried in each day, site cleared, and documented for your records and your insurer.
Working around St. Roch Market, St. Roch Cemetery & Campo Santo, St. Claude Avenue and the surrounding streets. If your address is in St. Roch, it is in the service area — there is no travel surcharge anywhere inside Orleans Parish.

Roof Leak Repair in St. Roch — straight answers
You patched where the stain is and it still leaks. Why?
Because the stain is where the water exits, not where it enters. Water runs along the top of the decking and drops at the first obstruction it meets, which on a long shotgun or a camelback can be a considerable distance from the actual entry point. Until the entry point is found, every patch is aimed at the wrong place.
Can you find a leak that only happens in heavy rain?
Usually, yes. Intermittent leaks are almost always wind-driven intrusion or a detail that only fails under volume - a valley that overtops, a parapet junction, a vent that only takes water at a certain angle. We can water-test suspected entry points where it is safe to do so rather than waiting for the next storm.
Is the ceiling stain the size of the problem?
No, and it is usually much smaller than the wet area above it. By the time it is visible on a ceiling the water has already spread across the decking and insulation. That is why we look at the roof rather than pricing from the size of the mark inside.
How do I know whether to repair or just replace it?
Condition of the covering across the whole roof, not just at the leak. If the shingle is brittle, losing granules and cracking when it is walked, then a repair is money spent on a roof that will need replacing shortly anyway, and we will say so. If the field is sound and one detail has failed, a repair is the right call and we will say that too. Either way you get it in writing after someone has actually been up there.
