Holy Cross building stock, and what it means for a roof
Holy Cross occupies the riverfront strip of the Lower Ninth Ward, sitting on the natural levee and therefore on markedly higher ground than the blocks behind it. That elevation is why a substantial amount of genuinely old building stock survived 2005 here when so little did further back, and why the neighborhood is a designated historic district.
The surviving houses are nineteenth-century Creole cottages, shotguns and a scattering of larger center-hall houses, many with their original framing intact. They are old, they are significant, and a good number of them have had only intermittent maintenance for decades — which makes honest assessment more valuable here than a fast quote.
Why Holy Cross 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.
Long-deferred maintenance
Decades of intermittent upkeep on nineteenth-century stock means small failures have usually become deck failures by the time we are called.
River wind exposure
The levee position that kept these houses dry also puts them in the wind off the river, and ridges lift accordingly.
Original fabric under later covering
Modern shingle laid over original wood shingle or plank is common here and changes how a repair has to be approached.
Keeping a historic roof rather than losing it
A slate or clay tile roof that is shedding units is usually not finished. It is usually telling you something specific, and the specific answer is cheaper than the general one.
- Establish what is actually failing. On most historic roofs the slate outlives the copper. Valleys, step flashing and gutter linings go first, and the symptom presents as a slate problem.
- Match rather than substitute. Replacement slates are matched on color, size and thickness; tile is sourced to profile. The HDLC and the VCC both treat a visible mismatch as a change to the building, not a repair to it.
- Check the fixings, not just the units. Nail fatigue is what makes a slate roof start dropping slates at random rather than in one area. That is a re-fixing job, not a re-roofing job.
- Respect the deck. Original plank decking under a century-old slate roof behaves differently from modern sheathing, and modern underlayment has to be specified to suit it.
- Document for review. Before-and-after photographs and a written material schedule are what a historic-district review actually wants to see.
What the commissions will not accept
Design guidance for the local historic districts is explicit that standing seam metal is typically not an appropriate material to replace asphalt, slate or asbestos roofing. Traditional slate and clay tile are supported for restoration, and modern substitutes are permitted only where they match in material and color. If a contractor proposes stripping your slate for metal because it is quicker, that is a review problem as well as a preservation one.
A re-roofing permit is required in Orleans Parish — and three different commissions may review it
Residential re-roofing permits are applied for through the Department of Safety and Permits. Properties inside a historic district require additional review time before the permit is issued.
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.

Slate & Tile Roof Restoration in Holy Cross — straight answers
Can my slate roof be repaired rather than replaced?
Usually, yes. Slate is one of the few coverings where individual units genuinely can be replaced, and a roof dropping the occasional slate is more often telling you the fixings or the copper valleys are tired than that the slate itself is finished.
Can I put metal on instead? It is cheaper.
Not in a local historic district, in most cases. Design guidance is explicit that standing seam metal is typically not an appropriate replacement for asphalt, slate or asbestos roofing in these districts. Traditional slate and clay tile are supported for restoration, and substitutes have to match in material and color.
How do you match a slate or tile that is no longer made?
On color, size and thickness for slate, and on profile for tile, sourcing salvaged or matched stock rather than putting the nearest available item on the roof. A visible mismatch is treated by the HDLC and the VCC as a change to the building rather than a repair to it.
My house survived Katrina — does that mean the roof is sound?
It means the house was on high enough ground, which is not the same thing. Surviving the flood says nothing about twenty further years of sun, rain and wind on the covering above it. On Holy Cross stock we most often find original structure in decent condition under a covering that is long past its service life, which is a good position to be in but still one that needs acting on.
