Slate & Tile Roof Restoration in Gentilly Terrace, New Orleans
“Houses on hills” — California bungalows deliberately raised on terraced lots from 1909 onward. Wide eaves, low pitches and a distinctive silhouette that needs its own approach.

Gentilly Terrace building stock, and what it means for a roof
Gentilly Terrace was marketed from 1909 with the slogan “houses on hills” — an unusual thing to promise in New Orleans, achieved by terracing the lots so each bungalow sits visibly raised above the street. The architecture is California bungalow: low-pitched roofs, wide overhanging eaves, exposed rafter tails, deep front porches.
That style creates a specific roofing profile. Low pitch means water moves slowly and wind-driven rain can track back under the covering; wide eaves mean a great deal of exposed soffit and rafter tail in a humid climate; and the deep porch roofs tie into the main roof at a shallower angle still. Much of Gentilly flooded in 2005 and carries mixed repair history on top of all that.
Why Gentilly Terrace 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.
Low-pitch water tracking
Shallow bungalow pitches let wind-driven rain work back up under the courses, which standard fixing patterns do not account for.
Rafter-tail and soffit rot
Wide exposed eaves in 63 inches of annual rain and constant humidity rot from the underside, out of sight from the ground.
Porch roof tie-ins
The deep front porch roof meets the main roof at a very shallow angle. It is the signature Gentilly Terrace leak.
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.
Working around Dillard University, Gentilly Boulevard, Elysian Fields Avenue and the surrounding streets. If your address is in Gentilly Terrace, it is in the service area — there is no travel surcharge anywhere inside Orleans Parish.

Slate & Tile Roof Restoration in Gentilly Terrace — 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 bungalow’s roof is quite flat — is that why it keeps leaking?
It is a large part of it. California bungalow pitches are shallow by design, and a shallow pitch in a wind-driven-rain climate lets water move sideways and upward under the covering rather than straight off it. The fix is rarely to change the pitch — it is to use the right underlayment and the right fixing and lapping pattern for a low slope, which many previous re-roofs on this stock simply did not do.
