South Shore means Jefferson Parish here
People say “South Shore” for everything on this side of the lake, including New Orleans. For roofing, that mixes two different stocks of houses. This page is Metairie, Kenner, Harahan, River Ridge, and Elmwood. The Garden District, Uptown, Mid-City, Lakeview, and the Quarter are on the New Orleans page, because slate, historic review, and flat parapet roofs are a different scope.
Jefferson Parish roofs are mostly asphalt. Old Metairie adds taller, more complicated roofs and the occasional tile or metal accent. Bucktown and the lakefront camps are lower and more exposed. Kenner’s Lakeshore and University City houses were repaired and replaced in waves after major storms, so the age of the shingles is often the age of that rebuild, not the age of the slab.
