St. Tammany is not a New Orleans roof
A North Shore house is usually a single-family plan with an asphalt hip or a simple gable, not a slate mansion and not a parapet flat. Old Mandeville and Old Covington still have smaller Acadian and cottage roofs under the oaks. Eden Isles and the Mandeville lakefront add raised houses and wind off the water. Slidell’s subdivisions are larger asphalt roofs, many of them now old enough that the pipe boots and the ridge are the first leaks.
Folsom, Pearl River, Lacombe, and Abita Springs mix in metal on outbuildings and on houses with longer drives. We treat the North Shore as one service area because the weather and the parish are shared, and we still write the scope for the house in front of us. Mandeville is not Slidell.
