House roofs beside flat roofs
Elmwood is where a residential hip and a commercial membrane can be on the same block. We do not treat them as one system. A house gets a shingle or metal scope. A low-slope section gets a membrane scope, with the edge metal and the drains written down. The failure we see most often on houses is the tie-in, where water from the steep roof dumps onto a flat porch or a later room.
Jefferson Parish permits the unincorporated addresses. If the building is a leased warehouse rather than a house, say so when you call. The ladder and the scope are different.
