Roofing in
Lafayette Square.

A mansard is two roofs in one: a steep slate-covered face you see from the street and a low-slope or flat deck hidden behind it that you do not. Most contractors only know how to do one of those. We do both. The slate face wants matched natural slate or a designer-slate profile and soldered copper at the cresting and the dormer cheeks; the flat deck behind it wants a proper membrane or modified-bitumen system with the drainage detailed correctly. The project consultant walks both portions and the proposal covers the whole roof, not just the part you can see.

Lafayette Square is a local historic district, so the slate face is under design review and the material has to clear the board. We have done enough work on these streets to know which natural slate and which designer-slate profiles (DaVinci, Brava) pass review and which do not. The flat deck behind the mansard is not visible from the street, which gives you more latitude there, and we will tell you on site where you can save money without it ever showing.
