How these Maryland figures are worked out
We start from the national typical price per roofing square for each material, multiply it by the squares on a typical roof for each home size, then apply the Maryland index of 1.06 from our state-by-state source data. The ranges assume: full replacement with a single-layer tear-off, sound decking, average pitch (4/12 to 7/12), standard permits, and architectural shingle as the default.
A steep roof, extra layers to tear off, or rotten decking push the price up. Your exact price comes from the roofer who inspects your roof. Sources and method
