Three trades, read as one wall.

Shingle, slate, cedar, metal and rubber, with free inspections and a $100 roofing and gutter tune-up on offer. Nail pops, chimney and valley flashing and ice-dam damage at the eaves are what actually fails first on a Montgomery County roof, and a tear off goes to the deck so nothing soft gets covered back up. Slate and cedar are their own trade, repaired and matched rather than replaced by default, and storm damage gets answered 24 hours.

Brands installedGAF, CertainTeed, Owens Corning, Tamko

Cedar shingle, clapboard, dutch lap and vinyl, with matching or contrasting trim quoted as part of the job rather than as an extra. What is behind the old course, the sheathing, the house wrap and whether the soffit was ever ventilated, decides how long the new siding lasts. Seamless gutters, guards and cleaning go on the same visit, because the eaves are already open and staged for the roof crew.

Brands installedCertainTeed, Mastic, Variform

Double hung, casement and awning, bay and bow, sliders and specialty shapes, sized to the opening rather than the other way around. Entry, patio, sliding glass, storm and French doors, hung and weathered properly. Capping is the finish that lasts: wood eaves, window and door trim and garage door trim wrapped so none of it needs repainting every few years.
