Near La Verne

A single-family roof replacement in La Verne typically runs

$11,500 to $30,000

What that is based on. Public installed-cost data for California, adjusted for how La Verne is built, on a typical 18 to 28 square roof — about 1,800 to 2,800 square feet of roof surface.

What moves it up. Steep pitch, two or three old layers to strip, tile or metal instead of shingle, soft decking found once the covering is off, and a lot of chimneys, skylights or valleys.

What moves it down. A simple single-storey roof, one layer to remove, a truck that can park next to it, architectural shingle, and a crew booked outside the busy season.
