New Roof

Average cost: $9,454

Roof work is the project most likely to be entirely turned over to a contractor, with only 9 percent of Houzz users claiming to do it themselves.

A new roof will recoup 58 percent of its cost. The life span of a new roof can vary, but those made of slate, copper and clay and concrete can last more than 50 years. Asphalt shingles last 20 years or so.
