Roof replacement cost questions
Is the permit valuation the real cost of a roof replacement?
Not exactly. The median declared permit valuation of $5,200 is the value the applicant wrote on City of Los Angeles permits for one- and two-family re-roofs over the last 12 months. It is not a contract price, and the real cost of your roof is usually higher.
What drives the price of a roof replacement?
Size of the roof, the materials you choose, the roof's slope and access, the condition of the roof deck, and any repairs found once the old roofing is off all change the price. Work that is not on the permit also adds to the total.
Why do estimates for the same roof differ?
Each builder looks at a different roof and scope of work. One estimate may include tear-off, underlayment and flashing while another does not. Compare what each estimate covers, not only the total.

Ask for a written estimate for your specific roof, with materials and work listed. You can also check any contractor's license status with the CSLB (Contractors State License Board). Your request goes to one local builder, who will look at your home.
