Homeowners in Millbrae pay between $10,800 and $20,600 for a full roof replacement on a typical 2,000 sq ft home — depending on material, pitch, and current roof condition. San Mateo County’s hillside SFO-adjacent homes present unique roofing considerations that affect both cost and material choice.
