How to read this

The Contractors State License Board lists complaints it has sent for legal action, citations it has issued, and warning letters. A complaint or accusation is an allegation, not a finding. A citation is the board's finding that a rule was broken; the contractor can appeal it. Complaints closed in the contractor's favor are never listed. Most contractors have no items.

Cost and timing

Price

About $30,000 for a full roof their typical size (24 squares, 2,450 sq ft)

How we got it: The Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com) estimates $36,417 for a standard 30-square (3,000 sq ft) asphalt shingle roof with two skylights. It is an estimate for one standard job, not a price anyone paid. We scaled it to their typical roof.

The permit form shows a lower figure: $5,800 on their typical permit ($5,600 on the typical Los Angeles roofing permit). The form records a job value for the permit fee, which is usually well below the contract price for every roofer, so it is not a price.

Permit timeline

Across Los Angeles, a roofing permit stays open about 26 days, from permit to final inspection

This is not how long the crew works at your home: most of it is waiting for the inspection. Ask them how many days the work takes. How long roofing jobs take.

What to ask before you hire

About Master Plumber Company Inc

  • Ask what the warranty covers and for how long, in writing.

Worth asking any roofing contractor

  • Can you show me proof of liability insurance and your bond?
  • Will you tear off the old roof or lay the new one over it?
  • What do you charge to replace rotted roof boards, per sheet, if you find any?
  • Who pulls the permit, and who meets the inspector?
