What Is Overhead and Profit (O&P)?

A general contractor carries costs that never appear as a line on the roof itself: supervision, scheduling, permits and paperwork, office staff, insurance, and a margin for taking on the risk. An estimate captures those as separate overhead and profit amounts, calculated on the repair subtotal. The arithmetic is simple. The argument is over whether a particular claim qualifies.

Adjusters commonly weigh whether the job is complicated enough that a homeowner would reasonably need a general contractor to run it. A guideline that circulates in the industry looks at repairs involving several different trades, such as roofing along with gutters, drywall, and paint. Some carriers use it and others reject it, so it is not a universal rule. Roof-only claims with a single trade are where O&P is most often left off.

Confusion tends to start with timing and wording. Some carriers hold O&P back from the first payment and release it with other withheld amounts, others handle it differently or dispute it, and the answer can turn on the policy, state law, and court decisions. Reps also mix it up with their own company’s markup. The O&P line on a claim is an item in an insurance estimate that the carrier agrees to or declines, not an automatic add-on.
