How to price a roofing job

You price a roofing job by multiplying the measured roof area by a rate that covers materials, labor, tear off, waste, and overhead. The measurement gives you the area; the rate is where your margin lives. Here is how to set a rate that wins work without giving away profit.

Start with the measured area

Measure every plane and apply your pitch multiplier so the area reflects the real surface. This is the foundation of the bid, and getting it wrong throws off everything downstream.

Build your rate from real costs

• Materials: shingles or panels, underlayment, flashing, fasteners, and ridge.
• Labor: crew hours for the install plus tear off of the old roof.
• Waste: order more material than the bare area, since cuts and starter courses are not free.
• Overhead: disposal, permits, insurance, and the cost of running the business.

Add what the map cannot see

Steep pitch, multiple stories, hard access, and a layered tear off all add labor that area alone does not capture. Note them on the quote and adjust the price so a hard roof does not cost you the same as an easy one.

Quote fast, while you are still on site

A bid loses value the longer it takes to arrive. Measure on satellite, let the price calculate, and send the estimate the same day so you are the first real number the homeowner sees.
