What Goes into a Roofing Estimate

A roofing contractor stands on a ladder and inspects a roof while speaking on a cellular telephone.

If you’re looking to hire a company to replace the roof on your home, you should always get an estimate first. This will let you know if you can even afford the work and might make it clear that you should do some shopping around.

But you should also know what goes into an estimate and how a number is determined by the person or company completing the work. This will give you a better idea of what the work will entail and whether or not you’ve hired the right company for the job. So, here’s what a roofing estimate entails:

Inspection and Questioning

The first thing the estimator will do is inspect your roof and ask you a few pertinent questions. They’ll inquire about the age of the roof, whether you want it repaired or fully replaced, and what type of roof you’re looking to have installed, among other things. During the inspection process, they’ll check out the gutters, determine how many layers there are, decide if there’s going to be extra debris to remove beyond just shingles, and determine if there are any obstacles that will increase labor costs.

The Measurement

The next step will be to measure the roof. In the world of roofing, the most important unit of measurement is the “square.” One square is equal to 100 square feet of roofing surface. A roof that measures 1,500 square feet will then be 15 square.


Once the measurement of the roof is known, the estimator can then begin to consider how much material will be needed. Beyond just shingles, they’ll have to factor in the cost of nails, flashing, vents, ice and water shield, and many other materials. Then, of course, there will be the labor, rental, and overheard costs associated with the project.

The Estimate

The final step in the process should involve you receiving a formal estimate. This should include a detailed description of what work will be done, what costs will be incurred, the project timeline, the material costs, and payment details.
