New Roof Price Variables That Impact the Overall Cost

New roof price variables

There are a number of new roof price variables that impact the overall cost of a new roof.

We covered four of the major factors involved, including

  • The size of your roof and how a roofing square is calculated.
  • The pitch of your roof and how it affects labor costs.
  • How much of the old roofing material needs to be removed.
  • The materials you choose to use on your new roof.

However, these aren’t the only factors affecting the price or estimate you will get from competing companies.

We want to show you how much goes into that cost, and why the lowest estimate isn’t always going to be the best value.

New Roof Price Variables

Here are four more things that influence the price of your new roof:


From a logistical standpoint, sometimes the job itself isn’t that hard. However, at times it is difficult and time-consuming to get to the roof and bring materials in and out.

When access to your roof is difficult, it means we are going to need additional equipment and labor to tear off the roof, load the materials, and stage and install the new roof. More equipment and more time equal more cost.

Additional Components

Most people don’t know everything that goes on a new roof. You might be thinking only of the price of the final tile or shingle that’s being installed, but that’s not how a roof works.

Think of a roof as a whole waterproofing system. To work correctly, a roof has to be waterproofed underneath, and it has to have a working gutter system.

Either the underlayment or decking materials or both may need to be replaced on your new roof.

In addition, your ventilation system may need to be adjusted, and your insulation may need to be replaced.

Roof fasteners play a crucial role as well. The quality of your new roof construction can vary greatly depending on the quality of fastener due to different levels of performance and how long they last.


Did you know there are different levels of warranties?

A standard warranty backed by the roofing company covers the labor and the workmanship of the project.

However, there is also what is called an extended warranty or no-dollar-limit warranty offered by the manufacturer.

These warranties require extra materials and fees that will back the contractor’s labor and workmanship.

Additional steps are required, like an outside inspection, to ensure the roof is installed correctly.

Warranties are necessary, but they do add a bit of extra cost. If you opt for a standard roofing warranty, which typically doesn’t require any additional steps, remember you pay for what you get.

All the Trim

In addition to the underlayment, the “detail” pieces of your roof can vary widely in quality and price including:

  • Fascia
  • Rafters
  • Flashing
  • Sealants
  • High-quality lumber, for instance, costs more but also lasts a lot longer.
