Frequently Asked Questions
Does the price per square include labor?
Only if you fold labor into the figure. Material-only and installed prices differ a lot — make sure you know which you're entering.
Why might a real quote be higher?
Quotes add tear-off, disposal, underlayment, flashing, drip edge, gutters, and complexity for steep or cut-up roofs.
Do steep roofs cost more?
Usually yes — steeper roofs take more time, safety gear, and waste, which raises the installed price.
Important Disclaimer
