What Drives Roof Replacement Cost Around Chicago
- roof size in squares and the number of layers being removed
- pitch, height and the number of valleys, dormers and penetrations
- how much decking needs replacing once the old roof is off
- the shingle line you choose (architectural vs. designer)
- ventilation upgrades and new flashing at chimneys and walls
Every roof is priced after an inspection. For the full process, see roof replacement in Chicago. In Schaumburg, see roof replacement in Schaumburg.
Roof Squares, Explained
Roofers measure in squares. One square is 100 square feet of roof surface. Your roof’s area is larger than your home’s footprint because of the pitch and the overhangs, so a steeper roof means more squares, more material and more labor.
Complexity matters as much as size. Every valley, dormer, skylight and chimney adds flashing work and waste, which is why two homes with the same square footage can have very different roof estimates.
FAQ
Is the calculator an exact quote?
No. It's a starting point for planning. Your written estimate comes after we inspect the roof, check the decking and count layers.
Does insurance cover roof replacement?
If the damage comes from a covered event, such as hail or wind, it may. Wear and age usually aren't covered. See our insurance claims page.
