When a roofing project begins, sometimes new issues are discovered after the old roof is removed. When that happens, roofing companies use something called a change order to officially document any updates to the project.
A roofing change order is a written update to the original contract that explains changes to the scope of work, materials, timeline, or total cost after the project has already been approved.
In simple terms, it’s the process used to document and approve any changes that happen once work is underway.
Change orders are common in roofing projects and, in many situations, they’re completely necessary. But if homeowners don’t understand how they work, they can lead to confusion, delays, or unexpected costs.
Key Takeaways:
A roofing change order is a written update to the original contract.
Change orders are commonly used when hidden issues are discovered during the project.
Common causes include rotten decking, ventilation upgrades, or material changes.
A professional roofing company should explain the issue clearly before work continues.
All pricing, scope changes, and approvals should be documented in writing.
Homeowners should never feel pressured to approve a change order immediately.

What does a roofing change order include?
A professional roofing change order should clearly explain what is changing and why.
Most roofing change orders include:
A description of the new work or issue discovered
The reason for the change
Any adjustments to the total project cost
Updates to the timeline, if necessary
Approval signatures before additional work begins
Think of it as a paper trail that protects both the homeowner and the roofing company.
Without written documentation, there’s often no clear agreement about what changed, which is where many roofing disputes begin.
Why do change orders happen in roofing?
In many cases, change orders happen because certain problems cannot be fully seen during the initial roof inspection.
This is especially common throughout the CSRA, where storms, humidity, moisture exposure, and aging roofing systems can create hidden damage beneath the shingles.
Here are some of the most common reasons change orders happen during roofing projects.
1. Hidden structural damage
Once shingles are removed, contractors may discover:
Rotten wood decking
Water damage
Mold or soft spots
Damaged roof framing components
These problems usually must be repaired before the new roof can be installed properly.
2. Ventilation or code upgrades
Sometimes an existing roofing system no longer meets current ventilation or building code standards.
This may require:
Adding ridge vents
Installing intake ventilation
Improving attic airflow
Updating parts of the roofing system to meet modern code requirements
3. Material or design changes
Some homeowners choose to make upgrades after the project begins.
Examples include:
Switching to a higher-quality shingle
Changing colors or styles
Upgrading underlayment
Adding enhanced roofing components
4. Measurement or scope adjustments
Even detailed roofing estimates occasionally require adjustments due to:
Roof size variations
Complex roof designs
Unexpected labor requirements
Additional layers or materials discovered during tear-off
Does a change order mean your roofer did something wrong?
Not necessarily.
A change order does not automatically mean the original estimate was inaccurate or misleading.
Roofing projects involve unknown conditions, and some issues simply cannot be confirmed until the roof is opened up.
However, there are situations where change orders can become a warning sign.
Potential roofing change order red flags
Homeowners should pay attention if they experience:
Multiple large change orders early in the project
Charges for problems that should have been visible during inspection
Pressure to approve changes immediately without explanation
Vague descriptions or unclear pricing
No written documentation
A trustworthy roofing contractor should clearly explain the issue, provide documentation or photos when possible, and give you time to review the change before work continues.
How much can a roofing change order affect the cost?
The cost impact of a roofing change order can vary significantly depending on what is discovered.
In general:
Minor repairs, like replacing a small section of decking, may add a few hundred dollars
Moderate repairs, such as larger decking replacement or ventilation improvements, can increase costs further
Major structural issues can significantly increase the total project price
Homeowners should always be informed about pricing changes and approve the updated scope before additional work is completed.
How can homeowners protect themselves from roofing change order issues?
There are several ways homeowners can reduce confusion and avoid unexpected surprises during a roofing project.
Ask about potential change orders upfront
A professional roofing company should explain possible hidden issues before the project begins.
Make sure everything is documented
Never rely on verbal agreements during a roofing project. All updates should be written and approved.
Review the estimate carefully
Detailed roofing estimates typically reduce misunderstandings later in the project.
Don’t rush approvals
If a change order is presented, take time to fully understand what is changing and why.
What does a trustworthy roofing change order process look like?
A professional roofing company should:
Clearly communicate the issue
Provide photos or walkthroughs when possible
Explain why the change is necessary
Offer transparent pricing
Get approval before moving forward
This level of transparency helps homeowners stay informed and maintain control throughout the roofing project.
The bottom line
A roofing change order is not automatically something homeowners should panic about, but it is something every homeowner should understand before starting a roofing project.
It’s simply a structured process used to document changes when new information or hidden problems are discovered during the job.
When handled properly, change orders create transparency and protect both the homeowner and the contractor.
When handled poorly, they can lead to confusion, frustration, and unexpected costs.
Understanding how roofing change orders work can help homeowners make better decisions and avoid unnecessary stress during the project.
