If you are planning a roof replacement or major roof repair, one of the first questions to answer is whether you need a building permit. For homeowners in Wicomico County, the answer depends on the scope of the work, the condition of the existing roof, and the property’s exact location.
A full roof replacement generally requires a residential building permit. Minor, non-structural repairs may be exempt, but homeowners should confirm the requirements with the appropriate permitting office before work begins.
This guide explains the basics for homeowners searching for roofing companies in Salisbury, MD, hiring a roofer in Salisbury, or planning Salisbury roofing work anywhere in Wicomico County.
> Important: Permit requirements can change, and the permitting authority may differ depending on whether your property is in unincorporated Wicomico County or inside the City of Salisbury. Always confirm your project requirements directly with the appropriate office.
When Is a Roofing Permit Generally Required?
A permit is generally required when roofing work involves a substantial change to the building or roofing system. For most homeowners, this includes:
- A full roof replacement
- Removing existing roofing materials down to the roof deck
- Replacing or repairing damaged roof decking
- Repairing or altering structural framing
- Installing roofing over multiple existing layers when permitted
- Making changes that affect the roof’s structure, ventilation, or load
- Reconstructing a roof after significant storm damage
A complete tear-off is more than a simple cosmetic repair. It exposes the roof deck, may reveal structural damage, and requires the new roofing system to be installed according to applicable building codes. For that reason, homeowners should expect a permit to be required for a full replacement.
The Wicomico County residential permit information describes ordinary, non-structural repairs and replacements as generally exempt from permitting. However, a full re-roofing project should not automatically be treated as an ordinary repair.

When Might a Small Roof Repair Be Exempt?
Some minor roofing work may not require a building permit when it is non-structural. Examples may include:
- Patching a small leak
- Replacing a few damaged or missing shingles
- Repairing limited flashing or sealant failures
- Replacing a small area of roofing material
- Completing a minor repair that does not affect framing or the roof deck
A small repair is sometimes described as being under approximately 100 square feet, but this should be treated only as a practical guideline, not a guaranteed exemption. The county may evaluate the repair based on its size, materials, location, and whether it affects structural components.
For example, replacing a few shingles after wind damage may be considered an ordinary repair. Replacing a large section of roof, repairing rotted decking, or rebuilding a damaged roof edge may require a permit even if the project is not a complete roof replacement.
Before scheduling work, describe the project clearly to the permitting office. Explain:
- How much roofing will be removed or replaced
- Whether the work includes a tear-off
- Whether the roof deck or framing may need repairs
- Whether the work is related to storm damage
- Whether the project is located inside Salisbury city limits
Getting confirmation in advance can help prevent delays and unexpected compliance issues.
What Is the Three-Layer Tear-Off Rule?
One of the most important considerations is the number of existing roofing layers.
As a general code requirement, asphalt shingle roofs are typically limited to two layers. If three or more existing layers are present, the existing roofing must be removed before a new roof is installed. The tear-off generally continues down to the roof deck so the deck can be inspected and the new roofing system can be installed properly.
A contractor should not simply cover a roof with a fourth layer. Too many layers can:
- Add excessive weight to the roof structure
- Conceal rotted or damaged decking
- Prevent proper fastening of new shingles
- Create uneven surfaces and premature failures
- Complicate future repairs
- Lead to code compliance problems
During an inspection, a professional roofer can often identify multiple layers at roof edges, rake edges, wall intersections, or areas where flashing has been modified. The exact number of layers may not be known until the work begins.
If your roof has three or more layers, plan for a permitted replacement and discuss the possibility of deck repairs before the project starts.

Does the Contractor Need an MHIC License?
For residential home improvement work in Maryland, the contractor entering into the agreement with the homeowner generally must hold an active Maryland Home Improvement Commission, or MHIC, license.
Roof replacement and residential roof repair fall within the type of home improvement work regulated by the MHIC. Homeowners should ask for the contractor’s MHIC license number and verify its status through the Maryland Home Improvement Commission before signing a contract.
An MHIC license is separate from a building permit:
- The MHIC license authorizes a contractor to perform regulated residential home improvement work.
- The building permit authorizes a specific construction project at a specific property.
- The inspection process helps confirm that the permitted work complies with applicable requirements.
A contractor should be able to explain who will apply for the permit, which permit is needed, and what inspections, if any, will be required. Homeowners should be cautious if a contractor insists that a full replacement does not require a permit without confirming that position with the local building office.
Where Do You Apply for a Wicomico County Roofing Permit?
For properties in unincorporated Wicomico County, contact the Wicomico County Permits and Inspections Office:
Wicomico County Permits and Inspections Office
Government Office Building
125 N. Division St., Room 201
Salisbury, MD 21801
Phone: 410-548-4810
Additional county contact: 410-548-4860
You can also begin through the county’s permit application and online services page. Before visiting or submitting an application, confirm the current office procedures, required documents, fees, and inspection requirements.
The permit application may require information such as:
- Property address and legal description
- Owner information
- Contractor name and license information
- Description of the proposed roofing work
- Roofing materials and system specifications
- Information about the existing roofing layers
- Details regarding any deck or structural repairs
- Drawings or additional documents when requested
For a straightforward re-roofing project, the county may not require the same level of documentation as a new home or major structural renovation. However, the permitting office determines what must be submitted.
What If the Home Is Inside Salisbury City Limits?
The City of Salisbury has its own building and permitting procedures. A property located inside the city may not use the county’s process for building permits, even though it is geographically located in Wicomico County.
Before applying, verify the property’s jurisdiction. If the home is inside Salisbury city limits, review the City of Salisbury building permit guidelines and procedures or contact the city’s building office for current instructions.
This distinction is important for homeowners comparing a roofer in Salisbury or evaluating Salisbury roofing estimates. The correct permitting authority is based on the property’s location, not simply the mailing address.
What Happens If You Skip a Required Permit?
Starting work without a required permit can create problems for both the homeowner and contractor. Potential consequences may include:
- A stop-work order
- Fines or additional fees
- Required removal or correction of non-compliant work
- Delays in completing the project
- Difficulty selling or refinancing the property
- Questions about whether work meets code
- Potential complications with an insurance claim
- Problems with future inspections or renovations
A permit does not guarantee that a roof will be installed correctly, but skipping a required permit removes an important part of the local review and inspection process. It may also make it harder to document the work later.
If storm damage is involved, keep photographs, estimates, permit records, inspection results, invoices, and warranty documents together. These records can help demonstrate what work was completed and when.
