What Is a Roof Dry-In Inspection?
If you’re having your roof replaced, you may hear your roofing contractor mention a dry-in inspection before the new shingles are installed.
But what exactly does that mean?
A roof dry-in inspection is typically performed after the old roofing materials have been removed, necessary decking repairs have been completed, and protective roofing materials have been installed—but before the finished shingles cover everything up.
This gives an inspector the opportunity to see important parts of the roofing system that will eventually be hidden beneath your shingles.
At Roof Wiz, we believe homeowners should understand what is happening on their roof throughout the installation process—not just what the finished roof looks like. What Is a Roof Dry-In Inspection
What Does “Drying In” a Roof Mean?
“Drying in” a roof means installing the protective materials that help prevent water from entering the home before the finished roofing material is installed.
Depending on the roofing system and local requirements, this stage can include:
- Roof decking
- Synthetic roofing underlayment
- Ice and water protection
- Drip edge
- Valley protection
- Flashing components
- Properly sealed roof penetrations
Once the roof is properly dried in, the structure has an added layer of protection while the remainder of the roofing system is installed.
What Does an Inspector Look for During a Dry-In Inspection?
The exact inspection requirements can vary depending on the municipality and the specific roofing project, but inspectors commonly review several important areas.
1. Roof Decking
Before anything is covered, the inspector may look at the condition of the roof decking.
Damaged, deteriorated, or unsuitable decking may need to be replaced or re-sheeted before the roofing installation can continue.
This is an important part of the process because shingles need a solid surface beneath them.
2. Roofing Underlayment
Underlayment is installed between the roof decking and the shingles.
Although homeowners rarely see it once their roof is finished, underlayment serves as an important secondary layer of protection against moisture.
During the dry-in stage, an inspector can verify that the underlayment has been installed in the appropriate areas and properly secured.
3. Seams and Overlaps
Roofing underlayment is installed in sections that overlap one another.
Those overlaps need to be completed correctly so water can continue moving down the roof instead of finding its way beneath the roofing system.
4. Fastening
Inspectors may also review how roofing materials are secured to the roof deck.
Proper fastening helps keep underlayment in place and prepares the roof for the next phase of installation.
5. Roof Edges, Eaves and Rakes
The perimeter of your roof plays an important role in water management.
The inspector may examine areas around the eaves, rakes and roof edges to verify that required components have been installed correctly.
6. Valleys and Other Vulnerable Areas
Roof valleys receive a large amount of water whenever it rains or snow melts.
Because of this, valleys and other transition areas often receive additional attention during both installation and inspection.
Why Does the Dry-In Inspection Happen Before Shingles?
The answer is simple: once the shingles are installed, many important roofing components are no longer visible.
A dry-in inspection gives the inspector an opportunity to review the work underneath the finished roof.
Think of it like inspecting the foundation of a house before the walls are closed.
The shingles may be the part of your roof everyone sees, but the materials underneath them are an important part of the complete roofing system.
Can Roofing Continue Before a Dry-In Inspection?
That depends on the local building department and the requirements associated with the roofing permit.
Some jurisdictions require specific stages of roofing work to be inspected before contractors can proceed.
A reputable roofing contractor should understand the inspection requirements for the community where your home is located and coordinate the project accordingly.
Roof Wiz works throughout Southwest Michigan and handles the roofing process with local requirements in mind.
Does Every Roof Replacement Require a Dry-In Inspection?
Not necessarily.
Roofing permit and inspection requirements can vary between cities, townships and counties.
The type of roofing work being performed may also affect which inspections are required.
That is why homeowners should work with a contractor who understands the permitting and inspection process in their area rather than assuming every municipality follows exactly the same procedure.
What Happens After the Dry-In Inspection?
Once the required inspection is completed and the project can proceed, the roofing crew moves into the next stage of installation.
That commonly includes installing:
- Starter shingles
- Field shingles
- Valley materials
- Flashing
- Ridge ventilation
- Hip and ridge caps
- Other finishing components
Eventually, another inspection may be performed after the roofing system is complete.
Why Roofing Inspections Matter
A roof replacement is a major investment.
Inspections provide another layer of oversight during the installation process and allow certain portions of the roofing system to be reviewed before they become hidden.
For homeowners, that can provide additional confidence that their roofing project is moving through the appropriate stages.
At Roof Wiz, we want our customers to understand that a roofing project involves much more than simply removing old shingles and installing new ones.
There is an entire roofing system underneath the finished product.
