IKO Dynasty Shingled Roof Replacement in Slidell, LA
In St. Tammany Parish, a roof has to do much more than match the color of the brick. It has to deal with Gulf Coast sun, humidity, and storm seasons while passing modern code inspections. This shingled roof in Slidell, LA was planned as a complete, code-focused system — from the deck and underlayment to ventilation — to comply with 2021 IRC and 2021 IBC requirements and give the homeowners long-term confidence.

Project Overview — A New Shingled Roof in Slidell, Louisiana
For this project, the homeowners were not just looking for a cosmetic refresh. Their existing roof was aging, and they wanted a solution that would:
- Stand up to high winds and heavy rain
- Meet updated 2021 IRC and 2021 IBC codes
- Improve attic ventilation and interior comfort
- Clean up and modernize the look of their home in Slidell, Louisiana
The recommended path was a full roof replacement in Slidell, Louisiana using IKO Dynasty AR Class 3 IR shingles in Summit Grey, installed over two layers of synthetic underlayment with upgraded ventilation and accessories.
Once the work was complete, the house had a sharper profile on the street, stronger day-to-day weather protection, and a roofing system built to pass inspection — not just survive the next storm.

Why IKO Dynasty AR Class 3 IR in Summit Grey?
Shingle choice is one of the most visible decisions in any roofing project. For this shingled roof in Slidell, LA, the homeowners selected IKO Dynasty AR Class 3 IR with ArmourZone shingles in Summit Grey.
This particular line is a strong match for Gulf Coast homes because:
- Class 3 impact-resistant shingles help reduce damage from hail and flying debris.
- The ArmourZone nailing strip is engineered for secure fastening and better wind performance, a key factor in St. Tammany Parish.
- The Summit Grey color delivers a clean, modern look that works well with brick, stucco, and siding commonly found in Slidell neighborhoods.
The result is a roof that quietly adds protection where it counts while giving the home a fresh, updated appearance from the curb.

Code-Driven Roof Design (2021 IRC & 2021 IBC)
In a Gulf Coast climate, a roof has to function as an integrated system rather than a simple layer of shingles. For this project, the installation was laid out around the 2021 International Residential Code (IRC) and 2021 International Building Code (IBC) as enforced in St. Tammany Parish.
Key points included:
- Inspecting the roof deck and replacing any damaged or soft sheathing
- Using two layers of synthetic underlayment with proper overlap to align with local code requirements
- Following manufacturer fastening patterns for IKO Dynasty AR Class 3 IR shingles in the ArmourZone area
- Installing flashing, boots, and vents according to current code language and best practices
By treating code compliance as the starting point instead of an add-on, the homeowners now have a code-compliant roof installation that is easier to document for insurance, resale, or future inspections.

Two Layers of Synthetic Underlayment for Extra Protection
Underlayment is the quiet layer that does a lot of work behind the scenes. On this home, the crew installed two layers of synthetic underlayment with overlap to match St. Tammany Parish expectations based on the 2021 IRC and 2021 IBC Codes.
That approach brings several advantages:
- A tighter, more resilient water-shedding layer underneath the shingles
- Better protection on installation days if weather moves in unexpectedly
- Additional backup against wind-driven rain that can reach under shingle edges during strong storms
For a community where heavy rain bands and gusty conditions are normal parts of storm season, this underlayment system is a key part of the roof’s durability.

Upgraded Roof Ventilation — Turbines, 750 Vents and Bullet Boots
A long-lasting roof has to manage heat and moisture, not just keep the rain out. On this shingled roof in Slidell, LA, the ventilation strategy and accessories were carefully updated:
- Installed (8) Bullet Boots to seal plumbing penetrations, protect against leaks, and keep the roof surface tidy around pipe stacks.
- Installed (4) 14″ turbine vents to actively pull hot air and moisture out of the attic when wind is present.
- Installed (2) new 750 roof vents to help balance overall airflow and support a healthier attic environment.
- Added other new accessories as part of the full roof system, including fasteners and sealants specified for this type of installation.
Taken together, these upgrades improve attic ventilation, help reduce heat buildup, support shingle life, and make the home easier to cool during long Louisiana summers.
Installation Process — From Tear-Off to Final Walkthrough
To make sure the new asphalt shingle roof installation performs the way it was designed, the work followed a clear, step-by-step process.
First, the crew completed a full tear-off of the existing roofing materials, including old shingles and underlayment, down to the deck. Any compromised decking was cut out and replaced so that the new system would sit on a solid, nail-holding base.
Next, they installed the two layers of synthetic underlayment, fastening and overlapping them in patterns that align with 2021 IRC and 2021 IBC guidance and manufacturer instructions. Metal details such as drip edge and flashings were tied into the underlayment to control water at eaves, rakes, and penetrations.
Then, the IKO Dynasty AR Class 3 IR shingles in Summit Grey were installed, with attention to straight shingle lines, correct exposure, and consistent nailing within the ArmourZone. The team finished by adding ridge caps, turbine vents, 750 roof vents, and Bullet Boots, sealing all contact points for a clean, watertight finish.
To close out the job, the crew performed a detailed cleanup and a final walkthrough with the homeowners — pointing out ventilation locations, reviewing key materials used, and answering questions about ongoing maintenance and warranty coverage.
Performance Benefits for This Slidell Home
With the new system in place, the homeowners now have a roof that is better matched to everyday Gulf Coast weather as well as stronger storm events. The main benefits include:
- Storm-ready roofing in Slidell, LA using impact-resistant shingles and layered protection beneath the surface
- Improved attic ventilation through turbine vents and 750 roof vents, which supports both comfort and shingle life
- A crisper, more contemporary look thanks to the architectural profile of IKO Dynasty shingles in Summit Grey
- Assurance that the assembly was built with 2021 IRC and 2021 IBC requirements in mind for St. Tammany Parish
Instead of wondering how the roof will respond when the next weather system pushes through, the homeowners now have a documented, code-driven roofing system tailored to the realities of the Northshore.
