Atlas Pinnacle Pristine Hearthstone FORTIFIED Roof Project in Slidell, LA
Southern Home Improvement Center completed this residential FORTIFIED Roof project in Slidell, Louisiana, using Atlas Pinnacle® Pristine architectural shingles in the Hearthstone color.
A key part of the project was the sealed roof deck. Two layers of synthetic underlayment were installed with an overlapping layout and mechanically fastened nailing pattern beneath the finished shingles.

Slidell Roofing Project Overview
This completed project is distinguished by the combination of a two-ply synthetic sealed roof deck and Atlas Pinnacle Pristine shingles in Hearthstone.

Two-Ply Synthetic Sealed Roof Deck
The sealed roof deck is installed beneath the visible roof covering. Its purpose is to provide an additional water-control layer over the wood roof deck if the shingles are damaged or displaced during severe weather.
For this Slidell project, the sealed deck was created with two layers of synthetic underlayment. The layers were arranged in overlapping courses and secured using mechanical fasteners.
This method covers the joints between the roof-deck panels and helps limit direct water entry through those joints when the finished roof covering is compromised.

Why the Nailing Pattern Matters
A two-layer synthetic system depends on more than simply covering the roof deck with underlayment. The layout of the courses, the overlaps between them, and the placement of the fasteners all contribute to the completed sealed-deck assembly.
The synthetic layers on this project were mechanically fastened to help keep the material properly positioned while the remaining roofing components were installed.
This creates a continuous secondary layer beneath the shingles instead of leaving the roof-deck joints directly exposed if the primary roof covering is damaged.

Atlas Pinnacle Pristine Shingles in Hearthstone
Atlas Pinnacle Pristine architectural shingles were installed as the finished roof covering. Their dimensional pattern gives the roof more visual depth than a traditional flat three-tab shingle.
The Hearthstone color presents a varied blend of gray, charcoal, and muted natural tones. Across the different roof planes, the color changes subtly with the direction and intensity of the sunlight.
On this light-blue Slidell home, the neutral shingle blend coordinates with the siding, white exterior trim, brick accents, and surrounding landscape without creating a harsh contrast.

Manufacturer-Listed Shingle Features
Atlas lists several product features for the Pinnacle Pristine shingle line. These features apply according to the manufacturer’s installation requirements, product documentation, and applicable warranty terms.
- Class 3 impact resistance for added resistance to impacts such as hail and wind-blown debris.
- HP42® technology with a larger shingle format and an expanded installation area.
- 3M™ Scotchgard™ Protector designed to help resist the black streaks associated with blue-green algae.
- Architectural profile that creates a dimensional pattern across the completed roof.
- Hearthstone color blend with varied neutral tones across individual shingles.
Finished Roof Details
The completed roof includes multiple intersecting roof planes, ridges, penetrations, and transitions. The consistent shingle layout helps maintain a coordinated appearance across the main home, upper story, garage section, and adjoining roof surfaces.
Close views of the completed installation show the dimensional shingle pattern, uniform courses, ridge treatment, and finished areas around the roof penetrations.
