Owens Corning COOL Roof Replacement in Northridge, CA
This Northridge, California home had reached the point where its aging roof could no longer simply be maintained—the roofing system needed to be replaced.
The existing presidential-style shingles were severely worn, with extensive deterioration that had progressed to the point where the underlying fibers were visibly exposed. Rather than replacing the old roof with a basic shingle system, the homeowner wanted an upgraded roof that would preserve the dimensional appearance of the home while providing modern roofing components, improved attic ventilation, and long-term manufacturer-backed warranty protection.
Ark Roofing & Construction completed the roof replacement with an Owens Corning Duration® COOL Plus roofing system in Midnight, creating the dark, dimensional appearance the homeowner wanted while upgrading the complete roofing assembly underneath.
The new system included Titanium® UDL50 synthetic underlayment, additional ice-and-water protection at vulnerable roof areas, and an upgraded attic ventilation system designed to improve airflow through the attic.

Replacing a Severely Worn Presidential Shingle Roof
The condition of the original roof made replacement necessary.
Years of exposure had worn away much of the protective surface of the existing shingles. In multiple areas, deterioration had progressed far enough that the fibers within the roofing material were visible.
That kind of deterioration is substantially different from normal cosmetic aging.
As asphalt shingles age, their protective surface can gradually deteriorate. Once a roof becomes significantly worn, simply addressing isolated areas does not restore the performance of the overall roofing system.
For this Northridge homeowner, the objective was therefore not to patch an old roof. It was to replace it with a complete roofing system designed for the years ahead.
Preserving the Dimensional Look of the Home
Performance was important, but appearance mattered too.
The previous presidential-style shingles created a substantial, dimensional look across the home’s large roof planes. The homeowner wanted the replacement roof to maintain that visual character rather than switching to a roof that appeared noticeably flatter or less defined.
Owens Corning Duration® COOL Plus in Midnight provided the combination the homeowner was looking for.
The dark Midnight color creates strong definition across the roof while complementing the home’s light exterior. From the aerial view, the new shingles emphasize the home’s hips, ridges, valleys, and intersecting roof sections and give the finished roof a clean, consistent appearance.
The result is an updated roofing system without sacrificing the strong roofline that contributes so much to the home’s architectural character.
Owens Corning Duration® COOL Plus Midnight Shingles
The finished roof uses Owens Corning Duration® COOL Plus shingles in Midnight, part of Owens Corning’s cool-roof product offering.
Cool roofing products use specially designed granules to increase solar reflectance compared with conventional dark roofing materials. Owens Corning introduced Midnight specifically as a darker color option within its COOL Plus line, allowing homeowners to achieve a dark roof appearance while using a cool-roof shingle product.
Actual building and energy performance can vary based on the home, insulation, ventilation, climate, roof design, and other factors.
For this Northridge home, the product was also a strong aesthetic match. Midnight provides the deep color the homeowner wanted while the dimensional shingle design complements the home’s prominent pitched roof.

A Complete Roofing System Beneath the Shingles
A roof replacement involves much more than the shingles visible from the street.
The components underneath those shingles are critical to managing water and protecting the roof deck.
For this Northridge project, Ark Roofing & Construction installed Titanium® UDL50 synthetic underlayment as part of the new roofing assembly.
Synthetic underlayment creates an important secondary layer between the roof deck and the finished shingles. It is one part of a complete system in which shingles, underlayment, flashing, water protection, ventilation, and other roofing components work together.
Replacing the worn roof gave Ark Roofing & Construction the opportunity to address these components as a complete system rather than simply covering an aging roofing assembly.
Additional Water Protection at Valleys and Roof Penetrations
Certain areas of a roof deserve additional attention because of the amount of water they encounter or the complexity of their transitions.
On this home, that included the roof valleys and penetrations.
Valleys collect runoff from adjoining roof planes and channel that water toward the edge of the roof. Roof penetrations interrupt the otherwise continuous roofing surface and therefore require careful integration with the surrounding roofing materials.
Ark Roofing & Construction installed ice-and-water protection in these vulnerable areas to provide an additional protective layer beneath the finished roofing system.
The goal is redundancy.
The shingles provide the primary roof covering, while properly installed underlayment, water-protection membranes, flashing, and other components provide additional layers of protection underneath.

Upgraded Attic Ventilation
The homeowner’s new roof also included an important improvement that isn’t as visually obvious as the Midnight shingles: upgraded attic ventilation.
A roofing system needs to do more than shed rain. The roof and attic should function together as part of the home’s overall building system.
Properly designed attic ventilation allows air to circulate through the attic space. Balanced ventilation can help manage heat and moisture accumulation and is an important consideration for long-term roofing performance.
Owens Corning itself advises homeowners to have contractors evaluate attic ventilation and notes the importance of adequate ventilation as part of a properly functioning roofing system.
For this Northridge project, Ark Roofing & Construction upgraded the ventilation system so the attic could breathe more effectively rather than simply installing new shingles over the existing ventilation configuration.
Manufacturer-Backed Owens Corning Warranty Protection
Another significant benefit for this homeowner was the registered Owens Corning roofing warranty.
Owens Corning offers several levels of roofing warranty protection, with coverage depending on the roofing system installed, qualifying components, contractor certification, registration, and the specific warranty selected.
Owens Corning’s current extended warranty options can provide up to a 50-year TRU PROtection® period, depending on the qualifying roofing system and warranty. Its Preferred Protection Roofing System Limited Warranty can also provide 10 years of workmanship coverage. Complete terms, eligibility requirements, exclusions, and limitations are determined by the actual warranty issued for the project.
For this Northridge roof, the homeowner received the applicable registered manufacturer-backed warranty coverage associated with the installed Owens Corning roofing system.
That additional protection was an important part of choosing a complete roofing system rather than evaluating shingles on appearance alone.
Why Roofing System Components Matter
Homeowners naturally focus on shingle color and style because those are the portions of a roof they see every day.
But the performance of a roof depends on much more.
A properly constructed asphalt shingle roof can incorporate:
- Roofing shingles
- Synthetic underlayment
- Ice-and-water protection
- Valley protection
- Roof flashing
- Starter shingles
- Hip and ridge shingles
- Roof penetration details
- Intake and exhaust ventilation
Each component has a specific role.
The finished shingles protect the roof while establishing its appearance, but the layers and details underneath help manage water, airflow, and vulnerable transitions.
That system-based approach was particularly important on this Northridge home because the goal was not merely to make an old roof look new. The homeowner wanted a meaningful upgrade from the roofing system being removed.
A New Midnight Roof for This Northridge Home
The aerial view of the completed project shows how dramatically a roof replacement can change the appearance of a home.
The Owens Corning Midnight shingles create a deep, uniform roof color that contrasts beautifully with the light exterior walls while preserving the dimensional character the homeowner liked about the previous presidential-style roof.
More importantly, the improvement extends beneath the surface.
The home now has a newly installed roofing assembly incorporating upgraded synthetic underlayment, additional water protection at critical areas, improved attic ventilation, and registered manufacturer-backed warranty protection.
Instead of replacing worn shingles with another basic roof covering, this Northridge homeowner chose a complete roofing system designed around appearance, protection, ventilation, and long-term performance.
Our fair, hassle-free, and easy process is what sets us apart.
