Winter Architectural Shingle Roof Replacement with New Plywood Decking in Westwood, NJ
Winter roof replacement in Westwood, NJ included new plywood decking, SecureGrip 30 synthetic underlayment, charcoal architectural shingles, new chimney flashing, and waterproofed roof penetrations across a steep-slope residential roof.
This scheduled residential roofing project took place in Westwood, Bergen County, during winter conditions. The medium-to-large home had multiple intersecting roof sections, hips, valleys, ridges, and chimney transitions. The existing roofing system had reached replacement condition, and deteriorated areas of the roof deck required new plywood before the replacement shingles could be installed.
Roof problems found in Westwood
The inspection identified an aging asphalt shingle system with vulnerable areas around the chimney, valleys, roof penetrations, and sections of deteriorated decking. Replacing only the visible shingles would not have addressed the underlying roof-deck concerns, so the project was planned as a complete roofing-system replacement with new plywood sheathing and renewed waterproofing details.
Work completed during the winter roof replacement
The installation was completed in multiple stages to manage the steep roof geometry and cold, snowy conditions. The work included:
- Removing the existing asphalt shingles and opening the roof deck for inspection.
- Removing deteriorated decking sections and installing new plywood sheathing.
- Installing SecureGrip 30 synthetic roofing underlayment over the new plywood substrate.
- Installing starter shingles, charcoal architectural asphalt shingles, and matching ridge-cap shingles.
- Shingling the intersecting roof sections, hips, valleys, and ridges for continuous weather coverage.
- Installing new metal flashing at the brick chimney.
- Flashing and sealing the plumbing vent penetration.
- Waterproofing roof-to-wall transitions and other vulnerable details with compatible membrane and sealant materials.
Roofing materials and appearance
The new roof uses charcoal or dark-gray architectural asphalt shingles over new plywood decking and SecureGrip 30 synthetic underlayment. Architectural shingles provide a dimensional finish and a more substantial appearance than basic three-tab shingles. New ridge-cap shingles and carefully finished valley and chimney details complete the system.
Working in snow and cold weather
Snow and cold temperatures added access and installation challenges, especially on the steep roof slopes. The project was completed in controlled stages so exposed areas could be covered and the roof assembly could be secured as work progressed. The finished photos show the completed charcoal roof across the main slopes, hips, valleys, ridge lines, chimney areas, and lower roof sections.
Project result
The old roofing system was fully replaced, and deteriorated decking was upgraded with new plywood. The home received a complete charcoal architectural shingle roof with new synthetic underlayment, ridge caps, chimney flashing, plumbing-vent flashing, and waterproofed transition areas. The final roof has straight shingle courses, clean ridge lines, and a continuous weather-resistant finish prepared for winter weather.

Westwood roof replacement FAQs
Why was a complete roof replacement recommended?
The existing roof had reached replacement condition, and the inspection found deteriorated decking and vulnerable areas around the chimney, valleys, and penetrations. A complete replacement addressed the roof covering and the layers beneath it together.
Was the roof decking replaced?
Yes. Deteriorated sections were removed and replaced with new plywood sheathing before the synthetic underlayment and architectural shingles were installed.
What underlayment was installed?
SecureGrip 30 synthetic roofing underlayment was installed over the new plywood roof deck as part of the replacement roofing system.
What type and color of shingles were installed?
Charcoal architectural asphalt shingles were installed with starter shingles and matching ridge-cap shingles. The finished roof has a dark-gray appearance.
How was the brick chimney handled?
The brick chimney received new metal flashing integrated with the replacement shingles and underlayment to improve water resistance at the roof-to-chimney transition.
How was the plumbing vent protected?
The plumbing vent penetration was properly flashed and sealed as part of the new roofing work. Roof-to-wall transition areas and other vulnerable details were also waterproofed.
Was this an emergency repair?
No. This was a scheduled full roof replacement completed in multiple installation stages during the winter.
Can a roof inspection identify deteriorated decking?
A professional roof inspection can identify visible signs of aging, water-intrusion risk, and areas that may require closer evaluation. When decking is exposed during a roof replacement, deteriorated sections can be replaced before the new shingle system is installed.
