Asphalt Shingle Roof Installation Process
Initial Inspection and Permits
A professional roofer inspects your existing roof, checking for damage, deck integrity, and ventilation issues. Westwood Building Department requires permits for roof replacement. Your contractor should handle the application and fee—if they don't, find another contractor.
Removal of Old Roofing
Old shingles get torn off down to the roof deck, exposing the sheathing for inspection. Tear-off costs more than overlay but ensures longevity. Any rotten wood gets replaced, and debris goes into a dumpster—standard practice in Westwood.
Underlayment and Flashing Installation
Synthetic underlayment (like GAF Deck-Armor) gets laid over the deck for waterproofing. Ice and Water Shield goes along eaves and valleys per Westwood code (typically 6 feet up from eaves). Metal flashing around chimneys, vents, and skylights gets replaced and properly sealed to prevent leaks.
Shingle Installation
Installation follows a specific sequence:
1. Starter shingles go at eaves and rakes
2. Field shingles install from bottom up in staggered pattern
3. Each shingle receives 6 nails driven flush (not overdriven)
4. Ridge vents or hip vents provide attic ventilation
Proper ventilation prevents ice dams in Westwood winters.
Final Cleanup and Inspection
After installation, the crew cleans all debris and uses magnets to collect stray nails. A final inspection ensures code compliance, and the roofer provides a warranty certificate. Consider requesting a final inspection by the Westwood building inspector for peace of mind.
Cost of Asphalt Shingle Roof in Westwood
Factors Influencing Cost
**Roof size** — Measured in squares (100 sq ft each)
**Pitch** — Steep roofs cost more in labor
**Layers** — Tear-off versus overlay (if allowed)
**Shingle quality** — Three-tab versus architectural versus luxury
**Complexity** — Dormers, valleys, skylights add cost
**Permit fees** — Around $50–$100 in Westwood
**Labor rates** — Bergen County runs higher than national average
Average Cost Estimates
For a typical 1,500–2,000 sq ft home in Westwood:
**Three-tab shingles:** $5,000–$8,000
**Architectural shingles:** $7,000–$12,000
**Luxury shingles:** $10,000–$18,000
These prices include removal and disposal. Get at least three estimates, as actual quotes vary based on your specific roof.
Per-Square Pricing
**Three-tab:** $150–$250 per square installed
**Architectural:** $250–$400 per square installed
**Luxury:** $400–$600 per square installed
Overlay (if allowed) saves 10–20% but reduces lifespan. Most Westwood homes require tear-off for proper inspection and underlayment installation.
Durability and Maintenance of Asphalt Shingles
Expected Lifespan
**Three-tab:** 15–20 years
**Architectural:** 25–30 years
**Luxury:** 50+ years
Westwood's freeze-thaw cycles and humidity can reduce these numbers slightly. Proper ventilation and quality underlayment extend life.
Seasonal Maintenance Tips
**Spring:** Clean gutters and remove debris. Inspect for winter damage—cracked or curled shingles need replacement.
**Summer:** Trim overhanging branches that drop debris and create shade promoting moss growth.
**Fall:** Clear leaves from roof and gutters. Treat moss or algae with commercial cleaner. Avoid pressure washing—it damages shingles.
**Winter:** After heavy snow, use a roof rake to remove snow from eaves and prevent ice dams. Ensure attic ventilation remains unobstructed.
Signs of Damage to Watch For
**Missing, cracked, or curled shingles**
**Granule loss in gutters** — Indicates aging shingles
**Dark algae streaks**
**Rusted or damaged flashing**
**Light entering the attic** — Sign of deck damage
**Dents or tears after storms**
Address issues immediately. Small problems become expensive leaks and rot.
