Your roof protects your home from the elements, but it doesn't last forever. Westwood's harsh weather—hot summers, cold winters, and frequent storms—takes a toll on roofing materials. Recognizing when to replace your roof prevents costly interior damage and keeps your family safe.
Here are 10 signs it's time for a new roof.
1. Your Roof Is Old
Typical Roof Lifespan in Westwood's Climate
Asphalt shingle roofs, the most common type in Westwood, typically last 20–25 years. However, the area's extreme temperature fluctuations and frequent storms accelerate wear. If your roof is approaching or exceeding this age, replacement is likely necessary.
Other materials offer greater longevity—slate and metal roofs can last 50+ years—but all roofing types require regular inspection regardless of material.
How to Find the Age of Your Roof
Check your home inspection report from purchase, contact a local roofer for their assessment, or look for permit records at the Westwood building department. Knowing your roof's age helps you plan proactively for replacement.
2. Missing or Damaged Shingles After Storms
Impact of Nor'easters and Hailstorms
Westwood regularly experiences Nor'easters and hailstorms. High winds can tear shingles completely off, while hail creates cracks or dents. Missing shingles expose the underlayment, creating direct pathways for water infiltration. Widespread damage following severe weather often signals the need for full replacement.
Inspecting After Severe Weather
Look for shingles scattered in your yard or gutters. From ground level, scan the roof for bare spots, visible cracks, or tears. When damage covers a large area, complete replacement is more cost-effective than piecemeal repairs.
3. Granule Loss in Gutters and Downspouts
Signs of Shingle Wear
Asphalt shingles are coated with protective granules that shield against UV rays and weathering. As shingles age, these granules loosen and wash into gutters during rain. Excessive granule loss indicates the shingles are deteriorating and losing their ability to protect your home.
Checking Your Gutters for Granules
After rainstorms, inspect downspout outlets and gutters for granule accumulation—it resembles coarse, dark sand. Also look for bald spots on shingles where the underlying asphalt is exposed. Significant granule loss means your roof needs replacement soon.
4. Leaks and Water Stains on Ceilings or Walls

Identifying Active Leaks
Water stains on ceilings or walls clearly indicate roof failure. During rainfall, check interior spaces for drips or wet spots. Active leaks typically signal widespread damage, particularly in older roofs.
Stains as a Long-Term Issue
Even without visible dripping, stains reveal past leaks or ongoing moisture penetration. This creates conditions for mold growth and structural rot. Multiple stain locations throughout your home indicate systemic failure requiring full replacement.
5. A Sagging Roof Deck or Roofline
Structural Concerns
A sagging roof represents a serious structural issue. It indicates the decking (wood beneath shingles) is rotting or the roof framing is compromised. Left unaddressed, this deterioration can lead to partial or complete collapse.
When to Call a Professional Immediately
If you notice depressions, low spots, or dips in the roofline, contact a licensed roofer immediately. This constitutes a safety hazard requiring urgent attention. Repairs typically involve replacing both the damaged decking and all roofing materials.
6. Curling, Buckling, or Blistering Shingles
Causes of Curling and Buckling
Curling shingles (edges turning upward) or buckling (shingles lifting from the surface) indicate advanced age or inadequate attic ventilation. Heat and moisture trapped in the attic cause these deformations, rendering shingles ineffective at shedding water.
Blistering and Its Implications
Blistering manifests as small bubbles on shingle surfaces, caused by moisture beneath the shingles vaporizing from heat. When these blisters rupture, they leave exposed areas vulnerable to leaks. Widespread curling, buckling, or blistering indicates systemic shingle failure requiring full roof replacement.
7. Daylight Visible from the Attic
Enter your attic during daylight hours and turn off all lights. If you see sunlight penetrating through the roof boards, you have gaps or holes in your roof system. These openings allow water infiltration and pest entry, indicating your roof is no longer watertight and requires replacement.
8. High Energy Bills
A failing roof compromises your home's thermal envelope. Sudden spikes in heating or cooling costs may indicate your roof is allowing conditioned air to escape. Damaged or missing shingles, combined with compromised underlayment, reduce the roof's ability to regulate interior temperature. A new roof restores energy efficiency and lowers utility expenses.
9. Moss or Algae Growth
While moss and algae often appear purely cosmetic, they can indicate moisture retention problems. Moss holds water against shingles, accelerating decay and shortening roof lifespan. Westwood's humid climate promotes this growth. If moss coverage is extensive and your shingles are also aging, replacement should be considered rather than simple cleaning.
10. Multiple Repairs Needed
If you're scheduling roof repairs every few months for recurring leaks or missing shingles, complete replacement becomes more economical. Constant patch jobs accumulate costs quickly without addressing underlying deterioration. A new roof provides long-term protection and peace of mind.
Frequently Asked Questions
- How long does a typical roof last in Westwood, NJ?
- Asphalt shingle roofs typically last 20–25 years in Westwood, depending on maintenance and weather exposure. Premium materials like slate or metal can exceed 50 years with proper care.
- What are the earliest signs of roof damage to look for?
- Early warning signs include missing or curled shingles, granules accumulating in gutters, interior water stains, and daylight visible from the attic. Catching these early prevents more extensive and costly damage.
- Can I repair a leaking roof, or do I need a full replacement?
- Isolated damage from a recent incident can often be repaired. However, if your roof is old or exhibits widespread problems across multiple areas, full replacement is more cost-effective and provides better long-term protection.
- How much does a new roof cost in Westwood, NJ?
- Costs vary based on home size, materials selected, and project complexity. A new asphalt shingle roof for a standard Westwood home typically ranges from $8,000 to $15,000. Premium materials increase this investment.
- Is it normal to have minor leaks after a heavy storm?
- No. Any leak indicates damage requiring attention. Even minor leaks can worsen rapidly, leading to interior damage and mold growth. Always inspect your roof after severe weather and consult a professional roofer if you discover any water infiltration.
