An asphalt shingle roof is one of the most common and cost-effective roofing systems in New Jersey. With proper care and timely maintenance, an asphalt roof can last 20 to 30 years or more—but without regular upkeep, that lifespan may be cut short by half.
At All State Roofing & Chimney, we’ve seen firsthand how routine maintenance and smart preventive measures can help NJ homeowners avoid premature roof failure. In this guide, we’ll share the most effective ways to extend the lifespan of your asphalt roof in NJ—so you can protect your investment, improve energy efficiency, and save on costly repairs.

Why Asphalt Roofs Wear Out Prematurely in NJ
New Jersey’s weather creates unique challenges for roofs:
-
Heavy winter snow and ice dams can damage shingles and flashing
-
Spring rain and humidity promote algae and mold
-
Summer heat and UV rays cause drying, cracking, and granule loss
-
High winds and storms can lift or remove shingles
Fortunately, many of these issues are preventable with the right maintenance.
10 Ways to Extend the Life of Your Asphalt Roof in NJ
1. Schedule Regular Roof Inspections
Have your roof inspected at least once a year, and after any major storm. Early detection of wear, leaks, or damage allows for minor repairs before they escalate.
At All State Roofing & Chimney, we provide comprehensive roof inspections with detailed reports and maintenance recommendations.
2. Keep Gutters and Downspouts Clean
Clogged gutters trap water on your roof, leading to rot, mold, and shingle damage. Ensure gutters and downspouts are:
-
Cleared of leaves and debris every spring and fall
-
Free of standing water
-
Draining at least 3 feet away from your home’s foundation
Consider adding gutter guards to reduce seasonal buildup.
3. Trim Overhanging Tree Branches
Branches that hang over your roof can:
-
Drop debris that traps moisture
-
Scratch or gouge shingles during high winds
-
Provide a pathway for pests like squirrels or raccoons
Trim trees back at least 10 feet from your roof to protect shingles and promote airflow.
4. Remove Moss, Algae, and Debris
Moss and algae hold moisture on your roof and eat away at shingle surfaces. You can remove them by:
-
Spraying with a 50/50 mix of water and bleach
-
Gently brushing with a soft-bristle broom
-
Installing zinc or copper strips to prevent future growth
Avoid using a pressure washer—it can strip granules and damage your roof.
5. Maintain Attic Ventilation and Insulation
Your attic plays a crucial role in roof health. Poor ventilation causes excess heat in summer and moisture buildup in winter, which can:
-
Cause shingle blistering and rot
-
Lead to ice dams and mold
-
Increase heating and cooling bills
Ensure your attic has balanced intake (soffit) and exhaust (ridge or gable) vents, and check insulation levels yearly.
6. Replace Missing or Damaged Shingles Immediately
Missing shingles expose your underlayment and decking to moisture, leading to leaks and long-term water damage. After storms or high winds:
-
Inspect the roof visually from the ground or with binoculars
-
Look for loose, curled, or blown-off shingles
-
Contact a professional to make quick, proper repairs
Timely patchwork protects your roof’s integrity.
7. Monitor Flashing and Sealants
Flashing protects vulnerable areas like chimneys, vents, valleys, and skylights. Over time, flashing can rust or shift, and sealants can crack or wear down.
Check flashing annually and re-seal joints where necessary. Failing to maintain flashing is a leading cause of roof leaks in New Jersey homes.
8. Prevent and Manage Ice Dams
Ice dams form when snow melts on a warm roof and refreezes at the edges, blocking proper drainage. This forces water under shingles, damaging your roof deck.
To prevent ice dams:
-
Improve attic insulation and airflow
-
Seal attic bypasses (gaps that let warm air into the attic)
-
Install heated roof cables in problem areas if needed
9. Avoid Walking on the Roof
Walking on your roof wears down the surface, especially on hot days when shingles are more pliable. If you need roof access:
-
Use safety equipment and walk gently
-
Step on the lower center of shingles
-
Avoid stepping on ridges, hips, or valleys
Whenever possible, leave inspections and repairs to professionals.
10. Invest in Quality Repairs and Materials
If your roof requires repairs, don’t cut corners. Using cheap materials or inexperienced contractors can lead to more damage and reduced lifespan.

Warning Signs Your Roof Needs Attention
While maintenance can extend the life of your roof, it’s also important to recognize when your roof is aging or failing. Watch for:
-
Granules in gutters or bare patches on shingles
-
Water stains or mold in your attic or ceiling
-
Shingles that are cracked, curled, or missing
-
A sagging roofline
-
Frequent leaks or ice dams
If your asphalt roof is over 20 years old, it may be time to consider replacement.
