Asphalt shingles are the most common roofing material for New Jersey homes—and for good reason. They’re affordable, durable, and come in a wide range of styles and colors. But to get the full 20–30+ years of lifespan that asphalt roofs are known for, regular maintenance is essential.
At All State Roofing & Chimney, we know the weather in New Jersey can be tough on roofing systems. That’s why we’ve created this complete asphalt roof maintenance checklist to help homeowners avoid major problems and preserve their investment.

Why Maintain Your Asphalt Roof?
A well-maintained asphalt roof lasts longer, looks better, and resists damage from storms, leaks, and algae. Skipping routine care may lead to:
-
Premature shingle failure
-
Leaks and water damage
-
Costly emergency repairs
-
Voided manufacturer warranties
By following this annual roof maintenance checklist, you can protect your home and avoid thousands of dollars in potential damage.
Annual Asphalt Roof Maintenance Checklist for NJ Homeowners
We recommend reviewing this checklist twice a year—ideally in spring and fall—to prepare for the changing weather.
1. Inspect Shingles for Damage or Wear
Walk around your home and visually check the roof for:
-
Curling or buckling shingles
-
Cracked or missing shingles
-
Bald spots or granule loss
-
Dark patches or streaks
Use binoculars or a drone for a better view, or call a roofing professional for a safe, thorough inspection.
When to act: If you spot any damaged or missing shingles, schedule a repair immediately to prevent water infiltration.
2. Check Flashing Around Chimneys, Vents, and Skylights
Flashing is the metal or rubber seal installed around roof penetrations. It’s a common source of leaks if it becomes:
-
Bent or cracked
-
Pulled away from the surface
-
Rusty or corroded
Have a roofer re-seal or replace compromised flashing before it becomes a leak hazard.
3. Clean Gutters and Downspouts
Blocked gutters can cause water to back up onto your roof, leading to:
-
Rotted fascia boards
-
Ice dams in winter
-
Water damage to shingles and underlayment
Clear out leaves, twigs, and debris. Make sure downspouts are pointed away from the foundation.
Tip: Consider installing gutter guards to reduce buildup.
4. Remove Debris from the Roof Surface
Leaves, branches, and pine needles can trap moisture on your shingles and cause mold or algae growth.
Use a leaf blower or a soft broom (never a pressure washer) to clear the surface, especially after storms.
5. Trim Back Overhanging Tree Branches
Trees that touch or hang over your roof can:
-
Scratch and damage shingles
-
Drop debris onto the roof
-
Provide a pathway for squirrels or raccoons
Trim back any branches within 6–10 feet of the roof to prevent contact and encourage air circulation.
6. Look for Signs of Algae, Moss, or Mildew
In humid or shaded areas of NJ, algae and moss can grow on asphalt shingles. These growths:
-
Trap moisture
-
Reduce shingle lifespan
-
Create unsightly black streaks
Use a 50/50 mix of water and bleach or a specialized roof cleaner to treat algae. Never use harsh chemicals or power washers.
Pro Tip: Consider algae-resistant shingles for future replacements.
7. Check for Sagging or Soft Spots
From the ground, look for areas where the roofline sags. Soft or bouncy spots on the roof deck may indicate:
-
Water intrusion
-
Rotted decking
-
Structural problems
These require professional evaluation and repair.
8. Inspect Attic and Ceiling for Leaks
Inside your attic or top-floor ceilings, check for:
-
Water stains
-
Damp insulation
-
Mold or mildew
-
Visible daylight through roof boards
Catch these issues early to prevent costly water damage and mold remediation.
9. Confirm Proper Ventilation
Asphalt roofs need good airflow to prevent:
-
Heat buildup in summer
-
Ice dams in winter
-
Shingle degradation from trapped moisture
Make sure ridge vents, soffit vents, and attic fans are working properly and are not blocked.
10. Schedule a Professional Roof Inspection
Even if everything looks fine, a trained roofer can detect subtle problems that homeowners may miss.
We recommend a professional inspection once per year, especially after major storms or before winter.
