1. Your Roof is Over 20 Years Old
Most standard asphalt shingles have a lifespan of 20–25 years. If your roof is approaching this age, it’s wise to plan for a replacement—even if there are no visible leaks.
Architectural shingles may last longer (30–50 years), but regular inspection is key once you pass the 20-year mark.
Tip: Can’t remember when your roof was installed? Check the permit history with your township or ask us to assess it for you.
2. Curling or Buckling Shingles
Shingles that are curling at the edges or buckling in the center are often a sign of:
-
Age-related deterioration
-
Heat damage
-
Poor attic ventilation
Curled shingles are more likely to blow off in high winds and allow moisture underneath, which can lead to leaks.
3. Missing or Broken Shingles
After a heavy storm or strong winds, inspect your roof from the ground for missing shingles. If you notice gaps or broken sections, your roof is vulnerable to water damage.
One or two missing shingles can be repaired, but if it becomes a recurring issue, it may be time for a full replacement.
4. Granules in Gutters
Asphalt shingles are coated with granules that help protect them from UV rays and weather. Over time, these granules shed and accumulate in your gutters.
Excessive granule loss leads to bald spots on your shingles, making them more susceptible to:
-
Cracking
-
Sun damage
-
Faster aging
If you see dark, sand-like debris in your gutters or at your downspouts, it’s a sign your shingles are nearing the end of their life.
5. Roof Looks Worn or Faded
A faded, patchy, or streaked roof not only hurts your home’s curb appeal—it may also signal worn-out materials.
Signs your roof’s aesthetic issues are more than cosmetic:
-
Algae streaks that don’t wash off
-
Uneven color due to missing granules
-
Discoloration from trapped moisture
These signs may indicate deeper problems beneath the surface.
6. You’re Dealing with Roof Leaks
Have you noticed:
-
Water stains on ceilings or walls?
-
Damp spots in the attic?
-
Mold growth or musty odors?
Leaks often start small and grow quietly. If left unchecked, they can lead to:
-
Rotting wood decking
-
Insulation damage
-
Structural issues
Leaks usually mean that shingles have failed or that flashing is compromised. In either case, a full inspection is needed.
7. Ice Dams Forming in Winter
New Jersey winters often lead to ice dams, especially on aging roofs. These form when snow melts on a warm roof and refreezes at the eaves, preventing proper drainage.
Ice dams signal poor roof insulation, aging materials, or clogged gutters. They also cause:
-
Shingle damage
-
Water seepage
-
Gutter detachment
If ice dams are a yearly issue, it might be time to upgrade your roof and attic ventilation system.
8. Shingles Are Cracked or Blistered
Cracks and surface blisters occur from:
-
Heat buildup
-
Poor attic airflow
-
Long-term sun exposure
Cracked shingles lose their waterproof seal and allow rain or snow to seep underneath.
This can lead to wood rot and early shingle failure. If you see widespread cracking, it’s safer to replace the roof.
9. Sagging Roof Deck
A sagging or dipping roof line could indicate:
-
Water damage in the underlayment
-
Rotted decking
-
Structural issues in rafters or trusses
This is a serious red flag and should be inspected immediately. Delaying action can lead to a full collapse in extreme cases.
10. Increased Energy Bills
If your heating and cooling costs are climbing and your insulation is in good shape, the roof may be the culprit.
Worn or poorly ventilated roofing traps heat or cold air, making your HVAC system work harder. Replacing the roof with a properly ventilated and reflective shingle system can dramatically improve energy efficiency.
Bonus Sign: You’re Planning to Sell Soon
If your home’s roof looks worn—even if it’s still functional—prospective buyers may see it as a negotiation point or walk away entirely.
A new roof:
-
Boosts curb appeal
-
Increases resale value
-
Provides peace of mind to buyers
Replacing asphalt shingles before selling can help you get top dollar and reduce time on the market.
