Every roof eventually crosses a line where the next repair costs more than it saves. The trick is recognizing that line before a leak finds your ceiling. Here are the seven signs we look for on inspections across Newark and northern New Jersey — most of them visible from the ground.

1. Shingles are curling, cupping or clawing

Shingle edges that curl upward or centers that lift mean the material itself has dried out and lost its seal. Once curling is widespread, wind gets underneath and the failures cascade — this is age, not damage, and it doesn't repair well.

2. Granules collecting in the gutters

The gritty surface on asphalt shingles is their UV armor. When you find sand-like granules accumulating in gutters and at downspout exits, the shingles are shedding their protection. Bald spots follow, then cracking.

3. Missing shingles after every storm

Losing a shingle in a violent storm happens. Losing shingles in ordinary wind means the adhesive seal strips have failed roof-wide — each individual patch fixes one symptom of a systemic problem.

4. The same leak keeps coming back

A leak that returns after multiple repairs usually means water is traveling under the shingle field from somewhere else. At that point you're paying repeatedly to chase a symptom. (One honest exception: sometimes the “roof leak” is actually failed flashing or a gutter problem — a proper inspection tells the difference.)

5. Daylight through the attic boards

Go into the attic on a bright day with the lights off. Points of daylight through the roof boards mean water can get through too. Small pinholes can be patched; visible gaps or sagging boards are structural.

6. Sagging rooflines

A ridge or roof plane that visibly dips means the decking — or worse, the framing — has absorbed moisture over time. This goes beyond re-shingling and needs attention promptly.

7. The roof is 20+ years old

Standard asphalt shingles in a New Jersey climate last 20–25 years. If your roof is in that window and showing any of the signs above, putting more repair money into it usually just delays the inevitable at a premium.

Repair or replace: the honest math

  • Repair makes sense when damage is isolated, the roof is under ~15 years old, and the rest of the shingle field is sound.
  • Replacement makes sense when damage is spread out, the roof is near end-of-life, or repairs are becoming an annual event.
