Roof Repair or Replacement? How to Know.
Carpenters Touch, Livingston NJ
Mar 06, 2026
How do I know if I need a roof replacement or just a repair?
If damage is isolated, a repair may work. But widespread issues like sagging, leaks, or granule loss usually mean replacement is needed.
How long does a roof typically last?
Most asphalt shingle roofs last 20–30 years, depending on installation quality and weather conditions.
Are missing shingles always a big problem?
Yes. Missing shingles expose your roof to water damage and can lead to leaks if not addressed quickly.
What causes granule loss on shingles?
Granule loss is caused by aging, weather exposure, hail damage, and poor-quality materials.
Is moss or algae on a roof dangerous?
Yes. It traps moisture and accelerates roof deterioration, often indicating the roof is near the end of its life.
