For homeowners, knowing when to replace your roof is an important part of maintaining a home. From cracks in shingles to leaks in the ceiling, knowing the telltale signs of when to replace your roof can end up saving you more in the long run. The South Jersey roofing experts at High Point Roofing suggest you examine the current condition of your roof before springing into action.

Here’s what to think about if you’re wondering when to replace your roof

How old is your roof?

On a case-by-case basis, a new roof will generally last 20 years. And if your roof has endured more than 20 years, and you suspect that it’s time for replacement, you may get by a couple more years with repairs. 

Take a look around

Has a neighbor on your block recently replaced their roof? Homes that are built within the same time period may show similar signs of wear and tear from exposure to seasonal weather. Sometimes knowing when to replace your roof is as simple as looking around your neighborhood.  

Seeing green

If you notice moss growing on parts of your roof, it’s not something you should ignore. According to experts at High Point Roofing, moss growth indicates moisture trapped under your shingles, which can do irreparable damage to your roof.   

State of shingles 

Gauging the current condition of shingles on your roof can be telling. Look for shingles that share the following characteristics for signs of when to replace your roof.

  • Shingles are cracked or balding
  • Edges are curling upward
  • Shingles are patchy or missing 

Leaky ceiling 

At the first sign of a ceiling leak, many homeowners conclude a roof replacement is in order. But knowing when to replace your roof and when repairs will do the job can be tricky to the untrained eye. While a leaky ceiling is certainly a sign of roofing failure, determining and repairing the source may buy you extra time.

It’s important to seek a professional’s help in determining the source, as moisture and leaks can lead to wood rot and mold growth which may cause even more destruction down the line. 


Mold growth can have devastating effects on your roof and the rest of your home if not immediately treated. From trapped moisture to poor ventilation, it can spread fast and quickly become a big problem for any homeowner facing roofing failure.
