Re-Roofing vs. Roof Replacement: What’s the Difference?

With your roof reaching the end of its life, you’re wondering if you should have it replaced. What you may not realize is that you actually have several options. You could pay for a full roof replacement, or you could hire a roofing contractor to re-roof your home.

What’s the difference between roof replacement and re-roofing? Let’s take a look!

What Is Re-Roofing?

Re-roofing involves layering new shingles onto the existing shingles of your roof. Because the initial layer of shingles is not torn off, the process is quicker and less expensive than replacing the entire roofing system. Re-roofing can be done only once, so if you already have two layers of roofing material, then this process is not an option for your home.

How Is Roof Replacement Different?

While replacing your roof, the roofing contractors will tear everything off down to the deck. Then, they will secure new felt and shingles to the house. Since everything is stripped away, it does not matter how many layers of shingles you have on your roof as it does with a re-roofing.

When Re-Roofing Is a Good Idea

Your contractor may suggest a re-roofing if your roof is nearing 15 years of age but is still in good shape. You can also have re-roofing done when there are only minor leaks or signs of wear and no water damage, soggy or missing asphalt shingles, or mildew growth. The extra layer of shingles can protect the existing roof from harsh weather conditions and strong winds. It’s a cost-effective solution to extend the life of your roofing system.

When You Should Choose a Roof Replacement

How do you know if re-roofing isn’t an option for you? There are a few situations where re-roofing is not the best choice. You will know you need a roof replacement over re-roofing when:

  • Your roof already has two layers of shingles.
  • The roof decking is rotting or sagging.
  • Only a portion of your roof needs to be done (a partial re-roofing can make your roof look uneven).
  • The roof shingles are damaged or cracked.
  • The roof’s flashing is damaged.
  • There is rot or moss buildup on the roof.
  • The entire roof is in poor condition.

Your roofing contractor will be able to examine your roof and determine if you need a roof overhaul. During an initial consultation, they can also provide you with an estimate of roof replacement costs in NJ, so you know how to plan for the project.
