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

Re-roofing is a less invasive process than roof replacement, so it may seem like a great way to get a new roof. However, the downside to re-roofing often outweighs the potential benefits. Let’s compare re-roofing vs. roof replacement to determine which option is right for your home.

Difference between Re-Roofing and Roof Replacement

With re-roofing, new shingles are applied over your existing shingles. With roof replacement, the old shingles are completely removed before the new shingles are installed. Re-roofing requires less labor and is thus less expensive, but the end results are not as reliable as roof replacement.

It’s also important to note that not all roofs can be re-roofed. It depends on the condition of the current roofing materials, how many layers of shingles are on the roof, what type of shingles you’re getting/covering, and many other factors. Don’t get too attached to the idea of re-roofing because it may not even be an option for your home.

Steps in Re-Roofing

If your roof only has one layer of shingles and those shingles are stable enough to roof over, re-roofing simply involves installing a new layer of shingles over the old. There isn’t much to do in terms of demolition because the new materials are going over the current layer. With this in mind, re-roofing does not offer the same repair options as roof replacement, which could make your roof prone to leaks in the future.

Steps in Roof Replacement

Roof replacement is a more extensive process that yields longer lasting results. The steps include:

  • Remove all existing shingles and inspect the roof for damage.
  • Replace rotten plywood and other hazards to create a reliable foundation for the new roof.
  • Add ice dam protection, as needed, and install asphalt paper to seal off the roof.
  • Install a new layer of shingles in the color and style of the homeowner’s choice.
  • Add flashing around chimneys and vents to protect against water infiltration.
  • Clean up all construction debris to leave the property looking its best.

The roof replacement process may vary from one property to the next based on the home’s specific needs. For instance, you may need new facia boards during your roof replacement, or you may decide to get new gutters when you get a new roof.
