Reroofing Vs. Roof Replacement: What’s Better?

difference between reroofing and roof replacement

Is your roof reaching the end of its lifespan? If your roof shows signs of deterioration or is approaching the end of its guarantee, you may be questioning if it is time for a change. If it’s in good shape, you may reroof it instead of tearing it off and setting up a new one.

If your roof is made of tiles or a durable industrial covering, you could put a second layer right on top of the present one. It will give your roof some extra years for a small amount of the expense of a complete rebuild. There are a few options available – you just need to know which one is most suitable for your situation.

What Is Reroofing?

Reroofing is an option in contrast to stripping and rebuilding the entire roof. An additional layer of tiles is put on top of the original roof. While it’s not always recommended, it can lead to significant savings on replacement expenses. There is less work and time invested because the current top does not have to be removed. The procedure is also known as “recovering” because the old roof is covered with an extra layer.

To get an idea of how much you’ll cut costs on materials when reroofing, think about how many layers make up your roof. Flat (pitch below 10°) and low-pitched roofs (pitch between 10° and 35°) are often formed by three layers:

  • All roofs require a minimum of one layer of weatherproofing to prevent leakage. In addition, locations with a harsh climate should also have an ice-protective shield.
  • The second layer maintains the roof’s resilience, puncture protection, and overall strength.
  • The last layer serves to protect the other two layers from the weather and the sunlight. The top layer could also bring a few additional advantages, like protection against fire or eco solar reflective cover.

Commercial Roofs

When it comes to commercial pitched roofs, there are usually four layers. After the foundation (traditionally made of plywood) and the waterproof layer come two different coatings:

  • A smooth felt overlay keeps the water from going under the tiles and allows them to fit into place and lay flat.
  • The visible top layer of your roof is made up of asphalt tiles, metal panels, or wood shingles. They give both architectural beauty and protection. A fifth layer, known as a ridge cap, is added to asphalt shingles.

Reroofing pays off financially because most layers remain stable. You do not replace the entire roof. Instead, you trust the building’s existing and intact layers to offer foundation and security. As these materials are reused, reroofing provides considerable cost savings. Do not worry – your structure is secured because these protective layers remain unimpaired during the roof works. If you choose a reputable roofing company, you’ll have nothing to worry about for a long time.

Advantages:

  • It is a more cost-effective method of roof restoration.
  • It just adds another layer of tiles on top of the one you already have.
  • You don’t need to put in much effort, resources, or a significant amount of time.

Disadvantages:

  • You cannot add more layers if you’ve reached the maximum (which is usually two).
  • If you have metal panels, you will not be able to reroof.
  • You can’t get a good look at the situation under the existing tiles.
  • It may not survive as long as a complete roof replacement.

What Is Roof Replacement?

Rather than merely suppressing damage, a complete replacement will solve all of your roof’s issues. If your roof has signs of severe deterioration, your construction company will need to fix your roof deck to avoid additional harm. Water can leak down the walls through holes in the foundation, causing drywall and floor problems. This type of damage can be costly to fix. While replacing your roof is an expensive undertaking, it will eventually save you money because it helps you detect early symptoms of drooping and decay on the deck due to water intrusion. As a result, a complete roof replacement will include complete roof leak repair.

Your new roof will last between 10 and 50 years, depending on your material choice. And since the same material limitations do not bind it as reroofing, you have all the freedom of that choice.

Advantages:

  • You can spot and deal with all of the concerns regarding the state of your roof.
  • It usually saves money in the long term.
  • The roof will stand longer.

Disadvantages:

  • It’s a significant investment.
  • Roof replacement includes additional work, time, and resources.

Summary

If your roof is crumbling and it’s time to replace it, you should start looking for the best bargain. Reroofing is frequently presented as a less expensive alternative to a complete roof replacement, which could theoretically save you cash. But, reroofing is not for everyone. Understanding the difference between the two and when one is preferable to the other can assist you in making the right strategy for your house.
