The Hidden Dangers of Reroofing: How Your New Roof Could Be Putting Your Home at Risk

The roof is one of the most important parts of your home. It protects you and your family from the elements and helps regulate the temperature inside your house. However, like any other part of your home, your roof has a finite lifespan, and eventually, it will need to be replaced. This is where reroofing comes in – a process in which a new layer of shingles is added on top of the existing roof. Reroofing might sound like a good idea, as it can be cheaper and quicker than a full roof replacement, but it can actually be harmful to your roof in the long run. In this blog post, we will discuss why reroofing is bad for your roof.


1. Reroofing can trap moisture: When you reroof, you are simply adding a new layer of shingles on top of the existing roof. This means that any moisture or condensation that was previously trapped in the old roof will still be there. Trapped moisture can lead to rot, mold, and even structural damage. Over time, the moisture can also affect the new layer of shingles and compromise their effectiveness.


2. Reroofing can hide underlying problems: Reroofing can be a temporary fix for an underlying roof problem. Adding a new layer of shingles on top of old, damaged, or worn shingles can hide the problem, but it won't fix it. Reroofing can also make it difficult to inspect the underlying roof for any structural issues or leaks.


3. Reroofing can shorten your roof’s lifespan: A new layer of shingles can add weight to your roof structure, and this extra weight can shorten your roof's lifespan. Over time, the added weight of the new shingles can put stress on the underlying roof structure, leading to premature failure or collapse.


4. Reroofing can reduce your home’s value: Reroofing can be a red flag for potential homebuyers. If a home has been reroofed, it may suggest that there is an underlying problem that has not been addressed properly. A reroofed roof may also have a shorter lifespan, which can detract from the value of the home.


5. Reroofing can be more expensive in the long run: While reroofing can be cheaper than a full roof replacement in the short term, it can end up costing you more in the long run. Reroofing will only delay the inevitable, and if you wait too long, you may end up needing a full roof replacement anyway. Plus, if your roof has any underlying problems that were not addressed, you may end up paying more for repairs in the future.


In conclusion, reroofing might seem like a good idea at first, but it can be harmful to your roof in the long run. Trapped moisture, hidden problems, shortened lifespan, reduced home value, and higher costs are just some of the reasons why reroofing can be a bad idea. If your roof needs to be replaced, it's better to do it right the first time and avoid the potential problems that can come with reroofing. By working with a professional roofing contractor, you can ensure that your roof is replaced properly and will provide you with the protection and security your home deserves.
