Pros & Cons Of A Roof Overlay vs Roof Replacement

Understanding the pros and cons of a roof replacement vs a roof overlay is important before home or business owners make their decision. While both are good options for enhancing the integrity of your building, they have big differences in the approach and outcome. 


What is the main difference between a roof replacement vs a roof overlay? A roof overlay is the process of installing a new layer of shingles right over your current roofing materials without removing the old shingles. A roof replacement is the process of completely removing your roof shingles and replacing them with brand new ones.


Roof Replacement Pros:

  • This is a full upgrade to your roof system

  • Select brand new roofing materials

  • Increased durability & longer lifespan

  • Stronger against tough climate

  • Higher property & resale value


Roof Overlay Pros:

  • Quicker installation times 

  • Less labor time

  • Lower cost for installation

  • Easier to dispose of old roofing materials

  • Less risk of falling objects during the installation


The One Roof Replacement Con:

The only downside to a full roof replacement would be the cost and labor. Since our roofers would have to completely remove the old roof system, there is added time and cost to the waste removal process.


Roof Overlay Cons:

  • Possible long-term damage effects that may cost you more in the future

  • Adding extra weight to your pre-existing roof can stress the roof structure

  • Hard to identify structural problems to your roofing system

  • May lead to water damage due to compromised roof parts


Which One Do You Choose?

Going with a complete roof replacement rather than a roof overlay offers many long-term benefits. A roof replacement ensures all underlying issues are addressed, such as damaged decking or insulation, providing a sturdy foundation for the new roof. Additionally, it allows for improved insulation, better energy efficiency, and increased property value, making it a more cost-effective and durable solution in the long run.



While a roof overlay may seem like a good option with its quick installation and lower upfront costs, it often leads to long-term problems such as structural damage. Deciding to get a roof replacement is the best solution as it addresses the real underlying issues of your roof and can withstand harsh Chicagoland weather. By prioritizing things such as durability, efficiency, and property value, going with the full roof replacement will give business and homeowners the best quality roof they could get.
