The Pros and Cons of Overlaying Vs. Complete Roof Replacement 

Table of Contents

When it comes to maintaining the integrity and functionality of your roof, there are various options to consider. Two popular options are overlaying and complete roof replacement. Both methods have their advantages and disadvantages, which we will discuss in this article. Whether you own a residential or commercial property in New York, it is important to understand the pros and cons of each approach before making a decision that suits your needs.

1. Roof Overlay

Overlaying, also known as a roof recover, involves placing new shingles or roofing material over the existing roof. This approach is typically chosen when the current roof is still in decent condition and only requires some enhancements.

Pros of Roof Overlay

– Cost-Effective: Overlaying is generally more cost-effective than a complete roof replacement since it involves less labor and materials.

– Time-Efficient: This method is quicker to complete compared to a full roof replacement, making it a convenient choice for those who require immediate repairs.

– Minimal Disruption: Since overlaying does not involve tearing off the existing roof, it causes less disruption to your daily activities or business operations.

Cons of Roof Overlay

– Reduced Lifespan: Overlaying only extends the life of the existing roof by a certain period. The new layer of shingles may not last as long as a completely new roof, resulting in the need for more frequent repairs or replacements in the future.

– Hidden Underlying Issues: While the existing roof may appear to be in good condition, overlaying may conceal underlying issues, such as water damage, mold, or decay. These problems may worsen over time if not properly addressed.

– Weight and Structural Concerns: Adding another layer of roofing material increases the weight on the roof, potentially compromising the structural integrity. It is crucial to consult with a professional to determine if your roof can handle an overlay.

2. Complete Roof Replacement

Complete roof replacement involves removing the existing roof down to the deck and installing a brand new one. This method is typically chosen when the current roof is severely damaged, has reached the end of its lifespan, or requires extensive repairs.

Pros of Complete Roof Replacement

– Improved Longevity: A completely new roof offers a longer lifespan compared to overlaying. It ensures maximum protection and durability for your property, reducing the need for frequent repairs.

– Addressing Underlying Issues: During the replacement process, any underlying issues can be identified and resolved, preventing future problems and potential additional costs.

– Flexibility in Material Choice: Roof replacement allows you to choose from a wide range of roofing materials, styles, and colors, enabling you to customize your roof to meet your aesthetic requirements.

Cons of Complete Roof Replacement

– Higher Cost: A complete roof replacement involves more labor, time, and materials, which makes it a pricier option compared to overlaying. However, it is worth considering the long-term benefits and reduced need for future repairs.

– Longer Installation Time: Roof replacement requires more time to complete compared to overlaying since it involves a more extensive process. This may cause inconvenience, especially for commercial property owners who need to temporarily halt their business operations.

– Disruption to Activities: Removing the existing roof and installing a new one can be disruptive, both in residential and commercial settings. However, the end result will provide a more reliable and durable roof for your property.


In conclusion, whether you choose to overlay or completely replace your roof, it is essential to consider the pros and cons of each method. Roof overlay offers cost and time efficiency, but it may not address underlying issues or provide long-lasting protection. On the other hand, complete roof replacement provides improved longevity, the opportunity to resolve underlying issues, and flexibility in material choice, but it comes at a higher cost and involves longer installation time.

To ensure the best decision for your residential or commercial property in New York, consult with a professional roofing contractor like Stellar Roofing.
