Welcome to our comprehensive guide on the topic of roofing versus reroofing. If you’re a homeowner or building owner, you may have encountered the dilemma of deciding whether to opt for a completely new roof or reroofing. In this article, we will explore the key factors to consider when making this decision, providing you with the necessary insights to make an informed choice.

Understanding Roofing

Before we delve into the comparison between roofing and reroofing, let’s first understand what each option entails.

Types of Roofing Materials

Roofing materials come in various types, each with its own unique characteristics and suitability for different environments. Here are a few commonly used materials:

  1. Asphalt Shingles: This is the most popular roofing material due to its affordability, durability, and ease of installation.
  2. Metal Roofing: Metal roofs offer exceptional longevity and can withstand harsh weather conditions. They are also energy-efficient and environmentally friendly.
  3. Clay Tiles: Known for their timeless aesthetic appeal and durability, clay tiles are a popular choice in regions with a Mediterranean or Spanish architectural style.
  4. Slate Roofing: If you’re seeking an elegant and long-lasting roofing option, slate tiles are an excellent choice. They are resistant to fire, mold, and insects.

Pros and Cons of Roofing

Roofing provides the advantage of a completely new roof installation. Here are some pros and cons to consider:


  • Enhanced structural integrity: With a new roof, you can ensure that your home or building has a strong and reliable structure overhead.
  • Customization options: Roofing allows you to choose from a wide range of materials, styles, and colors to match your preferences and the architectural design.
  • Warranty coverage: Many roofing materials come with warranties, providing you with peace of mind and protection against defects or damages.


  • Higher upfront cost: Installing a new roof involves more labor and materials, which translates to a higher initial investment.
  • Longer installation time: Roofing projects usually take longer to complete compared to reroofing, as it involves removing the existing roof and installing a new one.

Now that we have a basic understanding of roofing, let’s explore the concept of reroofing.

The Basics of Reroofing

Reroofing, also known as roof overlay or roof replacement, involves adding a new layer of shingles or roofing material over the existing roof. It is a less invasive and more cost-effective option compared to a complete roof replacement.

When is Reroofing Necessary?

Reroofing is typically considered when the existing roof is nearing the end of its lifespan but is still in relatively good condition. Here are a few situations where reroofing might be a suitable option:

  • Minor leaks or damage: If your roof has small leaks or localized damage, reroofing can be a practical solution.
  • Aging roof: If your roof is reaching the end of its expected lifespan, reroofing can help extend its longevity without the need for a complete replacement.
  • Cosmetic improvements: Reroofing allows you to update the appearance of your roof without the expense of a full replacement.

Benefits and Drawbacks of Reroofing

Before deciding on reroofing, it’s essential to consider both the advantages and limitations it presents.


  • Cost savings: Reroofing is generally more affordable than a complete replacement, as it eliminates the need for extensive labor and material costs associated with tearing off the existing roof.
  • Faster installation: Since the existing roof remains in place, reroofing projects are typically completed more quickly than full replacements.
  • Minimal disruption: Reroofing causes less disruption to your daily routine and reduces the risk of damage to your property during the construction process.


  • Limited lifespan extension: Reroofing can add a few more years to the lifespan of your roof, but it does not provide the same longevity as a completely new roof.
  • Hidden issues: While reroofing may cover up existing problems, such as underlying leaks or damaged decking, it does not address the root cause. It’s crucial to assess the condition of the underlying roof structure before deciding on reroofing.

Factors to Consider

Now that we have explored the basics of roofing and reroofing, let’s delve into the key factors you should consider when choosing between the two options.


Cost is often a significant factor in any home improvement decision. When it comes to roofing and reroofing, the cost will vary depending on several factors, including the size of your roof, the chosen materials, and the complexity of the project.

A completely new roof installation generally incurs higher costs due to the additional labor and materials required. On the other hand, reroofing offers a more budget-friendly alternative, as it eliminates the need for extensive tear-off and disposal expenses.


The expected lifespan of your roof is an important consideration. A completely new roof typically comes with a longer lifespan compared to reroofing. However, reroofing can still provide a significant extension to the lifespan of your existing roof.

When making a decision, it’s important to evaluate the current condition of your roof, its remaining lifespan, and the level of protection you desire.


The visual appeal of your roof plays a significant role in the overall appearance of your home or building. Both roofing and reroofing offer opportunities to enhance the aesthetics of your property.

Roofing allows for complete customization, enabling you to choose the materials, colors, and styles that best complement your architectural design. Reroofing, while limited to overlaying the existing roof, can still provide a refreshed appearance by adding new shingles or materials.

Energy Efficiency

Energy efficiency has become a crucial consideration for many homeowners. A properly insulated and energy-efficient roof can help reduce heating and cooling costs, providing long-term savings.

When deciding between roofing and reroofing, consider the energy efficiency features offered by different materials. Reflective coatings, insulation options, and proper ventilation can contribute to a more energy-efficient roof, resulting in a more comfortable indoor environment and potential energy savings.
