Understanding the Differences Between Reroofing and Roof Replacement

Deciding Between Reroofing and Full Roof Replacement

Choosing whether to reroof or replace your roof entirely can be a significant decision, affecting both the cost and the lifespan of your roof. Here’s a detailed comparison to help guide you through the decision-making process.

What is Reroofing?

Reroofing is the process of layering one set of new shingles over a set of existing shingles. This method can only be performed once, meaning if your home already has two layers of shingles, reroofing is not an option. It’s typically faster and less costly than a full roof replacement.

  • Pros: Cost-effective; quicker installation.
  • Cons: Shorter lifespan; cannot be done if there are already two layers of shingles; not suitable for significant damage.

What is Roof Replacement?

Roof replacement involves removing all existing shingles, repairing any damaged roof deck, and installing new underlayment and shingles. This method is more thorough and extends the life of your roof.

  • Pros: Addresses underlying damages; longer lifespan; increases property value.
  • Cons: More expensive; more time-consuming.

Key Considerations for Each Method

  1. Condition of Your Current Roof:

    • Reroofing: Suitable for roofs with minor wear and tear.
    • Replacement: Necessary for roofs with extensive damage, multiple layers of shingles, or significant water damage.

  2. Cost:

    • Reroofing: Generally less expensive due to less labor and material cost.
    • Replacement: More costly upfront but can be more cost-effective in the long run due to less frequent repairs.

  3. Longevity and Performance:

    • Reroofing: Can extend the life of your roof for up to 10-15 years.
    • Replacement: Can last 20 years or more, ensuring a better ROI and peace of mind.

  4. Building Codes and Regulations:

    • Ensure compliance with local building codes which may affect the feasibility of reroofing based on the number of existing roof layers.

When choosing between reroofing and a full roof replacement, consider the age of your current roof, the extent of any existing damage, and your budget. If you are unsure, consulting with a professional roofing contractor can provide clarity.
