Can You Add Another Layer of Shingles? Pros and Cons Explained

Short-Term Savings and Long-Term Drawbacks

Benefits: Layering shingles can save time and money upfront by skipping the labor-intensive process of tearing off the existing layer. It’s a popular option for homeowners on tight budgets.

Disadvantages: However, there are several drawbacks to this method, such as:

• The extra weight can strain your roof’s structure, potentially causing sagging or other damage.
• Difficulty identifying and fixing underlying problems, like leaks or rotting wood.
• Reduced lifespan of the new shingles due to heat retention and uneven application.

Building Code Considerations

Before layering shingles, be sure to check local building codes, as most areas allow only two layers. Exceeding this can lead to insurance issues and safety concerns, so it’s crucial to consult professionals.

Why Weathercraft Advises Against Multiple Layers

While adding a second layer might seem appealing, Weathercraft recommends avoiding this approach. Here’s why:

• Comprehensive Repairs: Removing the old shingles allows us to identify and repair hidden structural issues, ensuring long-lasting results.
• Superior Shingle Adhesion: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
• Improved Look: A single layer of shingles provides a sleeker and more polished look compared to multiple layers.

Alternatives for Budget-Conscious Homeowners

If cost is a concern, here are some alternatives to layering shingles:

• Address Specific Problems Rather Than Replacing the Entire Roof: Address specific problem areas rather than redoing the entire roof.
• Energy-Efficient Options: Opt for shingles designed to provide better insulation, reducing energy costs over time.
• Flexible Financing Plans: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
