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

Weighing Cost-Savings Against Long-Term Risks

Pros: Adding a second layer of shingles can save on labor costs and time by bypassing the tear-off process. It's a commonly chosen option for those seeking budget-friendly roofing solutions.

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

• The additional weight may cause structural issues, including sagging and possible damage to your roof.
• Difficulty identifying and fixing underlying problems, like leaks or rotting wood.
• Reduced lifespan of the new shingles due to heat retention and uneven application.

Things to Know About Building Codes When Layering Shingles

Building codes typically limit the number of roofing layers to two. Exceeding this limit could result in legal violations, insurance complications, and safety risks. Always verify local codes and seek expert advice.

Why We Advise Against Adding Another Layer of Shingles

Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:

• Thorough Repairs: A tear-off reveals hidden damage, allowing us to address structural issues effectively.
• Better Performance: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
• Sleeker Appearance: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.

Affordable Roofing Alternatives for Homeowners

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

• Targeted Repairs Instead of Full Replacement: 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.
• Financing Plans: Weathercraft offers affordable options to spread out roof replacement costs.
