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

Weighing Cost-Savings Against Long-Term Risks

Benefits: 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.

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

• Extra weight on your roof structure, potentially leading to sagging or damage.
• It becomes challenging to identify hidden problems, such as leaks or rotting, which may worsen over time.
• The lifespan of the new shingles can be compromised by uneven installation and the heat retention from the old layer.

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

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

• In-Depth Repair Process: Removing the old shingles allows us to identify and repair hidden structural issues, ensuring long-lasting results.
• Enhanced Performance: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
• Improved Look: Single-layer installations lay flatter and look more polished.

Affordable Roofing Alternatives for Homeowners

For those on a budget, here are several alternatives to adding another layer of shingles:

• Address Specific Problems Rather Than Replacing the Entire Roof: Address specific problem areas rather than redoing the entire roof.
• Opt for Energy-Saving Roofing Solutions: Choose shingles with better insulation to save on energy bills in the long run.
• Flexible Financing Plans: Weathercraft offers affordable options to spread out roof replacement costs.
