Looking to add another layer of shingles to your roof? While it may seem like a simple fix, it’s important to weigh the pros and cons, check building codes, and explore expert alternatives.

Cost-Saving vs. Long-Term Risks

Pros: 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.

Drawbacks: 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.
  • Layering shingles makes it harder to detect and address underlying issues such as leaks or rotting wood.
  • The lifespan of the new shingles can be compromised by uneven installation and the heat retention from the old layer.

Important Building Code Regulations

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 Weathercraft Advises Against Multiple Layers

Although layering shingles may seem like an easy solution, Weathercraft suggests avoiding it for the following reasons:

  • Thorough Repairs: Removing the old shingles allows us to identify and repair hidden structural issues, ensuring long-lasting results.
  • Enhanced Performance: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
  • Enhanced Aesthetics: 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:

  • Targeted Repairs Instead of Full Replacement: Instead of redoing your entire roof, focus on repairing individual problem areas.
  • Energy-Efficient Options: Choose shingles with better insulation to save on energy bills in the long run.
  • Flexible Financing Plans: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
