While adding another layer of shingles might appear as an easy solution, is it really the best option for your roof? We’ll explore the advantages, disadvantages, building code concerns, and other alternatives.

Short-Term Savings and Long-Term Drawbacks

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.

Cons: 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.
  • It becomes challenging to identify hidden problems, such as leaks or rotting, which may worsen over time.
  • New shingles may have a shorter lifespan because of heat retention and uneven installation caused by the existing 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 Weathercraft Advises Against Multiple Layers

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

  • In-Depth Repair Process: A tear-off reveals hidden damage, allowing us to address structural issues effectively.
  • Enhanced Performance: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
  • Sleeker Appearance: Single-layer installations lay flatter and look more polished.

Affordable Roofing Alternatives for Homeowners

If you’re looking for cost-effective roofing solutions, consider these alternatives to layering shingles:

  • Targeted Repairs Instead of Full Replacement: If only certain parts of your roof need attention, targeted repairs can be more affordable than full replacement.
  • Consider Energy-Efficient Roofing: Opt for shingles designed to provide better insulation, reducing energy costs over time.
  • Affordable Financing Options: Weathercraft offers affordable options to spread out roof replacement costs.
