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

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: While cost-effective upfront, layering shingles can lead to several problems over time, including:

  • 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.
  • Reduced lifespan of the new shingles due to heat retention and uneven application.

Things to Know About Building Codes When Layering Shingles

Most building codes allow only two layers of roofing materials. Adding more than this can lead to violations, insurance issues, and compromised safety. Before proceeding, always check local regulations and consult professionals to ensure compliance.

Why Weathercraft Recommends Against Layering Shingles

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

  • Comprehensive Repairs: 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.
  • Enhanced Aesthetics: Single-layer installations lay flatter and look more polished.

Alternatives for Budget-Conscious 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: 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.
