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.

Cons: 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.
  • Difficulty identifying and fixing underlying problems, like 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

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 Advises Against Multiple Layers

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

  • In-Depth Repair Process: 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.
  • Enhanced Aesthetics: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.

Alternatives for Budget-Conscious Homeowners

For those on a budget, here are several alternatives to adding another layer of 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.
  • Flexible Financing Plans: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
