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.

Weighing Cost-Savings Against 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: Over time, this approach can cause issues, including:

  • 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.

Building Code Considerations

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 We Advise Against Adding Another Layer of Shingles

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

  • In-Depth Repair Process: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
  • Superior Shingle Adhesion: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
  • Sleeker Appearance: Single-layer installations lay flatter and look more polished.

Other Budget-Friendly Roofing Options

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

  • Repair Instead of Replace: 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: Weathercraft offers affordable options to spread out roof replacement costs.
