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: 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.

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

Things to Know About Building Codes When Layering Shingles

Before layering shingles, be sure to check local building codes, as most areas allow only two layers. Exceeding this can lead to insurance issues and safety concerns, so it’s crucial to consult professionals.

Why We Advise Against Adding Another Layer of Shingles

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.
  • Superior Shingle Adhesion: Starting with a clean slate ensures the new shingles adhere properly and last longer.
  • 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.
  • Consider Energy-Efficient Roofing: Choose shingles with better insulation to save on energy bills in the long run.
  • Financing Plans: Weathercraft offers affordable options to spread out roof replacement costs.
