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

Advantages: 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.
  • Layering shingles makes it harder to detect and address underlying issues such as leaks or rotting wood.
  • 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

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

  • Thorough Repairs: Removing the old shingles allows us to identify and repair hidden structural issues, ensuring long-lasting results.
  • Superior Shingle Adhesion: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
  • Enhanced Aesthetics: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.

Affordable Roofing Alternatives for Homeowners

If cost is a concern, here are some alternatives to layering shingles:

  • Address Specific Problems Rather Than Replacing the Entire Roof: Address specific problem areas rather than redoing the entire roof.
  • Energy-Efficient Options: Energy-efficient shingles offer long-term savings by reducing heating and cooling costs.
  • Financing Plans: Weathercraft offers affordable options to spread out roof replacement costs.
