Adding a second layer of shingles might seem like a quick fix for roof issues, but is it the best choice for your home? Let’s break down the pros and cons, building code considerations, and 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.

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.
  • Layering shingles makes it harder to detect and address underlying issues such as 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

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: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
  • Improved Look: Single-layer installations lay flatter and look more polished.

Affordable Roofing Alternatives for Homeowners

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

  • Repair Instead of Replace: If only certain parts of your roof need attention, targeted repairs can be more affordable than full replacement.
  • Energy-Efficient Options: Choose shingles with better insulation to save on energy bills in the long run.
  • Affordable Financing Options: Weathercraft offers affordable options to spread out roof replacement costs.
