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.

Cost-Saving vs. Long-Term Risks

Advantages: Opting to layer shingles can be a quick, cost-effective solution, saving both time and money by avoiding the need to remove the old shingles. Many homeowners on a budget find this appealing.

Drawbacks: Over time, this approach can cause issues, including:

  • Extra weight on your roof structure, potentially leading to sagging or damage.
  • Difficulty identifying and fixing underlying problems, like leaks or rotting wood.
  • New shingles may have a shorter lifespan because of heat retention and uneven installation caused by the existing layer.

Building Code Considerations

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:

  • Comprehensive Repairs: Removing the old shingles allows us to identify and repair hidden structural issues, ensuring long-lasting results.
  • 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.

Other Budget-Friendly Roofing Options

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

  • Address Specific Problems Rather Than Replacing the Entire Roof: Instead of redoing your entire roof, focus on repairing individual problem areas.
  • Energy-Efficient Options: Opt for shingles designed to provide better insulation, reducing energy costs over time.
  • Financing Plans: Weathercraft offers affordable options to spread out roof replacement costs.
