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
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: 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.
- 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
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: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
- Enhanced 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.
Affordable Roofing Alternatives for Homeowners
If cost is a concern, here are some alternatives to layering shingles:
- Repair Instead of Replace: Instead of redoing your entire roof, focus on repairing individual problem areas.
- Opt for Energy-Saving Roofing Solutions: Energy-efficient shingles offer long-term savings by reducing heating and cooling costs.
- Financing Plans: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
