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.
Weighing Cost-Savings Against 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 extra weight can strain your roof’s structure, potentially causing sagging or other 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.
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 Recommends Against Layering Shingles
Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:
- In-Depth Repair Process: 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.
- Sleeker Appearance: A single layer of shingles provides a sleeker and more polished look compared to multiple layers.
Other Budget-Friendly Roofing Options
If cost is a concern, here are some alternatives to layering shingles:
- Repair Instead of Replace: Address specific problem areas rather than redoing the entire roof.
- Consider Energy-Efficient Roofing: Opt for shingles designed to provide better insulation, reducing energy costs over time.
- Flexible Financing Plans: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
