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: 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.
Cons: Over time, this approach can cause issues, including:
- The extra weight can strain your roof’s structure, potentially causing sagging or other damage.
- It becomes challenging to identify hidden problems, such as leaks or rotting, which may worsen over time.
- The lifespan of the new shingles can be compromised by uneven installation and the heat retention from the old layer.
Important Building Code Regulations
Most building codes allow only two layers of roofing materials. Adding more than this can lead to violations, insurance issues, and compromised safety. Before proceeding, always check local regulations and consult professionals to ensure compliance.
Why Weathercraft Recommends Against Layering Shingles
While adding a second layer might seem appealing, Weathercraft recommends avoiding this approach. Here’s why:
- Comprehensive Repairs: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
- Enhanced Performance: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
- Improved Look: A single layer of shingles provides a sleeker and more polished look compared to multiple layers.
Affordable Roofing Alternatives for Homeowners
If you’re looking for cost-effective roofing solutions, consider these alternatives to layering shingles:
- Address Specific Problems Rather Than Replacing the Entire Roof: Address specific problem areas rather than redoing the entire roof.
- Consider Energy-Efficient Roofing: Energy-efficient shingles offer long-term savings by reducing heating and cooling costs.
- Affordable Financing Options: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
