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.
Weighing Cost-Savings Against Long-Term Risks
Benefits: 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 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.
- The lifespan of the new shingles can be compromised by uneven installation and the heat retention from the old 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 Weathercraft Advises Against Multiple Layers
Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:
- Comprehensive Repairs: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
- Superior Shingle Adhesion: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
- Sleeker Appearance: Single-layer installations lay flatter and look more polished.
Alternatives for Budget-Conscious Homeowners
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: 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.
