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.
Short-Term Savings and Long-Term Drawbacks
Pros: 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:
- Extra weight on your roof structure, potentially leading to sagging or 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
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.
- 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.
Affordable Roofing Alternatives for Homeowners
If cost is a concern, here are some alternatives to layering shingles:
- Targeted Repairs Instead of Full Replacement: Instead of redoing your entire roof, focus on repairing individual problem areas.
- Energy-Efficient Options: 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.
