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.
Short-Term Savings and Long-Term Drawbacks
Advantages: Opting to layer shingles can be a quick, cost-effective solution, saving both time and money by avoiding the need to remove the old shingles. Many homeowners on a budget find this appealing.
Drawbacks: Over time, this approach can cause issues, including:
- The additional weight may cause structural issues, including sagging and possible damage to your roof.
- It becomes challenging to identify hidden problems, such as leaks or rotting, which may worsen over time.
- New shingles may have a shorter lifespan because of heat retention and uneven installation caused by the existing layer.
Things to Know About Building Codes When Layering Shingles
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 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.
- Superior Shingle Adhesion: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
- Enhanced Aesthetics: Single-layer installations lay flatter and look more polished.
Affordable Roofing Alternatives for Homeowners
For those on a budget, here are several alternatives to adding another layer of shingles:
- Repair Instead of Replace: Address specific problem areas rather than redoing the entire roof.
- Energy-Efficient Options: Opt for shingles designed to provide better insulation, reducing energy costs over time.
- Affordable Financing Options: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
