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.
Cost-Saving vs. Long-Term Risks
Advantages: 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.
Drawbacks: However, there are several drawbacks to this method, such as:
- The additional weight may cause structural issues, including sagging and possible damage to your roof.
- 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.
Things to Know About Building Codes When Layering Shingles
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 Recommends Against Layering Shingles
Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:
- Thorough Repairs: A tear-off reveals hidden damage, allowing us to address structural issues effectively.
- Superior Shingle Adhesion: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
- Enhanced Aesthetics: A single layer of shingles provides a sleeker and more polished look compared to multiple layers.
Affordable Roofing Alternatives for Homeowners
If cost is a concern, here are some alternatives to layering shingles:
- Address Specific Problems Rather Than Replacing the Entire Roof: Address specific problem areas rather than redoing the entire roof.
- Opt for Energy-Saving Roofing Solutions: Opt for shingles designed to provide better insulation, reducing energy costs over time.
- Financing Plans: Weathercraft offers affordable options to spread out roof replacement costs.
