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: 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 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.
- 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 Advises Against Multiple Layers
Although layering shingles may seem like an easy solution, Weathercraft suggests avoiding it for the following reasons:
- 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: Starting with a clean slate ensures the new shingles adhere properly and last longer.
- Improved Look: 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:
- Address Specific Problems Rather Than Replacing the Entire Roof: If only certain parts of your roof need attention, targeted repairs can be more affordable than full replacement.
- Consider Energy-Efficient Roofing: Choose shingles with better insulation to save on energy bills in the long run.
- Affordable Financing Options: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
