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: 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.
Disadvantages: 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.
Things to Know About Building Codes When Layering Shingles
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
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.
- Improved Look: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.
Alternatives for Budget-Conscious Homeowners
For those on a budget, here are several alternatives to adding another layer of shingles:
- Address Specific Problems Rather Than Replacing the Entire Roof: Instead of redoing your entire roof, focus on repairing individual problem areas.
- Opt for Energy-Saving Roofing Solutions: Opt for shingles designed to provide better insulation, reducing energy costs over time.
- Financing Plans: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
