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.
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.
Cons: While cost-effective upfront, layering shingles can lead to several problems over time, 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 Advises Against Multiple Layers
While adding a second layer might seem appealing, Weathercraft recommends avoiding this approach. Here’s 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.
- Superior Shingle Adhesion: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
- Sleeker Appearance: Single-layer installations lay flatter and look more polished.
Other Budget-Friendly Roofing Options
If you’re looking for cost-effective roofing solutions, consider these alternatives to layering shingles:
- Address Specific Problems Rather Than Replacing the Entire Roof: 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: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
