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
Pros: 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.
Cons: However, there are several drawbacks to this method, such as:
- Extra weight on your roof structure, potentially leading to sagging or damage.
- 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
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
Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:
- Comprehensive Repairs: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
- Better Performance: Starting with a clean slate ensures the new shingles adhere properly and last longer.
- Sleeker Appearance: Single-layer installations lay flatter and look more polished.
Alternatives for Budget-Conscious Homeowners
If cost is a concern, here are some 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: Choose shingles with better insulation to save on energy bills in the long run.
- Flexible Financing Plans: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
