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.
Disadvantages: 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.
Important Building Code Regulations
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:
- Comprehensive 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: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
- Improved Look: Single-layer installations lay flatter and look more polished.
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: Address specific problem areas rather than redoing the entire roof.
- Consider Energy-Efficient Roofing: Energy-efficient shingles offer long-term savings by reducing heating and cooling costs.
- Affordable Financing Options: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
