Should You Add Another Layer of Shingles? The Benefits and Drawbacks

Short-Term Savings and Long-Term Drawbacks

Benefits: 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: While cost-effective upfront, layering shingles can lead to several problems over time, including:

• The extra weight can strain your roof’s structure, potentially causing sagging or other 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

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:

• 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: 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:

• Targeted Repairs Instead of Full Replacement: Instead of redoing your entire roof, focus on repairing individual problem areas.
• Consider Energy-Efficient Roofing: Choose shingles with better insulation to save on energy bills in the long run.
• Flexible Financing Plans: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
