Is Adding a Second Layer of Shingles a Good Idea? Pros and Cons Unpacked

Short-Term Savings and Long-Term Drawbacks

Advantages: 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: Over time, this approach can cause issues, including:

• 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.

Building Code Considerations

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 We Advise Against Adding Another Layer of Shingles

Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:

• In-Depth Repair Process: Removing the old shingles allows us to identify and repair hidden structural issues, ensuring long-lasting results.
• Better Performance: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
• Enhanced Aesthetics: Single-layer installations lay flatter and look more polished.

Other Budget-Friendly Roofing Options

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.
• Financing Plans: If budget is a concern, Weathercraft offers flexible financing options to help manage roof replacement expenses.
