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

Weighing Cost-Savings Against Long-Term Risks

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.

Disadvantages: Over time, this approach can cause issues, 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.

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 We Advise Against Adding Another Layer of Shingles
