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

Short-Term Savings and Long-Term Drawbacks

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.

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: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
• Superior Shingle Adhesion: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
• Sleeker Appearance: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.

Alternatives for Budget-Conscious Homeowners

For those on a budget, here are several alternatives to adding another layer of shingles:

• Repair Instead of Replace: 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.
• Affordable Financing Options: Weathercraft offers affordable options to spread out roof replacement costs.
