When it comes to repairing a damaged roof, homeowners have a couple of options. Some choose to have another layer of shingles laid over their original roofing, while others opt for a full roof replacement. While adding more shingles is quicker and less labor-intensive, it’s not always the right choice—here’s why.

5 Reasons to Skip a Second Layer of Shingles

1. Weight Concerns

Roofing systems are built to bear some weight, including that of heavy snowfall. Yet, an aging roof won’t always be able to bear a heavy load. When you place an extra layer of shingles on top of existing ones, it puts significant strain on the structure. Factor in additional weight from future snow and issues like collapses become a concern. 

2. Difficult Repairs

Once you have another layer of shingles, structural issues become more difficult to detect. Problems like rot or mold, which can arise beneath the shingles, can hide under the thick upper surface and go unnoticed for too long. These issues can spread to other areas of your home if left unaddressed.

3. Poor Aesthetic

If visual impact is of any concern, a full roof replacement is the way to go. Multiple layers of shingles can have a bumpy, uneven surface. New shingles are often added over existing ones that are curling. The imperfections may still be visible through the new layer.

4. Insufficient Leak Protection

One of the most important reasons to forgo two layers of shingles is because this quick fix doesn’t involve the installation of any leak guards. When roofers perform a full replacement, they put structures in place such as water and ice barriers to prevent water from entering your home. If shingles are damaged, layers beneath may also be compromised, and simply adding another layer of shingles won’t fully block out water.

5. Added Costs

While it’s true that a complete re-roofing will cost more than simply adding shingles initially, it’s often the more economical choice over a long-term basis. With the potential leaks, weight issues, and other challenges which could arise from multiple layers of shingles, you’ll wind up needing a roof replacement eventually anyhow. Having the replacement done from the start will save you more over time.
