Adding a second layer of shingles might seem like a quick fix for roof issues, but is it the best choice for your home? Let’s break down the pros and cons, building code considerations, and expert alternatives.
Short-Term Savings and Long-Term Drawbacks
Advantages: Adding a second layer of shingles can save on labor costs and time by bypassing the tear-off process. It's a commonly chosen option for those seeking budget-friendly roofing solutions.
Disadvantages: However, there are several drawbacks to this method, such as:
- Extra weight on your roof structure, potentially leading to sagging or damage.
- Layering shingles makes it harder to detect and address underlying issues such as 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 Weathercraft Advises Against Multiple Layers
Despite the initial appeal, Weathercraft advises against adding another layer of shingles. Here are the reasons why:
- Thorough Repairs: A tear-off reveals hidden damage, allowing us to address structural issues effectively.
- Better Performance: 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.
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.
- Affordable Financing Options: Weathercraft offers affordable options to spread out roof replacement costs.
