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.
Cost-Saving vs. Long-Term Risks
Benefits: 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.
Cons: However, there are several drawbacks to this method, such as:
- The extra weight can strain your roof’s structure, potentially causing sagging or other 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.
Important Building Code Regulations
Most building codes allow only two layers of roofing materials. Adding more than this can lead to violations, insurance issues, and compromised safety. Before proceeding, always check local regulations and consult professionals to ensure compliance.
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:
- Thorough Repairs: Tearing off the existing shingles helps uncover any hidden damage, which can be repaired properly for better long-term roof performance.
- Better Performance: A clean surface allows for proper adhesion of new shingles, ensuring their durability and performance.
- Enhanced Aesthetics: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.
Other Budget-Friendly Roofing Options
If you’re looking for cost-effective roofing solutions, consider these alternatives to layering shingles:
- Address Specific Problems Rather Than Replacing the Entire Roof: If only certain parts of your roof need attention, targeted repairs can be more affordable than full replacement.
- Energy-Efficient Options: Energy-efficient shingles offer long-term savings by reducing heating and cooling costs.
- Flexible Financing Plans: Weathercraft provides financing solutions to help homeowners manage the cost of roof replacement.
