While adding another layer of shingles might appear as an easy solution, is it really the best option for your roof? We’ll explore the advantages, disadvantages, building code concerns, and other alternatives.
Short-Term Savings and Long-Term Drawbacks
Benefits: Layering shingles can save time and money upfront by skipping the labor-intensive process of tearing off the existing layer. It’s a popular option for homeowners on tight budgets.
Cons: While cost-effective upfront, layering shingles can lead to several problems over time, including:
- The additional weight may cause structural issues, including sagging and possible damage to your roof.
- Layering shingles makes it harder to detect and address underlying issues such as leaks or rotting wood.
- Reduced lifespan of the new shingles due to heat retention and uneven application.
Things to Know About Building Codes When Layering Shingles
Before layering shingles, be sure to check local building codes, as most areas allow only two layers. Exceeding this can lead to insurance issues and safety concerns, so it’s crucial to consult professionals.
Why Weathercraft Recommends Against Layering Shingles
While adding a second layer might seem appealing, Weathercraft recommends avoiding this approach. Here’s 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.
- Enhanced Performance: By installing a single layer on a clean surface, new shingles adhere better and perform optimally over time.
- Improved Look: Single-layer roofs provide a cleaner, more professional appearance, as the shingles lie flatter and look more aesthetically pleasing.
Affordable Roofing Alternatives for Homeowners
For those on a budget, here are several alternatives to adding another layer of 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 offers affordable options to spread out roof replacement costs.
