Advantages of Installing Metal Roofing Over Shingles with Dean Roofing Company
Longevity and Durability
Opting for a metal roof ensures a lifespan ranging from 40 to 70 years, contingent on material choice and maintenance. When the metal is installed over existing shingles, there’s an added benefit of enhanced insulation and protection. This dual-layer approach is one reason many homeowners and roofing companies in Clearwater choose it for its durability.
Cost-Efficiency
A significant advantage of overlaying a metal roof on shingles is the savings on removal and disposal expenses. Dean Roofing Company emphasizes this approach not only for its cost benefits but also for its reduced environmental impact, minimizing waste.
Enhanced Insulation
The existing shingles act as an added insulating layer beneath the metal. This structure can significantly boost energy efficiency, a major factor when considering the fluctuating weather in Florida.
Key Considerations Before Installation
Weight Concerns
While metal roofs are inherently lightweight, combining them with shingles can raise concerns about the total weight on a house’s structure. Hence, it’s crucial to ensure a comprehensive inspection before installation.
Building Codes and Regulations
Local building codes might restrict the number of permissible roof layers. Before making a decision, consulting with roofing contractors in Clearwater FL, like the seasoned professionals at Dean Roofing Company, is advised to ensure compliance.
Potential for Moisture Trapping
Layering a metal roof over shingles carries a risk of moisture entrapment, which can escalate to mold or wood rot issues. Utilizing a top-quality underlayment can mitigate these risks effectively.
Conclusion
The decision to install a metal roof over shingles is one influenced by various factors, from cost considerations to structural integrity.
