Metal Roof Retrofits: Enhancing Your Roof with Efficiency and Durability 💪
Introduction
👉 Metal roofs are known for their long-lasting durability, energy efficiency, and aesthetic appeal. However, as time goes by, the need for updates and improvements arises. This is where metal roof retrofits come into play. In this article, we will delve into what a metal roof retrofit entails, the different types of retrofits available, and the benefits of opting for a metal roof overlay. We will also provide insights into the installation process, considerations for panel quality, and the support offered by industry experts, like Sheffield Metals, for retrofit projects. Let's dive in!
What is a Metal Roof Retrofit?
👉 Before we explore the advantages of metal roof overlays, let's first understand what a metal roof retrofit actually is. A metal roof retrofit involves making enhancements or modifications to an existing roof without completely demolishing the structure. In most cases, this is done with existing metal panel systems. There are two main types of retrofits: overlays and slope conversions.
Types of Metal Roof Retrofits
3.1 Overlay
👉 An overlay retrofit involves building on top of an existing roof with a new structure. This eliminates the need for tearing off the old roof entirely. By adding a new layer of metal roofing, you can enhance the durability and energy efficiency of your roof without the hassle and cost of a complete replacement.
3.2 Slope Conversion
👉 Slope conversion retrofits are typically used when dealing with flat roofs from past decades. These roofs, often found in schools and buildings with internal drains, are prone to leaks over time. The slope conversion retrofit involves adding a sloped truss frame to the existing flat roof. This not only allows for efficient water drainage but also offers architects the opportunity to introduce architectural flexibility into the design.
Benefits of Metal Roof Overlays
4.1 Cost Savings
👉 One of the key advantages of opting for a metal roof overlay is the cost-saving aspect. Tear-offs can be time-consuming, expensive, and might lead to additional structural issues. By simply building on top of the existing roof, you eliminate the need for extensive demolition and potential disruptions to the building's operations. The cost of material and labor is considerably reduced, resulting in significant savings.
4.2 Structural Integrity
👉 Metal roof overlays also address structural concerns that may arise during a tear-off. Exposed fastener roofs, often found on older buildings, are designed to be part of the structure. Removing these roofs and replacing them with standing seam metal roofs can create structural problems. By avoiding a tear-off, you prevent such issues and ensure the overall integrity of the building's structure.
4.3 Insulation Opportunities
👉 Another benefit of metal roof overlays is the opportunity to upgrade insulation. The void created between the old roof and the underside of the new roof allows for insulation to be added effectively and economically. This can significantly improve the energy efficiency of the building, leading to reduced heating and cooling costs.
4.4 Workman's Compensation
👉 From a workman's compensation standpoint, metal roof overlays provide a safer working environment. The solid platform created by the existing roof allows workers to move around more securely, reducing the risk of accidents and injuries. This aspect is particularly important when the building needs to remain functional during the retrofit process.
Installation Process
5.1 Framing and Platform Creation
👉 The installation process for metal roof overlays involves the creation of a new framing system on top of the existing roof. The sub-framing, consisting of punched-out sticks, is securely screwed into the existing purlins. In zones with uplift considerations, such as the corners and eaves, a deflection limiter is added for additional support. Once the framing is complete, a new roof is installed on the platform, following the same procedure as a new roof installation on a new building.
5.2 Panel Selection
👉 It is crucial to select the right panels for metal roof overlays that meet both uplift testing requirements and slope specifications. The assembly must pass the ASTM E1592 uplift test, which necessitates the use of structural panels. Snap lock panels are typically not suitable for such retrofit projects due to their limitations. Investing in high-quality structural panels is essential as it not only ensures the roof's durability but also reduces the need for additional framing, resulting in cost savings.
Considerations for Panel Quality
👉 When choosing panels for a metal roof overlay, it is essential to prioritize quality. Opting for inexpensive panels might seem cost-effective at first, but it can lead to significant problems down the line. Inferior panels can impact the entire framing system, necessitating additional intermediate frames to meet structural requirements. Investing in a good quality structural panel from reputable manufacturers like Sheffield Metals can save time, money, and hassle in the long run.
Slope and Water Penetration Requirements
👉 When planning a metal roof overlay, it is important to consider the slope and water penetration requirements of your project. While many panels are designed for slopes above two twelve, there are limitations for steeper slopes. Ensure that the selected panel can withstand the desired slope and provide adequate protection against water penetration. This will help maintain the building's integrity and prevent potential leaks or water damage.
Sheffield's Support for Retrofit Projects
👉 Sheffield Metals is committed to supporting retrofit projects by providing panel systems, engineering expertise, and testing capabilities. With a wide range of tested and warranted systems, Sheffield offers solutions tailored to the unique requirements of each retrofit project. Their industry knowledge and exceptional customer service ensure a smooth retrofitting process and reliable, long-lasting roofs.
Conclusion
👉 Metal roof retrofits, particularly overlays, offer numerous benefits such as cost savings, enhanced structural integrity, insulation opportunities, and improved workman's compensation safety. By opting for a retrofit over a tear-off, you can minimize disruptions, upgrade your roof's efficiency, and extend its lifespan. Ensure that you choose high-quality materials and work with reputable experts like Sheffield Metals to ensure a successful retrofit project. Embrace the durability and efficiency of metal roofing through retrofits and enjoy the long-term benefits it brings.
