With the increasing demand for durable and sustainable roofing solutions, a career in the roofing industry offers exciting opportunities. Due to its exceptional durability, longevity, and resistance to harsh weather conditions, steel roofing is a preferred choice. With this guide, we’ll walk you through how to install steel roofing over shingles, providing invaluable insights and tips for beginners. Let’s get started.
Why Choose Steel Roofing Over Shingles?
Steel roofing stands as a premier choice in the roofing industry for a plethora of compelling reasons. Installing steel roofing over existing shingles has many benefits, including enhanced durability and environmental sustainability.
Exceptional Durability
Steel roofing exhibits unparalleled durability, capable of withstanding the harshest of weather conditions, including heavy rain, snow, hail, and strong winds. Unlike traditional roofing materials such as asphalt shingles, steel roofing resists cracking, warping, and corrosion, ensuring longevity and minimal maintenance requirements.
Longevity and Lifespan
One of the most enticing features of steel roofing is its exceptional lifespan. With proper installation and maintenance, steel roofs can endure for decades, providing long-term protection and peace of mind for homeowners and businesses alike. This longevity translates to significant cost savings over time, as the need for frequent roof replacements is virtually eliminated.
Energy Efficiency
Steel roofing contributes to improved energy efficiency by reflecting solar heat and reducing the transfer of heat into the building’s interior. This thermal reflectivity helps regulate indoor temperatures, thereby reducing the reliance on heating and cooling systems and lowering energy consumption. Ultimately, this leads to lower utility bills and a more sustainable living or working environment.
Environmentally Sustainable
In an era marked by increasing environmental consciousness, steel roofing emerges as an ecologically sustainable roofing solution. Steel is highly recyclable, with a significant percentage of steel roofing materials being manufactured from recycled steel. Furthermore, steel roofs are often coated with reflective coatings that enhance their energy efficiency, further reducing their environmental footprint.
Versatility and Aesthetic Appeal
Steel roofing offers a diverse range of styles, colors, and finishes, allowing homeowners and businesses to customize their roofs to complement their architectural preferences and design aesthetics. Whether seeking a traditional, rustic look or a modern, sleek appearance, steel roofing provides endless design possibilities to suit any taste or style.
Fire Resistance
Steel roofing boasts inherent fire-resistant properties, providing an additional layer of protection against fire hazards. Unlike combustible roofing materials such as wood shingles or shakes, steel roofing does not contribute to the spread of fire, enhancing the safety and security of the building and its occupants.
Minimal Maintenance Requirements
Unlike traditional roofing materials that may require periodic maintenance and repairs, steel roofing demands minimal upkeep. Routine inspections and occasional cleaning are typically all that is needed to keep a steel roof in optimal condition, freeing homeowners and businesses from the burden of extensive maintenance tasks.
The decision to install steel roofing over existing shingles is rooted in pragmatism, sustainability, and long-term value. With steel roofing, homeowners and businesses can enjoy enduring protection, peace of mind, and a sustainable roofing solution for generations to come.
How to Install Steel Roofing Over Shingles
You will find the following step-by-step guide helpful in learning how to install steel roofing over shingles.
Step 1: Pre-Installation Preparation
Before starting any roofing project, prioritize safety by equipping yourself with the necessary protective gear, including gloves, safety goggles, and sturdy footwear. Additionally, use a harness and secure ladder to minimize the risk of accidents while working at heights.
Begin by thoroughly inspecting the existing shingles to ensure they are structurally sound and free from any damage or deterioration. Replace any damaged or worn-out shingles before proceeding with the installation to maintain the integrity of the new roof.
Ensure you have all the required materials and tools for the installation process. It includes steel roofing panels, roofing screws, a drill with screwdriver attachments, a chalk line, a metal cutting saw, underlayment, flashing, and trim pieces.
Step 2: Measurement and Preparation
Measure the dimensions of the roof accurately to determine the quantity of steel roofing panels needed for the project. Use a tape measure and chalk line to mark guidelines on the roof for proper alignment and placement of the panels.
Apply a high-quality underlayment over the existing shingles to provide an additional layer of protection against moisture and improve insulation. Ensure the underlayment is installed evenly and securely across the entire roof surface.
Step 3: Attaching Roofing Panels
Begin installing the steel roofing panels from the bottom edge of the roof, overlapping each panel to ensure proper water drainage. Use roofing screws to secure the panels in place, ensuring they are fastened securely to the underlying structure.
Maintain consistent alignment and overlap between adjacent panels to create a watertight seal and prevent water infiltration. Use a chalk line or straight edge to guide the placement of each panel and ensure they are installed in straight, parallel rows.
Step 4: Cutting and Trimming Panels
Use a metal cutting saw to trim the steel roofing panels as needed to fit around corners, edges, and roof penetrations such as vents and chimneys. Take precise measurements and use a straight edge to ensure clean and accurate cuts.
Step 5: Securing Flashing and Trim
Install flashing around roof penetrations such as vents, chimneys, and skylights to create a watertight seal and prevent water leakage. Secure the flashing in place using roofing screws and sealant to ensure it remains securely attached.
Use trim pieces to cover exposed edges and create a polished appearance for the roof. Install small pieces along the edges of the roof and around roof penetrations, ensuring they are securely fastened and provide a seamless transition between panels.
Step 6: Final Inspection and Finishing Touches
Once all panels, flashing, and trim pieces are installed, perform a comprehensive inspection of the roof to check for any loose screws, gaps, or imperfections. Make any necessary adjustments or repairs to ensure the roof is watertight and structurally sound.
