Installing Steel Roofing Over Asphalt Shingles A Comprehensive Guide Installing steel roofing over existing asphalt shingles is a practical and efficient solution for homeowners looking to upgrade their roofing system. This method not only saves time and costs associated with removing the old roof but also provides added durability and longevity. In this article, we’ll explore the benefits, the installation process, and tips for ensuring a successful roofing project. Benefits of Installing Steel Roofing 1. Durability Steel roofing is known for its exceptional strength and resistance to extreme weather conditions. It can withstand heavy rain, strong winds, and hail, making it an excellent choice for areas prone to severe weather. 2. Energy Efficiency Steel roofs can reflect solar heat, which helps to keep homes cooler during the summer months. This reflection can potentially lower energy bills by reducing the need for air conditioning. 3. Longevity A properly installed steel roof can last 40 to 70 years, significantly longer than traditional asphalt shingles, which typically last around 15 to 30 years. 4. Environmentally Friendly Steel is a recyclable material, making steel roofing an environmentally sustainable choice. Additionally, it can be installed over old shingles, reducing waste sent to landfills. 5. Cost-Effective While the initial investment may be higher than asphalt shingles, the long-term savings on maintenance, replacements, and energy bills can make steel roofing a cost-effective option over time. Preparing for Installation Before installing steel roofing over asphalt shingles, homeowners should assess the condition of the existing roof. If the shingles are severely damaged or if there are signs of rot in the decking, it may be wise to repair or replace these areas before proceeding with the installation. 1. Permits and Regulations Check with local building codes and regulations to ensure that installing steel roofing over asphalt shingles is permissible . Some jurisdictions may require a permit for roofing work, while others may have specific guidelines that must be followed. 2. Materials Needed Gather all necessary materials and tools prior to starting the installation. This includes steel roofing panels, underlayment, fasteners, metal trim, and safety equipment such as harnesses and helmets. installing steel roofing over asphalt shingles 3. Safety First Ensure proper safety measures are taken during installation. This includes using harnesses when working on a steep roof and ensuring all tools are in good working condition. The Installation Process 1. Install Underlayment Begin by laying down a moisture barrier or underlayment over the shingles. This acts as an additional layer of protection against water infiltration. Ensure it is installed correctly, with overlaps to prevent moisture from seeping through. 2. Positioning the Panels Start installing the steel panels at the eaves, working your way up to the ridge. This method helps to ensure that water flows over the seams rather than into them. 3. Securing the Panels Use appropriate fasteners, typically screws, to secure each panel in place. Follow the manufacturer’s recommendations for spacing and type of fasteners to ensure a secure installation. 4. Installing Trim and Flashing After the panels are secured, install the metal trim and flashing around the edges, vents, and chimneys. This is crucial for preventing water leaks and ensuring a finished look. 5. Final Inspection Once installation is complete, conduct a thorough inspection of the roof to check for any loose panels or fasteners. It’s essential to ensure that everything is secure and that there are no potential leaks. Maintenance and Care Steel roofing requires minimal maintenance, but periodic inspections are still essential to ensure its longevity. Check for any signs of rust, damage, or loose panels, especially after severe weather events. Keeping gutters clear and maintaining the roof’s cleanliness will also aid in its durability. Conclusion Installing steel roofing over asphalt shingles is a smart investment for homeowners seeking a durable and long-lasting roofing solution. By following the proper installation methods and safety precautions, you can achieve a functional and aesthetically pleasing roof that enhances your home’s value and protects it for decades to come. With the right preparation and care, a steel roof can provide not only peace of mind but also significant savings in the long run.
