Transform your home’s exterior with the durability and sleek aesthetics of steel roofing. Installing steel over existing shingles is a practical and cost-effective solution that adds value to your property. While the process may seem daunting, it’s a rewarding project that can be completed with proper preparation and care. Whether you’re a seasoned DIYer or entrusting the task to professionals, these step-by-step instructions will guide you through the installation process, ensuring a successful and weathertight outcome.
Before embarking on the installation, it’s crucial to prepare the existing shingle roof. Inspect the surface for any damaged or loose shingles, and replace or repair them accordingly. Ensure the roof is free of debris and vegetation by cleaning it thoroughly. Next, install 1×4 purlins perpendicular to the roof trusses, spaced approximately 24 inches apart. These purlins will provide a solid foundation for the steel panels to be secured. Finally, apply a layer of underlayment over the purlins to protect the steel from moisture and condensation.
With the roof prepared, you can proceed with the steel panel installation. Start by aligning the first panel at the eaves, ensuring it overhangs the edge by the manufacturer’s specifications. Secure the panel with roofing screws every 12 inches along the purlins. Overlap the successive panels by the recommended amount and fasten them in the same manner. Continue this process until the entire roof is covered, ensuring the overlaps are staggered for added weather protection. Finally, install flashing around chimneys, vents, and other protrusions to prevent water leaks and ensure a watertight seal.
How To Install Steel Roofing Over Shingles
Installing steel roofing over shingles is a great way to improve the durability and longevity of your roof. Steel roofing is much more resistant to fire, wind, and hail than shingles, and it can also last for up to 50 years. If you’re considering installing steel roofing over shingles, here’s a step-by-step guide to help you get started.
Step 1: Prepare the roof
The first step is to prepare the roof for the new steel roofing. This involves removing any old shingles, nails, or other debris from the roof. You should also check the roof for any structural damage and make any necessary repairs.
Step 2: Install the underlayment
Once the roof is prepared, you need to install the underlayment. The underlayment is a layer of material that helps to protect the roof from moisture and ice. There are several different types of underlayment available, so be sure to choose one that is compatible with your steel roofing.
Step 3: Install the steel roofing
Once the underlayment is installed, you can start installing the steel roofing. The steel roofing is typically attached to the roof with screws or nails. Be sure to follow the manufacturer’s instructions for installing the steel roofing.
Step 4: Finish the roof
Once the steel roofing is installed, you need to finish the roof. This involves installing the flashing, ridge caps, and other trim. The flashing helps to prevent water from leaking into the roof, and the ridge caps help to protect the roof from the elements.
Installing steel roofing over shingles is a relatively simple process, but it’s important to follow the manufacturer’s instructions carefully. By following these steps, you can install a steel roof that will last for many years to come.
