• Metal Roofing Panels (corrugated, standing seam, or shingles)
• Underlayment (synthetic or felt)
• Metal Roofing Screws (with neoprene washers)
• Flashing (eave, valley, step, and ridge caps)
• Closure Strips (inside and outside foam closure strips)
• Butyl Tape (for sealing seams)
• Roofing Vent Boots (for sealing around roof penetrations)

Before starting your metal roof installation, it’s important to assess the roof’s structure. If you’re considering how to install metal roofing over shingles, ensure the shingles are in good condition and that the decking underneath is sturdy. This step is crucial to ensure your new metal roof will be properly supported. For new structures, such as sheds or commercial buildings, conduct the same inspection to confirm the foundation is strong and stable.

• Choose the Right Materials: Depending on the project, you may need corrugated metal roofing, standing seam metal roofing, or 5V crimp metal roofing. Be sure to select high-quality underlayment, flashing, and metal roofing screws for a lasting installation.
• Gather Tools and Safety Gear: Assemble essential tools like tin snips, a power drill, a tape measure, and chalk line. Don’t forget safety gear such as a harness, gloves, and a sturdy ladder to ensure safe working conditions.
• Check Local Building Codes: Review your local building codes to ensure that your project, whether it’s installing metal roofing on a house or a shed, complies with regulations. Obtain any necessary permits before beginning your installation.

Whether you’re installing corrugated metal roofing on a flat roof or a traditional pitched roof, the underlayment is vital for protecting your home from moisture and ensuring a long-lasting roof.

• Choose High-Quality Underlayment: For added durability and moisture resistance, use synthetic underlayment, especially if you’re also learning how to install insulation under metal roofing. This ensures the roof will stay protected for years.
• Lay It Down and Secure Properly: Start at the eaves and roll the underlayment horizontally across the roof. Overlap each row by 4-6 inches and secure it with roofing nails or staples, making sure it lays flat and wrinkle-free.
• Seal Edges and Seams: Apply roofing tape along all seams and edges to prevent moisture infiltration. Proper sealing is key for long-term protection and leak prevention.

The heart of the installation process involves positioning and securing the metal roofing panels. Proper alignment and fastening are critical for a durable, visually appealing roof.

• Measure, Cut, and Position Panels: Measure each roof section and cut the metal panels to fit. For projects involving how to install standing seam metal roofing, ensure the panels are aligned perfectly to avoid any gaps.
• Secure the Panels with Screws: Use metal roofing screws along the ribs of each panel, spacing them 12-18 inches apart. For projects like how to install screw-down metal roofing, make sure the screws are tight enough to seal the rubber washers but not so tight as to distort the panels.
• Overlap Panels and Trim for Vents or Chimneys: Overlap each panel by at least one ridge for a tight seal. If installing corrugated metal roofing on a shed, trim panels around roof penetrations like chimneys or vents, and apply flashing to ensure these areas are properly sealed.

After installation, it’s important to inspect the roof thoroughly to ensure everything is secure and watertight. Cleaning up the site and performing regular maintenance ensures the longevity of your new roof.

• Inspect for Loose Screws and Gaps: Carefully inspect the entire roof for any loose screws, gaps in the flashing, or misaligned panels. Tighten screws and adjust any panels to ensure the roof is sealed properly.
• Clean Up Debris and Tools: Make sure to remove all leftover roofing materials, debris, and tools. For larger projects like commercial metal roofing or installing metal roofing on a shed, proper cleanup is essential for both safety and appearance.
• Perform Regular Maintenance Checks: To ensure long-term performance, schedule regular maintenance checks. Clear debris from the roof, gutters, and downspouts, and inspect the roof for any signs of wear or damage.
