💡 7-Step Guide to Install Metal Roofing

Installing a metal roof may seem like a daunting task, but breaking it down into manageable steps can make it much more manageable. Here are the seven steps to guide you through the installation of your new metal roof.

Prepare and Plan

Assess Your Roof: Before you start, carefully examine your existing roof to ensure its structural integrity. Measure its dimensions to calculate the amount of metal roofing material required.

Select the Right Materials: Choose from various metal roofing styles, such as standing seam, corrugated panels, or metal shingles, based on your preferences and needs. Ensure you have all necessary materials, including underlayment, fasteners, and flashing.

Gather Tools and Safety Equipment: Essential tools for metal roof installation include tin snips, a power drill with metal roofing screws, a tape measure, a chalk line, a ladder, safety harness, gloves, and roof jacks.

Check Local Building Codes: Ensure compliance with Marietta's building codes and regulations. Obtain any required permits before beginning the project.

Remove the Old Roofing

Remove Old Shingles: Use a roofing shovel to remove existing shingles and underlayment carefully, avoiding damage to the roof decking.

Inspect and Repair Decking: Inspect the roof decking for any damage after removing the old roofing. Replace any damaged sections to provide a solid foundation for the new metal roof.

Clean the Surface: Sweep the roof surface clean of debris, nails, and dust to ensure proper adhesion of the new underlayment and roofing materials.

Install the Underlayment

Select the Right Underlayment: Synthetic underlayment is recommended for its durability and moisture resistance.

Lay the Underlayment: Start at the eaves and roll out the underlayment horizontally, ensuring it lays flat. Overlap each row by 4-6 inches and secure it with roofing nails or staples.

Seal the Edges: Use roofing tape to seal the seams and edges of the underlayment for added protection against moisture.


Eave Flashing: Secure eave flashing along the roof's edge, overlapping the underlayment.

Valley Flashing: Lay valley flashing in the valleys and secure it with roofing nails.

Step Flashing: Install step flashing where the roof meets walls or chimneys to create a water-tight barrier.

Metal Panels

Measure and Cut Panels: Measure the length of each roof section and cut metal panels to size using tin snips or a metal shear.

Position the First Panel: Start at the bottom corner of the roof, ensuring the first panel overhangs the eave flashing by 1-2 inches and is square to the roof edge.

Secure the Panel: Use a power drill and metal roofing screws to secure the panel to the roof deck every 12-18 inches along the panel's ribs and at the eave and ridge.

Continue Installing Panels: Overlap each panel by at least one ridge and ensure proper alignment using a chalk line.

Trim and Secure Panels: Trim panels to fit around vents, chimneys, and other penetrations. Use flashing to seal these areas.

Install Ridge Caps and Trim

Install Ridge Caps: Position ridge caps over the peak of the roof, ensuring they overlap the top edges of the metal panels.

Secure Ridge Caps: Use metal roofing screws to secure ridge caps to the roof, penetrating the underlying panels.

Install Edge Trim: Secure edge trim along the gable ends of the roof for protection and a finished look.

Final Inspection and Cleanup

Inspect Your Work: Thoroughly inspect the new metal roof for loose screws, misaligned panels, or gaps in the flashing.

Clean Up: Remove debris, old roofing materials, and tools from the roof and surrounding area.

Perform Maintenance Checks: Regularly clear debris from the roof and inspect for damage or wear to ensure the longevity of your metal roof.
