How to Lay Metal Roofing

Metal roofs are durable, they hold up to the elements better, and they are tough, which is why they have been a favourite choice for homeowners throughout the years. It’s about the same if you are going to install a corrugated sheet or standing-seam panels, and it is all just about the same process. But how to lay metal roofing? Follow these steps by A2Z Roofing Edmonton to lay metal roofing properly.

1. Prepare the Roof Surface

Start by clearing out the old shingles, pulling the nails, and getting rid of all loose building debris. Inspect the roof deck and replace rotted wood. It ought to be flat, dry, and firm. Lay roofing underlay or felt on the whole deck. This is a moisture shield that guards against leaks and condensation, a necessary measure when doing any successful installation on a metal roof.

2. Install Edge Trim and Flashing

Apply drip edge trim to the lower ends of the roof so as to direct the rainwater. Next, install roof penetration flashing, including ventilation, chimney, skylights, and valleys. Flashing is used to keep water out of the building and seal weak areas.

3. Measure and Position the First Panel

Measure the distance between the ridges and the eave such that the panel can slightly extend past the edge of the roof (typically 1-2 inches). Install the first of the panels at one end of the roof, and make it quite square. It is important to get the first sheet in place; all panels that come after this sheet follow this position.

4. Fasten the Metal Panels

Secure covers by screwing them down with roofing screws and rubber washers. These washers will seal the holes and prevent leaks.

• Turn drive screws in a straight line (not angled).
• Separate them evenly as per the directions.
• Attach the ridges or flats based on the design of the panel.

Place the next panel over the last one by a single ridge or the suggested size of the ridge. Keep on placing cross panels across the roof until it is fully covered.

5. Install Ridge Caps and Final Sealing

After all the panels are in place, fasten down ridge caps to cover the top seam of the roof. Add foam strips (where required) to prevent windblown rain/vermin. Complete it by covering open joints and fasteners with a roof patch product to add some additional protection.
