How to Install a Steel Roof Over Shingles

After years of weather, your shingles can begin to really show wear. Installing new shingles takes the time of removing them, putting down new tar paper underlay, and then putting down new shingles. A much easier alternative is installing steel roof panels right on top of the old shingles.

Things You'll Need

• Ring-shanked nails
• Hammer
• Steel roof panels
• Steel roof peak runners
• Protective eyewear
• Gloves
• Handheld metal shear
• Di-grinder
• Torch

Instructions

1. Position the first sheet of roof metal in a top corner of your roof. Make sure to lay the piece long ways so the ridges don't hold water and let water run off the roof instead.

2. 

   Nail down the steel roof panel with ring-shanked nails. Nail the center down in a low ridge of the panel. Space the nails every two feet. Before you nail the side down that will have a piece next to it, slide the next piece under the outer ridge of the panel you have partially nailed down. Nail this edge down now through the two panels.

3. Continue this pattern until the roof is completely covered. If the final sheet or corner sheet of steel roof panel doesn't fit, you can trim it down to size with a handheld metal shear, di-grinder, or torch.

4. Nail the steel roof peak runners into place at every peak of your roof. Hammer a nail in every foot on each side of the steel roof peak runner.
