Install Metal Roof Over Electric Riser

Align the first metal roofing panel so that it overlaps the edging by 1 2 to 3 4 of an inch and is square to the roof line.

Install metal roof over electric riser.

If you want to install steel over asphalt your best choice for installing metal roofing is to use a steel shingle system like the one shown instead of the more common and more expensive standing seam steel. Next use 1 inch nails to secure some metal edging to the perimeter of the roof. Be sure the larger edge is laid so that the small edge of the next panel will overlap it. Apply sealant to underside of base and secure base with roofing nails.

In a standing seam roof long single panels run vertically all the way from the eave to the ridge. Then cover the entire roof with a layer of insulation and secure it with a staple gun. Install the roofing screws vertically along each rib in the panel. Cut flashing opening to appropriate size for pipe.

You also need to add. When installing a metal roof over an existing roof insulate the spaces between the wood strips with rigid insulation to prevent condensation before installing the roofing. Before you install metal roofing repair any damage to the wood under the shingles.
