This video shows how to install standing seam panels when hemming the eave and rake.
How to install standing seam metal roof panels.
There are two main reasons.
A typical standing seam panel can be approximately 12 16 and 19.
Allow each consecutive course to overlap the previous one by at least four to six inches.
Start the installation of the underlayment at the intersection of an eave and a gable end and then roll it out parallel to the eave end.
The connecting point where the two separate metal panels meet forms a vertically pointed rib or a seam that is one inch to inch and a half high.
Place the first panel with overlap leg along the alignment line.
Overlap the end a minimum of six inches when starting a new roll of underlayment.
This technique provides the cleanest look and shows no exposed fasteners.
Unlike steel and aluminum shingles standing seam panels should not be installed over the existing asphalt shingles.
In cold weather slide the panels tight against the eave flashing and in warm weather allow a gap for expansion.
