Can You Overlap Metal Roofing Lengthwise

To overlap metal roofing lengthwise, you will need to use metal roofing screws.

Metal roofing is one of the most durable and long lasting roofing materials available, but it can be tricky to install properly. One of the most important installation techniques is properly overlapping the metal panels.

Most metal roofing panels come in lengths of 3′ or 6′. When installing the panels, it is important to make sure that each successive panel overlaps the previous one by at least 6″. This will ensure that the roof is watertight and will prevent wind damage.

It is also important to properly seal the seams where the panels overlap. Use a high quality roofing sealant to ensure a long lasting seal.
