How Does A Standing Seam Metal Roof Work

The main idea to remember for standing seam systems is that the fastener is hidden whether the panel is attached to the roof deck using a clip or is directly fastened to the decking material under the vertical leg using a fastener flange.

How does a standing seam metal roof work. And if you put steel standing seam over asphalt shingles that are covered with stone granules the expansion and contraction of the metal will rub the underside of the panels against stones on the shingles. Contractors install traditional metal roofing by huge ridges. They lock the seams of each roofing panel ridge in place with nails. Houses in your neighborhood with metal roofs most likely are of the standing seam variety.

Standing seam metal roofing is a particular type of metal roofing that raises the seams above the level of the roofing itself. Continuous panels run from the ridge of the roof down to the eaves. This will sooner or later cause the protective coating to wear off thus inviting the rust spots to start popping up all over the roof. Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad flat area between the two legs.

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. Standing seam consists of sheet metal roofing panels joined side by side and attached to the roofing deck with concealed fasteners. The ribs standing seams are usually between 12 and 24 inches apart depending on the length of the panel and aesthetics of the structure. Standing seam systems can be used for either metal roofing which is the most common or metal walls.

To provide excellent insulation and prevent leaks contractors use caulk to seal the nailed seams. A standing seam metal roof takes a different installation approach than the traditional metal roofing method.
