How Does A Standing Seam Metal Roof Work

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.

How does a standing seam metal roof work.

It s also described as having raised seams or vertical legs that rise above the level of the panel s flat area. A standing seam metal roof system is a series of panels that are locked together at the seams or seamed mechanically. The ribs standing seams are usually between 12 and 24 inches apart depending on the length of the panel and aesthetics of the structure. Houses in your neighborhood with metal roofs most likely are of the standing seam variety.

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. To provide excellent insulation and prevent leaks contractors use caulk to seal the nailed seams. Contractors install traditional metal roofing by huge ridges. Continuous panels run from the ridge of the roof down to the eaves.

Standing seam consists of sheet metal roofing panels joined side by side and attached to the roofing deck with concealed fasteners. Standing seam metal roofing is a particular type of metal roofing that raises the seams above the level of the roofing itself. When installing a standing seam it is strongly recommended that all asphalt shingles are removed before the installation in order to prevent avoid the telegraphing effect where horizontally installed shingles punch through the vertical sheet metal roofing panels causing unsightly dents that cannot be fixed removed. 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.

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. 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.
