How Does A Standing Seam Metal Roof Work

Houses in your neighborhood with metal roofs most likely are of the standing seam variety.

How does a standing seam metal roof work.

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. They lock the seams of each roofing panel ridge in place with nails. It s also described as having raised seams or vertical legs that rise above the level of the panel s flat area. 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. A standing seam metal roof takes a different installation approach than the traditional metal roofing method. 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 metal roofing is a particular type of metal roofing that raises the seams above the level of the roofing itself.

A standing seam metal roof system is a series of panels that are locked together at the seams or seamed mechanically. 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. 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 systems can be used for either metal roofing which is the most common or metal walls. Contractors install traditional metal roofing by huge ridges.
