Metal Standing Seam

Roofing Systems

  • Metal System Components

    • The hill country is crazy about metal. Metal roofs come in two different categories, exposed fastener and concealed fasteners. Standing seam below will clarify the concealed systems. Exposed fastener panels come in dozens of styles. Common styles include R- Panel, V-Crimp, Corrugated, U-Panel and other variations but they all need a neoprene screw through the top of the panel to secure to the wood deck or frame of the building. See below for a short summary of variations of metal screw down panels.

  • Standing Seam Systems

    • Metal Roofing been used throughout history to stand the test of time. From the Romans who used copper as a roof covering for the Pantheon to alloyed metal roofs in European medieval architecture, these metallic structures are characterized by high resistance, impermeability and longevity. Modern standing seam roofs as we know them were developed in the 1960s and use metal as the roofing material instead of asphalt, tile or slate. Many options are available today, including aluminum, copper or aluminum-zinc alloy coated steel.

    • The term standing seam comes from the connections between the metal panels that are raised. The seams run vertically and are created by folding and crimping the edges between the panels. These roofs require minimal maintenance and provide both extreme resistance to high winds and a high fire rating. As a durable choice for roofing, we’re exploring the systems, materials and performance of standing seam roofs.

  • Underlayment - Synthetic vs PSU

    • Synthetics are woven or spun from either polyethylene or polypropylene. While the ingredients are similar, the manufacturing process and thickness of each type of underlayment can be fine-tuned to produce different properties, such as exposure time and walkability. Often secured with plastic caps, synthetics are more durable, more resistant to keep water out of the roof and are now considered to be a step above a regular felt based products. Synthetics are approved under all residential roofing systems.

    • PSU (Peel n Stick Underlayment) is a true membrane system composed of two waterproofing materials—an aggressive rubberized asphalt adhesive backed by a layer of high density cross laminated polyethylene. The rubberized asphalt surface is backed with a fold-less release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. This is the premium roofing underlayment given that its a self sealing membrane system on its own, basically giving you a first layer of roofing before you ever install your shingles, metal or tile roof systems.
