Standing Seam Roofing

Standing seam roofing is a concealed fastener roofing system. It is one of the most durable and weather-tight roof systems available in the industry. Its concealed fastener design ensures that the fasteners aren't exposed to the elements which could cause them to fail over time. Since these panels are attached to the roof deck with clamps, they're free of any holes from nails or other fasteners which could allow moisture to seep through.

Standing seam metal roofing is one of the most durable and weather-resistant roofing systems available for residential and commercial properties. Known for its clean, modern appearance and superior performance, this system is especially well-suited for homes in the San Antonio area where intense heat, heavy rain, hail, and strong winds are common.

What Makes Standing Seam Different?

​​

Standing seam metal roofing system is a succession of vertical sheet metal panels connected side-by-side by a vertical locking mechanism called the seam. The seams can be seen from the ridge of a roof, all the way down to the eaves. The locked seam is raised by an inch or two above the panels in order to maintain water-tightness of the system. The raised seam also provides for a unique and distinctive appearance. As with most metal roofs featuring concealed fasteners, standing seam roofs are virtually maintenance-free, fire-retardant and resistant to strong winds, and are just as quiet as asphalt shingles, clay tiles, or wooden shingles/shakes when it rains provided you have solid sheathing underneath the panels and well insulated attic space. Standing seam metal roofs are available in a wide variety of Cool Roof rated colors giving you plenty of room to make that bold architectural statement, while also helping reduce your home's cooling costs.

 

Unlike traditional metal panels that use exposed screws, standing seam systems feature raised vertical seams that interlock above the surface of the roof. The fasteners are concealed beneath these seams, protecting them from moisture, UV exposure, and temperature fluctuations. This hidden fastener design significantly reduces the risk of leaks, corrosion, and long-term wear.

Panels typically run continuously from the ridge to the eave, eliminating horizontal seams where water could penetrate. The result is a sleek, streamlined look combined with exceptional watertight performance.

Superior Weather Resistance

​

Standing seam roofing is engineered to perform in extreme conditions:

• High Wind Performance: Properly installed systems can withstand wind speeds of 140 mph or more, providing reliable protection during Texas storms.

• Hail & Impact Resistance: Heavy-gauge steel or aluminum panels offer strong resistance to hail damage.

• Thermal Movement Accommodation: Metal naturally expands and contracts with temperature changes. Standing seam systems are designed with clip systems that allow controlled movement, preventing buckling or fastener failure.

• Water Shedding Design: The raised seams sit above the drainage plane of the roof, reducing the risk of water infiltration during heavy rainfall.

Energy Efficiency in Hot Climates

​

In South Texas, energy efficiency is a major benefit. Standing seam panels can be coated with reflective, ENERGY STAR®-rated finishes that reflect solar heat rather than absorbing it. This helps reduce attic temperatures and can lower cooling costs during long summer months. Many systems are also compatible with added insulation and ventilation upgrades for even greater efficiency.

​

Long Lifespan & Low Maintenance

​

One of the biggest advantages of standing seam roofing is longevity. With proper installation and minimal maintenance, these systems can last 40 to 70+ years. Because fasteners are concealed and protected, there are fewer points of failure compared to exposed-fastener metal roofs or traditional shingles. Maintenance typically involves periodic inspections and debris removal rather than frequent repairs or shingle replacements.
