AGI offers you a range of roof systems to match your commercial installation requirements and your budget.

Every roof design has been tested for fit at the factory. All roof designs were initially assembled by our engineers before the first one shipped. This extra quality step means you don’t have to worry about dealing with a “prototype” during installation. Every bolt hole lines up. Every sheet matches. Rafters and purlins are precisely manufactured.

We know. Because we already built each size in-house before they were released to manufacturing and shipped to customers.

Engineered for long life and trouble-free construction.

"C" Design Rafters & Purlins - Extra-large manway is sized for plenty of shoulder-room and easy maneuverability, even for large-framed farmers wearing cold-weather gear!

XL Stair-Stepped Ribs - Extra-tall 3-3/4″ (9.5 cm) stair-stepped ribs are staggered to provide even greater strength. Hemmed drip edge deflects moisture, eliminates sharp edges to reduce injury and strengthens the cross-section of the roof sheet.

Roof Vents - Well-designed 2.25 sq. ft. (0.686 m2) roof vents for maximum airflow. Vent openings are pre-punched for easy construction and tight fit and seals. Vents feature seamless raised lip (inset) for improved integrity and moisture resistance.

Roll Former - Proprietary state-of-the-art roll former controls the distance between holes from rib-to-rib, not from the edge of the coil-like competitive products. The result: Higher quality roof sheets that fit better—with bolt holes that line up every time. Bolts drop right in place. That means trouble-free, labor-saving, frustration-free installation on site.

XL Manway - Extra-large manway is sized for plenty of shoulder-room and easy maneuverability, even for large-framed farmers wearing cold-weather gear!
