7 – Side Wall: This flashing is installed where the side of a roof slope meets a vertical wall, preventing water from seeping behind the wall panels.
16 – Monoslope Ridge: Used at the highest point of a single-slope (shed style) roof, this trim caps the transition from the roof to the back wall.
9 – Z Trim: Often used in horizontal siding transitions or window headers, its “Z” shape provides a ledge that directs water outward and away from the building.
8 – Fascia Cover: This trim protects the wood fascia boards from the harsh desert sun and moisture while providing a clean, finished look to the roofline.
15 – Hip: This trim covers the external angle formed by the junction of two sloping roof planes that do not form a ridge.
6 – End Wall: Used where the top edge of a roof slope meets a vertical wall, providing a water-tight seal against the siding.
11 – Rat Guard (Base Drip): Installed at the very bottom of wall panels, this trim prevents rodents and insects from entering the ribs of the metal while directing water away from the foundation.
13 – Inside Corner: Specifically designed for the interior 90-degree angle where two walls meet, ensuring a professional and weather-tight seal.
12 – Outside Corner: Used to join and finish two wall panels meeting at a 90-degree exterior angle, protecting the corner from wind and rain.
10 – J Channel: A versatile trim used to hide the ends of metal panels around doors and windows, creating a clean, recessed pocket.
14 – Base Drip: Similar to the rat guard, this is placed at the bottom of the siding to kick water out and away from the base of the structure.
