How to Install Barrel Cap Trim

"I'm Tom Shean and today on behalf of Expert Village I'm going to show you how to install a metal roof. Barrel cap trim is installed from the bottom up course to course with the panels. Install the end disc, position the first cap on the rig with the rear portion against the panel flange. Noting the open distance between the tile disc and fascia, notch the first cap only so the first barrel trim fits the fascia. Install the balance of the caps without notching. Position caps by rolling so that the exposed edge along the fascia forms a straight line while remaining tight to the panel. Fastening is by a single fastener down through the front flange into the wood blocking, scribed, cut and install the adjoining peak caps so one overlaps the other exposed right side. As a caution please ensure the caps are installed with correct slap. The small flange overlaps the large flange and faces down the roof. An end disc is installed in the first cap at the fascia. The barrel trim is then positioned and the disc scribed and notched to ensure a tight fit of the panel and fascia. The balance of the barrel trims are then laid from the bottom up fastening again as down through the front flange and into the hip board. The junction of the hip caps at the peak is similar to the rig installation where they are coat and lapped over. At a valley termination cut and fold the cap closed. If ventilation is required, metal hip backer can be special ordered as vented. Please note, the fitment and design of the barrel ends particularly at the hips are varied and considered to be an installer signature. Please ensure that all voids are all sealed to stop vermin and bird entrance."
