Our metal roofing installation expert walks you through the installation of a ridge cap on a metal roof. Watch the instructional video above or read through the steps below to help educate your customers on how they can effortlessly install a ridge cap on their metal roof. Before you get started on the installation process, be sure you have all the tools necessary:
Once you’ve installed your metal roofing panels on both sides of the roof, you will need to close off the ridgelines. We will walk you through the steps for installing both ventilated ridge caps and closed ridge caps using our SL-16 concealed fastener metal roofing system.
Installation of a closed ridge cap is fairly straightforward. You will need to make sure you prep the Z-trim underneath before you install the ridge cap. Follow the instructions below:
Next, we're going to start working on the vented ridge in this application for SL-16. There are a few things to consider before you’re able to install your ventilated ridge cap.
Since every building and house is different, it's important to evaluate a building based on the construction, what's taking place inside the roof cavity and what kind of insulation is used. Generally, there's a lot of confusion about venting soffit and ridge versus gable venting. So one important note is to make sure that you're using either a ridge vent in combination with open soffits or you're using gable venting, but that you're not combining the two. If you combine the two, cross airflow cancels each other out and you end up with a much less effective venting of your roof cavity.
In this particular installation, we have open soffits, so we're going to open the ridgeline so that we can install our panel and the profile vent material.
You are ready to install the vented ridge cap. Since you’ve made a cut 2” on either side of the centerline of the ridge, you now have to install a ridge cap with the vented ridge material. In our example, we used ABC vented ridge material that’s been die-cut to fit the SL-16 panel. To install it, use an anchor clip system and tape seal on the underside. The first thing that you want to do is make a mark so that you know where to position the profile vent. Then, put the ridge cap in place, mark the tops of the ribs and line it up with the ridgeline. Using a pencil, make a mark on top of the panel ribs. When you remove the caps, the marks let you know where you need to like up the profile vent. Installing the Clips & Profile Vent The profile vent system consists of the vented material and the clips. The first thing that we must do is install two clips per SL-16 panel and then thread the profile vent through the clips. Each roofing panel will have two anchor clips fastened to it.
Once that’s done, we have the installation of two clips with a profile vent held securely in place. Fastening The Ridge Cap To The Clips Now that you’ve installed the profile vent, the next thing to do is put the ridge cap in place and fasten it to each of these clips.
Once you’ve fastened the ridge cap to all the clips, you will have completed your metal roof ridge cap installation.
