Step #1: Getting Started

To begin this Ondura roofing panels installation guide, we will first talk a little about the roofing surface you plan to mount the panels on. For example, you have two different ways to install them. First, you have the horizontally spaced installation method.

For this method, you need one-inch thick boards, and you will have to space the panels based on the slope of the roof. Understandably, as the paneling sits on a slope, this makes it easy for it to slide off the roof. To combat this problem, you can install brackets on the roof to hold them in place.

With the other method, you will use a solid decking surface with 1.5-inch thick plywood. After the plywood, you will lay down appropriate weather under laymen. As you lay the panels, you should measure an overhang of 1.75 inches.

Step #2: Installing Foam Enclosure Strips

Underneath the roofing, you will install foam enclosure strips. This weatherproofs your roofing system so that water can’t seep into your home. As any good Ondura roofing panels installation guide will explain, you need the paneling because it stops leaks from happening and extends the lifetime of your investment on your roofing system. After you have installed the weather enclosure strips, you will need to install fasteners at every corrugation.

Expert’s Note: You don’t necessarily need to install fasteners at every corrugation. Also, you can install them at every other corrugation in sections where the paneling will not be vulnerable to the wind. However, in parts open to the wind, you will want to place fasteners at every corrugation to hold it down.

Step #3: Overlaps and Seams

As you lay down the paneling, you will create overlaps and seams. It’s important to do this correctly. You don’t want the seams to align, or it can cause leaks in your roof. When you do an overlap, it should center over pilings. You should measure at least a 7-inch overlap.

Expert’s Note: Overlaps will have increased vulnerability to the wind. You want to protect your paneling from predominant winds. To do this, you will place a row of fasteners at each corrugation of the overlap.

Step #4: Installment of Ridge Caps

This Ondura roofing panels installation guide hopefully makes installation a little easier. Before you lay down the ridge caps, you will first want to weather proof your roof. You will do this through a foam enclosure strip that seals your roof from rain and other dangers. Once the foam enclosure strips have been installed, you must lay down your ridge caps. You should install them on one end and work to the other end as you go along.

Step #5: Folding the Ridge Caps

As you come closer to the end of your ridge caps, you will have to fold it. To do this, you first need to cut a slit in the ridge cap. After you have done that, you must close up the ridge cap and cut a slit down the center and fold the ridge caps over each other for an airtight weather proofing. Once you have folded the ridge caps, you will place one fastener on each side to hold it in place.

Step #6: The Final Step in Weatherproofing Your Paneling

The final weatherproofing of your Ondura roof will have almost the same process as in the other steps, except you don’t need the awnings to line up with the pilings. The awning will attach to your vertical wall, and you need flashing to achieve a true weatherproof transition. Before you start, check to know the specific requirements.

The metal flashing gives a clean finish, but you will have to cut a single corrugation to use it as the flashing. Next, you must place it on the side of the roofing. Keep in mind, your paneling must be divisible by four inches, or it will not look right. However, you can compress the panel if you need a more custom fit.

Expert Tip: In this Ondura roofing panels installation guide, we want to boil things down to as simple as possible. Instead of installing the paneling on the roof as you go, you can make it easier if you preinstall the fasteners as well as the strip foam in advance.

How much Ondura roofing panels cost depends on the product chosen, but in general, you can expect to pay between $23 to $269 to install paneling on your roof. Check the coverage, but most paneling will cover 26 square feet before you have to buy more paneling.
