Standing-seam metal roof installation

Fasten the panel side with screws and the top of the panel with mill point screws. You are now ready for the second panel, which will be installed in the same way. Place sealant over the underlap rib before sliding the hem over the eave trim. Snap the first two to three inches of the panel together, and slide the panel tightly against the eave trim, or with the gap depending on the temperature. Snap the panels together and fasten along the opposite side and the top of the panel.

While installing standing seam metal panels, there are two basic ways to trim the gables of your roof: You can use a special gable trim or a regular drip edge. The special trim is often easier and safer to install. To finish off each end, cut along the bends and fold the top plane down 90 degrees toward the eave trim and cut other flaps flush.

Then install a bead of sealant tape along the rib of the panel, laying the gable trim in place. Fasten along the fascia board every 24 inches on center with a wood fastener or mill point screws. Next comes the installation of the ridge caps.

Place the ridge cap over the panel and fasten with stitch screws through each rib. Overlap the next ridge caps 6 inches with sealant between the laps. As an option, you can install solid or vented z-bar flashing between the ribs and fasten this down with roofing screws.

Use sealant between the z-bar flashing and the metal roofing panel. Also, seal the opening between the z-bar flashing and ribs on each end of the z-bar. Apply sealant to the back side of the closure near the ribs and over the flanges to seal gaps. You will first need to place an ice and water shield down the center of the valley. Cut the valley flashing to the angle and length needed to secure it over the ice and water shield.

Apply a bead of sealant tape to the bottom side of the valley cleat. Position the valley cleat 6 inches away from the center of the valley. Fasten with screws spaced 12 inches apart. Now you can start cutting and hemming panels for the valley.

Before installing the panels, place a bead of sealant tape along the eave flashing and on top of the valley cleat. Cut the climate guard panel at the appropriate angle and length to allow for a 1-inch hem at both the eave and valley cleat. This is done by cutting along the rib, so the bending tool can be used to complete the hem. To finish off the overlap rib, cut the metal to allow the inside flap to fold over the opening where it can be cut flush with the edges. Installing the panel can be done by placing sealant over the underlap rib and aligning the panel before snapping the panels together.

Once aligned, snap the panels together, working from the eave up the run of the panel. Secure the top of the panel with mill point screws. To finish off a panel at the gable end for side wall, first determine the width of the panel needed.

You must now close off the void created between the hip cap and flat portion of the panel. Save my name, email, and website in this browser for the next time I comment.

Lay down wood sheathing boards over the prepared surface — Sheathing boards help to create a smooth and even surface for the standing seam roofing to be installed on.

Install metal roofing clips — Metal roofing clips are what hold the standing seam roofing in place, so it is important to install them evenly and securely. Before cutting standing seams, it is important to mark each standing seam so that they can be lined up correctly Install standing seam roofing sheets — Once the metal roofing clips have been installed, the standing seam roofing sheets can be put in place.

Make sure to overlap the seams of each sheet by at least inches to ensure that water will not be able to leak through. Secure standing seams with cap screws — The final step in installing standing seam roofing is to secure the standing seams with cap screws.

Secure metal panel by using sealant or caulking along seams and edges — Once standing seams have been installed, you will need to seal the standing seams so that water cannot leak through the standing seams.

There are a variety of sealants and caulks available for sealing standing seams. Finally, install ridge caps, drip edges and gutters for better drainage — After standing seam roofing has been installed, it is important to install ridge caps, drip edges and gutters to help keep the standing seam roof in good condition. The following table highlights the main differences between exposed and concealed fasteners.

The main difference between these two types of roofing systems is the installation. Standing seam panels are joined together at the seams, while screw-down panels are fastened down on the roof using screws that go through the face of the metal. However, the two roofing systems differ in other aspects as well. Standing seam metal roofs have several advantages compared to other roofing styles. They include:. The most obvious advantage of a standing seam metal roof is the concealed fasteners.

Covering the screws protects them from the elements such as moisture, wind, and UV. It is through exposure to these and other elements that fasteners wear and fail over time.

Also, some people may feel that fasteners negatively impact the aesthetic appeal of the roof. Therefore, they would prefer a system that keeps them out of sight. The metal expands when hot and contracts when cold. As such, it should have enough room to move either way. The fasteners risk coming loose under pressure otherwise.

Furthermore, panels with no room for thermal movement are prone to increased noise and oil canning. Generally, standing seam metal roofs are not pinned. That means they can expand and contract with ease. When compared with other roofing systems, a standing seam metal roof is arguably one of the most durable options available. Since the fasteners don't go through the panels, there is no risk of them becoming loose or damaged. Therefore, maintenance need not be on a regular basis.

With that said, standing seam metal roofs still need maintenance. However, you would need to call a professional maintenance contractor owing to the high level of expertise required. But consumers also love its modern and chic look and the wide variety of color options. It is no wonder they are a popular choice in architectural applications. The fact that they are fit for use in buildings with complicated roof designs also helps.

Standing seam metal roofs often incorporate cool roofing technology. Some have highly reflective pigments on the surface that help in reflecting sunlight and highly emissive metals that dispel heat instead of absorbing it.

Cool roofing reduces the amount of energy and money that would have been spent on cooling. A standing seam metal roof enables you to mount items such as swamp coolers and solar panels onto the roof.

You don't even need to make holes on the surface of the panels. Installing a standing seam metal roof is not always the best option. The roofing system also has its disadvantages. The following are some of them:. Installing a standing seam metal roof is more expensive compared to other roofing styles with exposed fasteners. But it is not as expensive as other methods such as metal shingles.

Installing a standing seam metal roof requires specialized skills. Therefore, it is essential to find a skilled contractor with adequate experience. However, many contractors would consider the process too complicated and labor-intensive. As a result, you would be hard-pressed to find a contractor with the relevant experience.

Such a flat pitch would make it harder to drain water leading to premature degradation, color fading, and eventual failure. If damage occurs on one section of the roof, the repair process can be tedious. This is because you need to separate the damaged panels from the rest. In cases where the panels are mechanically seamed, separating the panels is even harder. A standing seam metal roof is one of the most durable roofing systems. As long as you follow the correct installation process and the ventilation in your attic is up to par, the roof should serve you for at least 30 years.

Of course, that will depend on the weather, paint finishes on the panels, and the level of maintenance. When the surface of the panel is scratched or damaged, it exposes the metal to the elements. That's why a painted finish is essential. It helps keep the elements at bay and retains the original color of your roof for longer. However, the type of weather can still have an impact on the longevity of your roof over time.

If you live in an area experiencing extreme weather conditions, your panels will wear and tear faster. For instance, the integrity and finish of your roof will weaken quicker if you live in an area that receives a lot of snow and hail.

Maintaining your roof is still important, no matter the type of roof you have. A standing seam metal roof may not need as much maintenance as other roofing options, but annual maintenance can help deal with problems at the penetrations.
