Instructions for installing a steel sheet / panel on the roof using the seam-joint method.

A standing-seam panel is a perfect way to create an interesting arrangement for the roof or walls of a building. The biggest advantage of such a solution is its universally aesthetic aspect. Standing-seam panels can be found on the roofs of historical buildings, as well as on the roofs of modern housing estates of single-family units or multi-family dwellings.

How do you choose the best seam sheet? A good roofing material should, above all:

  • be made of high-quality steel,
  • have high resistance to corrosion and mechanical damage,
  • and be available with a ready-to-use system of flashings and accessories.

Before buying and installing a steel sheet, a suitable coating must be selected.

  • Cesar PUR 55 coating – highest-strength polyurethane coating with polyamide, with a thickness of 55 μm.

  • SP Polyester Matt Pearl 35 coating – aesthetic appearance and high strength, and a matt polyurethane coating with a thickness of 35 μm.

  • SP Polyester 25 coating – economical solution, polyurethane coating with a thickness of 25 μm.

How much does it cost to lay a steel sheet using the seam-joint method? What is the price of the roof?

The cost of installing the panels depends on many factors, such as the selected coating, the roof shape, the experience of the professionals from the roofing company, and the region where the investment is being made.

Instructions for installing the Elegant seam-joint panel.

1. To install an upright seam panel, you will need:

  • upright seam panel sheets,
  • cordless drill,
  • metal sheet shears or nibbler,
  • set of flashing screws,
  • set of panel installation screws.

2. Start the installation by laying a vapour breathing membrane. In the example project, the membrane is laid on full roof boarding.

3. Next fit the counter battens and battens to the rafters. Batten spacing should be 25 cm.

4. Remember to install the under-gutter and over-gutter flashing while installing the counter battens and battens.
In this example this was not necessary due to the building design.

5. The next step is to lay the panels. Start the installation from the roof edge, ideally from the side from which the wind blows most often.

Pay particular attention that the panels are laid perpendicular to the eaves. This will facilitate installing the other panels.

The lower edge of the first panel should face the eave flashing bend.

6. After determining the right angle, the internal part of the panel is fitted to each batten with screws, at the prepared openings. The sheet is fitted by fitting the screw in the centre of the opening. Fit the screws tightly enough to enable the sheet to expand and contract as the temperature changes.

The entire roof slope is laid according to the following procedure:

- fit the final uncut sheet on either side of the roof to all the battens, and repeat for each previously laid sheet. Fit the centre sheets to the upper batten, the three lower battens and every second batten.

7. Fit the lower sheets by pressing the panel into the lock, starting from the eaves to the roof ridge.

To press the sheet, you can use a rubber mallet. Remember to align the lower edges of the sheets.

8. Pay particular attention to the last sheet, which usually requires cutting. For this purpose, draw a line at the roof slope end and then cut the panel to extend 30 mm outside the roof slope edge. For cutting, you can use hand or electric shears.

Bend the excess metal sheet upright.

Next, fit the panel to the end wall using screws, at the pre-drilled openings, with a diameter of not more than 3 mm.

9. The next step is to install the roof ridge finishing. This consists of two components: the ridge tile and the ridge tile flashing.

First fit the ridge tile flashing, using Farmer-type screws. To determine the installation point, place the ridge tile at the top of the roof and mark the locations of the ridge tile edges. Install the ridge tile flashing 20 mm above the drawn line, so that they are covered by the ridge tile. This will ensure the free flow of air under the ridge tile. Remember not to fit the flashing to the battens, but to the roof slope, ideally with two sheet metal screws.

Next, install the ridge tile by fitting it to the ridge tile flashing with self-drilling screws, at a spacing of not more than 50 cm. Flashing overlap should be at least 10 cm.

A wind brace should be installed as well, which is fitted to the end wall using 4.8/20 self-drilling screws. Install the wind brace on the other roof slope end in the same way.
