Standing Seam Roofing

We manufacture Standing Seam Sheeting to length made from SSAB pre-coated galvanised Swedish steel. Innovatively designed to conceal fixings, Standing Seam creates a sleek, modern architectural look. Standing Seam Sheeting is a popular Roofing and Wall Cladding material in domestic and commercial settings.

The GreenCoat® Pural BT coating is sustainably produced using Swedish rapeseed oil which allows for a corrosion, weather, scratch and UV-resistant surface offering a life of up to 40 years depending on the environment. Cladco Standing Seam Roof Sheets are made from steel that is A1 fire-rated to BS EN 13501.

Made to length in our factory, Cladco Standing Seam Roofing Sheets can be produced in lengths of up to 8 metres and provide coverage of 500mm in width when lapped. We make our Standing Seam Sheeting with two options:

With or without ribs in the pan of the Sheet: Ribs help prevent drumming in high winds and oil canning, where the Sheeting may bow or wave in the flat part of the panel due to inconsistencies in the roof sub-structure, whereas the design without ribs is often chosen for its aesthetic appeal.

With or without an eaves fold: When used for Roofing, this is a fold at the bottom of the Sheet that can be further folded onto an Eaves Flashing to make for a more secure bottom edge. When using Standing Seam Sheeting for Side Cladding, an eaves fold would not usually be required.

An extensive range of Flashings are available to install with our Standing Seam Sheets to complete your roofing or cladding project.

Installing Cladco Standing Seam Sheets

Before installing Standing Seam Sheets, 18mm OSB board, or plywood board, needs to be installed over the roof’s frame, then covered with breathable membrane stapled into place. When installing Cladding and Roofing, undergo the Cladding installation first.

Roofing

Install Backer Plate Flashings to the ridge (for mono-pitched roofs) and verge, as well as Eaves Flashings where required, using Annular Ring Nails to secure through the Flashings to OSB or plywood.
Working from right to left, cut off the right-hand seam of the first Standing Seam Sheet and create a 25mm upstand. The upstand will be used to indicate the edge/start of the Cladding and will be later covered by a Flashing.
To fix Sheeting, drive Ring Nails through the perforated fixing holes at the edge on the left-hand side of the Sheet either with a hammer or a nail gun. Hammer Ring Nails in the middle of the fixing hole slot to allow for any expansion or contraction in both directions. As a rule, nail through every third hole down the perforations or every second hole for particularly exposed areas.
Line up the next Sheet and install by tapping seams together starting at one end and working your way along the Sheet using a rubber mallet. Sheets will snap together along the seam and can be separated again, if required, by lifting the left edge of the sheet before it has been nailed into place.
Cut the last Sheet to width and fold a 25mm upstand to be covered by a Verge Flashing and to help prevent water ingress.
Secure Z Bars (Notched) along the top of your roof just under the ridge line. Position the Z Bar using a temporary Ridge Flashing piece along a straight line.
Measure and cut Ridge Flashings or Mono Ridge Flashings to fit along the apex of your roof to complete your installation.

Cladding

Install J-Rail Flashings along the eaves and Drip Tray Flashings to the base of the Wall Cladding area.
Fix Sheets to boards using the same technique as Roof Sheeting.
Fix Z Bars to both sides of a corner using Ring Nails and clamp onto the Corner Barge Flashings to finish.
