Standing Seam

Pro-Seam is available in a range of panel types, depths and widths to suit design requirements.


For design purposes, it is assumed that Pro-Seam panels are fully supported – whether by timber board or rigid insulation. Modern style SIPS panels with plywood facing provide a perfect sub-structure, with a breathable membrane included to control condensation.


The Pro-Seam concept is based on the tried and tested principle of longstrip roofing – thin metal panels laid onto a suitable deck, usually of timber, with panels seamed by hand over a separate clip system, which would be ‘rolled’ into the seam. The roof material might be lead, copper or zinc.


The use of modern high tensile materials such as steel and aluminium has allowed the development of stronger, more functional roof panels, increasing speed of installation on site, lowering costs but maintaining the appearance of  more traditional standing seam roofs.  


Pro-Seam Snaplock


ProSeam - Snaplock panels are roll-formed from continuous strip coil to the required length. The system incorporates a separate clip which secures the leading edge of each panel during construction. This clip is nailed or screwed to the timber substrate. The overlap edge of the next panel simply snaps over the upstand so the clip is incorporated into the panel seam. The clip design permits thermal movement on longer roof slopes where expansion of the metal may be a design consideration. No additional mechanical seaming is required.

Pro-Seam Nail-strip


The Nailstrip panel is perhaps the simplest and most practical of the ProSeam range.


With no separate clip within the panel arrangement, individual panels are secured by means of nails or pan head screws. The leading edge of each panel is perforated to facilitate site fixing. The overlap or ‘female’ edge is then snapped over the male counterpart to secure each panel to its neighbour. No additional seaming or zipping of seams is necessary.


Pro-seam Traditional


Manufactured in a very traditional way, albeit on state-of-the-art machinery, traditional panels are laid, fixed and seamed to form a double lock seam. This neat arrangement ensures a tight, secure seam detail and does permit the incorporation of more traditional ridge and verge details. The finished seam can either be angled or double lock-formed.  An electric seaming tool is used to secure the main panel seams, while hand tools can still be used for more awkward or complex details.
