Low Pitch Solutions
When considering low pitch roofs, there are a number of factors that must be considered to ensure a successful installation ,the pitch of the roof, the type of slate being used, the size of the lap, the size of the slate as well as the site’s exposure rating. You can be assured that at SIG Roofing we have the perfect solution and a range of options to achieve a durable, reliable and stylish finish.
Relating to the pitch, the building standard code BS 5534 recommends a minimum pitch of 20 deg for slate roofs (which can be achieved through specific design although most manufacturers recommend a 25° degree minimum pitch). But since there is still a wide variety of slate roofing systems, there are occasions when the minimum pitch can go down to as low as 15° / 12.5° depending on the design of the roof.
SIG Roofing can supply a number of solutions to cope with these lower pitches such as Cambrian roof Slate or Regent Tiles which can be used on pitches as low as 12.5 degrees.
Cambrian Slates embody the beauty and character of natural slate. Made in Wales from over 60% recycled Welsh slate, Cambrian tops the range in both looks and performance and has a proven track record even on pitches as low as 15°. Whilst light in weight, Cambrian’s unique three point fixing makes it suitable for even the most exposed sites.
Regent tiles are characterised by their high, bold roll profile, creating a striking and unique effect on the roof. They are available in a wide range of colours and three surface treatments; smooth, granular, and clear acrylic coated to suit all roof types.
In addition, Regent can be laid at pitches as low as 12.5°, making them ideal for extensions and lean-to-roofs where the rafters have to fit below existing window cills, Imerys Clay Panne H2 Tile can be used down to 17.5 deg.
Alternatively, SIG Roofing have a comprehensive offering of flat roof products which can be used if the pitch is lower than those mentioned above. These options are available to view here in our Flat Roof Section.
