Different design options:
- Natural zinc; shiny, metallic surface which develops a patina over time.
- VMZinc Azengar; a pre-paginated product which provides smooth, matt surfaces.
- Textures; roller-applied textures can also be incorporated, which can create unique textured finishes such as grooves, ripples and even fish scales.
- Pre-pigmented varieties; specific your own zinc roof colour from warm red to purple.
- Fixing methods; standing seam roofs or shingle systems (small individual metal sheets).
Various installation methods:
Eaves installation: Using the swept end method (this type of detail is elegant but requires more time and skill).
Hip installation: Traditional hip installation and the G3 hip method. G3 method can only be used when the distance between clips is less than 940mm. The traditional hip method cannot be vented – it is also the only design where flattened seams are acceptable.
Ridge installation: Can be used on warm (non-vented) and cold vented roofs.
Verge installation: Created either by using a G3 or a standing seam verge. Here, the downstand needs to be at least 60mm. The G3 verge can also be used on curved roofs with a radius of 3m.
Transverse junction installation: Using standing seam zinc roofing panels together using steps or welted joints.
Valley installation: This can only be used on roofs where the slope is at least 14 degrees.
Your new zinc roofing project can also include rooflight installations, windows as well as fascias.
