Zincalume 170mm Flat Ridge Roof Flashing

The 170mm Zincalume flat ridge roof flashing finishes the ridge line of a Trimdek or similar ribbed roof, sealing the apex where the two sheet slopes meet. It is shaped to sit over the Trimdek profile and carry water down each slope, keeping the ridge watertight in an unpainted aluminium-zinc finish. It is made from 0.55mm BMT Zincalume steel, cut to length with a +200mm / -0mm tolerance, and sold per lineal metre.

Frequently Asked Questions

Which roof profile does this ridge suit?

It suits Trimdek or similar ribbed roofing sheets, sitting over the ridge apex and shedding water down both slopes.

Why use the Zincalume finish?

Zincalume is an unpainted aluminium-zinc coating that resists corrosion without painting, so it suits commercial roofs and coastal areas where a colour match is not needed.

How is it priced?

It is priced per lineal metre including GST and cut to your required length with a tolerance of +200mm / -0mm.

Can I get it in Colorbond?

Yes. The same 170mm flat ridge is available in Colorbond for a colour-matched finish.
