Rubber Roof Trims Guide – What they are, why they matter, and why QuickTrim outperforms the rest

What are rubber roof trims – and why are they important?

When it comes to flat roofing, the small details often make the biggest difference. Rubber roof trims might seem minor, but they play a major role in protecting your install. These trims secure the edge of your EPDM membrane, direct water flow, prevent wind uplift, and create a clean, professional finish.

Without proper edging, water can creep underneath the membrane, fixings are left exposed, and UV degradation can start to set in. Trims are not just aesthetic – they’re a vital part of the waterproofing system

Types of QuickTrim rubber roofing trim and their applications

There are two key trim profiles used for most flat roofs:

Drip Edge Trim – Installed on the gutter-facing edge. Guides water neatly off the roof and into the gutter.
Check Kerb Trim – Used on the remaining edges. Prevents water run-off and pushes it back toward the drip edge.

These are supported by matching accessories like corners, joiners, and end caps. The right combination ensures a secure, neat and watertight perimeter – without any guesswork or on-site mitring.

Inferior roof trims vs QuickTrim – the difference is clear

There’s no shortage of low-cost options on the market. But cheaper trims often mean hollow, brittle plastic, awkward clips, and poor weather resistance. That’s where the headaches start: call-backs, cracked edges, lifting trim caps, and unhappy clients.

QuickTrim, Plytech’s original flat roof trim system, was designed to eliminate these issues. First introduced in 1999 and still trusted by roofing professionals today, it’s made from high-strength recycled polystyrene, with:

Solid corners (no flimsy joins)
Hidden fixings for a clean finish
UV stability for long-lasting colour
Factory-fitted gaskets for watertight joints

It’s the original for a reason – and it’s still the best.
