Coping stones are more than just a decorative detail, they're an important and underrated construction essential that need to be considered before your next parapet upstand or boundary wall project.

From traditional copings to pier caps and even aluminium alternatives; there are many different types of coping stone to complete both new and existing projects. It doesn't matter if your latest job is smaller in scale or very large and elaborate in scope, coping is a smart, durable and incredibly valuable asset to your building's roof or wall structure.

In this blog, Roof Giant will give you the lowdown on the reasons why you should never overlook coping stones and how they can actually improve your project in terms of visual quality and structural reliability.

What Are Coping Stones?

Copings are flat, single weathered or twice weathered rectangular stones used to cap free-standing walls, parapet upstands, boundary or flat roof walls. Once installed they will provide you with a robust, visually appealing finishing touch that will give your project a completed look that is both decorative and practical.

The function of a coping stone is to protect the exposed upward wall face from rain and weather damage while preventing rainwater from seeping into the wall structure and compromising its strength over time. Roof Giant provide coping stones for any function-based or decorative project in building constructions and garden settings.

Why Should I Use Coping Stones In My Next Project?

Coping stones are imperative to wall projects, whether that be on a simple garden wall, roof parapet or similar application. Without coping stones in place, visual signs of weathering and actual weather damage can ruin your wall overtime, causing it to stain and even crumble.

The capping function of coping stones keeps water off your wall. The tough concrete or porcelain construction usually comes with a once weathered (single slope for water runoff) or twice weathered (caret '^' shaped ridge for runoff on both sides) design to allow water runoff without causing water ingress in the wall underneath.

Coping stones are hugely important when it comes to your wall project. They protect walls from weather damage and come complete with drip checks - which help to keep water away from the wall. Coping stones are manufactured from high-strength concrete and provide an aesthetically-pleasing finish.
