Options for Industrial Roof Insulation

An example of a roof that needs industrial roof insulation

If your building is loud, hot in summer, cold in winter, and dripping with condensation after a Highveld storm, the culprit is usually the roof build-up. Industrial roof insulation is the layer (or layers) that controls heat flow, moisture, and noise in large-span buildings like warehouses, factories, cold stores, and logistics hubs. Get it right … Read more

Common issues with industrial roof gutters

Industrial roof gutters protect structures from water damage by channeling the water away

When we talk about industrial roofing, we’re talking about big, hard-working envelopes—distribution centres, factories, processing plants, cold stores, and logistics hubs. These roofs cover a lot of area, host heavy services, and face intense wind uplift and torrential summer storms. The quiet workhorse on their perimeter is the guttering system. Industrial roof gutters are not … Read more

Engineering considerations for commercial roofing

an example of commercial roofing

When people hear “Commercial roofing,” they often think of a vast flat slab covered with waterproofing. Engineers see something else: a coordinated system of structure, waterproofing, drainage, insulation, vapour control, fixings, edge restraint and safe-access hardware—all tailored to a building’s climate, loads and use. Get those pieces working together and you gain a roof that … Read more

Roofing certifications required in South Africa

Roofing certification ensures that roof structures are sound

If you’re planning a new roof or a major roof replacement, roofing certification isn’t a nice-to-have—it’s part of getting your building legally signed off. In South Africa, municipalities rely on a specific paper trail to confirm that the roof was designed, built and inspected by competent people in line with national standards. This guide explains … Read more

The purpose of the roof frame truss

A Truss hanger is a pre-formed metal connector that supports and fixes a roof frame truss like this

When you look up at a finished roof you see tiles, sheets, ridges and gutters. Hidden beneath that outer skin is the real workhorse: the roof frame truss. In modern construction, the roof frame truss is the pre-engineered, prefabricated skeleton that defines the roof’s shape, carries the covering, and safely channels wind, rain and maintenance … Read more

Considerations for Commercial Roofing

An example of commercial roofing

Commercial buildings ask far more of their roofs than houses do. Larger spans, heavier services, busier foot traffic, and relentless exposure all raise the stakes. In this guide, we unpack what commercial roofing is, the key decisions that shape performance and cost, common pitfalls to avoid, and how Dezzo Roofing engineers systems that last in … Read more

The benefits of steel roof trusses

An example of steel roof trusses

If you’re planning a new build or a re-roof, you’ll quickly hear the term steel roof trusses. In simple terms, these are triangulated structural frames manufactured from cold-formed (light-gauge) or hot-rolled steel members, engineered to carry the weight of your roof covering plus wind, maintenance and other loads—then transfer those forces safely into your walls … Read more

What is a truss hanger?

A Truss hanger is a pre-formed metal connector that supports and fixes a roof frame truss like this

A Truss hanger is a pre-formed metal connector that supports and fixes a roof truss (or joist/beam) to another structural element—typically a wall plate, steel/timber beam, or a girder truss. Think of it as a small, engineered cradle that provides bearing and secure load transfer without bulky cleats or time-consuming carpentry. In modern roof construction—especially … Read more

Everything you need to know about battens

There are various components to consider in roof engineering, including battens

If trusses are the skeleton of a roof, battens are the muscle fibres that tie the covering to that skeleton. They look simple—just long, narrow members fixed across rafters or truss top chords—but the performance of your tiles, slates or sheets depends on getting battens specified and installed correctly. This guide explains what battens are, … Read more

The purpose of rafters

An example of timber rafters

When you strip a roof down to its structure, the element most people picture first is the rafters—the sloping members that climb from the wall plate or beam up to the ridge. They form the primary framework that defines your roof’s pitch and shape, carry the covering and transmit loads safely to the walls and … Read more
