What We Do

Warehouses and factories need roofing built for heat, wind, corrosion and long spans. We install and upgrade IBR and corrugated systems, flashings and drainage details that protect high-value operations.

Why Johannesburg Roofs Demand Experience
Johannesburg roofs take strain from heavy summer rainfall, hail events, strong UV exposure and rapid temperature changes. Many leaks start small at flashings, joints and gutters, then spread into insulation and steelwork.
Experienced roofing prevents repeat call-outs by fixing the weak points and restoring full waterproofing integrity across the entire system.

Common Questions
Roofing cost depends on roof size, access, system type and the amount of repair or replacement required. After an inspection, we provide a scope that separates urgent repairs from optional upgrades so you can plan budget correctly.
Most commercial roofs in Johannesburg should be inspected at least once every one to two years, and after major storms. Planned checks prevent small leaks from becoming insulation damage and steel corrosion.
Yes. When leaks or storm damage affect operations, we prioritise stabilising the problem, then follow with a permanent repair plan based on the roof system and failure points found on site.
We work on large-scale systems commonly found on commercial and industrial buildings. This includes metal sheeting such as IBR and corrugated, flat roof waterproofing systems, flashings and gutter systems.
Repairs fix specific failures like leaks, flashings or damaged sheets. Refurbishment is broader and can include surface prep, waterproofing upgrades and protective systems to extend roof life without full replacement.
Common causes include failed flashings, blocked gutters, deteriorated waterproofing, loose or missing fasteners, rust spread and poor detailing around penetrations. Our inspection identifies all failure points before quoting.
We cover Johannesburg and surrounding Gauteng regions including Sandton, Randburg, Fourways, Midrand, Roodepoort, Bedfordview, Bryanston, Rosebank, Alberton, Boksburg, Benoni, Kempton Park and Germiston. For multi-site clients, we support planned inspection and repair schedules across locations.
Yes. Maintenance contracts reduce emergency call-outs by catching issues early and keeping gutters, joints and waterproofing points in good condition throughout the year.
