Metal roof waterproofing done by roofers first.
A coating is only as good as the roof beneath it. Sicon Group has worked Gauteng roofs for over 26 years, so every metal roof waterproofing job starts with a proper inspection: rust treatment, sheet and fastener repairs and clean preparation before any membrane is laid.
Only then do we apply a seamless, fully bonded liquid membrane system and back it with a written guarantee. See the wider portfolio at sicongroup.co.za.
Metal roof waterproofing done properly.
Complete waterproofing systems for industrial and commercial metal roofs across Gauteng.
Liquid Membrane Systems
Seamless, fully bonded liquid membranes that move with the roof and leave no joints for water to find.
Torch-On Membrane
Heavy-duty torch-on waterproofing for flat and low-pitch metal roof sections that take real water load.
IBR & Corrugated Sealing
Lap, ridge and fastener sealing on IBR and corrugated sheeting, stopping leaks at every overlap.
Rust Treatment & Priming
Corrosion is cut back, treated and primed so the new system bonds to sound steel, not flaking rust.
Gutter, Flashing & Parapet
Box gutters, flashings and parapet walls sealed and reinforced where most roof leaks actually begin.
Leak Detection & Repair
We trace leaks to the true source, repair the cause and reseal, instead of patching the symptom.

Metal roof waterproofing questions answered.
How much does metal roof waterproofing cost in Gauteng?
Cost depends on the roof size, type, condition and access. Every metal roof is different, so Sicon provides a clear, itemised quote within 24 hours of a free on-site assessment, with no obligation to proceed.
How long does metal roof waterproofing take?
Most commercial metal roofs are completed within a few working days, depending on size and the amount of repair work needed. We agree a clear timeline before starting and stick to it, weather allowing.
Do you repair rust and leaks before waterproofing?
Always. Sicon is a roofing company first. Rust is treated, loose sheets and failed fasteners are repaired and the surface is primed before any membrane is applied. We never seal over a problem.
What waterproofing system do you use on metal roofs?
We specify the system to the roof: seamless liquid membranes for most metal roofs, and torch-on membrane for flat and low-pitch sections. The choice depends on the roof's pitch, age and exposure.
Do you offer a guarantee on metal roof waterproofing?
Yes. Every full waterproofing system carries a ten-year written workmanship guarantee against leaks, lifting and blistering on a properly prepared roof.
