IBR Roof Sheeting Waterproofing & Leak Repair in New Muckleneuk, Pretoria

Location: New Muckleneuk, Pretoria
Service: IBR metal roof sheeting maintenance, waterproofing and leak repair

A busy retail and restaurant building in New Muckleneuk had been living with the frustrating kind of roof problem — no single dramatic leak, just damp patches that seemed to move around every time it rained. The building’s IBR (corrugated metal) roof sheeting had done years of service, but age and old, failed sealant at the joints had turned the screw lines and box gutters into a network of small entry points for water. Eco Seal was called in for professional commercial roof waterproofing.

The problem on site

Up close, the roof told the real story. Along the ridge flashings and box gutter joints, old sealant had cracked, shrunk and lifted away from the metal, leaving open gaps for water to track underneath the sheeting. Several fastener lines had lost their seal entirely, and corrosion had taken hold around one rusted box gutter section where water was pooling instead of draining away. The existing box gutters were also undersized flashings rather than proper gutters, so heavy rain simply overwhelmed them. None of this was visible from ground level, which is exactly why problems like this get missed until they show up as ceiling stains inside the building.

The Eco Seal solution

Eco Seal Group, an approved SealPro applicator, carried out a full remedial waterproofing and repair programme rather than a quick patch job:

1. Assess and strip back — every ridge cap, box gutter joint and flashing was inspected, with old, failed sealant and loose or corroded material removed back to a sound substrate.
2. Replace undersized flashings with proper box guttering — the old flashing-as-gutter arrangement was removed and replaced with correctly sized box gutters.
3. Rebuild the joints — rusted, open sections at gutter corners and ridge junctions were rebuilt using reinforcing fabric bedded into fresh sealant.
4. Waterproof every screw line — a SealPro fastener and screw treatment was applied to each of the roof’s exposed screw fixings.
5. Seal the ridge and valley joints — SealPro’s flexible ridge and joint waterproofing system was applied along the ridges and valleys using a fibre-reinforced membrane.
6. Final inspection — once cured, every treated line and joint was checked for full coverage and adhesion.

The result

The roof went from a patchwork of open joints, cracked sealant and an undersized gutter system to a fully re-sealed, properly draining IBR roof. Every screw line is now individually waterproofed, the failed ridge and gutter joints have been rebuilt with flexible, reinforced sealant, and the new box guttering gives the roof the stormwater capacity it always should have had — the same roof repairs and waterproofing and HydroSeal HF systems we deliver across Gauteng.
