Metal roofs cover a lot of Pretoria East: patios and carports, outbuildings on the Mooikloof smallholdings, workshops, double garages and whole houses. IBR and corrugated sheeting is tough, but it moves. Every hot day it expands, every cold night it contracts, and over the years that movement works screws loose and opens the overlaps.
Where IBR roofs leak
- Screw fixings: perished washers and screws that have backed out leave a hole in every sheet.
- Side and end laps: wind-driven rain is pushed up and under overlapping sheets.
- Flashings and ridges: where sheets meet walls, the ridge capping or a change in pitch.
- Rust: starts at cut edges, scratches and fixings, especially where gutters hold water.
- Gutters and box gutters: blocked by leaves, overflowing back into the roof space.
How we do IBR roof waterproofing
For IBR roof waterproofing Pretoria jobs we clean the roof, treat rust, then re-seat or replace fixings. Laps, ridges and flashings get a waterproof coating reinforced with membrane fabric so the seal can flex with the sheet. Where the whole roof is tired, a full-coverage reflective coating adds a long-lasting waterproof skin and cuts heat build-up under the roof.
Asbestos roof repairs Pretoria homeowners can do safely
Many older Pretoria homes and outbuildings still have asbestos-cement (fibre-cement) sheets. Don't drill, cut, sand or high-pressure clean them: that releases fibres. For asbestos roof repairs Pretoria owners can stay safe with, the usual approach is encapsulation. The sheets are left in place and sealed with a suitable coating, and leaks at fixings and laps are repaired without breaking the sheets. If sheets are broken or need removal, that must be done by a registered asbestos contractor under South African regulations. We'll tell you which situation you're in.
Not sure what your roof is?
Send a photo with the quote form. Grey, wavy sheets on an older building are often fibre-cement; we'll confirm before any work starts.
Repair or replace?
If the sheets are sound and rust is surface-level, waterproofing costs a fraction of re-roofing. If sheets are rusted through in many places, replacement is the honest answer, and we'll say so. For leaks you need stopped now, start with roof leak repairs.
