Tile Roof Ridge Waterproofing & Repaint in Sasolburg

Location: Sasolburg, Free State
Service: Tile Roof Ridge Waterproofing & Repaint

A large tiled-roof property — a main house, a studio and a separate office building — needed urgent attention after years of sun, movement and weathering had taken their toll on the ridge cement across all three roofs. The valleys on the main house had also silted up and cracked. The property owner brought in an approved SealPro applicator to repair, waterproof and fully repaint close to 900m² of tiled roofing.

The problem

On inspection, the ridge caps on all three roofs were cracked, and in several places the fibre-cement filling was missing altogether — leaving open gaps at the ridge line where water could track straight into the roof structure. The valleys on the main house were blocked with debris and had loose, cracked tiles, a common failure point that lets water pool and seep under the tile courses instead of running off. None of this was visible from the ground, but up close the cracked joints and crumbling fill lines told the full story of a roof overdue for maintenance.

The solution

The applicator carried out a full ridge and valley remedial programme before repainting the entire tiled surface:

1. Rake out and re-fill — All 119 linear metres of cracked ridge cement across the main house, studio and office roofs were raked out and re-filled with fresh fibre cement to restore a solid, even base.
2. Prime the substrate — Each repaired ridge was primed to ensure the waterproofing membrane bonded properly to the substrate.
3. Waterproof the ridges — The ridges were reinforced and sealed using SealPro’s Stretch Seal ridge system, a flexible waterproofing membrane built to move with the roof rather than crack again under thermal expansion.
4. Repair and seal the valleys — On the main house, 12 blocked valleys were cleared, loose and broken tiles replaced or resealed, and the valley lines waterproofed to restore free water flow off the roof.
5. Prep and wash — The full roof area on all three buildings was thoroughly washed down to remove lichen, dust and loose material ahead of painting.
6. Two-coat roof repaint — The entire roof surface — main house, studio and office — was coated in two coats of Marley M22 Ultimo roof paint in Slate, applied by hand from ridge to eave for even, durable coverage.

The result

What was a faded, cracked terracotta roof is now a uniform, deep slate-grey finish across all three roofs, with every ridge and valley properly sealed against water ingress. The repaint refreshed the look of the whole property, but the ridge and valley waterproofing addresses the root cause of the original problem — cracked joints and blocked water paths — giving the homeowner a roof that’s protected for years to come, not just repainted over existing defects.

This is the kind of ridge and valley failure we see across older tiled roofs throughout the region: waterproofing that’s cracked or gone missing at the joints, quietly letting water into the roof structure long before a leak shows up inside.
