Roof Ridge Maintenance & Ridge Capping Repairs in Mossel Bay

SealPro manufactures the RidgeSeal capping waterproofing system, the only system built specifically to waterproof tile roof ridges long term, installed by our approved local applicator. Mossel Bay’s mix of retirement estates, holiday homes and working-town roofs all share one enemy: salt.

Why Mossel Bay ridge capping cracks and leaks
Mossel Bay’s mix of retirement estates, holiday homes and working-town roofs all share one enemy: salt. Metal corrodes at every fastener, tiled ridges grow moss and lose mortar in the damp, and flat slabs on sea-facing homes take wind-driven rain sideways. Ridge mortar is rigid; the roof underneath it is not. Day-night temperature swings and coastal storms work every ridge line until the mortar cracks, the capping shifts, and water tracks straight down the ridge beam into the ceilings of Mossel Bay, Dana Bay, Hartenbos, Groot Brak and Mossel Bay Golf Estate homes. Repointing with more cement fails the same way, because cement cannot move. The lasting fix is a reinforced, movement-tolerant membrane over the full ridge — and that is exactly what the RidgeSeal system is.
The RidgeSeal capping waterproofing system — step by step
Every product below is manufactured by SealPro Coatings and applied at factory-specified coverage rates — the same system, every property.
- Ridge inspection & preparationEvery ridge line inspected; loose mortar and debris removed and the substrate cleaned back to a sound surface, so the system bonds to the ridge and not to dust.
- PosiScreed fill + PenetrarEvery gap, cavity and open joint packed solid with PosiScreed, then bound and smoothed with Penetrar — one continuous surface down the full ridge, no voids for water to find.
- RidgeSeal strips in HydroSeal HFPre-cut RidgeSeal membrane strips pressed into a wet bed of HydroSeal HF rubberised waterproofing, overlapped and embedded along the full ridge — the complete RidgeSeal system, reinforced end to end.
- Encapsulation & colour-matched finishFurther coats of HydroSeal HF lock the strip inside a seamless rubberised membrane, then the ridge is overcoated with Renew tile roof paint to match the roof — waterproofed and invisible.

Mossel Bay ridge capping FAQs
My ridges were repointed two years ago and they’ve cracked again. Why?
Because cement is rigid and the roof moves. Every repointing job cracks along the same lines sooner or later. The RidgeSeal system replaces that cycle with a reinforced membrane that moves with the roof instead of fighting it.
Can you do just the ridges without repainting the whole roof?
Yes — ridge maintenance is a standalone service, and the finished ridge is colour-matched to your existing roof. Many clients do the ridges now and the full repaint when the roof is due.
Which roofs suffer most in Mossel Bay?
Unprotected metal — salt finds every fastener and cut edge. Our system converts existing rust, seals the laps and finishes with marine-tolerant topcoats.
