Roof waterproofing in Bloemfontein

A leaking roof almost never fails everywhere at once. It fails at the details: ridge capping that has cracked after a hailstorm, flashings that have pulled away from a parapet, a valley where debris dams the water, a flat section where ponding slowly finds a hairline crack. Patching that one spot with a brush-on sealant buys a season at best — because the surrounding membrane is the same age, in the same sun, moving with the same thermal cycles.

That is why BloemGuard installs complete systems rather than patches. A system treats the whole waterproofing layer as one engineered assembly: preparation, repair, primer, reinforcement, membrane and a UV-stable topcoat, each product specified by SealPro for the surface under it and applied in the manufacturer's order.

Bloemfontein roofs work harder than most. Summer hailstorms crack tiles and ridge lines; day-night temperature swings of twenty degrees and more open and close every joint in the roof daily; high-altitude UV breaks down exposed coatings years faster than at the coast. The systems we install are chosen for exactly these conditions.

• HydroSeal HF liquid rubber — a high-performance, polymer-blended liquid rubber waterproofing coating. It cures into a seamless, flexible rubberised membrane with no joints, no overlaps and no weak points — expanding and contracting with the structure. Minimum two coats finish almost every system.
• StretchSeal Membrane — the detail reinforcement strip embedded at every corner, joint, flashing, screwline and penetration. The detail is where waterproofing succeeds or fails — StretchSeal is mandatory there, never optional.
• ArmTec HyperFlex — the crack-prevention system for flat roofs and concrete slabs: primer, ArmTec fibreglass mesh reinforcement and flexible membrane, finished with a UV-stable topcoat.
• RidgeSeal — the tile-ridge system: loose cement raked out, gaps re-bedded with Posi Screed, then three RidgeSeal reinforcement strips per ridge tile embedded in HydroSeal HF and sealed with three coats.

1. Inspect & quote — we walk the whole roof, find every failure point and quote the complete system, not the visible symptom.
2. Prep & repair — high-pressure cleaning, crack and tile repair, ridge and flashing remediation, rust treatment where needed.
3. Seal & reinforce — primer matched to the surface, then membrane layers with ArmTec mesh embedded at every joint, outlet and detail.
4. Topcoat & sign-off — UV-stable topcoat in your approved colour, a final walkthrough with you, and documentation for your records.
