Waterproofing & roof care in Pentagon Park
Contemporary homes with flat roofs, parapets and clean lines — protected by the reinforced membrane systems that architecture depends on.
Pentagon Park is one of Bloemfontein's newer prestige addresses, and its architecture shows it: contemporary homes with flat-roof sections, concealed gutters, wide parapets and crisp plastered lines. That aesthetic depends entirely on waterproofing that works — every one of those clean details is a membrane detail underneath.
Flat-roof homes here are now reaching the age where original torch-on and liquid membranes need renewal. Our overlay approach renews them without stripping: reinforced ArmTec HyperFlex systems over the prepared existing membrane, detailed into parapets, outlets and skylights.
Concealed box gutters are the other Pentagon Park signature — beautiful when dry, unforgiving when their linings age. We re-line them with reinforced membrane and check outlet sizing while we are in there, because an overflowing concealed gutter discharges straight into the house.

Local questions
Our flat roof is only 12 years old and already leaking. Is that early?
Not for highveld UV and thermal swings — original single-layer membranes here age faster than coastal equivalents. The good news: renewal by reinforced overlay costs far less than the original installation.
Water stains appear around our skylight after storms. The skylight itself seems fine.
It usually is — the membrane detail around it is the failure. Skylight upstands need reinforced detailing as part of the roof system, not a bead of silicone.
Can you match the crisp plaster finish when sealing parapets?
Yes — reinforced sealing is finished with coating systems that preserve the clean architectural lines. Protection should be invisible.
