TO protect your building

Roofing offers first protection against volatile climates, so careful attention must be paid to roofing and waterproofing.

 

Roofing is not just about completing a design – it also offers first protection against harsh and volatile climates. Incessant rains, high winds, baking sun and hail batter outer shells of buildings, threatening their integrity.

The perseverance of water to find a point of ingress is astounding. Water finds the path of least resistance and slowly makes its way through roofs and down walls. The short-term damage can be devastating and result in costly repairs, while long-term damage can even condemn a building.

Therefore, according to the painting, waterproofing and construction company Indawo, careful attention must be paid to roofing and waterproofing in order to safeguard buildings.

Indawo’s managing director, Geoffrey Jäck, says: “Roofing structures have to be built strictly to specifications with a complete understanding of the risks buildings face.”

Waterproofing solutions are typically tailored for the specific roof design. Flat roofs need more complex solutions than steep pitch roofs and outer structures always need to be protected to avoid water ingress.

Jäck recommends a structured preventative maintenance plan to identify areas on the roof and outer structures that may be prone to water damage.

“A short-term plan can address areas of weakness while a longer-term maintenance strategy ensures consistent checking of the exterior of the building. This strategy should also address ongoing maintenance needs such as painting, wood and decking protection and proper installation of substructures,” he explains.

The following needs to be monitored continuously:
• Roof and roof edges
A roof has to be watertight and full protection is needed around flashings, gutters and all the way to the edges. One should check for discolouration, cracks, peeling or damp.
• Water damage
Locating the cause is often complicated and can be several metres from where the damage manifests. Roofing and gutter screws are ideal spots for water to penetrate. Small pools on a roof should be checked and the area repaired to provide run-off. Stains on ceilings indicate water damage while mould may just be the cause of insufficient ventilation.
• Roof weaknesses
Asphalt can erode and move in regions where there are extreme fluctuations in temperatures. Tiles break, roof sheeting rusts, asbestos is dangerous, technological advanced membranes can be damaged when installing substructures, and the list goes on.

“Managed maintenance is critical to ensure the safety of buildings and guarantees positive returns on investment,” Jäck concludes.
