Regular Inspections

Schedule regular inspections of your flat roof, ideally twice a year, to check for signs of damage, wear, or deterioration. Look for cracks, blistering, pooling water, loose seams, and any other potential issues that may compromise the integrity of the roof.


Clear Debris

Keep the roof surface clear of debris, such as leaves, branches and rubbish, which can block drainage pathways and promote water ponding. Regularly remove debris to prevent water buildup and potential damage to the roof membrane. 


Maintain Drainage Systems

Ensure that gutters, downspouts, scuppers, and drains are clear of debris and functioning properly. Improper drainage can lead to water pooling, which can weaken the roof structure and cause leaks. Clean out debris and inspect for any signs of blockage or damage.


Address Ponding Water

Ponding water is a common issue with flat roofs and can lead to premature deterioration of the roof membrane. If you notice areas where water tends to pool, investigate the cause and take corrective action, such as adjusting the slope of the roof or installing additional drainage. 


Inspect Seals and Flashings

Check all seals, flashings, and penetrations on the roof, including around vents, chimneys, skylights and HVAC units, for signs of wear or damage. Sealant deterioration and loose flashings can compromise the roof’s waterproofing, leading to leaks and water intrusion. 


Trim Overhanging Branches

Overhanging branches can pose a risk to flat roofs, especially during storms or high winds. Trim back branches that hang over the roof prevent damage from falling limbs and debris. 


Address Leaks Promptly 

If you detect any signs of leaks or water damage, address them promptly to prevent further deterioration of the roof structure and interior of the building. Contact a qualified roofing contractor to assess the extent of the damage and make necessary repairs. 


In conclusion, proactive maintenance is crucial for preserving the integrity and performance of flat roofs. By following these tips and addressing issues promptly, you can prolong the life of your flat roof, minimise the risk of leaks and water damage, and protect your investment for years to come.
