Keeping your commercial roof in top condition requires regular maintenance, particularly in New Zealand’s climate. Commercial buildings across Auckland, Wellington, and surrounding regions are regularly exposed to heavy rainfall, strong winds, and high UV levels. Combined with large roof spans and specialised commercial roofing materials, these conditions can accelerate wear and increase the risk of leaks and structural issues if left unchecked. Regular maintenance not only protects your commercial roof but also extends its lifespan and helps prevent costly, unexpected repairs.
At Solution Roofing, our experienced commercial roofing specialists provide trusted roofing services. We understand the local conditions and compliance requirements that affect commercial roofing performance. Below, we share our essential commercial roof maintenance tips to help protect your business premises and keep your roof performing reliably for years to come.
Carry Out Routine Roof Inspections
One of the essential things you can do for a commercial roof is to have it professionally inspected on a regular basis. While visual checks from the ground can help spot obvious problems, only a trained roofer can identify subtle signs of wear, deterioration, or potential failure that could develop into serious issues.
Inspections should be performed at least twice a year, ideally in spring and autumn and after extreme weather events. These professional inspections can catch small problems early and save you stress and expense in the long run. Check out Solution Roofing’s detailed guide on the signs your commercial roof needs repair or replacement.
Ensure Proper Drainage & Gutter Maintenance
Blocked gutters and roof drains are one of the most common causes of commercial roof damage. When water cannot drain correctly, it can pool on the surface, increasing pressure on the roof structure and causing material breakdown. Regularly check for and clear debris from gutters, outlets, and downpipes to ensure water flows away efficiently. Proper drainage helps prevent leaks, corrosion, and premature roof failure.
Prevent Moss & Organic Growth
While New Zealand’s climate can nurture growth on the ground, it can also encourage moss to grow on roofs. On roofs, this can interfere with drainage and trap moisture against the roofing material. Ensure overhanging trees are trimmed back, keep surfaces clear, and consider treatments to discourage moss or lichen where necessary.
Repair Damage Before It Escalates
Minor roof damage may not seem urgent, but even small defects can compromise the integrity of your roofing system. Loose fasteners, cracked sealants, or damaged flashings can allow moisture to enter the building, leading to internal damage and costly repairs. Addressing issues as soon as they’re identified is far more cost-effective than waiting until major work is required.
Monitor Seals, Flashings & Penetrations
Commercial roofs often contain penetrations such as vents, skylights, and HVAC systems. These areas are particularly vulnerable because movement, vibration, and ageing sealants can create weak points. Regularly checking penetrations and ensuring all flashings and seals remain watertight is essential to preventing leaks and maintaining long-term roof performance.
Keep Detailed Maintenance Records
Maintaining detailed records of inspections, repairs, and maintenance work provides valuable insight into the condition of your commercial roof. This information helps with budgeting, insurance assessments, and future planning, especially when determining whether repairs or replacement will be required. A documented maintenance history also demonstrates responsible property management.
