Tips to Enhance the Lifespan of Metal Roofing Systems
Schedule Regular Inspections—Twice a Year is Ideal
Just because metal roofs are durable doesn’t mean they’re invincible. Biannual inspections—ideally in the spring and fall—are key to identifying early signs of wear. Common issues to look for include loose or missing fasteners, signs of rust or corrosion, panel misalignment or damage, and deterioration of sealant around seams or penetrations.
Hiring a professional roofing company familiar with commercial properties in Ontario, CA ensures that nothing is missed during inspections. Local experts understand the environmental stressors unique to the region and can recommend preventative steps accordingly.
Clean Debris and Drainage Paths Regularly
Southern California’s dry weather can sometimes lead to accumulated dust, dirt, and plant debris on commercial rooftops—especially if nearby trees are shedding leaves. Over time, this debris can clog gutters, scuppers, and drainage systems, leading to pooling water and increased corrosion risk.
Make it a priority to remove debris from the roof surface and drainage areas every few months, clean gutters and downspouts—particularly after storms or wind events—and check for signs of standing water after rain, as this can accelerate deterioration.
Regular cleaning not only prevents corrosion but also helps detect small issues before they grow into larger, more expensive problems.
Apply Protective Coatings for UV and Moisture Resistance
Over time, the finish on metal panels can fade or degrade under prolonged exposure to sun and rain. Applying a protective elastomeric or acrylic coating every 10–15 years can significantly enhance resistance to UV rays, oxidation and rust, and thermal expansion and contraction.
These coatings reflect sunlight, reduce heat absorption, and create a moisture barrier—all of which help maintain structural integrity. In Ontario’s warm climate, this added protection can also reduce cooling demands on your building, supporting both durability and energy efficiency.
Monitor Fasteners and Seams for Movement
Metal roofs expand and contract with temperature changes. While they’re engineered to accommodate this movement, it can still cause fasteners to loosen or seams to widen over time. Left unaddressed, these small issues can lead to leaks and panel separation.
During regular maintenance checks, tighten or replace fasteners that have come loose, inspect the condition of sealants at seams, joints, and flashing areas, and ensure no panels are shifting or becoming misaligned.
Fasteners are often overlooked, but they play a critical role in keeping the roof watertight and structurally sound.
Keep Foot Traffic to a Minimum and Use Walk Pads
Foot traffic is often necessary during inspections, HVAC servicing, or roof maintenance—but it can also cause dents, scratches, or compromised panel connections. Installing designated walk pads protects high-traffic areas and guides technicians to safe, reinforced walking paths.
Additionally, ensure that anyone walking on the roof is trained or supervised to avoid damaging panels, avoids stepping near seams, panel edges, or flashing, and uses non-damaging footwear while following safe practices.
Reducing unnecessary foot traffic can preserve surface coatings and prevent structural weakening over time.
