Let’s be honest—roof maintenance isn’t usually top of mind until something goes wrong. But in London, Ontario, where icy winters, heavy rains, and summer heatwaves can put serious strain on your home, staying ahead of roofing issues is key. If you’ve invested in a metal roof, you’ve already made a smart choice—it’s one of the most durable, long-lasting materials out there. Now, it’s just a matter of keeping it in top shape.
At AM Group Exteriors, we help London homeowners protect that investment with practical, seasonal maintenance. Here’s your go-to checklist for metal roofing upkeep—simple, effective, and built for our local climate.
Metal roofs are known for their exceptional durability, energy efficiency, and long-lasting performance—often holding up for 40 to 70 years. But even the strongest roofing systems need occasional care to stay at their best. With the unpredictable weather in London, Ontario—from harsh winters to damp springs—routine maintenance is key to avoiding rust, loose fasteners, seam issues, and other weather-related damage.
Ignoring small signs of wear can lead to bigger problems, like leaks and reduced insulation performance. The good news? Staying proactive doesn’t take much—and it pays off big in the long run.
The Ultimate Maintenance Checklist for Metal Roofs
1. Book a Professional Roof Inspection Once a Year
Even though metal roofs are low-maintenance, it’s smart to schedule a professional inspection annually—ideally in the fall. This gives you time to catch any issues before snow and ice arrive. A certified roofing contractor in London can spot things like early corrosion or installation concerns that you might miss.
Pro Tip: After a major windstorm or heavy snowfall, consider an extra inspection just to be safe.
2. Do Seasonal Visual Checks Yourself
Each season, take a few minutes to walk around your home and check the roof from the ground—or from a safe, stable ladder. Look for:
- Missing or loose fasteners
- Bent or lifted panels
- Rust around flashing and seams
- Cracked or deteriorated sealant near vents and skylights
- Debris build-up in valleys or behind chimneys
Catching these signs early helps prevent small problems from becoming expensive ones.
3. Keep Gutters and Downspouts Clear
Metal roofs are great at shedding water, but that water needs somewhere to go. If your gutters are blocked, it can back up onto your roof or even affect your foundation. Clean your gutters every season, especially after the fall leaf drop or heavy spring rain. If water isn’t draining correctly, it may be time to contact a specialist in roof repair in London, Ontario.
4. Inspect the Interior for Warning Signs
It’s not just the outside of your roof that matters. Head up to the attic or top floor and look for:
- Water stains or damp insulation
- Rust on exposed fasteners
- Signs of poor airflow or excess condensation
Ventilation and insulation are essential for preventing long-term issues like mould and internal corrosion.
5. Trim Nearby Trees and Branches
Overhanging branches can scratch or dent your roof, especially in high winds. Trim back any trees near your home to prevent physical damage and reduce the amount of debris collecting on the roof. This also makes routine maintenance much easier.
