Regular Maintenance Makes a Big Difference
Clean Your Metal Roof the Right Way
Metal roof cleaning is a key part of upkeep. Leaves, dirt, and debris trap moisture and cause stains or mold.
- Use a soft brush or low-pressure washer.
- Avoid harsh chemicals—mild detergent and water work best.
- Clean gutters often so water flows away from the roof.
A clean roof performs better and looks better, too.
Prevent Rust on Metal Roofs
Rust can sneak in through small scratches or standing water.
- Inspect for scratches after storms.
- Apply touch-up paint or sealant to exposed spots.
- Check fasteners—loose screws may cause leaks and rust.
Keeping metal dry and sealed helps stop rust before it starts.
Recoat for Extra Protection
Recoating metal roofs adds a new waterproof layer and boosts energy efficiency.
- Recoat every 10–15 years or when the current coating fades
- Choose reflective coatings to reduce heat buildup
- Fix cracks and clean the surface before applying
Think of it like sunscreen for your roof—block UV and moisture damage.
Spot Small Problems Early
Schedule Regular Roof Inspections
Routine roof inspections in Kennewick help catch minor issues before they turn into major repairs. During an inspection, it’s important to check the flashing, vents, and seams for any signs of damage. Homeowners should also look for gaps, rust spots, or loose panels that could compromise the roof’s integrity. It’s especially crucial to inspect the roof after wind, snow, or hail events to ensure any weather-related damage is addressed promptly.
All City Roofing can do a full inspection and let you know what’s needed.
Fix Small Repairs Right Away
Loose fasteners, bent panels, and slight leaks are easy to fix—as long as you act quickly. Small gaps can often be sealed with the right sealant, preventing moisture from getting in. Damaged panels should be replaced promptly to maintain the roof’s strength, and securing loose edges is essential to avoid wind-related damage.
Timely repair saves your roof—and your wallet.
Standing Seam Roofs Need Special Care
Standing seam roofs feature vertical panels and hidden fasteners, offering a sleek and durable roofing solution. To keep these systems performing well, it’s important to maintain clear drainage paths that prevent water buildup. Edges and joints should be properly sealed to stop potential leaks, and because the fasteners are concealed, it’s wise to hire a professional to inspect these areas and ensure long-term reliability.
They’re tough—but they still need proper care to last.
