Metal roofing systems are renowned for their longevity, resilience, and aesthetically pleasing look. With proper care and maintenance, a metal roof can easily last 50 years or more, providing a fantastic return on investment. At SHI Roofing, we believe that homeowners can maximize the benefits of their metal roofs with proper knowledge on care and cleaning. Here’s a comprehensive guide for you.
Regular Inspection:
- Twice a year, preferably during spring and fall, give your roof a thorough check. This is to identify any issues that may have developed such as loose fasteners, seam separations, rust spots, or accumulated debris.
- After major storms, always check for any damage, especially if there were hail or strong winds. Metal roofs are sturdy but they aren’t impervious to extreme weather.
Cleaning Debris:
- Remove leaves, twigs, and other debris that may have settled on your roof. Accumulation of such debris can trap moisture, which might lead to corrosion over time.
- Gently use a broom or soft brush to sweep away debris. Always sweep in the direction of the panel seams to avoid causing any damage.
Washing the Roof:
- Use a mixture of water and gentle detergent. Avoid abrasive cleaners as they can damage the roof’s protective layer.
- For mildew or fungal growth, you can add a small amount of bleach to the cleaning solution.
- Use a soft-bristle brush or a non-abrasive sponge to scrub off any stubborn dirt or stains.
- Rinse the roof thoroughly after cleaning to ensure no residue is left behind.
Addressing Stains and Streaks:
- For stubborn stains such as those caused by water runoff, consider using special metal roof cleaning solutions available in the market.
- Be careful with power washers. If you choose to use one, ensure that it’s on a low-pressure setting. High-pressure washes can damage the roof’s protective coating.
Check Gutters and Downspouts:
- Keep them clear. A clogged gutter can lead to water pooling on your metal roof, potentially leading to rusting and other damage.
- Inspect for rust. If you find any, it’s essential to treat it promptly. Use a wire brush to gently remove rust, then apply a primer and paint to seal the area.
Minor Repairs:
- If you notice loose fasteners, missing screws, or small areas of damage, address them promptly. Small issues, if left unchecked, can lead to significant problems in the future.
Re-coating and Paint:
- Over time, the protective coating or paint on your metal roof might wear off. Consider re-coating or repainting every few years to maintain the roof’s look and protective layer.
Professional Inspection:
- Sometimes, it’s worth having a professional roofer from trusted companies like SHI Roofing inspect your metal roof. They can identify potential problems that may not be apparent to the untrained eye.
