Metal roofing systems offer homeowners many benefits. They have the potential to last for up to 80 years with regular maintenance, are highly durable, and reflect solar heat to keep your cooling costs low. To keep your roof in great condition, it’s crucial to clean the surface periodically. Below is a guide explaining how to keep it tidy.

Why You Should Clean Metal Roofing

All roofs are vulnerable to accumulating debris over time, including dirt, grime, residue from saltwater, animal droppings, and other general buildups. Although it’s less likely to occur on metal, shaded areas that are cooler and more prone to holding moisture could also encourage moss and algae to thrive. Neglecting to clean the surface leaves it susceptible to long-term damage that reduces its integrity and lifespan.

Exposure to moisture and air can also encourage the metal to corrode with time. A bit of rust won’t harm the integrity of your metal roofing system, but maintaining the surface can prevent accumulation and discoloration. If you want to upgrade your roof with a protective coating that safeguards the surface from rust, inclement weather, and potent ultraviolet rays, the surface must be cleaned first to ensure the product adheres properly.

How to Clean the Surface Safely

Always proceed with caution when cleaning metal roofing. If possible, hire a professional or work with a partner for security. Before you begin, inspect the surface carefully and make note of areas that are corroded or appear degraded. Avoid those areas, as they may be hazardous to walk on or have sharp points that are unsafe to navigate. Look for algae, dirt, and grime that might need more attention, too.

Use a garden hose to rinse minimal buildup off the surface. For a deeper clean, add a quarter cup of mild dish detergent to a gallon of water, mix, and apply to affected areas. Wait at least 10 minutes before rinsing off with the hose.

If moss or algae is present, have a professional assess the area since it’s best not to use aggressive cleaners, like pressure washers, steel wool, and wire brushes on metal. They can advise you on the most appropriate cleaning solution based on the degree of buildup.
