A gleaming metal roof can be a crown jewel for any property, offering durability, energy efficiency and a modern aesthetic. But even the toughest materials need a little TLC to keep them in top shape. Regular maintenance isn't just about aesthetics; it's about extending the life of your roof and avoiding costly repairs. From clearing debris to checking for corrosion, a few simple steps can make all the difference. Explore our comprehensive guide on metal roof maintenance here at Metal Central and discover the secrets to keeping your roof looking great and performing at its best for years to come. 

Regular inspections 

Make it a habit to inspect metal roofs twice a year—spring and fall are ideal. Property owners should look for any signs of damage like dents, scratches or loose screws and panels. Catching and addressing these issues early helps prevent bigger problems down the road. If they find anything concerning, encourage your customer to contact their professional metal roofing contractor to get things sorted out. 

Clear debris 

Metal roofs should be kept clear of leaves, branches and other debris. These can trap moisture and lead to corrosion, especially in areas with heavy rainfall or high humidity. Property owners can use a soft-bristle broom or leaf blower to gently remove debris, paying extra attention to valleys and edges where debris tends to collect. Larger pieces should be cleared off promptly and may require a professional contractor to get involved. 

Clean gutters and downspouts 

Clogged gutters and downspouts can cause water to back up, damaging the roof and underlayment. Property owners should be encouraged to regularly clean their gutters and make sure downspouts are clear to ensure proper drainage. This is especially crucial in tree-heavy areas where leaves and seeds can quickly accumulate. 

Trim overhanging branches 

Overhanging branches can be problematic for any roof. They can cause damage if they fall, scratch the surface or drop debris like leaves, seeds or sap, which can harm the roof’s finish. Property owners should arrange to have any overhanging branches trimmed back to avoid these issues. If the branches are high up or the job seems risky, we always encourage property owners to contact their preferred professional for assistance. 

Check for rust or corrosion 

Although metal roofing from Central States is resistant to rust, it’s still a good idea for property owners to check for any signs of corrosion around fasteners, seams and bends. If your customer finds rust spots, they are advised to scrub them off with a wire brush, then apply a primer and paint designed for metal roofs to prevent further damage. Touch up paint is available to purchase from your local Metal Central location. 

Maintain proper insulation and ventilation 

Proper attic insulation and ventilation is crucial for roof longevity. Property owners can check for any issues like fallen insulation or signs of leaks and make sure roof vents are clear of debris. We recommend property owners consider hiring a contractor to inspect the attic space and vents at least once a year. 

Snow and ice removal 

For structures in a snowy area, ensure property owners understand how their snow guards work, if applicable and how to safely remove snow from their roofs. For safe snow removal, property owners can use a roof rake with a long handle but should make sure to avoid sharp tools that could damage the roof. 

Repairing damage or loose panels and trim 

If property owners notice damaged or loosening panels or trim over time, we recommend they contact a metal roofing contractor to determine if repairs or replacements are needed. It’s important to always use screws designed for metal roofing and if a screw is loose, replace it properly. 

Professional inspections and maintenance 

Consider having a professional roofing contractor conduct a thorough inspection and maintenance check every few years. They can spot potential issues early and take care of tasks like re-sealing seams or replacing damaged panels. A well-installed metal roof from Central States typically won’t need re-sealing, but it’s always good to double-check. 

Safety considerations 

Walking on the roof 

While metal roofs are sturdy, walking on them can still cause damage if not done correctly. For any roof access, we always recommend property owners hire a contractor who knows how to walk on metal roofs safely without causing harm. We advise contractors to use a properly secured ladder, walk only on flat portions of the panels and wear rubber-soled shoes for better grip. This is especially true for steep roof applications and contractors should always use appropriate fall protection. 

Protective gear 

For anyone working on the roof, using personal protective equipment (PPE) like gloves and safety glasses is crucial, especially during repairs or debris removal. 

Weather and roof structure 

Check the weather before accessing a roof. Avoid walking on a wet or slippery surface and be mindful of any structural issues that could pose risks. 

A final word 

By following these maintenance tips, your customers can keep their metal roof looking great and performing well for many years. Metal roofing is generally low maintenance, but taking these steps is key to preserving their investment.
