Metal roofs are becoming more and more popular because of their durability and energy efficiency. The wide variety of colors and styles available can mimic almost any other type of roof. Metal roofs can last between 40 and 80 years, much longer than other types of roofs. They're also resistant to fire, wind, hail, algae, mold, mildew and pests. However, homeowners still need to perform regular maintenance to keep their metal roof in good condition and take care of any damage before it becomes worse. An honest, experienced Stamford roofing professional can help people keep their roof in great shape for years to come.

Many metals can react with each other, especially when wet. This causes bimetallic corrosion. To avoid this problem, make sure to use compatible materials on a metal roof. Aluminum coated steel isn't compatible with copper, prepainted steel, galvanized steel or lead. Copper pipes shouldn't direct water onto metal roofing or gutters.

Some chemicals and types of wood can also cause corrosion. For example, cedar is acidic and can harm many types of metal roofs. Read your metal roof manufacturer's care instructions so that these materials can be kept away from the roof.

Debris that collects under flashings and roofing overlaps can also cause corrosion if not removed regularly.

After removing the cause of the corrosion, clean the roof by sanding away all the rust. However, severely corroded roofing will need to be replaced. To help protect the roof in the future, apply a zinc rich primer to the sanded areas and then paint the entire roof with galvanized iron primer and a top coat. A wide variety of colors is available, so homeowners can easily change the look of their roofs.

Most metal roofs can be walked on, but too much traffic can cause scratches and other damage. Walking on a roof is also dangerous without precautions like safety harnesses. To minimize the risk, inspect the roof from the ground with binoculars twice per year. Look for bent or lifted flashing, loose nails or screws, and damaged metal sheets or shingles. More minor damage can be repaired, but badly damaged shingles, sheets or flashing must be replaced. If needed, use a long window cleaning brush with soft bristles to remove debris. Trim trees near the roof to minimize branches and leaves falling on top of it. Nearby branches moving in the wind can also harm the finish of a metal roof or even cause more serious damage over time.
