Seeing signs of rust and corrosion on your metal roof might have you searching the internet for a “roofing company near me” pretty quickly. Modern metal roofs used in residential buildings today are completely different from the usual ones you see on industrial buildings. These products may be metal but they are designed to look and feel like regular roofing shingles, only more durable and long-lasting.
Despite their advantages, however, metal roofs are not completely invulnerable. They can be prone to problems unique to their type. One such problem is galvanic corrosion. Let our expert roofers at Innovative Roofing & Siding, Inc. explain what galvanic corrosion is and give you tips on how to detect and avoid this issue.
Corrosion and Galvanic Corrosion
Metal roofs installed correctly by a skilled roofing contractor are normally coated with a protective layer that resists the most common causes of corrosion. These include moisture and, rarely, exposure to the sun’s UV rays. Galvanic corrosion is a special type of chemical corrosion that happens when two different metals come into contact with each other in the presence of an electrolyte such as water.
Avoiding Galvanic Corrosion
Most manufacturers disclose the composition of their different products and provide information about what other metals would pair well with their metal roofs. Consult your manufacturer’s website for more information about their roofs and the best types for use in different environments. For example, waterfront homes do well with aluminum roofs while for others, steel roofs like galvalume is preferred.
The Right Roofers
Metal roof installations are more technical than other types of roofs. When you search for a “roofer near me,” make sure you choose a contractor who is trained, certified and experienced in handling this type of roofing. Poor installation can lead to many problems, one of which is galvanic corrosion.
