Aluminum, as a structural construction material, is lightweight, nonrusting and corrosion-resistant, making it a well-suited material for roofing purposes. Aluminum is also resistant to most chemicals and acids that attack galvanized steel and iron and causes premature roofing repairs and replacement.
Aluminum as a roofing material is becoming increasingly popular because of its malleability, durability and ease of installation. Like common asphalt shingles, aluminum comes in different designs, such as shingle, tile, shake and standing seam. Compared with other metal roofing options, it does not contain iron and is not going to rust. Although aluminum does corrode, its passive metal elements naturally form a tight, dense covering that serves as a barrier to moisture, protecting the metal from further oxidation and corrosion.
Aluminum is also lighter and easier to handle and install compared with stainless steel and galvanized iron. While weight may not be important when choosing roofing options, aluminum as a lightweight material eases up labor and may reduce labor cost. Unlike steel, it does not warp, burn or distort easily, allowing for steadier lapping of tiles, shingles or slates during application.
Aluminum absorbs less heat than steel and traditional asphalt shingles and also reflects heat better than other metals, thus helping in keeping the house cooler during hot summer days.
