Just Sample Text (Needs to be changed): Vinyl, aluminum, steel and copper are some of the materials that gutters and downspouts are made of. Vinyl is great for do-it-yourselfers and can be found at home-improvement centers. Aluminum gutters are the most common. Primary aluminum is the thickest and most consistent kind. Avoid secondary aluminum, a recycled product thats often plagued by inconsistent thickness. Metal gutters are made in sheet metal shops and require gutter specialists to install them.
