<p>Sheet metal includes galvanized, fiberglass, or plastic sheets.</p>
<p>The fiber cement sheet is a sheet made from cement, sand, and mineral or synthetic fibers.</p>
<p>If the answer is that the roof is tile, verify that it is the basic material and not the covering or decorative material.</p>
<p>Take into account that the waste material includes pieces of cardboard, rubber, tires, etc.</p>
<p>If they answer that the roof is constructed from two or more different materials, ask which covers the greater part. If they are in the same proportions, choose the first one that appears in the answer options.</p>
