The top layer of shingles is called the attic shingles and is typically the strongest layer. The next layers are called the underlayment, the middle layer, and the ridge shingles. The attic shingles are the strongest layer of your roofing system, since they’re the most exposed to the elements. Generally, three layers are used on an installation; although, there are several instances where four or more layers may be needed. Click this Greenville roofing
Another popular type of roofing is rubber slate roofs. These roofs are made with a pressure-relieving adhesive, which makes them flexible enough to roll roofing seams for installing shingles and flashing. Rubber slate roofs also come in a variety of colors, styles, and textures. Because of this, they are used in areas with intense hail or where aesthetics are important.
If you have a lot of clay soil in your yard, you may want to consider roof tiles that are made out of clay as well. These clay tiles don’t need to be as flexible and they’re much more durable than most other types of roofing tiles. For instance, you can get them in a wide array of colors, but because they’re made out of clay, they hold up well against water runoff. The water then backs up and water seeps underneath the clay tile, compressing it, which then causes the tile to mold and form into a tight, non-sparkly appearance. Because they’re so durable, you can get them at a lower cost than some other types of roofing tiles.
