Shingles are the most common roofing material in North America. They can be made from a wide variety of materials, such as slate, plastic, and composites, but they are most commonly made out of asphalt. Each roofing shingle is small and rectangular. When installed, they overlap to keep out water. Asphalt is used because of its waterproof properties. They’re popular because the up-front cost is relatively low, and the installation itself is fairly easy and straightforward for professional roofers. When homeowners on a budget compare tile roofs vs. shingle roofs, they often choose shingles because of the price. Roofing shingles come in a variety of shapes, textures, and colors, making them architecturally versatile. They reflect sunlight well, which is an advantage in hot climates, and they’re also designed to resist both, fire damage and algae growth. They can deteriorate from moss growth and accumulated debris, so shingle roofs need to be cleaned with specialized solutions.
