Roof shingles are actually the flat, or sometimes curved, tiles that are installed in an overlapping manner on roofs. The way these are placed creates a way for water to easily slide down. This avoids water pooling which can cause major water damage to your roof and your home. In terms of materials, roof shingles are manufactured from a diverse set of materials that have different costs, weights, strengths, colors, and styles. Depending on what your home’s architectural style is and what your personal preferences are, there are actually many different roofing materials that you can use.
