Asphalt shingles are a popular roofing material due to their affordability and ease of installation. The installation process involves several key steps to ensure durability and longevity. Initially, a pre-installation checklist is reviewed to ensure a safe and efficient roofing installation, which includes preparing the yard and the surrounding area, identifying staging areas for materials, and ensuring access to necessary tools and utilities. The roof is then measured to determine the area and calculate the number of shingle bundles needed, considering an additional 10 to 20 percent for overage and waste. Safety is paramount, so utilizing appropriate safety gear, such as a harness, hard hat, and work gloves, is crucial. The roof deck is prepared by installing protection and starter shingles at the edges, followed by the installation of the asphalt shingles, working methodically from the bottom to the top of the roof. The shingles are nailed into place, adhering to a specific nailing technique and following the manufacturer’s guidelines for shingle style and pattern. Finally, ridge shingles are installed, ensuring no part of the roof is exposed. This process, when executed correctly, provides a weather-resistant and aesthetically pleasing roof that can last for several years. Source.
