Asphalt shingles are designed to withstand various weather conditions, making them a durable choice for roofing. They can handle heavy rains, strong winds, and even hail, which can be a concern in many regions. Most asphalt roofing manufacturers offer warranties ranging from 20 to 30 years, and in some cases, even longer with proper maintenance. This longevity makes the initial investment more worthwhile over time. When looking for asphalt roofing for sale, it is crucial to consider the product's warranty and longevity as key factors in your decision-making process.
