The duration of a roofing project can vary widely depending on several factors, including the size of the roof, the type of materials used, the complexity of the project, and weather conditions. For a straightforward replacement of an average-sized residential roof using common materials like asphalt shingles, the work can often be completed in 2 to 4 days.

More complex projects, such as those involving high-end materials or the need to repair structural damage, can take a week or more. Weather plays a crucial role in scheduling, as roofing requires dry conditions.
