Replacing a roof is a labor-intensive project and, depending on the type of roof, could take anywhere from a few days to 2 or more weeks. The time involved is substantially affected by the weather. Wind, snow, rain, or even just the forecast of bad weather and will slow the process considerably.
Another factor that affects the length of the project is the condition of the decking. Once the old roof is removed, damage to the wood and structure under the old roof may be exposed. Repairing this damage can extend the duration of the project.
For built-up roofs, removing and replacing the roof will probably proceed at a rate of approximately 1,500 square feet per day. For single-ply roofs, the rate is closer to 2,000 to 4,000 square feet per day. Careful planning and close project management can reduce some of the delays caused by bad weather.
