For residential asphalt roofing, you can get the roof installed in one to three days, although more extensive or complex roofs may take longer. The experience of the roofing company will also impact the timeline. Metal roofing and other types of roofing materials may require a longer installation time due to the additional steps needed on the job site for proper installation. It's important to note that inclement weather, such as heavy rain or high winds, can delay the installation process and may require rescheduling the work with the contractor. Unexpected issues, such as structural damage or mold, may require additional time and a niche contractor before the roofing contractors can complete the job.
