In order to determine how long it takes to finish a roof replacement or tear-off project, the size of the structure and the square footage is the main factor. It is obvious that if the commercial building measures a thousand square feet it will be more time consuming than doing work on a home or an office – helpful hints!
The average re-roofing job will take a couple of days. We can usually reroof an entire 5,000-square foot building in two days, weather permitting.
Although some of the largest roofing companies are able to complete such a project in one day due to their 50-person crew, it is not advisable. A roofer should be capable of handling a 5,000 sq. ft. tear off project within two days.
Many contractors will use the phasing system to manage large projects. This means that, if a roofing job is larger than normal and requires more work than usual, only part of the roof per day will be torn away.
A phasing job involves tearing off a section of roof each morning. The same area is then covered during the day. After the first day of work, the seams are waterproofed. That marks the place where nighttime construction stopped. After the work is completed, it’s time to start the work the next day. The water seam that was just finished will be removed and the work for the next roofing section begins.
