Today's question answered by roofing experts Ideal Construction:How long does it take to install a new roof?
Most residential roofs can be completed within 3 to 4 days. Small roofs may take as little as a day, while commercial roofs can take longer. Installation time varies based on the size of the roof and the weather conditions, since roofers can't work in rain or snow. There are also sometimes delays in material delivery and scheduling of necessary roof inspections. Many roofing contracts will address delays.
