How long does it take to replace a roof? In general, a typical house's roof can be replaced in a day (3,000 square feet or less). However, it might take three to five days in extreme situations. Weather, complexity, and access to your property might delay the process. MK Roofing & Construction has been servicing the Middlefield, OH area for over the years.
