In general, the roof of an average residence (3,000 square feet or less) can be replaced in one day. In extreme cases, it could take three to five days. Depending on the climate, complexity and accessibility of your home it could even take up to three weeks. A roof replacement project can range from a single day to two weeks.
Many different considerations will factor into the total project time. At Above Roofing, we do our best to estimate the time it takes to replace a roof properly. When it comes to outages, it is often common for many homeowners to ask - how long does it take to replace a roof?

All other conditions such as availability of materials, inspection time, weather, and so on have been considered favourably. The larger your house is, the longer it will take to replace the roof and vice versa. For homes that are less than 1200 square feet, expect installation to take a few days longer.

This is because homes with asphalt roofs that are in hotter areas may be more susceptible to thermal shock or heat-related problems that cause cracking, which can lead to premature roof failure. All roofs need care and attention, and not attending to your room means you will most likely replace it before its estimated life span. At best, water damage will occur to your home and property if the roof leaks; at worst, the entire roof collapses and destroys your belongings and can even put you and your family at risk.
