How Long Does It Take to Replace a Home Roof?

Here at Energy Kingston Exteriors we get emailed all the time a familiar question: how long does it take to replace a roof? The second most common question is similar: how long does it take to repair a roof? Unfortunately, roof replacement doesn’t fall into the category of generic answers that fit lots of folks all the same time. Multiple factors can change the answer. For example, if the home has a very large footprint with multiple sections it will take longer than a home with just one main unit. A home that is a two or three-story building will require more equipment to deal with the higher level and work involved. A home with a cement tile roof will take longer than a home with the standard asphalt tile. So, when answering the question, it’s usually with another set of questions to get an idea what kind of home the job would entail.

The Time of Year and Weather

The first big variable is definitely going to be the weather. If the job is being done in the summer, it’s going to take less time than trying to replace a roof in the winter. Winter roofing generally has to deal with rain or snow or both as well as keeping the moisture out until the new roof can be put in place.

Materials Variability

As mentioned earlier, the type of tiles and shingles can make a big difference in work time. The easiest and most common roofing material tends to be the most common, asphalt shingles. These go on quick, but they have less durability and the related roof won’t last as long. From there wood shingles and then slate tiles take respectively longer, now doubling and tripling the time. Finally, concrete tiles take the longest, usually taking as much as eight to twelve days to complete a straightforward roofing job.

Structure Size

Simple dimensions drive more work. The bigger your home is, the longer it will take to complete a roofing replacement. There’s no rocket science involved with this factor. However, what a lot of people don’t pay attention to is that larger homes tend to have sharper angles as well. When roofers can’t easily walk and work on a roof, that requires more time and equipment to safely replace the roof. On the other hand, a shallow angle is a lot easier, but that requires more water protection material because water penetration starts to be more likely the longer it sits on a roof.

Vintage Significance and Landmarks

Some homeowners have the unenviable pleasure of having a home that is also a historical landmark. In these cases the roofing replacement has to follow a stringent set of requirements. That can extend the replacement time significantly, including additional permits and planning reviews.


How long does a roof last once replaced depends on the materials used and skill involved. Assuming the team is professionally competent and does a good job, a typical quality roof can be expected to last at least 20 to 25 years with basic asphalt shingle. On the other end of the spectrum slate and copper roofing can last close to 50 years without roof repair, but they obviously have higher cost to install as well. With any choice on roofing, one should also ask whether he or she will still be in the home by the time the new roof needs to be replaced as well. For example, there’s little sense spending an arm and a leg if the residency time expected is five or ten years at best.
