How Long Does a Roof Replacement Take? 

If you’re considering getting a new roof put on your home, one of your first questions may be “how long does roof replacement take?” Generally speaking, most roof replacements should less than a week (typically 3-5 days). However, the exact answer isn’t always that cut and dry. Different factors can impact how long a roof replacement will truly take.

Factors that Influence How Long Roof Replacement Will Take

You’ll get a more exact time estimate once you’ve begun the new roofing process. To help you get a handle on how long the process may take, we’ve compiled this short list of factors that influence how long roof replacement will take!

Seasons and Weather

Here in the Coeur d’Alene area of Idaho, we can have blistering summers and cold, cold winters. Summer is peak season for roof replacement for obvious reasons – it’s less cold, less wet, and provides much safer working conditions for contractors. It is unsafe an ill-advised to do a roof replacement in freezing, wet or stormy conditions unless it is absolutely necessary. We want you to have the best result and for our crews to come home healthy and safe!

An asphalt shingle roof can take as little as one day to install. However, if it gets too hot, a sunny day can be as bad as rain for worker safety. If we get several days of extreme hot weather, roof installation may get pushed back in order to keep workers safe. We need to always consider the safety and health of our workers. We are like one big family and we have to look our for family!


It goes without saying that the size of your roof will impact the amount of time it takes to install a new roof. The average sized roof in the U.S. is roughly 1,700 square feet. If you have a significantly larger roof, it follows that it may take longer than it normally would to install a new roof.

Complexity and Pitch

Complexity and pitch are also a huge factor when it comes to roof installation. Since a higher pitch equates to more of a fall risk for contractors, it may take companies longer to complete a task so that employees can take their time and safely complete the job. It may also cost more depending on the contractor you go with, as that company may need to seek out additional safety equipment to keep worker safe. 

If you have a roof with many valleys and hips, your timeline may also get pushed back by a few days. 


All other factors aside, the type of roof you’re having installed will factor in heavily to how long installation actually takes. 

Asphalt shingles roofing systems typically take between 1 and 3 days to install.

Flat roofs can take almost up to a week (between 3 and 6 days). 

If you get your flat roof treated installation may take even longer.

Other Complications

There are other factors that may complicate and lengthen the roofing process. The presence of mold and mildew is one big factor. If a roofing crew begins to remove the old roof and discover extensive mold or other structural damage, it may take longer as any damage and health risks must be addressed before the new roof is put on.
