Roofs wear down over time due to aging and exposure to harsh weather conditions like hail, wind, heavy rain, and sunlight.

This is when we come in. As roofers with years of experience, one of the most frequently asked questions we get to hear is, “How long does it take for roofers to replace a roof?”

 3 days maximum. It only takes up to a day for small houses, but this time-range factor depends on certain things that I will discuss soon. It is good to replace your roof on time before the damage deepens. I hope you understand what I mean. 

Let’s discuss how to know when your roof needs replacement!

There are multiple things like does your roof leak? Or, how old is your roof? For asphalt shingles, up to 25 years is okay, while metal roofs can age up to 50 years. So, if you think your roof has crossed the age limit, it’s “REPLACEMENT TIME”.  

This might surprise some, but your high energy bills may signify poor roof insulation. 

Other things like obvious cracks or wear and tear in your roof mean it needs replacement.

How Long Does It Take To Reroof  A Roof?

The exact time taken to replace a roof can only be told by knowing what your house looks like. But based on our experience working with different houses, the average time is 1-3 days.

Multiple factors such as roof size, material, damage extent, and potential decking replacement contribute to the time needed for roof replacement.

Here is a small chart showing the time taken for the reroofing of different materials:

Types of Roof MaterialsTime Taken for Replacement
Asphalt shingles3-5 days
Metal roof1-3 days
Clay or Concrete 8-9 days
Slate roof6-7 days
Wood plates3-4 days

Factors Affecting The Roof Replacement Time

1. Size of the Roof

This is very easy to understand. The larger your roof is, the more time it takes to be reroofed compared to smaller houses. 

2. Any Complications

Complexities and complications on your roof may also lengthen the time taken to replace your roof.

Architectural factors like dormers, skylights, penetrations, chimneys, vents, and the measure of how steep your roof is can affect the time taken. 

Factors Affecting The Roof Replacement Time

A more complex roof requires additional time for professionals to accurately calculate angles for the replacement process compared to simpler roofs.

3. Materials Used for Making the Roof

Another factor that greatly affects your time frame for reroofing is the kind of stuff used to make the roof.

Is it a metal roof? It will typically take 1 to 3 days, depending on the size.

For asphalt shingles roof replacement, it’s the same as a metal roof. In contrast, other materials like wood or tiles can take 6 to 7 / 8 days. 

4. What is the Weather Like?

Weather conditions are extremely important to keep in mind, too. During winter, your reroofing can take longer than in summer.

Why is that, you ask? The sun.

There is a lack of availability of sunlight during the winter or in cold weather. You know just how important the sunlight is for the sticking and adhering of literally anything. 

For instance, asphalt shingles require a suitable temperature of about 40 degrees to stick to the roof properly. Can you do that in winter? No.

Reroofing during the rain or snow is a stupid idea. You can do it, but snow and rain during roof replacement can cost you some extra hours. 

5. Availability of Materials and Labour

The unavailability of materials required for the process and the contractors to carry out the process can also affect the required time.

6. Damaged Roof Deck

During the roof replacement, the professionals usually check for any damage to the underlying decking. If the roof decking needs replacement, too, it will add to the total timeline of the project.

Roof Replacement Process

Some typical steps required for all types of houses are:


Brief and proper initial assessment: This step allows the professionals assigned to your roof replacement project to inspect your house. They determine what type of roof should be installed, what materials should be used, and whether the decking is safe.

And what lengths of the plates are appropriate. 

Tear off: Next, remove any damaged shingles or metal plates. If the decking is damaged, the crew will remove that too.

Installment:  New decking and roof will be installed in the third step.
