A leaky roof is a problem that every homeowner wants to be fixed as soon as possible. If you’ve started seeing any signs of wear on your current home’s roof, you have probably worried yourself over how long it will take to replace the roof. While re-roofing your home won’t be an easy snap of the fingers, the actual process isn’t as long as others might think, especially in the hands of a great roofing contractor.

Getting the right time estimate on the process requires taking several factors into consideration. Replacing the roof on a bungalow would definitely be quicker than getting the work done on a whole mansion. Here are a few things you probably need to take into account.

How Long To Replace A Roof

Type of Roofing Materials Used

You might want to replace the roof with one that’s exactly the same or maybe you’re looking into a whole new house makeover. The process can be different for different materials, with some taking longer. Replacing Asphalt Shingles on a 40sqm house would take about a day or two with a team of five. Under the same conditions, replacing a flat roof would take about 3 days while replacing wood shakes or steel sheets would take a day longer. Synthetic and Natural slates on a roof would take almost a week to replace while concrete tiles take longest, stretching over to a week and a half. Take note that these are all estimates on a 40 sqm house.

Size of the Roof

Bigger projects take longer. The same estimates above would probably be doubled if you are dealing with an 80 sqm house. How the roof is divided and sloped would also affect the process.

Roof Decking

This doesn’t factor in as much as the others, especially when you are only planning to re-roof damaged portions, but the roof deck is also an important aspect. Mainly when there is damage that needs to be repaired on a roof deck. It would be unsafe to simply put a new roof on top of a damaged structure.


Before going ahead with the roof replacement, checking the weather forecast for the next few days could save a lot of time. Roofing projects could be delayed by days, even weeks if a strong storm is coming just when you get started. It could also be a problem when you have just torn off the old roof, leaving your roof deck barren when heavy rain starts to pour. Expect necessary damage control to add more hours to the project time. Gainesville has the least rainfall in April, May, and November, so projects during these months might give you a better time frame.

Roof Replacement Process

When talking about replacing a roof, it can mean either of 2 things. First, a complete tear-off of the old, followed by the installation of a completely new roof. Second, a layover of new roofing materials on damaged areas. Your licensed roof contractor should be able to give you an assessment and recommendation based on the current condition of your roof. A layover takes less time and costs less. But a complete replacement has several long term advantages as well. Let’s go through the processes to help you picture out how the next few days might go.


The first thing you have to do is make a plan. Even when you’ve already identified what you want, you’ll need to go over it in more detail with your contractor. After an initial assessment of the roof, they have probably made their own to-do list as well. This preparatory phase is crucial to setting an effective and doable timeline for the project.

Old Roof Tear-off

If you’ve decided to do a full replacement, the old roof has to be completely torn off. This will need a sufficient amount of time, depending on the size of the roof and the old materials used. Some materials may take longer to remove to prevent causing any damage to the roof deck.

Structural Repairs

With your roof deck barren, you’ll be able to easily spot any areas that need fixing. Skipping out on necessary repairs will only cost more in the long run. And will require a whole new process of re-roofing after.

Deck Protection and Leak Barrier Installation

Before putting in the new roof materials, a few protective layers need to be put up. Mainly, a deck protection layer, an insulation layer, and a leak barrier should sit on top of the roof deck.

New Roof Installation

Now comes the time-consuming process of laying down tile by tile, or shingle upon shingle to put up the new roof. Depending on the material, house size, and the number of people on the team, the process could stretch from a single day to well over a week.


The last step of the entire process isn’t the installation of the last shingle on your roof; it’s when your entire house has been cleaned up, leaving no piece of the old roof, stray nail, or pieces of plaster astray on your property.
