Time to replace your roof.

Being a homeowner comes with a lot of extra responsibilities. One of those many responsibilities is knowing when to replace the roof. In some cases, the roof replacement is done when it just looks degraded and in other cases, it occurs when the roof is damaged. How long does it take to replace a roof? The time to replace your roof depends on the type of roof and how big the roof is.

Let’s take a look below at some of the details involved with how long it takes to replace a roof.

How Long Does It Take

If you are needing an actual timeline to replace your roof, then you will want to talk to the roofing contractor. Keep in mind that the day the roofing contractor shows up is likely the initial demolition day. Typically, it takes a day to remove the old roofing materials. Then the next day, the roofing contractor team will begin to install the replacement roof. Additionally, the time that it takes to replace your roof, depends on the size of the roof and what damage has occurred to that roof.

Roof replacement depends on the type of roof that you are replacing.

What Affects My Roofing Timeframe

Always consider the square footage of the current roof to determine how long it will take to replace your roof. Let’s take a look at some of the timeline factors.

  • Damage – the damage to your roof and shingles will determine how long it will take to replace the materials.
  • Pitch – the steepness or pitch of the roof will determine how difficult it will be for a roofing contractor to replace the roof materials.
  • Roof Shape – the bigger the roof, the more materials are needed to replace it.
  • Weather – the colder and rainier it is the more likely it will take some time to replace the roof.
  • Materials – the type of materials that you need to replace the roof will also determine how long it will take. Replacing slate, shingles, or metal can vary in the time frame.
  • History – if a roof requires specific laws or building codes, it could take a lot longer to do a simple replacement.

What Is Different In Each Roof

Replacing your roof will carry a different timeframe depending on the size of the roof and the complexity of the roof. Keep in mind that roofs can be categorized by difficulty to replace and install.

  • Asphalt Shingles (easy)-can be completed in 1-2 days.
  • Metal (moderate)-can be completed in 2-5 days.
  • Membrane (moderate/difficult)-can be completed in 2-14 days.
  • Wood Shakes (moderate)-can be completed in 2-5 days.
  • Concrete Tile (difficult)-can be completed in 5-14 days.

When wondering how long it might take to replace your roof, consider the style or type of roof that you have. If it is a flat roof or a sloped roof, will determine how long it could take to swap out the old with the new. Also, consider switching your roofing styles if you are having to make a replacement.

How Much Does It Cost

The national average to replace a roof ranges from $9,000 to $15,000. In some cases, a natural disaster has occurred and in that case, your insurance company will be involved to assist. When it comes to replacing your roof, make sure to do your own research. For the most part, you are looking to spend $3.50 to $16 per square foot.

Other Recommended Maintenance

While replacing your roof, there are a few areas of maintenance you will want to think about for the future. One of those is moss on the roof. If you find moss growing on the roof, you can hose it off, kill it with a cleaning solution and add zinc strips to keep it from coming back.

Next, also while you are replacing your roof, check out this roof inspection checklist. The checklist will help you look for areas of repair, such as any exposed nails, missing tiles, or flashing to name a few. This is helpful for you during and after the installation process, as well as in the future.

Lastly, gutters are great to have on the home and they help with drainage in the yard. One of the types of gutters is seamless. Seamless gutters are created at your home, with no seams, and a custom measurement. If this doesn’t seem like your style, there are others to choose from.
