Your roof won’t last forever. After some decades you’ll have to replace your roof.
This can happen earlier than expected if your roof has been damaged.
How long does a roof last?
A roof can last for anything between 20 and 50 years, depending on its materials.
If you have to embark on the journey of removing your existing roof so that you can replace it with a new one, you’re probably wondering how long it will take. Here’s what you need to know.
How Long Does It Take To Replace A Roof?
Usually, replacing a roof takes up to a day for the average-size residence. However, if the job is complex or there are bad weather conditions, this could result in the job taking a bit longer – you’re looking at a few days.
The amount of time it takes to replace your roof varies depending on the roofing material you’ve got. Let’s take a look at different roofs and how they affect the time it takes to have your roof replaced.
This type of roof shingle is very common and since roofers are used to working with it, this makes asphalt shingles easy to replace. You would have a new roof within a day or two, which is pretty neat.
Note that it’s a good idea to remove your old or damaged shingles before you put new asphalt shingles on the roof, as this will prevent the roof from becoming too heavy.
If you have a metal roof, you won’t have to worry that it will take long to replace it – you’re looking at approximately one or two days for your new roof to be installed. Weather will affect the duration of installation – if it becomes wet or windy then there will be delays. Bear in mind metal is very slippery when wet, so you want dry, warm conditions for the installation.
If you have concrete roof tiles that need to be replaced, you can expect this to take between six and nine days so it’s a lot more than what you’ll experience with some other roofing materials. The reason for this is because of how heavy concrete tiles are to work with.
While you might not think of vinyl for your roofing material, this is actually very durable and it’s used in applications such as roofing, flooring, and siding because of how it’s resistant to both wind and fire.
A vinyl roof is referred to as a PVC membrane roof and it keeps homes cool, which helps to increase energy efficiency. Generally, a PVC roof installation won’t take many days because its installation is straightforward.
Wood shake roofs can take around three or four days to replace. Just bear in mind, however, that manufacturers of cedar shakes don’t keep this material in stock. Instead, the shakes are made to order, so you can expect to wait up to two months for them and this should be considered before you choose to install a cedar shake roof.
A rubber roof will take about a day or two to be replaced. This is because the material is lightweight, so it’s easier to install. What further helps is that the roofing contractors will place the rubber membrane on the roof in large sections, which quickens the installation time.
How long it will take to install slate shingles will vary depending on whether you’re installing natural or synthetic shingles. Natural shingles can take between six and seven days to install, whereas synthetic ones take much less – approximately three to five days. This is because they are much lighter than natural slate shingles.
Roof Replacement: What Are The Pros?
There are several benefits linked to replacing your roof. These include:
It can save you money
While you might think you can save money by repairing roof damage, you could end up spending a lot of money that could have gone to replacing the roof instead. It’s worth considering if the major roofing repairs you have to complete will increase the longevity of the roof, and by how much.
It increases the roof lifespan
Replacing your roof can help you to extend the lifespan of your roofing system. A new roof can last for decades! Roof replacements usually have limited lifetime guarantees attached to them. As for roofing repairs, these don’t increase the roof’s lifespan as they’re temporary.
It makes your home look new
Replacing your old or damaged roof with a new one can completely change the look of your home for the better.
What Are The Cons?
Of course, there are some potential drawbacks associated with replacing your roof. Let’s take a look at some roof replacement cons.
It can be expensive
Replacing your entire roof instead of repairing it or choosing to reroof, will be the more expensive option. Generally, a roof replacement can cost you between $5,500 and $11,000, but this depends on the square footage of the roof and the type of roofing material that you want.
It can result in upheaval
If a roof replacement takes a few days to be completed, this can lead to upheaval in your living conditions even though you probably won’t have to leave your home for the duration of the roof-replacement process.
Signs That You Need To Replace Your Roof
To be sure that replacing your roof is really required and you can’t just get away with making roofing repairs, there are some important signs to look for that show you have to replace your home’s roof.
Your roof is sagging
If your roof is sagging this can cause serious damage to your home, such as moisture accumulation, leaks, and rotting boards. Of course, sometimes a sagging roof can be repaired, but if the damage has been extensive then you will have to replace the roof.
Your roof is showing signs of damage
While you can replace some specific shingles that are damaged, if there’s widespread damage across your roof this warrants a roof replacement. Other things to look for include cracked, curled, or loose shingles; discoloration or other damage around your vents; and extensive algae and moss growth.
Your attic is displaying problems
When you’re in your attic, inspect it for daylight that’s streaming through the roof boards and any signs of water damage, such as in the form of water stains on the roof boards. Both of these show that your roof is not giving you the correct insulation.
Your roof decking is damaged
The roof decking is the structure at the base of the roof. It supports other components of the roof’s construction, such as the shingles and underlayment.
If the roof decking has been damaged, such as because water has managed to seep through the shingles to the decking, this usually shows that there is damage in other components of the roof, so it’s a sign that you should replace the entire roof.
Your roof has two or more shingle layers
Instead of replacing your roof, you might prefer to save money by installing shingles over your existing shingles. While this can be a viable solution, if you’ve already got two layers of roof shingles, you need to replace the roof.
A roof can’t tolerate the weight of more than two layers of shingles, and reroofing doesn’t deal with any problems experienced by the roof – it just covers them up temporarily.
What factors affect how long it takes to replace a roof?
A roof tearoff and installation can take different amounts of time, which depends on factors such as the condition of the existing roof, the size of your roof, and the weight of the new roofing materials.
Does it take longer to replace a steep-slope roof?
A steeper roof can take longer to replace and install than a flat roof. This is because it has more structures and components, such as hips, valleys, and various angles.
If you need to replace your roof, you’ll naturally have some questions you want answered. These include, “How long does it take to replace a roof?” which we have looked at in detail.
Whether your roof is severely damaged or reaching the end of its lifespan, you should consider replacing it so that you can breathe new life into your home and roofing system, and keep potential problems at bay.
