Re-Roofing Vs Roof Replacement

Two processes are used for the maintenance and repair of roofs: re-roofing and roof replacement. 

When a new layer of roofing material is applied over the existing coating, it is called re-roofing, and when the existing material is completely removed and replaced by new materials,  it is called roof replacement. 

When your roof is in good condition, the best option is re-roofing, not roof replacement. However, if your roof is old or damaged due to a recent storm, then a roof replacement is the best option. 

But do not get dizzy. We are here to help you find the best way to maintain your roof. 

Is Roof Restoration Better Than Roof Replacement? 

This depends on the current conditions of your roof, including how old or damaged it is. If your roof is in good condition and serviceable, you can opt for a restoration instead of a replacement, weighing the roof replacement cost. 

On the contrary, if your roof is almost out of service because of age or some severe damage, you may need a roof replacement.

But how will you know which one is a viable option for you? Well! You need an inspection by a roofing professional to assess the extent of any damage and find out whether restoration or replacement is better for you. 

Tips! Early inspections and proactive maintenance can extend the lifespan of your roof. 

What Is Re-Roofing?

Re-roofing is the process of applying a new layer of roofing material over the existing layer. It is an alternative to roof replacement, which involves the complete removal and replacement of existing roofing materials. 

For instance, re-roofing a shingle roof involves employing a second layer of shingles on top of the existing one. 

Pros & Cons Of Re-Roofing

Pros 

• Re-roofing saves you a lot of money.
• It also does not require a lot of labor and time because the existing roof does need to be torn off. 
• It also saves you from roofing materials.
• It is a more convenient and efficient way for homeowners to restore their roofs. 

Cons

• Re-roofing is less durable than roof replacement.
• It is not recommended for metal roofs. 
• You might not spot the existing damage or leak when a new layer is applied over it. 
• In many residential areas, it is prohibited to apply a third layer of shingles if you already have two. 

What Is Roof Replacement?

Roof replacement is the process in which the existing material is completely removed and replaced by new materials. It is a recommended process when your roof is too old or has heavy damage, which often leads to questions about how often to replace roof.

Sometimes, your roof becomes inoperable due to age or a storm, causing severe damage. In this case, professional roofers recommend replacing it.

Pros & Cons Of Roof Replacement 

Pros

• It is more durable.
• It saves money in the long run. 
• It can be done irrespective of the layers of a roof. 
• You can fix the underlying issues in your roof because they involve the removal of the existing roofing materials. 

Cons

• It is expensive and costs you a lot of money. 
• It needs a lot of time.
• It also needs more labor than re-roofing. 

Warning Signs You Need A New Roof

Your roof shields your home from the elements throughout the year. But time or lousy weather can damage it. Therefore, you should look out for warning signs that indicate you need a new roof. 

These signs include:

1. Visible Signs Of Wear And Tear

Visible signs of wear and tear on your roof are a significant warning sign that a new roof might be necessary. These signs indicate that your roof is not performing its job effectively. 

They can result from aging materials, harsh weather, or simply normal wear and tear. By spotting these signs early, you can address potential problems before they turn into leaks or more serious damage.

2. Signs Of Moisture

Signs of moisture can indicate the need for a new roof, much like when deciding between Asphalt vs Fiberglass Shingles. Therefore, watch out for leaks, stains, or even mold growth—all signs that water is finding a way in. 

If left unchecked, this moisture can lead to rot, weaken structural supports, and even cause your roof to sag. Then, you will need a whole new roof.

3. Age Of The Roof

Every roof has an expected lifespan. Weather and other elements eat away at their strength with time, and after the expected lifespan, your roof does not work correctly. 

Then, you will need to have a new roof. 

If your roof is too old and you neglect it, it can cause severe damage to your property and family because it can collapse after the expected lifespan. 

4. Sagging Roof

A sagging roof is a warning of the need for a new roof. 

Roofs get old and weak over time, just like anything else, and make them more prone to sagging. Even too much weight from snow or debris can cause dips. Ignoring a sagging roof is trouble.

Thus, a sagging roof indicates that it is time for a change. 

5. Warped Or Rotting Decking

Your roof deck plays a vital role in keeping your home safe and dry. But what happens when the deck itself becomes warped or rotten? 

It is a big warning sign that your roof might need more than just a shingle replacement—it might need a new roof.

What Is The Difference Between Re-Roofing And a New Roof?

Re-roofing means when a new layer of roofing material is applied over the existing layer without removing it. A new roof means the removal of the existing roofing material and the application of a new roofing material. 

There are some differences between re-roofing and a new roof. These include: 

1. Re-roofing vs Roof Replacement Cost

The cost of re-roofing is less than a new roof or roof replacement. Re-roofing does not involve the removal of the existing roofing material. Therefore, labor has a little cost. 

Roof replacement requires the complete removal of the existing roofing materials, which costs more in terms of labor. However, re-roofing is cheaper than roof replacement. 

2. Process

The process of re-roofing is simple compared to roof replacement.

Re-roofing does not require the removal of the existing roofing material; instead, roofers install the new layer over the existing one, often considering options like the Best Roof Shingles For Florida for durability and efficiency.

The process of roof replacement is somewhat complicated. It involves first removing the existing roofing material and then applying the new one.

3. Installation Time

The exact time of the installation depends on the size and style of your roof. However, re-roofing takes less time than roof replacement. 

Re-roofing does not require removing the older layer, so it saves time. Conversely, roof replacement requires more time because laborers need to remove the older layer first and then install the new material. 

4. Number Of Roof Layers

Your roof’s maximum number of layers depends on the type of material you use. 

For instance, you can re-roof a metal roof because you cannot apply one metal layer over the existing one.  Shingles roofs and flat roofs can withstand two layers. So they can be re-roofed very quickly. However, many residential areas do not allow having a third layer on your roof. 

But if your roof has already been re-roofed or is a metal roof, you can have it replaced, which generally involves a single layer. 

5. Underlying Issues

One main difference between re-roofing and roof replacement is the fixing of underlying issues. 

The existing layer is not removed when the roof is re-roofed, so the underlying issues cannot be identified and fixed. 

On the other hand, in roof replacement, the existing layer of roofing material is removed, and underlying issues can be identified quickly and fixed. 

6. Life Span

Roof replacements have a longer lifespan than re-roofing. Most new roofs last 20 to 30 years with protection and even longer in some situations. However, re-roofing projects last up to 15 years.

So, the lifespan of a roof can be a factor to consider when changing your roof. 

Factors to Consider When Choosing Between Re-Roofing and Roof Replacement

Certain factors influence the decision to re-roof or replace a roof. These factors should be considered when choosing between them. 

These factors are: 

1. Age and Condition of The Existing Roof

The age and condition of the existing roof are basic factors to consider when choosing re-roofing or roof replacement. 

If your roof is too old or too damaged, you should opt for roof replacement, but if it is in good condition and serviceable, you may choose re-roofing. 

2. Budget Constraints

Your budget can be a factor that will consider whether to choose re-roofing or roof replacement. 

A roof replacement needs more money in terms of laborers’ expanses. Contrary to this, re-roofing requires less money because it involves less labor. 

So, if you are short on your budget, go for re-roofing. 

3. Long-term Goals for the Property

Re-roofing lasts no more than 15 years, while a roof replacement lasts 20 to 30 years or even more.

If you are planning to maintain your property for the long term, roof replacement is the best option. Otherwise, you may opt for re-roofing. 

4. Environmental Factors

You should also consider your environment as a significant factor in your roofing decision. If you live in a harsh and stormy climate, you should opt for roof replacements. 

Or, if you live in a mild climate, even re-roofing can work for you.
