Whenever you decide to replace roof shingles, it will be a hefty investment. You want to ensure that you have a good understanding of the roof replacement process so you can make an informed decision for your house. This article will help you understand the 2 key methods that are used to install roofs.
Roof Overlay:
If you are seeking a method to install roof shingles over the existing ones, roof overlay is the approach you should consider. This is a more non-invasive method where a new layer of roof shingles is installed over the old, existing ones.
Advantages of Roof Overlay:
Cost-effective: Roof overlay is an excellent choice for the ones on a tight budget who are seeking to replace roof shingles. Because you do not need to remove the old roof, this method saves you money on labor and materials. You won’t even have to spend on disposing of the old roof.
Time-saving: The process of roof overlay is quicker and more convenient. It does not need the hassle of removing the old roof shingle, saving time. Shingle roof installers use this method for its efficiency and ease.
Minimal disruption: This method is quick and causes minimal disruption to your daily life since you won’t have to deal with the debris from the old roof shingles.
Limitations of Roof Overlay:
Hidden structural issues: This method of installing roof shingles over existing ones ignores any potential issues that may be present within the current roof structure. For instance, if there is rot or damage within the current roof deck, roof overlay will not address or fix the problem. In such cases, you may only discover the problem when it worsens overtime and will need a more extensive roof replacement process. So roof overlay may not be the best option if your roof has some underlying structural concerns.
Shortened lifespan:
In the roof overlay method, you are installing new roof shingles on top of the existing shingles which adds a lot of weight on your home structure. This may compromise the structural integrity of your house and cause the foundations to weaken.
Uneven Application:
When new roof shingles are installed over existing ones, there can be issues with deteriorating shingles underneath that result in an uneven application of the overlay. This can also occur if the roof deck has experienced wear and tear in the past.
Limited material options:
The roof replacement process in this method requires a specific set of materials to keep the structure lightweight. This may limit your choice of materials and aesthetic preferences.
Roof Tear Off:
As the name suggest, in this method, the existing roof is completely taken off and replaced with new roof shingles with all new materials.
Advantages of Roof Tear Off:
Uncover underlying issues: In this method, roof installers can inspect the roof deck and detect any potential issues that may be present beneath the structure. Since the old roof is stripped off, it makes it possible to fix these issues before new roof shingles are installed. Issues like leakages, mold, or other damages can be dealt with before they get any worse.
Extended Lifespan:
Tear-off projects are excellent long-term investments because they begin with a fresh slate, using completely new materials. This approach provides you with a brand-new look and structure that can last for decades if installed properly.
Variety of Material Options:
This method of roof replacement gives you a variety of material options to choose from as you will not be limited to lightweight materials. This will allow you to cater to your aesthetic preferences more easily.
Lower Maintenance:
In the roof tear-off method the maintenance costs will be lower. All the components of your roof deck will be removed and replaced with new ones, which will give you durability.
Limitations of Roof Tear Off:
Higher Costs:
Roof tear off incurs the costs of stripping and disposing the old roof shingles and replacing them with new materials. This is a more labor-intensive method which will cost you more than its alternative.
Longer Project Duration:
This method is also likely to consume more of your time compared to the roof overlay method. It involves stripping off the existing roof and installing new roof shingles. This takes a longer duration to complete, resulting in a more extended period of disruption in your home.
Which Method Should You Choose?
Now that you are well aware of the pros and cons of both methods, let us look at the factors that will influence your decisions when choosing a roof installation process.
Roof Condition Assessment:
The choice of the appropriate roof replacement method depends on the condition of your existing roof. If you have not replaced your roof shingles in a decade or more, the roof tear-off method would be more suitable for you. But, if your roof is relatively new and undamaged, and you want to update its appearance, the roof overlay method would be a good option for you.
Budget Considerations:
Budget constraints are one of the primary factors that influence decisions of roof replacements. It’s important to keep in mind that roof overlay is more budget-friendly in the short term. Overlay is generally a more affordable method initially, but it may incur maintenance costs down the road. In contrast, roof tear-off is likely to provide you with a longer-lasting solution that requires less maintenance. Roof tear-off also provides long-term value due to its increased durability.
Aesthetic Preferences:
Roof tear off method is good for you if you have a specific aesthetic in mind that you want to achieve. This method allows you a wide variety of roof deck materials to choose from. Roof overlays may limit your choices to lightweight materials only, which may not give you the desired aesthetic.
