One of the most significant investments when it comes to maintaining a house is your roof. Unfortunately, when your roof shows any signs of damage, sometimes it’s hard to tell whether you need a reroof or replacement?
In today’s article, you will know the difference between Reroofing VS Roof Replacement to help you opt for the best option for your situation.
What is the Difference Between Roof Replacement and Reroofing?
Time will come that your roof needs replacement or perhaps improvement. But, of course, you can’t just get to a decision if you don’t know the current state of your roofing.
So, here’s what to know about reroofing vs roof replacement.
What Does Reroof Mean?
Reroofing is the quickest process of layering a set of other shingles over a set of your current shingles. So it’s not a surprise that restoring your old roof is faster and affordable than replacing your roof.
It’s probably a cheap way to restore your roof’s proper appearance. When a new shingle is placed over your damaged shingles, it helps prevent leaks from getting inside your home.
The reroofing process is done to improve your roof’s appearance and offer a layer always to prevent leaks. However, if you currently have significant water damage, reroofing is not an option.
The same is true with extreme water leaking damage, missing shingles, or wet shingles. If this is the case, you should know that reroofing does not last long as a roof replacement.
Reroofing can only be done once, provided that you still have one layer of shingles on your roof.
So, if you already have two layers of reroofing, then know that your roof is not a candidate for reroofing. Installing the third layer is prohibited by building codes; thus, you already need an entire roof replacement.
Is It OK to Put a New Roof Over an Old One?
In most cases; Yes, you can put a new roof over the old ones. Provided that your old roofing is in good condition.
However, if it’s about time to replace the shingle with new ones, putting a new roof layer of shingles over the old one would be appropriate.
Benefits of Reroofing
Reroofing can sometimes be beneficial for homeowners whose roof is nearing the end of its life span. However, here are some of the cons when you opt for the reroofing process.
- Stronger support
Since you’re adding a second layer, it’s also adding strength to your roof. The extra material would strengthen the roof and make it harder for wet elements to get into your house.
Unlike roof replacement, reroofing does not require the same labor, materials, and time – making it a cheaper option. For example, if you only have slight damage to your roof, such as single shingle layering, you don’t have to buy new materials to replace the entire roof.
- Fastest way
Reroofing does not require replacing your entire roof. Therefore, it’s the fastest way to restore your roof. Furthermore, it’s going to be quick and easy to do.
- Cosmetic facelift
Many shingle roofs would get discolored or dirty looking over the years. With reroofing, you can get a total roof makeover without actually replacing the roof.
Drawbacks of Reroofing
Reroofing can sometimes do more damage than good. It’s good if you would take into consideration the concerns of reroofing. Here are some drawbacks you need to be aware of.
- Not recommended for metal proofing
If you have metal roofing, reroofing may not be the best choice.
- Temporary solution to the problem
Unlike roof replacement, reroofing can’t last longer than replacing the roof. So, it’s just a temporary solution to the problem. It only means that it’s not as full-proof as entirely replacing your roof.
- Prohibited in adding the third layer
If you already put two shingles on your roof, then adding a third layer is prohibited.
- Hard to figure out damages
Reroofing only works to cover current shingles. It would be hard to know if there are existing damages underneath, such as sagging or rotting. It only goes to show that a new layer of shingles will not fix major issues.
Understanding the Concept of Reroofing VS Roof Replacement
Roof replacement happens when you tear off everything on the roof down to the deck. This happens when your deck is severely damaged and needs repair to prevent worsening the situation.
When the roof is replaced, the old shingles are stripped from the roof, exposing the deck.
An underlayment or felt paper is applied to the deck if it’s damaged to protect water and other elements from getting inside your home.
Full replacement is done no matter how many layers of shingles are on the roof, and the installed replacement could last 20 years or more.
If the issues with your roof deck are intolerable, then a roof replacement is appropriate. Roofing companies had to remove all the deep-rooted shingles from your roof and later install another underlayment.
Unfortunately, the holes underneath will permit water to drip into the walls, which would cause damage to drywall and flooring.
If this is the case, the replacement for this damage is a bit expensive. But in the long run, you will realize that this costly project will save you money.
The bottom line is that roof replacement will keep the roof deck from elements, and contractors will completely recover the roof deck with new shingles.
Of course, the replacement should last for at least twenty years, or even longer. It would be worth the money you saved than getting a reroofing. It’s even safer and long-lasting.
Benefits of Roof Replacement
Check out some of the benefits you could get when deciding to have a full replacement of the roof.
Roof replacement lasts longer than reroofing alone. That said, you will never have to worry about fixing it any time soon.
- Can be done regardless of the shingle layers
Roof replacement can be done no matter how many layers of shingles are on the roof. Since you’re going to remove old layers of shingles, you would be able to fix the damages underneath easily.
- Sturdier and safer roofing
Unlike reroofing, which covers up any issues with your roof deck like sagging and rotting that may become worse later, with a fully revamped roof, it addresses all issues to get that safe and sturdy roof.
- It will save you money
Since roof replacement tackles the problem at its very core, then it could save you more in the long run. It enables you to determine early signs of rotting and sagging because of water damage. Second, it prevents worsening the situation, thereby preventing you from shelling out money for an expensive repair.
Drawbacks of Roof Replacement
Despite the benefits of getting a roof replacement, there are some concern/s that need to be considered.
Since you will replace your roof entirely, it means you have to spend more on labor costs, time, and materials.
Therefore, you need to prepare a significant budget if you opt for this option. However, on the brighter side, this is going to be worth it.
Expected Costs for Reroofing vs Roof Replacement
The costs of these methods vary drastically because there are different factors to consider, like the materials, size, current location, and the overall labor.
There are also other tools you need and other factors to include, such as the level of your house and where you’re located. In this section, you will get ideas on expected costs for both processes.
The costs for reroofing may vary based on labor, job size, materials, and location. In addition, if there is a need for special equipment like roof jacks, it may also affect the cost. Also, the slope or story of your house is a big factor that will affect reroofing costs.
- The slope of the house
Say, for instance, if your house comes with a vertical slope and two stories, it will need more time and labor for the construction team or contractors to work with your roof. Unlike a single-story home with a lower slope, a two-stories home would require them to get up and down every time. That said, the higher the slope, then the higher the costs, and vice-versa.
Another aspect that could affect the cost of the reroofing project is the materials. For example, when you go for asphalt shingles, then the cost would be low. However, if you opted for metals for materials, it often requires other services that could also add to the cost.
You should also know that metal roofs can save you money in the long run compared to asphalt roofs. Metal roofing is more cost-effective and is proven to last even through rough weather conditions.
On the other hand, asphalt shingles tend to be weak and could get damaged by strong winds and falling debris. This means that asphalt shingles need to be replaced more often.
Roof Replacement Costs
Replacing the roof requires extensive labor. If you’re planning to have roof replacement in the future, here are the things you need to consider.
- Replacement of the entire roof
Since roof replacement will need you to remove the old and damaged shingles, you must allot more budget in preparing the surface for new installation. This is costlier than reroofing, and the costs depend on your location.
- Size of the roof
Among the biggest cost factors for full replacement of the roof are the size and slope characteristics. Contractors often charge you with the size or per roofing square. However, you have to be aware that the larger the roof, the costlier it gets to replace it.
- Steep slopes
Steep slopes could also increase the cost of the replacement, as it needs special requirements. For example, you need additional equipment, and the workers would need safety gear and harnesses to walk on the floor.
- Complex designs
Of course, if you want to make your roof look beautiful and modern, it could also increase the cost. Perhaps you do need an architect to design your new roof, and it would also require time for the laborers to finish it.
- Damages are big
If your roof has severe water damage, this may also affect the cost because it needs repairing before having the new roof installed.
- Accessibility to the roof
Another factor that would impact the cost of roof replacement is the convenience when going to the roof. If it’s challenging for a truck to get to your house, materials would have to be carried from the truck to your location. This will require more time and labor, hence increasing the cost.
- Additional features of your house
If you have other features like a chimney or skylights, the laborers must work around them. Perhaps they need to remove it for a while and return it once done. This would also cause the cost to increase as the workers may also add a fee to haul or dispose of old debris and materials. And if these features also need to be repaired, you will add for the labor as well.
Can a Roof be Repaired Instead of Replaced?
Deciding what’s best for your roof requires thorough assessment by professionals or roofers. However, not all home improvement decisions are dry and cut. For instance, it’s possible sometimes and even acceptable to repair your roof rather than replace it.
The decision varies on several factors and the kind of damage it has. That’s why you need to consult a professional first before jumping into a decision for your roof improvement.
If you’ve come to a point in weighing your options between reroofing and roof replacement, then you have to consider factors we discussed above that would contribute to your decisions. Better yet, we here at RoofCalc suggest you should hire a professional so you will not waste your money and time on this decision.
