For homeowners, choosing between a reroof vs. new roof is a major decision. One of the most crucial components of your house is its roof, which both protects it from the weather and improves its overall appeal. The state of your roof, your financial situation, and your long-term goals all play a role in selecting the best course of action.
To help you choose the best option for your home, this blog post will explain the differences between installing a new roof and reroofing.
What Is Reroofing?
The process of replacing an old roof with a new one is called reroofing. This is typically done by either overlaying the old roof with a fresh layer of shingles.
This approach is frequently used to update the home’s visual appeal, increase energy efficiency, or strengthen the structure of the roof. If you are considering a roof replacement, reroofing can be the more affordable option, particularly if the underlying structure is still intact.
However, before reroofing, it is crucial to evaluate the current roof’s condition and make sure it complies with local building requirements.
When Is Reroofing Appropriate?
- End of Shingle Lifespan: If your shingles are worn down but the roofing structure is still solid, reroofing can extend its life.
- Minor Leaks: Reroofing can seal small leaks by adding a new layer of shingles over the old ones.
- Single Layer of Shingles: Reroofing works only if there’s one layer of shingles. More layers usually require a full replacement.
- Partial Roof Issues: If only certain areas are damaged, reroofing those sections can be a cost-effective fix.
What Are the Pros and Cons of Reroofing?
| PROS | CONS |
| Affordable Option: Reroofing is usually cheaper than a full replacement, especially if the roof is in good condition. | Limited Longevity: Reroofing only adds 10-20 years to the roof, while a full replacement lasts longer. |
| Quick Installation: It takes less time than a full replacement, allowing homeowners to resume normal activities sooner. | Unaddressed Issues: Hidden problems like leaks may get overlooked and worsen over time. |
| Minimal Disruption: Reroofing causes less mess and noise compared to a complete tear-off. | Higher Long-Term Costs: Maintenance or repairs could add up, making it more expensive in the long run. |
| Quick Process: The project usually wraps up faster, minimizing interruptions to daily life. | Added Weight: The new layer of shingles can increase the roof’s weight, requiring extra support. |
What Is a New Roof?
On the other hand, getting a new roof means fully removing the existing roofing materials (and potentially the entire structure) and replacing it all with new material. This process is essential when the roof has suffered significant damage, or when there are multiple layers of shingles to be removed. By tackling both the surface and underlying parts of the roof, this method ensures a solid foundation, ultimately boosting the new roof’s durability and extending its lifespan.
When Is a New Roof Necessary?
- Age of the Roof: Roofs over 20 years old, especially those with asphalt shingles (which last 15 to 25 years), may need roof replacements.
- Visible Damage: Shingles that are lifted, cracked, or curled indicate deterioration, often requiring a full roof replacement.
- Frequent Leaks: Ongoing leaks in several areas suggest the roof has reached its limit or wasn’t installed correctly, requiring replacement.
- Sagging or Moss Growth: Sagging or moss can signal trapped moisture, which could cause structural damage and indicate the roof should be replaced.
- Missing Shingles: Missing shingles leave your home vulnerable to water damage, so an inspection is needed to check if a roof replacement is necessary.
- Daylight in the Attic: Seeing daylight through the roof deck in the attic may indicate serious damage and usually means a new roof is needed.
- Professional Recommendation: If a licensed contractor recommends a new roof, it’s wise to follow their advice to prevent more damage and higher costs in the future.
What Are the Pros and Cons of Getting a New Roof?
| PROS | CONS |
| Improved Look: A new roof makes your home look better, which can increase its value and appeal to buyers. | High Initial Cost: New roofs can be expensive, depending on the materials and installation complexity. |
| Better Energy Efficiency: Modern roofs help keep your home cooler in summer and warmer in winter, lowering your energy bills. | Disruptive Installation: Replacing a roof can be noisy and messy, making daily life harder for a while. |
| Less Upkeep: New roofs need less maintenance, saving you time and money on roof repairs. | Weather Delays: Bad weather can delay the installation, which might leave your home exposed for longer. |
| Better Protection: A new roof provides more protection from bad weather, reducing the risk of leaks and water damage. | |
| Longer Lifespan: A new roof can last much longer than an old one, giving you peace of mind for years. |
Key Differences Between Reroofing and New Roof Installation
Now that you know what the difference between a new roof vs. a reroof, you should know the differences between each so you can choose the best option for your own home:
1. Cost
When choosing between a reroof vs. a new roof, cost is a key factor. Reroofing usually costs around $5,000 and $10,000, depending on materials and labor, while a full roof replacement starts around $20,000 and can increase with complex installations and premium materials. While reroofing may seem cheaper initially, a new roof can provide better long-term durability and energy efficiency.
2. Time to Complete
Reroofing typically takes less time to complete. Since it involves adding a new layer of shingles over the old ones, the project can be done quickly, and often in just a few days. On the other hand, a new roof installation involves more time for teardown, possible structural repairs, and the new installation process, which can take longer.
3. Lifespan
By adding a new layer of material, reroofing extends the life of your roof for another 15 to 20 years. However, it doesn’t address underlying problems that could affect its longevity. A new roof, built with fresh materials, offers a longer lifespan of 25 to 30 years or more, as it allows for structural issues to be repaired.
4. Damage Repair Capability
Repairs with reroofing are limited to what’s visible on the surface. Hidden problems, such as leaks or rot, could go undetected. A new roof offers a chance for comprehensive repairs, ensuring the underlying structure is in good shape before the new materials are installed.
5. Suitability
Reroofing is a good option for homes with minimal damage and a single layer of shingles in good condition. It’s an ideal short-term fix. However, when the roof has multiple layers or significant damage, a new roof is a better long-term solution.
6. Aesthetic Appeal
While reroofing can refresh the appearance of your roof quickly, it may not provide the clean, polished look of a brand-new roof. Installing a new roof allows for a complete upgrade in design and materials, boosting your home’s curb appeal.
7. Warranty Considerations
With reroofing, warranties on the new shingles installed over the old ones might be limited. Many manufacturers do not like their products used for reroofing and will void warranties if damage occurs due to reroofing. A new roof typically comes with a full warranty, covering both materials and workmanship, providing more peace of mind and protection.
8. Energy Efficiency
Using existing materials in reroofing may not improve the energy efficiency of your home. A new roof, however, offers the chance to choose energy-efficient materials like reflective shingles or better insulation, helping to reduce energy costs.
9. Long-Term Maintenance Needs
Reroofing systems may need more maintenance over time due to hidden problems not being addressed. These issues could get worse if they were not checked regularly, which means they require more frequent maintenance. On the other hand, new roofs usually need less maintenance since they come with warranties and are built to last longer, offering better protection against the weather.
10. Insurance Considerations
A new roof often results in reduced premiums due to its improved structure and compliance with modern building codes. Typically, reroofing will not receive the same insurance benefits.
11. Resale Value
Investing in a new roof can significantly boost your home’s resale value. Potential buyers will appreciate the long-lasting, durable roof. While reroofing increases value, a full roof replacement offers more significant returns.
Final Verdict: Reroof or New Roof Installation?
Reroofing is a quicker, more affordable option for minor roof repairs, but it doesn’t address deeper issues. A new roof costs more and takes longer, but it fixes major damage and offers better durability. Ultimately, the decision depends on your needs and budget.
