Asphalt Shingle Restoration: How It Works and When to Use It
Understanding how asphalt shingle restoration works can help you decide if it’s a good option for your roof. The process is simple, far less disruptive than a full roof replacement, and offers a practical way to extend your roof’s life.
The Restoration Process
Restoration focuses on replenishing the oils and resins in shingles, which are essential for maintaining their flexibility and waterproofing. Over time, exposure to UV rays, extreme temperatures, and weather strips these oils away, leaving shingles brittle and prone to damage.
"Roof rejuvenation restores the asphalt shingles' flexibility, malleability, and waterproofing properties." – Pristine Clean
The process involves three key steps:
- Inspection and Preparation: Professionals assess your roof to determine if it’s a good candidate for restoration. Typically, roofs aged 5–15 years with signs of aging but no major structural damage, severe curling, or leaks qualify. Before treatment, the roof is cleaned thoroughly to remove dirt, moss, and algae, ensuring the solution absorbs evenly. Minor repairs, like replacing damaged shingles, are completed at this stage.
-
Application of the Rejuvenating Solution: A specialized bio-based treatment, often made with soy methyl esters or modified triglycerides, is sprayed evenly over the shingles using a low-pressure system. Some formulations include synthetic polymers for added waterproofing and UV protection. Technologies like GreenSoy are designed to penetrate aging shingles, improving their resistance to weather and wear.
"By spraying our treatment onto asphalt shingles, we can help restore their flexibility and prevent them from cracking." – Roof Maxx
- Absorption and Activation: The solution begins to penetrate the shingle surface within 30–60 minutes and cures over the next few days. This process restores flexibility, enhances water resistance, and strengthens granule adhesion by reacting with the oxidized asphalt in the shingles.
The entire process typically takes 2–3 hours for most homes and causes minimal disruption. Restoration works best during warm, dry weather when temperatures are above 50°F, and no rain is expected, ensuring the treatment cures effectively.
Benefits of Choosing Restoration
Restoration offers several advantages, making it an appealing choice for many homeowners. It’s significantly more affordable than a full roof replacement and can add years to your roof’s life.
Research has shown that treated shingles regain flexibility, improve granule adhesion, and resist weather damage better. Regular treatments - usually recommended every five years - can keep your roof in top shape for even longer. Treated shingles also show better resistance to wind and hail, while improved granule adhesion helps maintain their protective layer.
Another big plus is the minimal disruption. Unlike a full replacement, which can last several days and create noise and debris, restoration is quick and clean, allowing you to go about your day with little interference.
Best Candidates for Restoration
Not every roof is a good fit for restoration, so choosing the right candidate is critical. The process works best for asphalt shingle roofs that are 5–15 years old and show moderate wear, such as slight granule loss or early signs of brittleness, but still have a solid structure. Roofs with major leaks, extensive rot, or severe storm damage are not suitable, as restoration is designed to rejuvenate shingles, not fix structural issues.
This method is specifically for asphalt shingles and isn’t recommended for other materials like wood, tile, or metal roofs, or for flat or low-slope roofs. Timing also matters - if your roof still has several years left but is starting to show signs of aging, restoration can be a smart preventive measure. However, if the roof is already in poor condition, a full replacement may be the better option.
New Roof Installation: Process and When It's Required
When repairs won’t cut it, replacing the entire roof is the way to address severe damage and structural issues. This ensures your home gets the protection it needs for the long haul.
The Roof Replacement Process
Replacing a roof is no small task - it’s a significant project that can take a few days, depending on the size and complexity of your home. Unlike quick restoration jobs, this process involves stripping the roof down to its base and rebuilding it step by step.
It all starts with a complete tear-off. Contractors remove everything - shingles, underlayment, and flashing - exposing the roof deck. Once the deck is visible, it’s inspected thoroughly, and any damaged sections are replaced with new sheathing.
After that, a fresh layer of underlayment is applied. This moisture barrier, often synthetic or felt paper, is essential for protecting the roof. In areas prone to leaks - like eaves, valleys, and spots around chimneys or vents - an ice and water shield is added for extra protection. New flashing is then installed to seal off edges and prevent water from sneaking in.
Finally, the new shingles go on, starting from the bottom and working upward. Roofers ensure proper overlap and secure fastening, adding ridge caps, hip shingles, and updated ventilation systems to complete the job.
Weather can sometimes throw a wrench in the timeline. Rain, snow, or high winds can delay work, but contractors often use tarps to shield the exposed roof if conditions take a turn.
Once the project wraps up, the benefits of a brand-new roof become obvious.
Benefits of a New Roof
With all-new materials in place, you eliminate the risks that come with aging components or hidden damage.
A new roof also boosts your home’s curb appeal. The uniform look of fresh shingles, with their consistent color and texture, can make a huge difference. Plus, modern roofing materials are built to perform better - they offer stronger wind resistance, UV protection, and even algae-resistant coatings.
Homeowners can also take comfort in warranties. Many manufacturers provide strong product warranties, and reputable contractors often back their work with labor guarantees. These assurances add peace of mind about the roof’s durability and performance.
Energy efficiency is another perk. Upgraded underlayments and proper ventilation can lead to lower cooling costs. Some high-end shingles even feature reflective granules, which help reduce heat buildup and may qualify for tax credits.
In short, a new roof means fewer worries about repairs and a more reliable structure over your head.
When Replacement is Your Only Option
Sometimes, replacing the roof isn’t just a choice - it’s a necessity. Certain conditions make repairs impractical:
- Severe structural issues like rot, sagging, or widespread water damage
- Large areas of missing or heavily damaged shingles
- Persistent leaks or multiple sources of water intrusion
- A roof nearing the end of its expected lifespan
- Building codes requiring updates for ventilation, ice dam protection, or wind resistance
If repair costs start creeping close to the price of a full replacement - or if your roof has several major problems - investing in a replacement is often the smartest move for the long term.
Cost Breakdown: Restoration vs New Roof Installation
When it comes to roofing, cost is often a deciding factor. While the exact expenses depend on variables like roof size, material quality, location, and condition, it’s helpful to understand the general differences between restoration and a full replacement. Below, we break down the costs for each option and provide a comparison to guide your decision.
Asphalt Shingle Restoration Costs
Restoring a roof is typically much more budget-friendly than replacing it entirely. The total cost of restoration depends on several factors, including:
- The size of your roof
- The current condition of the shingles
- The type of restoration treatment used
- Local labor rates
One of the biggest advantages of restoration is that it reduces both labor and disposal costs. Instead of tearing off and replacing the entire roof, restoration focuses on refreshing and extending the life of the existing materials.
New Roof Installation Costs
On the other hand, installing a new roof involves higher expenses due to several reasons:
- Premium material costs, such as upgraded shingles, underlayment, and flashing
- Extended labor hours for the installation process
- Fees for removing and disposing of the old roof
- Possible costs for addressing structural repairs
These additional requirements make the cost per square foot for a new roof significantly higher than that of a restoration.
Side-by-Side Cost Comparison
Here’s a quick comparison of the key cost factors for restoration versus a new roof installation:
| Cost Factor | Restoration | New Roof Installation |
|---|---|---|
| Total Project Cost | Lower | Higher |
| Cost Per Square Foot | Lower | Higher |
| Project Timeline | Quick turnaround | Longer process, several days |
| Disposal Fees | Usually not needed | Additional removal fees |
| Potential Structural Repairs | Rarely required | More likely needed |
| Warranty Coverage | Transferable property warranty | Material and labor warranties |
Restoration is an economical option that can extend the life of your roof while requiring less time and fewer additional expenses. However, whether to restore or replace ultimately depends on the current condition of your roof, your long-term goals, and the performance you expect from your investment.

Durability and Long-Term Performance Comparison
After breaking down costs and processes, it's important to dive into how each option - restoration or a new roof installation - holds up over time. Your choice impacts your home's protection and long-term expenses.
How Long Restoration Lasts
Restoration treatments can extend a roof's life by up to five years per application. With repeated treatments, you might delay a full replacement by 10–15 years. One of the biggest perks? Restoration can be done multiple times. If the first treatment works well, additional applications may keep your roof functional for years.
That said, restoration isn't a fix-all solution. It works best on roofs that are structurally sound. These treatments can rejuvenate shingles, restoring flexibility and extending their life, but they can’t fix major structural issues or significant material damage. To get the most out of restoration, it's crucial to act before serious deterioration sets in. Now, let’s look at the durability of a brand-new roof.
How Long New Roofs Last
A new roof offers a more predictable lifespan, as defined by the manufacturer. For asphalt shingles, the expected longevity varies by type:
- 3-tab shingles: 15–20 years
- Architectural shingles: 22–30 years
- Premium shingles: 30+ years
However, warranties typically cover defects, not the entire lifespan. Factors like material quality, installation quality, climate, and sun exposure can influence how long a new roof actually lasts. For example, roof slopes facing south or west often wear out faster due to higher sun exposure.
Performance Comparison Table
| Performance Factor | Restoration | New Roof Installation |
|---|---|---|
| Expected Lifespan Extension | Up to 5 years per treatment | 15–50 years total |
| Retreatment Options | Can be repeated multiple times | Not applicable |
| Maintenance Requirements | Annual inspections and proper ventilation required | Annual inspections and proper ventilation required |
| Weather Resistance | Improved performance | Maximum protection |
| Structural Limitations | Does not address underlying damage | Addresses all structural issues |
| Performance Predictability | Varies based on existing condition | Consistent with manufacturer specifications |
Regular maintenance, like annual inspections and proper ventilation, plays a big role in maximizing the lifespan of both options. Deciding between restoration and replacement depends on your roof’s current condition and age. A professional evaluation can help you determine whether restoration is a smart choice for extending your roof’s life or if a full replacement is the better long-term investment.
Which Option is Better for the Environment
When deciding between restoring your roof or installing a new one, considering the environmental impact can be a meaningful factor. Alongside cost and durability, understanding how each option affects the planet might help you make a choice that aligns with your values.
How Restoration Helps the Environment
Restoration is often considered the greener choice because it reuses existing roofing materials, cutting down on the waste that ends up in landfills. Instead of tearing off and discarding the old roof, restoration breathes new life into it, reducing the need for freshly manufactured materials.
Companies like Scharf Fresh Roof take it a step further by using their patented GreenSoy Technology and committing to plant a tree for every treated roof. This adds a layer of environmental responsibility by supporting reforestation efforts.
The Environmental Cost of New Roofs
Installing a new roof, on the other hand, involves completely removing the old one, creating a significant amount of waste. The process requires manufacturing entirely new materials, which consumes more energy and raw resources. This higher demand for production often translates to a larger carbon footprint.
Environmental Impact Summary
| Environmental Factor | Restoration | New Roof Installation |
|---|---|---|
| Landfill Waste | Reduced by reusing materials | Increased due to removal and disposal |
| Manufacturing Impact | Minimal, as fewer new materials are needed | Higher, with all components newly produced |
| Transportation Emissions | Fewer trips for on-site treatment | More trips for removal and delivery |
| Resource Consumption | Lower, by reusing existing components | Higher, due to extraction and production |
| Positive Environmental Actions | Includes tree planting initiatives | No associated sustainability efforts |
Restoration tends to have a smaller environmental footprint, conserving resources and generating less waste. That said, the condition of your roof plays a big role in the decision. If your roof is severely damaged, replacing it might be the safer and more practical choice. Balancing these environmental considerations with cost and durability can help you make the best decision for your home and the planet.
How to Choose Between Restoration and Replacement
Deciding whether to restore or replace your roof depends on several factors: the roof's current condition, your budget, timeline, and long-term goals. Below, you'll find a detailed breakdown of when each option makes sense, along with a helpful decision guide table.
When to Choose Restoration
Restoration works best for roofs that are structurally sound but have minor issues like small cracks or superficial weather damage. It’s a practical solution for extending your roof's life without a full replacement.
"If the building owner aims to extend the roof's lifespan by another 10-20 years with less than 25% repair needed, roof restoration is an excellent choice." - Holcim Building Envelope
This option is well-suited for those working with tight budgets, looking for quicker fixes, or prioritizing environmentally friendly solutions. However, if the roof's condition is beyond these limits, replacement becomes the safer and more reliable option.
When to Choose Replacement
A roof replacement is necessary when severe damage or advanced aging compromises the roof's integrity. Problems like chronic leaks, sagging areas, or significant storm damage often signal that restoration won’t be enough. Additionally, roofs with two or more existing layers typically require a full replacement.
"When other solutions cannot meet performance or longevity requirements, or if the building has already reached the limit of reroofing and restoration options (with two or more roofs/coating layers), replacing the roof is the final option." - Holcim Building Envelope
Replacement is a smart choice if you plan to stay in your home for 20 years or more and want a roof that can handle extreme weather over the long haul. While the upfront cost is higher, the extended lifespan and durability make it a worthwhile investment.
Decision Guide Table
| Factor | Choose Restoration | Choose Replacement |
|---|---|---|
| Roof Condition & Age | Structurally sound, less than 25% repair needed | Extensive damage, structural problems, widespread issues |
| Existing Layers | Single layer or first restoration | Two or more existing roof assemblies |
| Budget | Cost-effective for limited budgets | Larger budget for long-term investment |
| Timeline | Quick solution with minimal disruption | Longer installation process acceptable |
| Future Plans | Short-term use or selling within 5–10 years | Staying long-term; need for maximum durability |
| Environmental Priority | High – minimize waste and support sustainability | Moderate – may involve a higher environmental impact |
| Expected Lifespan | Additional 10–20 years | 25–30+ years |
Before making a decision, take the time to thoroughly inspect your roof. Look for visible issues like punctures, pooling water, weak spots, or improperly sealed seams - especially around rooftop equipment like HVAC systems. Pay attention to any signs of water leakage and areas prone to wind or hail damage.
For the most accurate assessment, consult a professional roofing contractor. They can evaluate your roof’s condition, explain your options in detail, and ensure any decisions align with local building codes and long-term needs.
Final Thoughts on Restoration vs Replacement
When deciding between asphalt shingle restoration and a full roof replacement, it’s essential to weigh factors like cost, durability, and environmental considerations. As mentioned earlier, restoration is ideal for addressing minor damage, while replacement tackles more severe issues. These differences highlight the importance of expert evaluation to make the right decision.
Key Differences Between Restoration and Replacement
Restoration focuses on repairing and renewing the existing roof, making it a more budget-friendly option for minor damage. It also reduces waste by reusing materials. On the other hand, replacement involves completely removing and replacing all roofing materials, offering greater durability but with a higher upfront cost and more waste generation.
Restoration is generally quicker and less disruptive to your daily life. In contrast, a replacement takes more time and can cause greater interruptions to your routine.
The Importance of Professional Assessment
Given these distinctions, a professional inspection is critical. Experts can uncover hidden damage and determine whether restoration will suffice or if replacement is necessary. They also evaluate the structural integrity of your roof and ensure no underlying issues are missed.
Roofing professionals are well-versed in local building codes, permit requirements, and weather-related factors that might affect your roof.

FAQs
How do I know if my asphalt shingle roof needs restoration or a full replacement?
Determining whether your roof needs a restoration or a full replacement comes down to its condition and age. If your roof is dealing with minor to moderate issues - like worn shingles, small leaks, or general surface wear - restoration could be a budget-friendly option. Techniques such as cleaning, sealing, or patching can often give your roof a longer life.
On the other hand, if the damage is severe, there are structural concerns, or your roof is nearing the end of its typical lifespan (around 20–25 years for asphalt shingles), a complete replacement might be the smarter choice. To make the right call, it’s best to bring in a professional roofer who can assess the roof's age, condition, and the extent of any damage.
What are the environmental advantages of restoring asphalt shingles instead of replacing the roof?
Restoring asphalt shingles offers a smarter, environmentally conscious alternative to a full roof replacement. By extending the life of your existing roof, it keeps massive amounts of old shingles from ending up in landfills each year. This choice also helps conserve raw materials, reducing the demand for new resources.
On top of that, restoration cuts down on the carbon emissions tied to producing, transporting, and disposing of new roofing materials. So, when you opt for restoration, you're not only saving money but also making a choice that supports a healthier planet.
What’s the long-term cost difference between restoring asphalt shingles and replacing the entire roof?
The cost of restoring asphalt shingles versus replacing the entire roof largely hinges on the roof's condition and the level of damage. Restoration often presents a more budget-friendly option upfront, especially if the roof's structure remains intact and only the shingles require attention. This approach can extend the lifespan of your roof without the hefty expense of a complete replacement.
On the other hand, if the roof has significant damage or is approaching the end of its lifespan, a full replacement could be the smarter financial move in the long term. While it demands a larger initial outlay, it provides better durability and reduces maintenance costs over time. Evaluating your roof’s current state thoroughly is crucial to making the most cost-effective decision.
