Roofing Exxplained - Episode 15: Asphalt Shingle Roof Rejuvenation

How Asphalt Shingles Age Over Time

Asphalt shingles don’t stay the same forever - they start aging the moment they’re installed. Knowing how this process unfolds can help you determine when it’s time to take action and prolong the life of your roof.

When new, asphalt shingles rely on petroleum-based oils to stay flexible and waterproof. These oils allow the shingles to adjust to temperature changes without cracking. Over time, though, these essential oils begin to evaporate. This gradual loss makes the asphalt harder and less flexible, increasing the risk of cracking. The process tends to speed up after about 10 years, as much of the original oil content has already diminished. At this stage, shingles become more vulnerable to wear and tear caused by weather.

Weather and UV Damage Effects

Weather plays a big role in how quickly shingles age. UV rays from the sun can break down the bonds in asphalt, causing shingles to become brittle. During hot summers, roof temperatures can soar to 150°F, softening the material. In winter, freezing temperatures cause the shingles to contract. This constant cycle of expansion and contraction weakens the material over time.

Wind and hail also take a toll. Shingles that have lost flexibility due to aging are less able to withstand impacts. Hail that might only dent a newer roof can cause cracking and granule loss on older shingles. Moisture is another enemy. Rain can wash away loose granules, while water that seeps into small cracks accelerates underlying damage. Once water gets beneath the shingles, it can lead to even bigger problems, such as material deterioration beneath the surface.

Warning Signs of Roof Deterioration

There are several telltale signs that your shingles are aging and losing their effectiveness:

  • Granule loss: This is often the first thing homeowners notice. You might see colored granules collecting in your gutters or notice bare spots on your shingles where the protective coating has worn off.
  • Curling, cupping, and cracking: As shingles lose moisture and flexibility, their edges may lift (curl) or cup inward, creating openings for water to seep in. Cracks can form as the asphalt becomes too brittle to handle temperature changes, and these cracks can grow larger during freeze-thaw cycles.
  • Color fading: UV exposure can cause the pigments in the granules to fade. While this might seem like a cosmetic issue, it often signals that the shingles’ protective properties are breaking down.
  • Bald spots: When granules are completely worn away, the asphalt layer becomes exposed. These areas are highly vulnerable to further damage and water infiltration.

For most asphalt shingle roofs, these signs become noticeable between 15 and 20 years, though roofs in harsher climates may show wear sooner. By keeping an eye on these aging patterns, you can time roof maintenance or rejuvenation efforts to extend your roof’s life before significant damage occurs. Spotting these issues early means you can address them before they lead to costly repairs or replacement.

How Roof Rejuvenation Works

Roof rejuvenation tackles the aging process of asphalt shingles by restoring their flexibility, waterproofing, and strength. Over time, asphalt shingles lose their petroleum-based oils, becoming brittle and less effective. Rejuvenation works by chemically replenishing these lost oils, bringing back the flexibility and waterproofing properties that are critical for a durable roof.

The Roof Rejuvenation Process

The rejuvenation process is a carefully planned procedure designed to deliver the best possible results. On average, the entire process takes about 2–3 hours.

It begins with a thorough roof inspection. Technicians check for any issues and carry out minor repairs to ensure the bio-based solution can penetrate effectively. The treatment is most effective when applied in warm, dry weather - ideally above 50°F and with no rain in the forecast. This process is particularly suited for asphalt shingle roofs that are 5 to 15 years old, showing signs of wear but still in good structural condition.

Scharf Fresh Roof takes this process a step further with their patented solution, delivering even more impressive results.

GreenSoy Technology Explained

GreenSoy Technology

Scharf Fresh Roof's GreenSoy Technology enhances traditional rejuvenation methods by not only replenishing lost oils but also improving granule adhesion. These granules are vital for protecting the asphalt, and keeping them securely attached helps shingles maintain their integrity. This restoration allows shingles to regain flexibility, an essential trait for withstanding temperature fluctuations without cracking.

The treatment also improves the roof's resilience to harsh weather conditions, including wind and hail. In fact, shingles treated with this technology experience a 24% reduction in hail damage. Beyond protecting your roof, this process contributes to environmental sustainability by reducing the construction debris and landfill waste associated with full roof replacements.

Benefits of Roof Rejuvenation

Building on the rejuvenation process discussed earlier, let's explore why this treatment is a smart choice for homeowners. Roof rejuvenation not only extends the life of your roof but also enhances its overall performance, restores its appearance, and offers environmentally friendly advantages.

Longer Roof Life and Cost Savings

One of the standout benefits of roof rejuvenation is its ability to add an extra 5–15 years to the lifespan of your asphalt shingles, effectively doubling their remaining service life. This means significant savings for homeowners. While replacing a roof can cost anywhere from $8,000 to $15,000 or more, rejuvenation treatments typically fall between $1,000 and $2,500 - saving you thousands of dollars.

Take, for example, a Maryland homeowner with a 12-year-old roof. By investing $1,800 in a rejuvenation treatment, they extended the roof's life by 10 years and received a 5-year transferable warranty. That’s a practical and cost-effective solution compared to a full replacement.

Improved Protection and Enhanced Appearance

Roof rejuvenation doesn’t just extend the life of your roof - it also improves its resilience. Treated shingles are better equipped to withstand harsh weather conditions, including wind, hail, and UV exposure. Beyond protection, the treatment revitalizes the roof’s surface, removing stains, moss, and algae, while restoring the original color and shine of the shingles. This refreshed look not only boosts curb appeal but also signals that your roof is in excellent condition.

Scharf Fresh Roof's patented GreenSoy Technology takes this a step further by improving durability without requiring a full replacement. With this treatment, you get a roof that performs better and looks great, all while contributing to a more sustainable future.

Environmentally Friendly Benefits

Roof rejuvenation also shines when it comes to environmental impact. Each year, nearly 11 million tons of asphalt shingles end up in U.S. landfills. By extending the life of existing shingles, rejuvenation helps reduce this massive waste while conserving the resources needed to produce new roofing materials. For instance, the Maryland homeowner's decision to rejuvenate their roof kept over 3,000 pounds of shingles out of a landfill.

Scharf Fresh Roof further amplifies these eco-friendly benefits through its dedication to sustainability. Their GreenSoy Technology uses plant-based treatments, and they plant a tree for every roof treated. Additionally, many modern rejuvenation products are made with up to 90% bio-based, food-grade oils, making this process a greener choice for home maintenance. This approach aligns with the growing demand for environmentally conscious solutions in home care.

FAQs

What makes roof rejuvenation a more environmentally friendly option than roof replacement?

Roof rejuvenation offers a greener alternative by restoring your existing asphalt shingles instead of replacing them. This approach cuts down on waste heading to landfills and reduces the need for new materials, helping to conserve resources.

On top of that, rejuvenating your roof decreases the carbon emissions tied to producing, transporting, and disposing of roofing materials. By giving your roof a longer life, this eco-conscious choice not only saves you money but also supports a healthier environment.

What are the best weather conditions for roof rejuvenation, and why does timing matter?

The best weather for roof rejuvenation is dry, with temperatures between 50°F and 80°F. These mild conditions allow the treatment to set and bond effectively with the shingles, ensuring it performs as it should.

Applying the treatment at the wrong time can cause problems. In very cold weather, shingles can become brittle, while extreme heat can make them overly soft. Selecting the right weather not only safeguards your roof but also ensures the rejuvenation process delivers optimal results.

How do I know if my roof can be rejuvenated instead of replaced?

If your asphalt shingles are generally in decent shape but are starting to show signs of aging - like minor wear, reduced flexibility, or fading - they might be suitable for rejuvenation. On the other hand, if you’re dealing with more severe problems such as cracked or curling shingles, missing granules, widespread leaks, or structural damage, a full roof replacement could be the better option.

The best way to decide? Get a professional inspection. An expert can assess your roof's condition and help determine if rejuvenation is a practical choice, saving you the expense of an unnecessary replacement while adding more years to your roof’s lifespan.
