Asphalt shingles are a popular choice for roof installation due to their durability and affordability. However, there are many myths surrounding the roof installation process that can cause confusion. For example, the average cost of roof installation or what to expect with a new roof installation might not be as clear as it seems. 


At Trill Roofing, we specialize in providing professional roof installation services for homeowners in Godfrey, IL, and nearby areas. As a trusted roof installation company, we believe in providing accurate and clear information to help you navigate through the myths and get the facts you need for your roofing project. In this blog, we’ll address the top five myths about asphalt shingle roof installation and give you the answers you need to move forward with confidence.




Myth 1 – All Asphalt Shingles Are the Same

When considering a roof installation, it’s common to assume that all asphalt shingles are alike. In reality, asphalt shingles come in a wide variety of qualities, and not all of them will perform the same over time. It’s important to understand the differences so you can make the best choice for your home.

Material Quality Varies by Manufacturer

Asphalt shingles vary from one another. Depending on the manufacturer, they can differ greatly. Certain shingles are constructed from premium materials, which provide improved performance and a longer lifespan. These high-end shingles are usually composed of thicker asphalt layers, more resilient granules, and improved weather resistance. However, less expensive shingles could have thinner asphalt layers, which means they won't withstand severe weather conditions like strong winds, torrential rain, or extremely high or low temperatures as effectively.

The quality of shingles is determined by several factors, including the type of asphalt saturation, the granule coating, and the base material used. These factors all contribute to how well the shingles protect your home and how long they will last before needing replacement. High-quality shingles are designed to offer better resistance to damage and offer a longer lifespan, making them a reliable investment for your roof.

Warranty Differences Impact Long-Term Value

Warranties play a major role in the long-term value of your roof installation. Many homeowners may not realize that warranties vary greatly between different shingles and manufacturers. Higher-quality shingles typically come with more extended warranties. These warranties often include coverage for issues like weather damage, premature aging, or product defects. This extended warranty means your roof is protected for a longer period, saving you the potential cost of repairs or replacements in the future.

On the flip side, lower-quality shingles often come with shorter warranties, sometimes as short as 20 years. If your shingles fail early, you might be left with costly repairs, which could make the upfront savings of choosing a cheaper product seem less appealing in the long run.

At Trill Roofing, we focus on offering only top-quality asphalt shingles for your new roof installation. Our team of roofing experts carefully selects shingles from trusted manufacturers known for their durability, weather resistance, and long-lasting protection.

Myth 2 – Asphalt Shingles Only Last 10 to 15 Years

A common myth surrounding asphalt shingle roofs is that they only last 10 to 15 years. While it's true that some roofs may have a shorter lifespan, asphalt shingles can last much longer with the right conditions and maintenance. Many shingles are designed to perform effectively for 20 to 30 years and, in some cases, even longer.

Factors That Impact Roof Lifespan

Several factors influence the longevity of an asphalt shingle roof. Ventilation is one of the most important elements. Proper ventilation helps regulate temperature and moisture levels in your attic, which can prevent premature roof damage caused by trapped heat and humidity. 


Additionally, the climate plays a significant role in how long your roof lasts. Areas with extreme weather conditions, such as high winds, heavy rainfall, or intense heat, can cause shingles to wear out faster. 


The quality of the roof installation services is another important factor. Poor installation can lead to various issues that reduce the roof's effectiveness and lifespan, such as improper nailing, insufficient underlayment, or misalignment of shingles. These issues can compromise your roof's durability and cause premature damage.

Proper Installation Extends Performance

The way your new roof installation is carried out directly impacts its lifespan. Proper roof installation techniques, such as correct nailing, precise alignment, and the use of high-quality underlayment, can greatly enhance the roof's durability. A professionally installed roof is better equipped to handle weather conditions like heavy rain, high winds, or snow. By making sure that all elements are properly installed and aligned, your roof will perform more efficiently and require fewer repairs over time. This careful installation helps prevent issues such as leaks, shingle lifting, and water damage, all of which can remarkably shorten the life of your roof.

Routine Maintenance Recommendations

Regular maintenance plays a key role in extending the life of your asphalt roof. It's important to schedule routine inspections to identify any potential problems early, especially after severe weather events. Regularly cleaning your gutters helps prevent water backup, which can cause shingles to degrade or even lead to leaks. If you notice damaged or missing shingles, it's important to replace them quickly to prevent further damage. 

Addressing small issues promptly, such as fixing leaks or sealing gaps, can also prevent larger, more costly repairs down the line. By staying on top of these tasks, you can maximize the performance and lifespan of your roof.

At Trill Roofing, we recommend annual roof inspections to make sure that your roof remains in great condition for as long as possible. By providing high-quality roof installation services and routine maintenance, we help you get the most out of your asphalt shingle roof.

Myth 3 – A New Roof Can Be Installed in a Single Afternoon

One of the most common myths about roof installation is that it can be completed in just a single afternoon. While some smaller tasks like roof repairs may be finished in a short time, the reality of new roof installation is much more involved. The process requires careful planning, the right materials, and skilled labor, all of which contribute to a longer timeline.

What a Professional Installation Timeline Looks Like

In reality, the timeline for a roof installation can vary based on several factors. For a standard new roof installation on a typical single-story house, the job generally takes about 1 to 2 days. This includes the removal of old roofing, the installation of new shingles, and all necessary inspections and adjustments. However, for larger or more complex roofs, such as multi-story homes or those requiring extra work (like structural repairs), the process can take up to 3 days.


The average cost of roof installation also plays a role in determining the timeline. A more expensive, higher-quality roofing material may require extra time for careful handling and installation. Similarly, roofs with unique designs or features may require additional work, adding time to the project.

Factors That Can Delay the Process

There are a few factors that can delay the timeline for roof installation services. The weather is one of the most common. Rain, snow, or extreme winds can halt roofing work, as it’s unsafe to install shingles in such conditions. 


Another factor is the roof size. Larger roofs naturally take more time to complete due to the greater number of shingles and the more complex layout. 


Additionally, if the roof requires additional repairs—such as fixing damaged decking or replacing old flashing—this will add to the installation time. Removing old roofing materials can also extend the project, especially if the roof has multiple layers that need to be stripped away before new shingles are applied.


At Trill Roofing, we pride ourselves on offering clear communication and a well-structured process for every roof installation. From the initial consultation to the final inspection, we provide you with a detailed timeline that outlines each phase of the project. We make sure that you know exactly what to expect and when to expect it so there are no surprises during the process.

Myth 4 – Roof Installation Is Just About Laying Shingles

A common misconception about roof installation is that it’s simply about laying shingles on top of your home. While shingles are a key part of the process, a complete roof installation involves multiple components and steps. A well-installed roof is more than just the visible shingles; it’s a system that protects your home from the elements.

Components Involved in a Full Roofing System

A proper new roof installation involves more than just placing shingles. A complete roofing system consists of several important components that all work together to protect your home. In addition to the shingles, your roof will require underlayment, flashing, ridge vents, and ice barriers. These components help to prevent water from entering your home, reduce the chances of leaks, and provide structural stability. 

Flashing, for example, is installed around roof penetrations (like chimneys and vents) to prevent water from seeping in. Ice barriers are added in areas prone to freezing temperatures to prevent ice dams, which can cause significant damage.

Why Ventilation and Underlayment Matter

Proper ventilation and underlayment are important for a long-lasting roof. Ventilation allows airflow in the attic, preventing heat buildup that can cause shingles to age quickly. Without adequate ventilation, shingles may wear out more rapidly, reducing the overall lifespan of your roof.


On the other hand, underlayment acts as an additional protective layer beneath the shingles. It serves as a barrier against leaks, moisture, and water damage, preventing harmful elements from getting through the roof and causing issues inside your home. A quality underlayment helps maintain the integrity of the roof, especially in areas exposed to harsh weather.

Code Compliance and Long-Term Protection

Every roof installation must adhere to local building codes and regulations. At Trill Roofing, we take code compliance seriously to make sure your roof is not only safe but also legally sound. We follow all the necessary guidelines and use the highest quality materials to meet durability and safety standards. By doing so, we guarantee that your roof will stand up to the test of time and provide long-term protection for your home. This attention to detail also guarantees that your roof installation will hold up under extreme weather conditions, giving you lasting peace.

Myth 5 – Any Contractor Can Handle Asphalt Roof Installation

When it comes to asphalt roof installation, many homeowners make the mistake of thinking that any contractor can handle the job. However, roofing is a specialized skill that requires expertise, experience, and knowledge of the materials and installation techniques. Choosing the wrong contractor can lead to costly mistakes and, ultimately, a roof that doesn’t perform as it should.

The Risks of Choosing the Wrong Roof Installation Company

Not all contractors have the right skills to install a roof properly. Some may take shortcuts, use inferior materials, or skip important steps during installation. This can result in serious issues, such as leaks, poor insulation, and roof damage. These problems can shorten the life of your roof and lead to expensive repairs. 


When you hire a professional roof installation company, you’re investing in quality craftsmanship, reliability, and a roof that will protect your home for years. By choosing a trusted company, you reduce the risk of encountering problems that could arise from improper installation.

What Sets Professional Installers Apart

Skilled installers are well-trained in asphalt shingle installation. They are familiar with the proper techniques for placing shingles, such as correct alignment and overlap, which are important for the roof’s performance. They also have a strong understanding of the materials needed to build a secure roof, including the most suitable underlayment and flashing materials for different climates.


Also, experienced contractors follow local building codes to make sure your roof complies with safety and legal standards. By hiring a professional roof installation company, you can trust that the job will be completed correctly the first time, preventing the need for costly rework.

Questions to Ask Before Hiring a Roof Installation Company

Before committing to a roof installation company, here are some important questions to ask to guarantee that you’re choosing the right fit:

  1. Are you licensed and insured?Make sure that the contractor holds the necessary licenses and insurance to protect both you and them in case of accidents.

  2. What is the typical average cost of roof installation for a house similar to mine?Knowing the cost can help you gauge whether the pricing is fair and within your budget.

  3. What kind of warranty do you provide for your work?A warranty is important for peacefulness, as it shows the contractor stands behind their work.

  4. Do you have references from past clients?Speaking with previous clients gives you insight into the contractor’s quality of work and professionalism.
