Asphalt Shingle Replacement: A Comprehensive Guide
Introduction to Asphalt Shingle Replacement
Asphalt shingles are the most common roofing material in North America, prized for their affordability, durability, and ease of installation. However, even the best asphalt shingles have a lifespan, and eventually, they will need to be replaced. Understanding when and how to replace your asphalt shingles is crucial for maintaining the integrity and longevity of your home. This comprehensive guide will walk you through every aspect of asphalt shingle replacement, from identifying signs of damage to choosing the right shingles and hiring a qualified contractor.
Replacing your roof is a significant investment, but it’s one that protects your home from the elements and prevents costly damage down the line. Ignoring a failing roof can lead to leaks, structural damage, and even health problems due to mold and mildew growth. Therefore, proactive maintenance and timely replacement are essential.
Why Asphalt Shingles Need Replacing
Asphalt shingles are exposed to the harsh realities of weather, including sun, rain, wind, and extreme temperature fluctuations. Over time, these elements take their toll, leading to degradation and eventual failure. Several factors contribute to the need for asphalt shingle replacement:
Age of the Shingles
The lifespan of asphalt shingles typically ranges from 15 to 30 years, depending on the quality of the shingles and the climate in which they are installed. Architectural or dimensional shingles generally last longer than traditional three-tab shingles. If your roof is nearing the end of its expected lifespan, it’s time to start considering replacement.
Visible Signs of Damage
One of the most obvious indicators of a failing roof is visible damage. Look for these common signs:
Curling or Buckling: This occurs when the edges of the shingles lift up, exposing the underlayment. Curling and buckling are often caused by prolonged exposure to sunlight and temperature changes.
Granule Loss: Asphalt shingles are coated with granules that protect the asphalt layer from UV radiation. As the shingles age, these granules begin to fall off, leaving the asphalt exposed. Excessive granule loss can be seen in gutters and around downspouts.
Cracking: Cracks in the shingles are a sign that the asphalt has become brittle and is no longer able to withstand the elements. Cracks can allow water to penetrate the roof, leading to leaks and structural damage.
Missing Shingles: Missing shingles are a clear indication that your roof is compromised. Missing shingles expose the underlayment and leave your roof vulnerable to water damage.
Algae Growth: Algae growth, especially in humid climates, can degrade the shingles and shorten their lifespan. While algae growth might not immediately cause leaks, it can detract from the appearance of your roof and indicate underlying moisture problems.
Leaks and Water Damage
Leaks in the attic or ceiling are a serious sign of roof damage. Water stains, discoloration, and mold growth are all indicators of water penetration. Even small leaks can cause significant damage over time, so it’s important to address them promptly.
Storm Damage
Severe weather events, such as hail storms, high winds, and heavy snow, can cause significant damage to asphalt shingles. Hail can dent or fracture shingles, while high winds can tear them off the roof. After a major storm, it’s important to inspect your roof for damage.
Steps to Take Before Asphalt Shingle Replacement
Before embarking on an asphalt shingle replacement project, there are several important steps to take to ensure a smooth and successful process:
Assess the Extent of the Damage
A thorough assessment of the roof’s condition is crucial. This involves a visual inspection of the roof from the ground and, if safe to do so, from the roof itself. Look for the signs of damage mentioned above, such as curling, cracking, granule loss, and missing shingles. Pay close attention to areas that are prone to leaks, such as around chimneys, vents, and skylights.
Determine if Replacement is Necessary or if a Repair Will Suffice
In some cases, minor damage can be repaired rather than requiring a full roof replacement. If only a few shingles are damaged, a repair might be a more cost-effective solution. However, if the damage is widespread or the shingles are nearing the end of their lifespan, replacement is usually the best option. Consider the age and overall condition of the roof when making this decision.
Research Different Types of Asphalt Shingles
Asphalt shingles come in a variety of styles, colors, and quality levels. Research the different types available to determine which one best suits your needs and budget. Common types include:
Three-Tab Shingles: These are the most basic and affordable type of asphalt shingle. They have a flat, uniform appearance and are typically less durable than architectural shingles.
Architectural or Dimensional Shingles: These shingles are thicker and more durable than three-tab shingles. They have a textured, layered appearance that mimics the look of wood shakes or slate.
Luxury Shingles: These are the highest-quality asphalt shingles, designed to resemble slate or tile. They are the most expensive option but offer superior durability and aesthetic appeal.
Consider factors such as the climate in your area, the style of your home, and your budget when choosing shingles. Look for shingles with a good warranty and a proven track record of performance.
Check Local Building Codes and Regulations
Before starting any roofing project, it’s important to check local building codes and regulations. Many municipalities require permits for roof replacements, and there may be specific requirements for the type of shingles that can be used or the installation methods that must be followed. Contact your local building department to obtain the necessary permits and ensure that your project complies with all applicable regulations.
Get Multiple Quotes from Roofing Contractors
It’s always a good idea to get multiple quotes from different roofing contractors before making a decision. This allows you to compare prices, services, and warranties. Be sure to choose reputable contractors with experience in asphalt shingle replacement. Ask for references and check online reviews to get a sense of their quality of work and customer service.
Choosing the Right Asphalt Shingles
Selecting the appropriate asphalt shingles is paramount to the longevity and aesthetics of your new roof. Here’s a more detailed look at the types of shingles and factors to consider:
Understanding Shingle Types in Detail
Three-Tab Shingles: These are the traditional and most economical option. They are characterized by their uniform, flat appearance, with three distinct tabs per shingle. While they offer basic protection and are relatively easy to install, their lifespan is typically shorter compared to architectural shingles, often ranging from 15 to 20 years. They are a good choice for homeowners on a tight budget or for smaller, less complex roofs.
Architectural or Dimensional Shingles: These shingles, also known as laminated or composite shingles, are a significant upgrade from three-tab shingles. They feature multiple layers of asphalt that are laminated together, creating a thicker and more durable shingle with a three-dimensional appearance. They offer better wind resistance, impact resistance, and overall longevity, often lasting 25 to 30 years or more. Their textured surface also adds visual interest to the roof, enhancing the curb appeal of your home.
Luxury Shingles: These represent the premium segment of asphalt shingles, designed to mimic the look of natural slate, cedar shake, or tile roofs. They are typically the thickest and heaviest asphalt shingles, offering exceptional durability and a high-end aesthetic. Luxury shingles can last for 30 years or more and are a great choice for homeowners who want the look of a premium roofing material without the associated cost and maintenance.
Factors to Consider When Selecting Shingles
Climate: The climate in your area should be a major factor in your shingle selection. In areas with high winds or frequent storms, consider shingles with a high wind resistance rating. In areas with extreme temperatures, choose shingles that are designed to withstand thermal expansion and contraction. In areas with high humidity, look for shingles that are resistant to algae growth.
Wind Resistance: Shingles are rated for their ability to withstand wind. Look for shingles with a wind resistance rating that meets or exceeds the requirements of your local building code. High-wind areas may require shingles with a special sealant or fastening system.
Impact Resistance: Impact-resistant shingles are designed to withstand damage from hail and other impacts. These shingles have a higher impact resistance rating and can help to protect your roof from damage during severe weather. Some insurance companies offer discounts for homes with impact-resistant roofs.
Color: The color of your shingles can have a significant impact on the appearance of your home. Choose a color that complements the style of your home and the surrounding landscape. Lighter-colored shingles can help to reflect sunlight and keep your home cooler in the summer, while darker-colored shingles can absorb heat and keep your home warmer in the winter.
Warranty: Pay close attention to the warranty offered by the shingle manufacturer. A good warranty can protect you from defects in materials or workmanship. Be sure to understand the terms and conditions of the warranty, including what is covered and what is not.
Budget: Asphalt shingle prices can vary widely, depending on the type, quality, and brand. Set a budget for your roofing project and choose shingles that fit within your price range. Remember that it’s often worth it to invest in higher-quality shingles, as they will typically last longer and require less maintenance.
Finding and Hiring a Roofing Contractor
Selecting a qualified and reputable roofing contractor is crucial for a successful asphalt shingle replacement project. Here’s how to find and vet potential contractors:
Where to Look for Roofing Contractors
Referrals: Ask friends, family, neighbors, and colleagues for recommendations. Personal referrals are often the most reliable way to find a good contractor.
Online Directories: Use online directories such as Yelp, Angie’s List, and the Better Business Bureau to search for roofing contractors in your area. Read reviews and check ratings to get a sense of their reputation.
Manufacturer Websites: Some shingle manufacturers have lists of certified contractors who are trained and authorized to install their products. These contractors often offer extended warranties and guarantees.
Local Associations: Contact local roofing associations or trade groups for a list of member contractors. These organizations often have strict membership requirements and codes of ethics.
What to Look for in a Roofing Contractor
License and Insurance: Make sure the contractor is licensed and insured. A license demonstrates that the contractor has met the requirements of your state or local government. Insurance protects you from liability if a worker is injured on your property or if your property is damaged during the project.
Experience: Choose a contractor with experience in asphalt shingle replacement. Ask how many years they have been in business and how many roofing projects they have completed. A contractor with a proven track record is more likely to deliver a high-quality result.
References: Ask for references from past clients and contact them to get feedback on the contractor’s work. Ask about their experience with the contractor, the quality of the workmanship, and the level of customer service.
Warranty: Ask about the contractor’s warranty on their work. A good contractor will stand behind their work and offer a warranty that covers defects in workmanship. Make sure you understand the terms and conditions of the warranty before signing a contract.
Communication: Choose a contractor who communicates clearly and responds promptly to your questions and concerns. Good communication is essential for a smooth and successful project.
Questions to Ask Potential Contractors

The Asphalt Shingle Replacement Process
Understanding the process of asphalt shingle replacement can help you prepare for the project and ensure that it is completed successfully. Here is a step-by-step overview:
Preparation
Protecting Your Property: The contractor should take steps to protect your property from damage during the project. This may include covering landscaping, siding, and other vulnerable areas with tarps or plywood.
Removing the Old Shingles: The contractor will remove the old shingles, underlayment, and any other roofing materials down to the roof deck. This is a noisy and messy process, so be prepared for some disruption.
Inspecting the Roof Deck: The contractor will inspect the roof deck for damage, such as rot or decay. Any damaged areas will need to be repaired or replaced before the new shingles are installed.
Installation
Installing Underlayment: Underlayment is a layer of waterproof material that is installed on top of the roof deck to protect it from moisture. The contractor will install the underlayment according to the manufacturer’s instructions.
Installing Drip Edge: Drip edge is a metal flashing that is installed along the edges of the roof to prevent water from running behind the fascia. The contractor will install the drip edge before installing the shingles.
Installing Shingles: The contractor will install the shingles according to the manufacturer’s instructions. This involves overlapping the shingles and nailing them to the roof deck. The contractor will also install flashing around chimneys, vents, and skylights to prevent leaks.
Clean Up: The contractor will clean up the job site, removing all debris and disposing of the old roofing materials. A thorough clean-up is essential to prevent injuries and protect your property.
Inspection
Final Walk-Through: After the project is completed, the contractor should conduct a final walk-through with you to ensure that you are satisfied with the work. This is your opportunity to identify any issues or concerns.
Final Inspection: Some municipalities require a final inspection to ensure that the roof was installed in accordance with local building codes. The contractor should schedule the final inspection and address any issues that are identified.
Maintaining Your New Asphalt Shingle Roof
Proper maintenance can extend the life of your new asphalt shingle roof and prevent costly repairs. Here are some tips for maintaining your roof:
Regular Inspections
Inspect your roof at least twice a year, in the spring and fall. Look for signs of damage, such as curling, cracking, granule loss, and missing shingles. Pay close attention to areas that are prone to leaks, such as around chimneys, vents, and skylights.
Clean Your Gutters
Keep your gutters clean and free of debris. Clogged gutters can cause water to back up and damage your roof. Clean your gutters at least twice a year, or more often if you live in an area with heavy tree cover.
Trim Overhanging Branches
Trim overhanging branches to prevent them from damaging your roof. Branches can rub against the shingles and cause them to wear prematurely. They can also drop leaves and debris on your roof, which can clog your gutters and promote algae growth.
Remove Moss and Algae
Remove moss and algae from your roof. Moss and algae can trap moisture and damage the shingles. You can remove them with a soft brush and a solution of water and bleach. Be careful not to damage the shingles when cleaning them.
Repair Damage Promptly
Repair any damage to your roof promptly. Small leaks can cause significant damage over time, so it’s important to address them quickly. Contact a qualified roofing contractor to repair any damage.
Avoid Walking on Your Roof
Avoid walking on your roof unless it is absolutely necessary. Walking on your roof can damage the shingles. If you must walk on your roof, wear soft-soled shoes and avoid stepping on the edges of the shingles.
Cost Considerations for Asphalt Shingle Replacement
Understanding the costs associated with asphalt shingle replacement is crucial for budgeting and planning your project. Several factors influence the overall expense:
Factors Affecting the Cost of Replacement
Roof Size and Complexity: Larger roofs and those with complex designs (multiple gables, dormers, skylights) will naturally cost more to replace due to increased labor and material requirements.
Type of Shingles: As previously discussed, the type of shingles you choose significantly impacts the cost. Three-tab shingles are the most affordable, while architectural and luxury shingles are more expensive.
Underlayment and Other Materials: The quality and type of underlayment, flashing, and other roofing components also contribute to the overall cost. Using high-quality materials can increase the upfront expense but may result in long-term savings due to improved durability and performance.
Labor Costs: Labor costs can vary depending on the contractor’s experience, the complexity of the project, and the location. It’s essential to get multiple quotes to compare labor rates.
Removal and Disposal of Old Roofing Materials: The cost of removing and disposing of the old shingles and roofing materials is typically included in the contractor’s estimate. However, it’s important to confirm this and understand any additional fees that may apply.
Roof Deck Repairs: If the roof deck is damaged or needs repairs, this will add to the overall cost. The extent of the damage will determine the amount of repair work required.
Permits and Inspections: Building permits and inspections are required in many municipalities and can add to the overall cost of the project.
Average Cost Ranges
The average cost of asphalt shingle replacement can vary widely depending on the factors mentioned above. However, here are some general cost ranges:
Three-Tab Shingles: $3 to $5 per square foot
Architectural or Dimensional Shingles: $4 to $8 per square foot
Luxury Shingles: $6 to $12 per square foot
These are just estimates, and the actual cost may vary depending on your specific circumstances. It’s always best to get multiple quotes from roofing contractors to get a more accurate estimate.
Ways to Save Money on Asphalt Shingle Replacement
Get Multiple Quotes: As mentioned earlier, getting multiple quotes from different contractors is essential for comparing prices and finding the best deal.
Choose Affordable Shingles: If you’re on a tight budget, consider choosing three-tab shingles, which are the most affordable option.
Schedule the Project During Off-Season: Roofing contractors may offer discounts during the off-season (typically fall or winter) when demand is lower.
Consider DIY (If You’re Experienced): If you have experience in roofing, you may be able to save money by doing the project yourself. However, this is not recommended for inexperienced homeowners, as it can be dangerous and may void the warranty on the shingles.
Look for Rebates and Incentives: Some manufacturers and local governments offer rebates and incentives for installing energy-efficient roofing materials.
When to Consider an Alternative Roofing Material
While asphalt shingles are a popular and cost-effective roofing option, there are situations where considering alternative materials might be beneficial. Here’s a look at some reasons and alternatives:
Reasons to Explore Alternatives
Longevity: Asphalt shingles typically last 15-30 years, whereas other materials can last much longer. If you’re looking for a roofing material that will last for 50 years or more, consider alternatives like slate, tile, or metal.
Aesthetics: While asphalt shingles come in a variety of colors and styles, they may not offer the same aesthetic appeal as other materials. If you’re looking for a unique or high-end look, consider alternatives like slate, tile, or wood shake.
Environmental Impact: Asphalt shingles are made from petroleum-based products, which are not environmentally friendly. If you’re concerned about the environmental impact of your roofing material, consider alternatives like recycled metal, wood shake, or clay tile.
Energy Efficiency: Some roofing materials are more energy-efficient than asphalt shingles. For example, metal roofs can reflect sunlight and keep your home cooler in the summer, while cool roofing systems are designed to reduce heat absorption.
Alternative Roofing Materials
Metal Roofing: Metal roofs are durable, long-lasting, and energy-efficient. They come in a variety of styles and colors and can last for 50 years or more. However, they can be more expensive than asphalt shingles.
Tile Roofing: Tile roofs are durable, fire-resistant, and aesthetically appealing. They can last for 50 years or more and come in a variety of styles and colors. However, they can be heavy and require a strong roof structure.
Slate Roofing: Slate roofs are one of the most durable and long-lasting roofing materials available. They can last for 100 years or more and offer a classic, elegant look. However, they are also one of the most expensive roofing materials.
Wood Shake Roofing: Wood shake roofs offer a rustic, natural look. They can last for 30-50 years with proper maintenance. However, they are more expensive than asphalt shingles and require regular treatment to prevent rot and insect damage.
Conclusion
Asphalt shingle replacement is a significant home improvement project that requires careful planning and execution. By understanding the signs of damage, choosing the right shingles, hiring a qualified contractor, and maintaining your new roof properly, you can ensure that your home is protected from the elements for years to come. While asphalt shingles are a popular and cost-effective option, consider alternative roofing materials if you’re looking for greater longevity, unique aesthetics, or improved environmental performance. Remember to prioritize safety and compliance with local building codes throughout the entire process.
