Replace Asphalt Shingle Roof

Your roof is your home’s primary defense against the elements. It shelters you from rain, snow, wind, and the harsh rays of the sun. Over time, even the sturdiest roofs succumb to wear and tear. Asphalt shingle roofs, while popular and relatively affordable, have a lifespan that typically ranges from 15 to 30 years, depending on the quality of the shingles, the climate, and the quality of the installation. Knowing when to replace your asphalt shingle roof is crucial for protecting your home and preventing costly damage down the road.

Recognizing the Signs: When to Replace Your Asphalt Shingle Roof

Determining whether you need a roof replacement isn’t always straightforward. Sometimes the damage is obvious, like a gaping hole after a storm. Other times, the signs are more subtle and require a keen eye. Here’s a breakdown of the key indicators that suggest it’s time for a new roof:

Age of the Roof

As mentioned earlier, the average lifespan of an asphalt shingle roof is 15 to 30 years. If your roof is nearing or has exceeded this age range, it’s time to start considering a replacement, regardless of whether you see any visible signs of damage. Even if the shingles look okay from the ground, the underlying materials may be deteriorating.

Curling, Cracking, and Missing Shingles

One of the most obvious signs of a failing roof is the presence of curling, cracking, or missing shingles. These issues can be caused by a variety of factors, including exposure to extreme temperatures, UV radiation, and wind. Curling shingles lose their ability to shed water effectively, while cracked shingles can allow water to penetrate the underlayment. Missing shingles, of course, leave your roof completely vulnerable to the elements.

Granule Loss

Asphalt shingles are coated with granules that protect the asphalt from UV radiation and provide fire resistance. Over time, these granules begin to loosen and wash away. You may notice granules accumulating in your gutters or at the base of your downspouts. Significant granule loss exposes the asphalt to the sun, causing it to dry out and crack, ultimately shortening the lifespan of your roof.

Dark Streaks and Stains

Dark streaks and stains on your roof are often caused by algae growth. While algae itself doesn’t necessarily damage the shingles, it can be unsightly and indicate that your roof is retaining moisture, which can lead to other problems. In some cases, the algae can contribute to the deterioration of the shingles over time.

Sagging Roof Deck

A sagging roof deck is a serious issue that requires immediate attention. It indicates that the underlying structure of your roof is compromised, potentially due to water damage or rot. A sagging roof is a significant safety hazard and should be inspected by a professional immediately. This often means the underlying plywood is water damaged and needs to be replaced. This is more costly as it is more labor intensive.

Leaks in the Attic

Water stains on your ceiling or walls are a clear sign of a roof leak. Even if you can’t pinpoint the exact source of the leak, it’s important to address the problem promptly. Leaks can cause significant damage to your home’s structure, leading to mold growth, wood rot, and other costly repairs. Check your attic after a heavy rain to look for signs of water intrusion.

Damaged Flashing

Flashing is the metal material that’s installed around chimneys, vents, and other roof penetrations to prevent water from seeping in. Damaged, rusted, or improperly installed flashing can allow water to enter your home, leading to leaks and other problems. It is especially important that step flashing is installed correctly where the roof meets a wall. These are prone to leaks and are often the source of water damage.

Moss Growth

While moss may look charming, it can actually damage your asphalt shingles. Moss retains moisture, which can weaken the shingles and cause them to deteriorate more quickly. It can also create a breeding ground for other organisms that can further damage your roof. Moss removal is a task that should be done by a professional to avoid damaging the roof.

The Roof Replacement Process: A Step-by-Step Guide

Replacing an asphalt shingle roof is a significant undertaking that requires careful planning and execution. Here’s a general overview of the steps involved in the process:

1. Inspection and Assessment

The first step is to have your roof inspected by a qualified roofing contractor. The contractor will assess the condition of your roof, identify any areas of damage, and provide you with a detailed estimate for the replacement. They will also discuss your options for shingle types, colors, and other features.

2. Selecting a Roofing Contractor

Choosing the right roofing contractor is essential for a successful roof replacement. Look for a contractor that is licensed, insured, and has a proven track record of quality workmanship. Ask for references and check online reviews to get a sense of their reputation. Get multiple bids to compare prices and services. Make sure the contractor clearly outlines the scope of work, materials to be used, and warranty information in writing.

3. Obtaining Permits

In most jurisdictions, you’ll need to obtain a permit before you can begin roof replacement. Your roofing contractor should be able to handle the permit application process for you. The permit ensures that the work is done in accordance with local building codes.

4. Tearing Off the Old Roof

The next step is to tear off the old roofing materials, including the shingles, underlayment, and flashing. This is a messy and labor-intensive process. The contractor will typically use specialized tools to remove the shingles quickly and efficiently. They should also take precautions to protect your property from damage during the tear-off process. Proper disposal of the old roofing materials is also important.

5. Inspecting the Roof Deck

Once the old roof is removed, the contractor will inspect the roof deck for any signs of damage, such as rot or water damage. Any damaged decking will need to be replaced before the new roof can be installed. This step is crucial for ensuring the long-term integrity of your roof. Often this requires new plywood to be installed.

6. Installing Underlayment

Underlayment is a water-resistant barrier that is installed over the roof deck. It provides an extra layer of protection against leaks and helps to prevent water from damaging the underlying structure. There are different types of underlayment available, including felt paper and synthetic underlayment. Synthetic underlayment is generally more durable and water-resistant than felt paper.

7. Installing Flashing

Flashing is installed around chimneys, vents, and other roof penetrations to prevent water from seeping in. The flashing is typically made of metal, such as aluminum or copper. It’s important to ensure that the flashing is properly installed to prevent leaks. This is a critical step that requires attention to detail.

8. Installing the New Shingles

The final step is to install the new asphalt shingles. The shingles are typically installed in overlapping rows, starting at the bottom of the roof and working your way up. The contractor will use nails or staples to secure the shingles to the roof deck. Proper installation is crucial for ensuring that the shingles are weather-tight and will last for many years.

9. Cleanup and Inspection

After the new roof is installed, the contractor will clean up the work site and remove all debris. They will also conduct a final inspection to ensure that the roof is properly installed and that there are no defects. A good contractor will walk you through the finished product and answer any questions you may have.

Choosing the Right Asphalt Shingles: Types and Considerations

Asphalt shingles come in a variety of styles, colors, and materials. Here’s a look at the different types of asphalt shingles and the factors you should consider when making your selection:

3-Tab Shingles

3-tab shingles are the most basic and affordable type of asphalt shingle. They are characterized by their simple, flat design with three tabs. 3-tab shingles are typically less durable than other types of asphalt shingles and have a shorter lifespan. They are a good option for homeowners on a tight budget.

Architectural Shingles (Dimensional Shingles)

Architectural shingles, also known as dimensional shingles, are a more premium type of asphalt shingle. They have a multi-layered design that creates a more textured and visually appealing look. Architectural shingles are typically more durable than 3-tab shingles and have a longer lifespan. They are a popular choice for homeowners who want a more stylish and long-lasting roof.

Premium Shingles

Premium shingles are the highest quality type of asphalt shingle. They are made from the finest materials and are designed to withstand extreme weather conditions. Premium shingles often have features such as impact resistance and algae resistance. They are the most expensive type of asphalt shingle, but they offer the best performance and longevity.

Considerations When Choosing Shingles

  • Climate: Consider the climate in your area when choosing shingles. If you live in an area with harsh weather conditions, such as high winds or heavy snowfall, you’ll need to choose shingles that are designed to withstand those conditions.
  • Budget: Asphalt shingles vary in price, so it’s important to consider your budget when making your selection. 3-tab shingles are the most affordable, while premium shingles are the most expensive.
  • Aesthetics: Choose shingles that complement the style of your home. Asphalt shingles come in a variety of colors and styles, so you can find shingles that match your home’s exterior.
  • Warranty: Look for shingles that come with a good warranty. A good warranty will protect you against defects in materials and workmanship.
  • Energy Efficiency: Consider cool roof shingles that reflect sunlight and reduce heat absorption. This can help lower your energy bills during the summer months.

Finding a Qualified Roofing Contractor: What to Look For

Choosing the right roofing contractor is just as important as choosing the right shingles. Here’s what to look for when hiring a roofing contractor:

License and Insurance

Make sure the contractor is licensed and insured. A license ensures that the contractor has met the necessary qualifications to perform roofing work in your area. Insurance protects you from liability in case of accidents or damage that occur during the roof replacement process. Ask for proof of both license and insurance.

Experience and Reputation

Choose a contractor with a proven track record of quality workmanship. Ask for references and check online reviews to get a sense of their reputation. Look for a contractor who has been in business for several years and has a solid portfolio of completed projects.

Detailed Estimate

Get a detailed estimate in writing before hiring a contractor. The estimate should clearly outline the scope of work, materials to be used, and the total cost of the project. Be wary of contractors who provide estimates that are significantly lower than other bids. This could be a sign of substandard materials or workmanship.

Warranty

Make sure the contractor offers a warranty on their work. A good warranty will protect you against defects in materials and workmanship for a specified period of time. Read the warranty carefully to understand what is covered and what is not.

Communication and Customer Service

Choose a contractor who is responsive, communicative, and provides excellent customer service. You should feel comfortable asking questions and expressing your concerns. A good contractor will keep you informed throughout the roof replacement process and will be available to address any issues that may arise.

Local Presence

Hiring a local roofing contractor can be beneficial. They are familiar with local building codes and weather patterns. They are also more likely to be responsive to your needs and provide timely service. They also have a reputation to maintain in your community.

Cost of Replacing an Asphalt Shingle Roof: Factors to Consider

The cost of replacing an asphalt shingle roof can vary depending on a number of factors, including:

Roof Size and Complexity

The larger and more complex your roof, the more it will cost to replace. A roof with multiple gables, dormers, or skylights will require more labor and materials, increasing the overall cost.

Shingle Type

The type of shingles you choose will also affect the cost of the project. 3-tab shingles are the most affordable, while premium shingles are the most expensive.

Underlayment Type

Synthetic underlayment is generally more expensive than felt paper, so the type of underlayment you choose will also affect the cost.

Labor Costs

Labor costs can vary depending on the location and the contractor you choose. Be sure to get multiple bids to compare prices.

Removal and Disposal Costs

The cost of removing and disposing of the old roofing materials can also add to the overall cost of the project.

Additional Repairs

If your roof deck or flashing needs to be repaired or replaced, this will add to the cost of the project.

Permits and Fees

You’ll also need to factor in the cost of permits and fees, which can vary depending on your location.

To get an accurate estimate of the cost of replacing your asphalt shingle roof, it’s best to get multiple bids from qualified roofing contractors.

Extending the Lifespan of Your New Asphalt Shingle Roof: Maintenance Tips

Once you’ve invested in a new asphalt shingle roof, it’s important to take steps to maintain it properly to extend its lifespan. Here are some tips:

Regular Inspections

Inspect your roof regularly, especially after severe weather events. Look for any signs of damage, such as missing, cracked, or curling shingles. Address any problems promptly to prevent further damage.

Clean Gutters

Keep your gutters clean and free of debris. Clogged gutters can cause water to back up onto your roof, leading to leaks and other problems.

Trim Trees

Trim trees that overhang your roof. Branches can fall and damage your shingles, and leaves can accumulate on your roof and trap moisture.

Remove Moss and Algae

Remove moss and algae from your roof regularly. Moss and algae can retain moisture and damage your shingles. There are specialized cleaning solutions that can be used to remove moss and algae without damaging the roof.

Professional Maintenance

Consider hiring a professional roofing contractor to perform regular maintenance on your roof. A professional can identify and address potential problems before they become serious.

Attic Ventilation

Ensure proper attic ventilation. Proper ventilation helps regulate the temperature in your attic and prevent moisture buildup, which can damage your roof from the inside out.

DIY vs. Professional Roof Replacement: Is It Worth It?

While it may be tempting to replace your asphalt shingle roof yourself to save money, it’s generally not recommended unless you have significant roofing experience. Roof replacement is a complex and potentially dangerous task that requires specialized skills and equipment. Here’s a look at the pros and cons of DIY vs. professional roof replacement:

DIY Roof Replacement

Pros:

  • Lower cost (potentially)
  • Sense of accomplishment

Cons:

  • Time-consuming
  • Physically demanding
  • Potentially dangerous
