Signs That You Need to Replace Your Shingles

Are your asphalt shingles looking a little rough around the edges? Here are some signs that you may need to replace your roof shingles:

Age: Asphalt shingles typically last around 20-25 years. If your roof is nearing this age range, it’s time to start considering a replacement, even if there are no visible signs of damage.
Curling or Buckling: Shingles that are curling or buckling are a clear sign of weathering and are no longer providing adequate protection.
Missing Shingles: Missing shingles leave your roof vulnerable to water damage and should be replaced promptly.
Granule Loss: If you notice an excessive amount of granules in your gutters or around your property, it’s a sign that your shingles are deteriorating.
Leaks or Water Damage: Water stains on your ceiling or walls indicate that your roof is compromised and needs attention.
Moss or Algae Growth: While not necessarily indicative of immediate damage, moss or algae growth can signal moisture retention, which can lead to deterioration over time.

DIY vs. Hiring a Professional:

Before diving into the process of shingle installation, it’s essential to consider whether you want to tackle the project yourself or hire a professional. Here are some pros and cons of each option:

DIY Approach

Are you a handy homeowner? You may be interested in taking on the task of a roof replacement on your own! Here are a few of the pros and cons to consider:

👍 Pros:

Cost-saving: Doing it yourself can save you money on labor costs.
Sense of accomplishment: Completing a DIY project can be rewarding.
Flexibility: You can work at your own pace and schedule.

👎 Cons:

Lack of expertise: Roofing can be complex, and DIYers may lack the necessary knowledge and experience.
Safety concerns: Working at heights poses risks, especially without proper safety equipment.
Time-consuming: The process can be time-consuming, especially for inexperienced individuals.

Hiring a Professional Roofing Contractor

Most homeowners tend to rely on the expertise of a roofing contractor when it comes to replacing their roofing materials. Here are some of the reasons why:

✅ Pros:

Expertise: Professional roofers have the skills and knowledge to ensure the job is done correctly.
Safety: Roofing professionals are equipped with the necessary safety gear and precautions.
Time-saving: Professionals can complete the job more quickly and efficiently.

❌ Cons:

Cost: Hiring a professional can be more expensive than doing it yourself.
Dependency: You’ll need to rely on the availability and schedule of the roofing company.

Ultimately, the decision between DIY and hiring a professional depends on your budget, comfort level with DIY projects, and the complexity of the job.

How to Measure a Roof for Shingles: 6 Steps

Accurately measuring your roof is crucial for purchasing the right amount of shingles and ensuring a smooth installation process. Follow these steps to measure your roof effectively:

1) Sketch Your Roof:

Start by drawing a rough sketch of your roof, including all sections and angles.

2) Measure the Length and Width:

Using a tape measure, determine the length and width of each section of your roof. Multiply the length and width of each section to calculate the area in square feet.

3) Account for Slope:

If your roof has a significant slope, you’ll need to adjust your measurements accordingly. Measure the slope’s rise and run to calculate its pitch angle, then use a roof pitch multiplier to adjust your square footage calculations.

4) Calculate Total Area:

Add up the square footage of each section of your roof to determine the total area that needs to be covered with shingles.

5) Factor in Waste:

It’s recommended to add around 10% to 15% to your total square footage to account for waste and cuts during installation.

6) Consult a Professional:

If you’re unsure about any aspect of measuring your roof, don’t hesitate to seek guidance from a roofing professional.

By following these steps, you can ensure that you purchase the correct quantity of shingles for your roof.

How to Install Shingles

Once you’ve measured your roof and purchased the necessary materials, it’s time to begin the installation process. Here’s a basic overview of how to install asphalt shingles:

Prepare the Roof: Start by removing any old shingles, nails, and debris from the roof surface. Inspect the roof deck for damage and make any necessary repairs.
Install Underlayment: Lay down a layer of roofing underlayment to provide an additional barrier against water infiltration.
Start with Starter Shingles: Begin at the bottom edge of the roof and install starter shingles along the eaves. These shingles provide a secure base for the rest of the shingles.
Apply Shingles: Working from the bottom up, apply the shingles in rows, staggering the joints to create a uniform appearance. Nail each shingle in place using roofing nails, following the manufacturer’s guidelines for placement.
Install Flashing: Install flashing around roof penetrations, such as vents and chimneys, to prevent water from seeping into the roof.
Finish with Ridge Shingles: Once you’ve installed the field of shingles, cap the ridges of the roof with ridge shingles for added protection and a finished look.

Throughout the installation process, be sure to follow all safety precautions, including using proper footwear and fall protection equipment.

The Cost of Installing Asphalt Shingles:

The cost of installing asphalt shingles can vary depending on factors such as the size and complexity of your roof, the quality of materials used, and whether you choose to DIY or hire a professional. On average, homeowners can expect to pay between $3 and $7 per square foot for asphalt shingle installation.

For a typical 2,000 square foot roof, this translates to a total cost of $6,000 to $14,000. Keep in mind that this estimate may not include additional costs such as roof repairs, removal of old shingles, or upgrades to premium shingle options.

While asphalt shingles are a cost-effective roofing option, it’s essential to weigh the upfront investment against the long-term durability and performance of the materials.
