At some point or another, all of us will need to replace our roofs. But, with certain roofing types, it is easier to identify when it is time to bite the bullet than it is for others.

Asphalt shingles have been a popular roofing material for decades due to their affordability, durability, and ease of installation. However, like any roofing material, they are susceptible to wear and tear over time. One common issue that homeowners face with asphalt shingles is granule loss.

In this blog post, we will explore:

  • What granule loss means
  • Signs that may indicate a need for roof replacement
  • Costs associated with asphalt shingle roof replacement
  • Tips on maintaining the health of your roof

Keep reading to learn what granule loss on shingles means.

What Is Granule Loss on Asphalt Shingles?

Granule loss refers to the gradual wearing away of the small, granular particles on the surface of asphalt shingles. These granules are primarily responsible for protecting the shingles from harsh elements, including:

  • UV rays ☀️
  • Rain 🌧️
  • Hail 🧊
  • Snow ❄️

When granules start to erode, the shingles become more susceptible to damage and deteriorate at a faster rate. You may notice granules in your gutter or on the ground around your home, signaling that your shingles are losing their protective layer. They tend to look like small black rocks or sand.

Signs You May Need a Roof Replacement

Granule loss is just one of the signs that your asphalt shingle roof may need replacement. Here are some other indicators to watch out for:

  • Age of the Roof: Most asphalt shingle roofs have a lifespan of 20 to 25 years. If your roof is approaching or has exceeded this timeframe, it’s essential to start considering a replacement.
  • Curling or Buckling Shingles: Shingles that are curling at the edges or buckling in the middle are a clear sign of weathering and aging. This allows moisture to seep underneath, causing further damage.
  • Missing Shingles: If you notice missing shingles or significant areas of damage, it’s a sign that your roof’s integrity is compromised, leaving your home vulnerable to leaks and water damage.
  • Sunlight in Attic: During a sunny day, check your attic for any streams of light filtering through the roof. This indicates that there are openings where water can penetrate.
  • Water Stains on Ceiling: Water stains on your interior ceilings or walls can be a sign of roof leaks, requiring immediate attention.
  • Excessive Moss or Algae Growth: The presence of moss or algae on your roof can damage shingles and hold moisture, accelerating the deterioration process.

Asphalt Shingle Roof Replacement Costs

The cost of replacing an asphalt shingle roof varies based on factors such as the size of your home, the complexity of the roof design, the region you live in, and the quality of materials chosen. On average, you can expect to pay between $8,000 to $12,000 for a standard-sized home. The costs can increase if your roof requires additional structural repairs or if you opt for premium shingle options.

While it may seem like a significant investment, a new roof can add value to your home, enhance curb appeal, and, most importantly, provide reliable protection for years to come. Additionally, some roofing contractors offer financing options to help spread out the cost.

6 Tips for Maintaining the Health of Your Roof

To extend the life of your asphalt shingle roof and reduce the need for premature replacement, regular maintenance is crucial. Here are some essential tips to keep your roof in top condition:

1) Regular Inspections

Perform visual inspections of your roof at least twice a year, ideally in spring and fall. Look for signs of damage, loose shingles, and granule loss. Address any issues promptly to prevent further deterioration.

2) Keep Gutters Clean

Clogged gutters can cause water to back up and seep under the shingles. Clean your gutters regularly to ensure proper drainage and prevent water damage.

3) Trim Overhanging Branches

Overhanging tree branches can scratch and damage shingles during storms. Trim back branches to minimize potential hazards.

4) Address Moss and Algae

If you notice moss or algae growth on your roof, remove it carefully to prevent further damage. Avoid pressure washing, as it can dislodge granules. Instead, use a mild bleach solution or specialized roof cleaning products.

5) Ventilation

Ensure your attic is properly ventilated to reduce heat buildup in the summer and minimize moisture retention in the winter.

6) Professional Roof Inspections

Have your roof inspected by a professional roofing contractor every few years or after significant weather events to detect any hidden issues and address them promptly.
