Understanding Shingle Granules

Roof shingle granules are small, mineral-coated particles that play a vital role in protecting and enhancing the appearance of asphalt shingles. These granules are available in a wide range of sizes, shapes, and colors, providing durability and adding a touch of uniqueness to your roof, making it a beautiful masterpiece. At RoofShield, we understand the significance of these granules and their role in prolonging the lifespan of your roof.

Causes of Granule Loss

Granule loss on your roof can occur due to various factors:

  1. Normal wear and tear over time, as your roof is exposed to harsh weather conditions like rain, hail, snow, and the sun’s UV rays, can lead to gradual granule erosion.
  2. Manufacturing defects may also cause premature shedding of granules, leading to concerns soon after installing a new roof.
  3. Excessive foot traffic on the roof, especially during maintenance or repairs, can dislodge and damage granules, further affecting the overall protection of your roof.
  4. Hailstorms can be particularly harsh on roofs, causing granules to dislodge upon impact, leaving your shingles exposed and vulnerable.
  5. Moss and algae growth on the roof, especially in damp and shaded areas, can lift and dislodge granules, compromising your roof’s protective capabilities.
  6. Improper roof installation can lead to loose granules, making your roof susceptible to damage.

At RoofShield, we understand each of these causes and can provide tailored solutions to address granule loss effectively.

Signs for Repair or Restoration

Determining the appropriate action for granule loss depends on several factors. Firstly, consider the age of your roof. If your shingles are nearing or past their expected lifespan, widespread granule loss may indicate the need for a complete roof replacement. Secondly, evaluate the extent of the damage. If granule loss is limited to a few isolated areas or individual shingles, restoration may be in order. However, if the granule loss is extensive or exposes the underlying layers of your roofing shingles to the elements, replacement may be the best course of action. Signs such as leaks, water stains, curling or buckling shingles, consistent granule accumulation in gutters, or moss and algae growth require professional attention. At RoofShield, we have a team of experts to inspect and assess the situation to provide you with the most suitable solutions.

Handling Granule Accumulation

As your asphalt shingles age, finding some granules in your gutters and downspouts is normal. These granules gradually shed over time due to normal wear and tear. However, if you notice a significant accumulation of granules in your gutters or around the base of your downspouts, it could be a sign of excessive granule loss. This might indicate that your shingles are reaching the end of their lifespan or that there is an issue with the shingles, such as manufacturing defects or damage from weather events like hailstorms. In such cases, a professional must inspect your roof to determine the cause and assess whether repairs or restoration are necessary. If restoration and rejuvenation are possible, a single treatment with Roof Shield’s asphalt shingle rejuvenator, Roof Reboot will stop further granule loss and extend the lifespan of the roofing system.
