Causes of Roof Granule Loss

Asphalt shingled roofs contain tiny granules that reflect sunlight. This helps reduce sun damage to the roof and ever so slightly improves insulation. Roof granules are washed away and deteriorate over time. When there are not enough roof granules on the roof, there is a greater chance that the roof will suffer damage and begin leaking. It is important to maintain your roof to reduce the amounts of damage it endures.

If your roof needs repairs or to be completely replaced, look no further than an Austin roofing contractor of AAA Mustang Roofing. Our experienced professionals are prepared to help you to counteract granule loss. Contact us at 512-650-9866 for a free estimate.

Roof Granule Loss

There are many reasons a roof might be losing its granules. While some granule loss is to be expected, it should not be enough to put your roof in danger of losing years off of its expected lifetime. On a brand new roof, loose granules will wash off when it rains. This is totally normal. They will be easy to find in and at the end of your gutters. Some other causes of granule loss include:

  • Walking on the roof
  • Hail damage
  • Defective shingles
  • Roof blistering

The granules on asphalt shingles protect them from becoming damaged and leaky. If your roof’s shingles look like they have lost the vast majority of their granules, it may be time to replace them.

I first became acquainted with Zane Nixon, owner of AAA Mustang Roofing, when our metal roof was severely damaged in a hailstorm. Our house is large and has over 30 separate roof surfaces, with an equivalent number of edges and valleys. Zane and his crew completed the work in less than two weeks, and it is flawless. They even repaired several areas that suffered structural damages.

Just recently a flash flood on the day following hurricane Hermine caused significant damage to the first story of the house. I called Zane and he was here within 30 minutes and stayed until midnight. Using squeegees, towels and a shop vacuum, we managed to save the rugs and furniture. However, the walls required substantial repairs. Zane worked closely with our insurance adjuster, and the wall repair work under his guidance as contractor is every bit as professional as his previous work.

I recommend AAA Mustang without reservation for any type of construction or remodeling job.
