How to Repair Granular Loss on Roof

Date: March 16, 2023

It is important to identify and repair granular loss on your roof as soon as possible in order to prevent further damage and preserve the lifespan of the roof. Repairing granular loss on the roof can be done in a few steps that are relatively easy and cost-effective. In this article, we will discuss what granular loss is, how to recognize it, and the steps needed to repair it.

What are Roof Granules?

Roof granules are the small pieces of stone or mineral material that make up the surface of a shingled roof. They are designed to protect the roof from weather and wear but can be lost over time due to heavy rains, ice movement, debris, animals, or people walking on the roof.

What Causes Granular Loss on Roof?

Granular loss is one of the most common roofing problems that homeowners face. The cause of this problem is the asphalt in the shingles drying out, which weakens its grip on the granules. As these granules become loose they can be blown off in high winds leaving your shingles vulnerable to damage.

Identifying the cause of this will help to prevent further damage from occurring and allow for necessary repairs to be made. This involves checking your roof for any missing or damaged shingles. If there are any visible signs of wear and tear, then it’s likely that some of the particles have been lost from the surface of your roofing material.

Without proper maintenance and repair, the granular loss can lead to further damage and even water leaks, resulting in costly repairs. It also decreases the life expectancy of the roof by allowing water and moisture to penetrate under the shingles.

What are the signs of Granular Loss on Roof?

Checking for signs of granular loss is an important part of roof maintenance

  • Dark patches on the roof are one of the most common signs of granular loss. You might also notice that some parts of your roof are darker than others due to granules being lost or rubbed off by wind and rain.
  • Additionally, if you look closely, you may find granules in your gutters or at downspout locations near your home.
  • Another sign of granular loss is when the ends of shingles become shiny or the fiberglass is already showing up.

By understanding these signs you can easily identify problems and take corrective measures before further damage occurs. If any of these signs are present on your roof, it’s time to call in a professional to inspect and repair the damage.

Why is Granular Loss on Roof Bad?

Granular loss is a serious issue for homeowners because it can lead to significant damage and costly repairs. Missing granules reduce the life expectancy of shingles, as they are no longer able to protect against water and other elements. This can cause water damage or even leakage into your home, resulting in expensive repairs. Without granules on your roof, it is more difficult to detect signs of wear or future problems that may require maintenance or replacement.

Can you Repair a Granular Loss on Roof?

Unfortunately, granule loss is one of the most common signs that a roof needs to be replaced. Some companies have taken to using silicone coatings to spray the roof with a water/silicone combination, hoping to bring back moisture into the asphalt shingle. But it does not replace the granules that wear away on the roof surface due to erosion and other factors. Without those granules, the roof can be more vulnerable to further damage from sun exposure and moisture that can penetrate through the coating.

The best solution for dealing with this is to take a proactive approach and monitor it closely. If you notice granules coming off the outside of your roof or in your attic, then it may be time to take action. Replacing the entire roof is the most economical solution. This will save you money in the long run and will reduce the need to repair portions or coatings that may become worn over time.

How Can You Prevent Granular Loss on Your Roof?

Keeping your roof in good condition is important for preventing granular loss and ensuring your home is protected from the elements. There are some steps you can take:

  • Regularly inspecting and maintaining your roof

A thorough roof inspection should include checking for cracked, missing, or loose shingles, as well as inspecting flashing and other materials around vents, skylights, and chimneys. Regular maintenance tasks like clearing debris from gutters, sealing seams around chimney flashings, and trimming trees close to the house should also be done to keep your roof in top condition.

  • Ensuring proper ventilation

Proper ventilation is essential for preventing granular loss. Without proper ventilation, the temperature of the roof can become too hot and cause the asphalt shingles to deteriorate faster. This can make them more prone to breakage and cracking, leading to granules being washed away with rainfall.

To ensure proper ventilation on your roof, you should make sure that there are adequate intake vents at the bottom of your roof and exhaust vents at the top. You should also check that these vents are not blocked by insulation or other materials that could hinder airflow.

  • Proper drainage systems

The proper installation of a drainage system is essential for preventing granular loss on a roof. These systems help to direct water away from the roof, minimizing the amount of damage that can occur due to water accumulation. They also provide an effective way to reduce the risk of ice dams forming on the roof in colder climates.

Proper drainage systems can also help reduce the amount of granular material that can be lost due to wind or rain. By installing a reliable drainage system, you are taking steps towards protecting your investment and ensuring that your roof lasts as long as possible.

  • Replacing damaged or worn-out shingles

The granules found on the surface of the shingles can be lost over time due to weather conditions, age, and other factors. Replacing these shingles helps protect the roof from further damage and keeps it water-tight. This will also help maintain the aesthetic appearance of your home. It is important to inspect your roof on a regular basis in order to detect any signs of granular loss or damage before they become too severe.

Doing these tasks regularly will help maintain the longevity of your roof and keep it functioning efficiently over time. Most importantly, talking to a professional roofing contractor for regular maintenance will help make sure any potential issues are addressed immediately and prevent granular loss from occurring.
