In order to apply the granules, we should observe the surface of the roof first. If the surface is slippery, then for every 100 square feet of roof, it is required to use 40 lbs of granules.

Step 4: Grit

Step 5: Drying

Usually, there are three coats in this process-based coat, finish coat and adhesive coat. Firstly, the base coat and the finish coat need to be allowed for drying at least for three to four days. Then the third coat which is known as the adhesive coat should be applied.

In the process of coating, when the third coat remains wet, then the roofing granules must be spread evenly for better functionality. Here, it is highly recommended to do only one segment at a time.

Step 6: Loose granules

We already know that the roofing granules are made out of crushed stones and minerals. With the passage of time, some granules may fall or we call it loose from the layer of asphalt which can cause damage to your roof.

But here, after the coating is dried up, you can take a blower to eradicate the loose granules from the surface. Then after recovering, you can reuse it to the layer on the rest of the roof.

Losing granules is common from the asphalt layer similar to bitumen membranes. Especially if you walk barefoot on the surface of the coat, then the granules gradually penetrate the membrane of the coating.

It is highly recommended to use walk pads specifically for the areas which need to be maintained heavily. Usually, asphalt shingles have three layers.

  • The first layer is backing material,
  • The second one is an asphalt layer,
  • And the third one is an outer layer of granules.

So by following the above-mentioned steps carefully, you can maintain your roof for a longer period of time.
