How many inches of shingle should be exposed on the first row of shingles?

  1. 3

  2. 4

  3. 5

  4. 6

The correct answer is: 3

For the first row of shingles, it is important to expose the correct amount of the shingle to ensure proper coverage and protection from the elements. The recommended standard exposure for the first row of shingles is about 3 inches. This allows for enough coverage while also making sure the shingles are properly secured in place. Exposing too much or too little of the shingle can lead to potential issues such as leaks or poor wind resistance. Therefore, ensuring 3 inches of shingle are exposed on the first row is the correct practice in shingle installation.
