How to Lay Roofing Shingles
To learn how to lay roofing shingles, you need to measure the area that needs to be covered, and then start by laying the shingles. You should then cut a small section of the first row of shingles, about 6 inches wide, and place it next to the first. You can then nail the shingles down as you go, making sure that they are evenly spaced apart. The next step is to overlap the first row by one-half inch, or roughly 1.27 cm (about 30.4 centimeters) and the last row of shingle. After you’ve completed this, you should cut the shingle to fit in between the two previous rows.
You can now proceed with the next step, which is putting down the shingles. After placing the first row, you should lay the shingles in the valley. Start the shingles in the valley with the lower shingle, and then place the shingles on the other side of the ridge. Make sure that each shingle overlaps the previous row by 12 inches. Once the rafter is covered, you can move on to the next step.
To lay the shingles in the valley, measure the length of each ridge and hip and divide it by 35 to get the number of bundles you need. Once you have the number of shingles you need, you can divide the ridge cap by three and use this as your guide to measure the length of the shingle. You should now measure the shingles in the valley using a tape measure. When you have determined the length of each row, you need to measure the length of each notch. You can also use a chalk line to determine the center of the ridge and use it as a measurement for cutting the shingles.
To lay the shingles in the valley, you should begin installing the shingles away from the valley. If you need to make adjustments, you can always cut six inches off the shingles, which will prevent them from lining up properly. In this case, you will have to start from scratch by laying another full shingle. If the roof is gable, you must start with the left side of the gable, then repeat the process on the other side.
The first row of shingles should be placed at the ridge. It should be flush with the first row. The next row should be nailed with four nails, while six nails are preferred for windy areas. After you have finished with the first row, you should start laying the shingles. If there are any ridges, you should nail them with the last shingle. This should be about six inches apart.
