How to Lay Roofing Shingles

how to lay roofing shingles

Before you start laying the shingles, you should have a clear understanding of the technique. It is vital to follow instructions carefully and to consult a professional. It is also important to use proper nails. When laying roofing shingles, be sure to use nails that hold the top edge of the shingles. Also, nails should be set two inches apart and one inch above the cutouts. The next course of shingles should cover the nails by one inch vertically.

Before you begin the process, you must have a solid idea of how many shingles you need. To determine the proper amount of shingles, measure the height of the roof and the area of the roof. Remember to add 10 to 20% for waste. Also, remember to wear safety gear while on the roof to protect yourself. Make sure to hire a partner and a few helpers for the project. Also, follow manufacturer’s guidelines and adhere to a pre-planned layout.

First, lay down the felt roof underlay. Use a small piece of plywood as a guide. Then, apply roofing nails to the plywood or felt. Use cap nails instead of flat nails because they have a large nail head and a tack in the middle. This type of nail will not tear the felt. In addition, you’ll have a better chance of covering the entire roof. It is also important to use a level and a chalk line to ensure a straight line.

Moreover, it is important to consider the shingle course layout. If the shingles aren’t placed properly, the resulting seams may cause leaks. This happens because the shingles do not overlap each other but butt together. This makes them prone to leaking and may result in a weakened building. As you can see, shingle courses should be laid one on top of the other in order to avoid leaks.

Once the seams are prepared, you can lay the underlayment. If you’re doing it yourself, you can use a No. 15 felt, although some codes call for No. 30 felt. Ensure that each layer overlaps the lower one by two inches. You can also install drip edges. Finally, you can begin laying the roofing shingles. It’s important to follow the process correctly to avoid problems and increase the appearance of the roof.

Before laying roofing shingles, you need to install underlayment. Make sure to use 28-gauge galvanized metal for the valley. This reinforces the roof, so it won’t rot. To protect the roof from water damage, you should install a metal ice and water protector membrane. The ice and water protector membrane should be applied where the shingles meet the walls and around chimneys. You may also need to install metal flashings around these tricky areas.

Once the shingles are laid properly, you can move on to finishing the roof with a fresh coat of paint or a new coat of paint. For a more professional look, you can paint the roof with a neutral color and apply a protective coating. In this way, you won’t have to worry about water damage and mold. If you’re installing a new roof, it’s important to take care of its preparation.
