For an exterior corner, nail one shingle flush with the corner edge of the sheathing. The shingle meeting it from the other side will overlap this one. Nail the overlapping shingle. The excess wood is cut off with a hatchet, as shown in Figure 7. Interior corners are handled in the same way. The only difference is that instead of nailing the second shingle and cutting it in place, it is held in place and scribed.
It is then cut and nailed in place. Figure 1 - Cedar shingle siding There are several things you should be aware of before installing shakes or shingles. Figure 5 - Mounting straight wood board Nail the board in place aligned with the chalk line. Figure 6 - Aligning board with foundation chalk line The reason for using the bottom of the shingle as a measuring point rather than the top is that shingles may vary slightly in length.
Use two nails for shingles 8 inches wide or less and three nails for wider shingles. Cedar shingles are quite thin and can be accidentally split by a fastener.
To begin a wood shake siding installation, the first step is to measure how much siding you will need to cover the area. This is done by multiplying the width of the area by the length.
To illustrate, if a wall is 8 feet high and the area to be sided is 20 feet long, the total area will be about square feet. This process is then repeated everywhere siding will be installed. Once you know how much you need, the next step is to decide the details, like the profile shape and the wood species available. Pro Tip. Professional cedar shingle siding installers will often do one wall at a time. This helps speed up the project because it prevents moving the tools and ladders any more than necessary.
Cedar shingles require some form of underlayment to deflect rainwater from getting behind the siding. This is important because the main concern with natural materials is their propensity to rot. Cedar shingles will perform best when they not only stay dry on the backside, but can also dry out if they do. This is essentially a large mat, which resembles a large scrubbing pad.
This allows air to circulate behind the shingles, evaporating any moisture. These mats are usually installed with roofing tacks or staples, but any fastener must be galvanized against corrosion. Professionals will often begin a project by setting up their work area. In most cases, there will be one person who makes cuts and notches, while two others do the measuring and install the material. Cedar shingle siding is unlike synthetically manufactured materials, in that it will not include some form of guide or lock to ease installation.
If the reveal is larger, less material will be needed. By the way, it is a good idea to purchase an extra box of shakes from the same lot, as these will likely have come from the same logs.
Having an extra box is handy when shingles break or must be carved to fit. In a normal installation, the first step is to make a level line at the bottom of the wall everywhere the siding will be installed on the house. This level line is then squared to the vertical corner of the wall, establishing what is known as a plumb line. This plumb line will represent the location of the outside corners if the project will use them , which are often installed first. Cedar shingles often do not incorporate trim unless the siding will be adjoining a dissimilar material.
This is because the shingles are easily trimmed with just a sharp knife, giving the structure a very custom appearance. If the project will use trim, these plumb lines will become critical to keeping the project square.
This level line is usually made with a chalk line and represents the location of the first course. Many professionals will then use this line as a reference for the bottom of each shingle. However, some installers use a different method as they find it easier. Some installers will forgo the initial chalk line and simply nail a straight board to the bottom of the wall, about 2 inches below any masonry.
This board then essentially becomes a temporary shelf that the entire course of shingles can rest upon while they are attached.
This keeps the all-important first-course level and straight. The starter strip is installed next, and usually lines up with the bottom of the wall, 2 inches from any masonry, depending on the project. The starter board is just a very straight, horizontal board used to hold the first course in place and arrange the sequence of the shingles.
Since each shingle is often tapered, the starter strip is usually cut on site, with a small bevel. This bevel causes the shingles to flare out on this first course, which improves the look and keeps rainwater away from the structure. Cedar shingles are installed just like a roof shingle, from the bottom up.
Just like a shingle, the first course is a starter course and will usually be entirely covered by overlapping it with another course. This is the course that will be seen when the project is finished. This second layer is installed to cover the joints of the first layer, preventing water from penetrating the joint between the shingles. Most installers will begin the first-course using full-size, or half-size shingle and finish the course completely.
With some knowledge and skill, shakes can also be applied over existing siding. Shakes and shingles may be used to cover existing wood beveled siding, masonry, or stucco. Hot-Dipped galvanized, aluminum and stainless steel nails are all corrosion-resistant and all can be used to nail Western Red Cedar. Other types of nails are not recommended. They can rust and disintegrate and react adversely with the natural preservative oils present in cedar resulting in stains and streaks.
Since vinyl siding moves as the temperature changes, make certain that the panels can move freely in a side-to-side direction once fastened. Stagger the siding end laps so that no two courses rows of panels are aligned vertically, unless separated by at least three courses. Tando Shake and Shingle siding is a new-age siding that mimics the timeless look of cedar shake and shingles.
