3. Making Woods Last Long

But, if you have a cedar siding underlayment in your roofs, it’ll provide great insulation. Here, the improved insulation makes sure that less heat is transferred. Hence, it’ll keep the roofs cool in summer and warm in winter.

The cedar siding underlayment ensures low density on the roofs. As a result, it makes the product have a great acoustical barrier.

Step 1: Install the Siding on the Corners

Firstly, you’ll have to install the siding into the corners of your home. So, take the siding corner trim and secure it on the corners of the roof.

Step 2: Secure the Boards & Fill Any Joints

Following the 1st step, use the hammers and nails on the corner boards. Using the hammer, make sure that the board is secured in its place. The boards should be flush to the home before you nail them in.

After you’re done, fill in the joints so that you can seal the boards in. Here, you’ll have to use caulk to seal the joints and also fill them.

Step 3: Measure the First Side and Cut the Strips

Take the measuring tape and measure the lengths of the first side. After this, you’ll need to cut the strips. Here, make sure you’re cutting the furring strips to span the length.

Also, go according to the measurement and double-check to ensure that you don’t mess anything up.

Step 4: Attach Furring Strips & Cut the Cedar Pieces

Before cutting the cedar siding pieces, attach the furring strips to the bottom. Here, you’re attaching so that it acts as a support to the first board.

After you’re done with this, take the table saw and cut the cedar pieces. The pieces need to be cut according to the length of the roof.

Step 5: Install the 1st Piece of the Cedar Siding to the Home

Start by installing the first piece to the bottom of the home. You’ll have to overlap the strip to one inch. Make sure it doesn’t get passed 2 inches. Following this, continue going with the first piece installed.

Step 6: Continue Layering & Cut the Siding to Fit the Shape

Layer the pieces so that they are vertically installed in the home. However, make sure that you’re giving about ¼ inch of a gap. You’ll have to provide the gap in the last board.

After you’re done giving the gap. Seal it with molding. Also, if you come around any windows then cut the siding with the table saw so that it can fit. By doing this, you’ll provide good shape and it’ll look good to the eye.

Repeat the process in the same manner until you cover the whole house.

Bonus Tip

  • In order for the siding to look good, don’t install the pieces in the same way as the others.
  • The length of the layered pieces shouldn’t be the same as the others.
  • The seams shouldn’t be positioned on top of each other.

Cedar Siding Installation Best Practices

The cedar siding is great for homes as it’ll bring character and durability. Moreover, it even makes the homes look great and provides long-lasting shine. So, we’ve introduced you to the easy DIY installation of cedar siding.

Now, let’s take a look at some of the best practices for cedar siding installation:

1. Let the Siding Breathe

You need to flex the cedar once after installing it. This is a type of material that needs flex and breathing. So, it’s highly recommended you install this material over furring strips.

If you’re installing this horizontally, the strips should be attached vertically. And, if you’re installing them vertically then attach the strips horizontally.

As a result, you’ll give them space to flex and breathe. Also, the moisture will make sure they’re not in contact with the wall at any time. The sidings absorb moisture. So, you need to provide papers to cover them up.

Also, you can use a cedar breather. This provides a continuous airflow between the roofs and the shingles. As a result, it’ll cause the cedar siding to breathe.

2. Nails for Cedar Siding

Make sure the nails are penetrating two inches into the studs and the strips. Also, use galvanized nails for this. Apart from this, use thin nails so that they don’t split the woods at the time of installation.

On the other hand, keep the nails away from one another. If they’re close to each other, they’ll stop the woods from flexing.

3. Providing Cuts to Cedar Siding

Take a normal hand saw and miter box to provide cuts into the cedar siding. But, why is it needed?

Well, cutting the ends will make sure it doesn’t get attacked by insects. Even though cedar siding is naturally resistant to insects, it can still harm it. So, it’s better if you take the precaution.
