If you have wood siding on your home, you have to keep an eye out and make sure that it doesn't develop any areas with rot. If you discover rotten wood siding on your home, it is important to address the issue right away. 

The Importance Of Removing The Rotten Wood Siding

When you spot rotten wood siding, it is important to act quickly, as rotten wood siding can have some serious side effects and consequences. If the rot is allowed to continue to grow and develop, it can spread and damage more of your siding, and it can even spread to the wood frame of your house and even damage the drywall on your home if left alone for long enough.

Additionally, rotten wood siding is often found near the roof line. Excessive water dripping down the side of your house, from a clogged or damaged gutter, can quickly cause your wood siding to develop rot issues. When wood siding near your roof starts to rot, not only is your siding in danger, but your roof is in danger as well. If the rot spreads to your roof, it will compromise the integrity of your roof. As your roof rots, the wood will break down and your roof will start to leak, which can lead to mold and mildew issues. Roof rot eats at not just the surface of your roof, but the entire structure and frame of your roof. The rot can spread from your roof and damage the frame of your home. 

Leaving rotten wood siding untreated can lead to the rot spread to your roof and to the frame of your house, destroying your home from the inside out. 

#1 Cut Away The Damaged Area

The first thing you need to do is remove the area where the rot is present on your siding. You are going to want to cut away all the visible rot, as well as a few inches past where you can see the rot. This will help ensure that you cut away all of the rot and get rid of all of it.

A great tool for removing the rotten siding from your home is an oscillating saw. This type of saw is great because you can use it in small areas to make plunge cuts, which are the type of cuts you'll be making as you remove the rotten siding sections from your home. Be careful and make sure that you only cut as deep as the siding. You don't want to cut the plywood sheeting that is under your siding.

After you cut the siding, you may still need to use a crowbar to pry the siding off the wall. You may also need to remove any loose nails from the siding

#2 Remove All Nails & Siding

After you cut the siding, you may still need to use a crowbar to pry the siding off the wall. You may also need to remove any loose nails from the siding as well before you remove the siding.

#3 Find The Right Replacement Clapboard & Paint

Now you need to purchase some clapboard to patch up the siding. You may want to take a chunk of the siding you pulled off of your home to the hardware store with you so you can match the style and design of the wood siding as close as possible with your replacement material.

You are also going to want to purchase some paint as well that matches your siding. That way, when you are done with the repair, you can make the patch blend in with the rest of your siding.

#4 Cut & Prime The Clapboard

Once you get the clapboard home, you are going to want to cut the clapboard down to size so that you can use it to fill in the space where you removed the rotten wood. You can use your osculating saw again to cut the clapboard or you can use a hand saw as well; either should work.

After you cut the clapboard down to size, you are going to want to apply bare wood primer on all sides of the clapboard, including the top and bottom, front and back, and the edges of the clapboard. This will seal the clapboard and ensure it doesn't rot as well.

#5 Paint The Clapboard

After the primer has dried, you are going to want to paint the clapboard the color of the siding on your home. You may need to apply a few coats of paint. Even though only the outer side and edges of the clapboard will be visible, paint all the sides. This will help seal up the clapboard even more and ensure that it never starts to rot.

#6 Install It With Acrylic Latex Caulking

Now that the clapboard has been painted on all sides, it is time to attach it to your home where you cut away the rotten siding. You are going to want to use acrylic latex caulking to attach the clapboard to the area where you cut away the rotten siding. Put lines of caulking all around the edge of the clapboard and down the middle. Push the clapboard into place and hold it while the caulking dries and allows the clapboard to attach to your home.

#7 Secure With Nails

Finally, secure the clapboard in place with some nails. This will ensure that the caulking dries and cures and that the replacement clapboard doesn't fall off your home.

If you see any rotting siding on your home, be sure to follow these steps right away. Rot can quickly spread if you don't get rid of it and compromise all of your siding. By following the steps above, you can stop the rot in its tracks and protect the wood siding on your home. You can also hire a roofing contractor to address the rot in your wood siding for you if you don't have the time to complete the steps above. A roofer can also ensure that the rot has not spread to your roof. If rot is found on your roof, a roofing contractor can take steps to stop it in its tracks so that the rot doesn't destroy the rest of your roof and your home.
