Signs it is Time to Replace Your Siding

It may be easy to see some obvious signs when it is time to replace your siding.  Discoloration, cracking, or missing pieces can cause you to call a siding contractor right away.  There are some other signs that may not be so obvious to the naked eye, and you should be aware of these as a homeowner.

Heating or Cooling Bill Fluctuations

Mainly any increases in heating or cooling costs will be something to look for that can be a sign to replace your siding. While you may first look to your roof or attic, if these two places show no sign of issues, the next place to look is your siding. If cheap, or low grade, insulation was used, it can decrease the life of your siding which will cause your heating and cooling bills to rise.

Dry Rot

Dry rot is something you want to catch early. It is a good idea to periodically check for this problem by tapping on your siding with the rubber end of a tool. Even if your siding still looks pristine from the outside, it is very possible for it to be rotting underneath, which means your home is at risk. If you do notice any dry rot, it is crucial that it is replaced as soon as possible.

Warped Pieces

While this issue is able to be seen by the naked eye, you might not notice it without knowing to look for it.  If you see pieces that are not straight, or any that are clearly rotten, they should be replaced immediately. Unfortunately, if siding has been warped for awhile and has gone unnoticed, the layers underneath are probably becoming damaged. It is always best to catch this issue early on, so do a walk-around every so often to check for warped siding.


Bubbling siding is a huge cause for concern because it almost always means that there is water underneath. This can then cause mold and mildew issues.  What could be an easy fix could turn into tens of thousands of dollars if not corrected quickly.

There are many signs it is time to replace your siding. If you are unable to keep an eye on your home or are unsure if your siding needs replaced soon, have a reputable siding contractor do an inspection. It is always better to find out sooner than later to avoid more potential problems down the road.
