When to Replace Siding on a House

Siding is a vital part of your home’s exterior – but how do you know when to replace it? Siding provides your home with many things; it maintains energy efficiency within the home and contributes to curb appeal. Now let’s find out if it is time for your home to take a new look.  

How Long Does Siding Last on a House?

The lifespan of siding for a home usually depends on the material used to build it, climate conditions surrounding the home, and maintenance habits to keep up with it. The following sections list the types of lifespans for specific siding types and what factors impact the longevity of siding.   

Lifespan by Siding Type  

It is very common for many homes to use vinyl siding; it is low maintenance and there is a visual appeal. But there are other options out there that could save you money in the long run. Most importantly there is much less upkeep and worry about whether or not it needs to be replaced any time soon.  

  • Engineered wood- 20 to 30 years 
  • Vinyl – 20 to 40 years  
  • Wood –20 to 40 years  
  • Aluminum- 20 to 40 years  
  • Fiber cement –50+ years 

Factors that Impact Siding Longevity  

Life happens and at times keeping up with siding is the last thing on our minds. But we are here to change that. Weather can be unpredictable wind can get caught under siding and rip it off and sometimes outdoor equipment (i.e. lawnmowers, snowblowers) can cause unexpected damage. Many factors impact how long siding lasts, and we are here to help you stay ahead of them. Here are some common factors that can impact the lifespan of your siding:  

  • Climate  
  • Sun Exposure  
  • Moisture levels  
  • Nearby trees or pests 
  • Installation quality  

9 Signs it is Time to Replace Your Siding

It is not uncommon that new siding is occasionally put on the back burner while roofing, and other home maintenance projects are prioritized. However, often times siding should be replaced before your roof. Most times warning signs creep up unexpectedly and gradually, which makes it so important to stay diligent and remain aware of the state of your siding. If not taken care of promptly, it can affect the appearance and structural integrity of your siding. So, keeping your eye out for any of these deteriorating siding signs is very important for the safety of your home and wallet.

1. Cracks, Warping, or Holes

Any visible cracks, warped boards, or punctures in your siding can allow moisture to get behind it, leading to serious structural issues. If you are able to feel the back layer behind your siding – that is a big red flag which needs to be addressed immediately.   

2. Mold, Mildew, or Rot

When you spot organic growth (i.e., mold or mildew) on your siding, it often signals trapped moisture and hidden damage, especially around the seams or the base of your home. If the siding starts to crumble as it is touched or it looks like it is rotting, it is likely to be another sign of organic growth that needs to be addressed. 

3. Fading Color and Peeling Paint

If you have noticed that your siding frequently peels or is faded, then that may mean you are due for a replacement. The protective coating that lines the siding has worn off, therefore reducing any weather resistance it may have.

4. Bubbling or Blistering

Bubbling or blistering on siding typically indicates that moisture has become trapped behind the siding. It is important to address this as soon as possible, because once moisture gets trapped, it creates a perfect environment for mold and mildew to grow.

5. Loose or Missing Panels

If any siding panels are visibly detached, it risks exposing your home to pests, drafts, and water damage which needs to be addressed quickly. Even minor gaps can lead to much bigger problems over time, so making early repairs ensures your home will remain protected.  

6. High Energy Bills or Drafts

It may not be your first thought, but abnormally high energy bills are a sign that new siding may need to be on your radar. There is a possibility that your siding is failing or poorly insulated, spiking energy costs.   

7. Moisture Damage Inside Your Home

Peeling paint or warped drywall on the interior walls of your home can mean serious damage to the siding of your house.  Water may be entering through compromised siding which needs immediate attention.

8. Pests or Insect Intrusion

Cracks or gaps in your siding can lead to serious damage. Insects, rodents, or birds can enter and nest within open spaces which can cause further harm to the walls. The longer you wait before removing any sort of pest, the more expensive the work becomes. Acting quickly will help prevent small problems from becoming bigger ones.  

9. Frequent Repairs or Maintenance

Siding doesn’t last forever. If you find yourself replacing or repairing your siding more than usual, it might be time to do a full replacement. Constant upkeep or repainting can cost a lot, and replacing all of the siding one time is more cost effective.

Should You Repair or Replace Your Siding?  

Deciding whether to repair or fully replace your home’s siding is an important consideration as a homeowner. If you are unsure where to begin, an extensive whole home evaluation is a great first step. Ask yourself: Is the damage extensive? What is the required maintenance? Immediate action is necessary, but it is also important to consider the long-term. Does your siding match others around you? What is the current home trend? How long do you plan on staying in your home? It is not an easy decision to make. Many people ask themselves the same questions, so don’t worry, you are not alone.

Can It Be Fixed?

Curb appeal is key for maintaining your home’s value and appearance. Whether you are staying in your home or considering selling, your siding plays a crucial role. If you notice any issues, the next step is figuring out whether it can be fixed with a small repair or if a full replacement is needed. To determine if your home siding is eligible for repair, ask yourself these questions: Is the damage just a small crack? If there is rot, is it only isolated to one area of the house? Are only a few panels loose? If your answer is yes to any of those questions, then you might be able to fix your siding at a lower cost.

The Cost of Piecemeal Repairs Overtime

If you have noticed you keep returning to the same problems with your siding, it might be time to think about a full replacement. Individual repair overtime may seem cost-effective at first but looks can be deceiving. The cost of repairing multiple times can add up quickly, especially if the problems keep returning. We recommend that homeowners should consider the long-term investment of a full replacement if you know your siding has been around for a while or been damaged extensively. It saves you and workers time and money, but most importantly protects your family from any harm.
